Balanced diet during weight loss medication therapy
During weight loss medication therapy, a balanced diet is not just about “eating less,” but primarily about “eating smarter.” Medications that suppress appetite, slow gastric emptying, or alter fat absorption can significantly reduce the amount of energy and nutrients delivered to your body. Therefore, every meal should be as “nutrient-dense” as possible – containing the maximum protein, fiber, healthy fats, vitamins, and minerals while being relatively low in calories. The foundation of your plate during weight loss medication therapy should be non-starchy vegetables (e.g., broccoli, zucchini, bell pepper, cucumber, tomatoes, lettuces, cabbage, cauliflower, green beans), which provide fiber, B vitamins, vitamin C, K, and antioxidants. Each main meal should have at least ½ a plate of vegetables in various colors, preferably as a mix of raw and cooked (e.g., a salad plus steamed vegetables), which improves both digestibility and nutrient absorption. The second pillar is high-quality protein, which helps protect muscle mass during weight loss, keeps you fuller for longer, and reduces the risk of hunger attacks. In practice, this means including a protein source in every meal: lean meats (e.g., chicken breast, turkey, lean beef), fish (especially fatty sea fish like salmon, mackerel, herring for omega-3s), eggs, fermented dairy products (plain yogurt, kefir, skyr, cottage cheese), or legumes (chickpeas, lentils, beans, tofu, tempeh). A good practice is to distribute protein intake evenly throughout the day (e.g., 20–30 g in each main meal), which is especially important if, due to the medication, you’re eating less volume-wise. Another key element of a balanced diet during weight loss medications are complex carbohydrates with low processing – whole grain bread, groats (buckwheat, barley, millet, bulgur), brown rice, whole wheat pasta, and oatmeal. Their high fiber content stabilizes blood glucose and sustains satiety longer, reducing the urge for sweets or quick snacks. People on appetite-suppressing medications often unconsciously limit their portions to a few bites; then, it’s wise to “densify” the meal with extra spoonfuls of groats, lentils, or oatmeal in a soup. Do not forget about healthy fats, essential for absorbing vitamins A, D, E, and K, supporting hormonal balance and brain function. Despite fears about fat, small amounts of good quality vegetable oils (rapeseed, olive oil, linseed for cold dishes), nuts, seeds (pumpkin, sunflower, sesame), and avocado should regularly feature in the diet. This is especially important with medications that reduce intestinal fat absorption—in such cases, the risk of deficiencies of fat-soluble vitamins rises, so ensure both their presence in the menu and the right distribution of fats throughout the day.
When planning a balanced diet during weight loss medication therapy, your daily structure and meal regularity, tailored to the drug’s mechanism and your wellbeing, is vital. Many people experience strongly reduced hunger in the morning or early day, with appetite increasing in the evening—in such cases, it is worth working with a dietitian to distribute energy intake to avoid late-night calorie compensation. A model of 3 main meals with 1–2 smaller snacks, each balanced (protein + vegetables/fruit + wholegrain carbs or healthy fats), often works in practice. If the medication causes nausea or heaviness after larger portions, smaller, more frequent but still nutrient-rich meals may be a sensible strategy—not based on snacks like crackers or sweet yogurts. Consider also meal consistency: with low appetite or gut sensitivity, vegetable cream soups with legumes, thick smoothies with natural yogurt, berries, and a spoon of ground flaxseed, or oatmeal on milk or calcium-enriched plant drinks, are often well-tolerated and can provide a full range of macro- and micronutrients. Another important aspect is product quality control: during weight loss medication therapy, highly processed snacks rich in simple sugars, syrups, hydrogenated fats, and salt (sweets, fast food, sweetened drinks, crisps, “fitness” bars with a long ingredients list) are particularly unfavorable. Replacing them with simple, natural foods—fresh or frozen vegetables and fruits, unsweetened nuts, natural dairy, cooked or baked meats, fish, or legumes—delivers many more vitamins, minerals, and fiber with similar calories. Be mindful of beverages: people on weight loss medications often “forget” to drink, which encourages constipation, headaches, and malaise. The best choice is water (with lemon, mint, or fruit slices), unsweetened tea, or herbal infusions; carbonated drinks, juices, and energy drinks should be minimized due to empty sugar load and glucose spikes. Maintaining a balanced diet is easier with meal planning—preparing meal plans for several days, cooking in batches, portioning and freezing meals, and keeping healthy “emergency” options at home, like hummus, crunchy vegetables, plain yogurt, a handful of nuts, or whole grain bread. That way, even with reduced appetite, tiredness, or medication side effects, you can easily reach for something valuable, instead of giving into impulse and choosing the most processed, nutrient-poor products.
Enriching the diet with fresh vegetables and fruits
During weight loss medication therapy, fresh vegetables and fruits become the foundation of a healthy menu, as their small calorie content brings plentiful vitamins, minerals, fiber, and antioxidants, helping to prevent deficiencies despite reduced appetite. A well-assembled “rainbow” plate can minimize the risk of shortages of nutrients such as vitamin C, folic acid, potassium, magnesium, or beta-carotene, while also supporting the digestive system, which, in some people on weight loss medications, responds with constipation, bloating, or diarrhea. Particularly important are non-starchy vegetables: greens (spinach, kale, lettuces, broccoli, zucchini, cucumber, green bell pepper, Brussels sprouts), reds and oranges (peppers, carrots, pumpkin, tomatoes, beets), and cruciferous veggies (cauliflower, broccoli, cabbage, Brussels sprouts, kale), which provide soluble and insoluble fiber, chlorophyll, B vitamins, vitamin K, and many anti-inflammatory compounds. In practice, at least half of each main meal’s plate should be reserved for vegetables—ideally raw or minimally processed (steaming, short blanching, low-temperature roasting) to reduce the loss of vitamins sensitive to heat and light. For those on weight loss meds, a large volume of vegetables with few calories helps “fill” the stomach, so a smaller portion of protein or carbs leads to better satiety—especially valuable when a medication strongly suppresses appetite and there is a risk of too little total energy and nutrients. Aim for at least 400–500g of vegetables daily, spread over 2–3 meals, ensuring diversity—the more colors throughout the day, the more complete the micronutrient intake. Raw vegetables (lettuce, cucumber, radishes, bell pepper, carrots) are great for lunch or dinner, while steamed broccoli or cauliflower are gentler on a sensitive stomach for those who quickly feel digestive discomfort after medications. To maximize their protective potential, combine vegetables with a little healthy fat—e.g., olive oil, avocado, nuts, or seeds—to improve absorption of vitamins A, D, E, and K, which may be less well-absorbed if you’re taking medications affecting fat metabolism or appetite. Vegetables also help regulate water and electrolyte balance: cucumber, celery, zucchini, or tomato provide water and potassium, helping to prevent weakness, muscle cramps, and blood pressure drops, which can sometimes accompany rapid weight loss. If you notice slower intestinal motility after starting therapy, increasing dark leafy greens (spinach, romaine, arugula), cabbages, and beets, along with proper fluid intake, can naturally support intestinal function, reducing the need for laxatives that further increase micronutrient loss.
Fresh fruits in the diet during weight loss medication therapy serve a slightly different but equally important role—they deliver vitamin C, antioxidants (flavonoids, polyphenols), potassium, and folic acid, while satisfying the craving for “something sweet” in a healthier form than cookies or candy. Due to their natural sugars (fructose), those with high insulin sensitivity or diabetes accompanying obesity should stick to 2–3 servings of fruit daily, ideally paired with protein or fat (e.g., natural yogurt, cottage cheese, a handful of nuts) to stabilize blood glucose and avoid sudden energy spikes and hunger attacks. Give priority to fruits with higher nutrient density: citrus fruits (oranges, grapefruits—ensure they do not interact with your medication—always consult your doctor!), kiwi, berries, raspberries, blueberries, strawberries, currants, plums, or apples—they’re packed with soluble fiber (pectins) and polyphenols, which support gut microbiota that may change with rapid weight loss. Adding a handful of frozen berries or raspberries to morning oatmeal, a post-workout protein shake, or natural yogurt is a simple way to boost vitamin C and antioxidants without substantially increasing meal calories. To minimize risk of deficiencies, think of vegetables and fruits on a weekly basis: plan for at least several different varieties in each group over 7 days, including green, red, orange, yellow, and purple types, as the different pigments (lycopene from tomatoes, beta-carotene from carrots and pumpkin, anthocyanins from berries and red cabbage, lutein from leafy greens) support different systems—immunity, vision, cardiovascular health, or cell protection from oxidative stress accompanying weight loss. In practice, start with simple habits: add at least one portion of vegetables to every meal (e.g., a handful of salad mix, tomato and cucumber slices for sandwiches, a bowl of steamed veg at dinner), and treat fruits as 1–2 planned snacks daily, rather than extra to already eaten sweets. This way, even with lower appetite, nausea, or quick satiety from medication, you’re more likely to consistently get all key micronutrients, building a genuinely protective diet that doesn’t just “cut” calories.
High-quality protein sources on a weight loss diet
During weight loss medication therapy, adequate protein intake becomes a key element of your menu—it not only supports fat loss, but above all protects muscle and helps maintain steady energy levels despite reduced appetite. Medications that decrease hunger or affect nutrient absorption from the digestive tract may decrease total calories eaten, and with them, protein. If there is too little protein, the body begins “snacking” on its own muscle, metabolic rate drops, you feel weak, get colder, recover worse after exertion, and risk deficiencies in iron, zinc, or B vitamins. Therefore, meals during therapy should be planned so that each dish contains a distinct, complete protein source—that is, one that provides all essential amino acids in proper proportions. For most people losing weight, 1.2–1.6 g protein per kg of body weight per day is recommended (sometimes more for very active individuals); with weight loss medications, this range is particularly beneficial as it increases satiety, improves appetite control, and stabilizes blood glucose. In practice, build most of your plate “around protein”—then add vegetables, healthy fats, and complex carbs, remembering that it’s not just about the quantity, but also the quality and diversity of sources.
The simplest way to deliver complete protein is to reach for lean animal products with high amino acid bioavailability: poultry (chicken breast, turkey, turkey loin), lean beef, veal, rabbit, as well as fish and seafood. Opt for fatty sea fish (salmon, mackerel, herring, sardines) more often, as they also provide beneficial omega-3 fatty acids, which have anti-inflammatory effects and may ease some unpleasant side effects of rapid weight loss, such as low mood or concentration problems. A good strategy is to plan at least 2–3 fish meals per week, alternating on other days between poultry, lean pork (e.g., loin, tenderloin), and low-fat beef. For those on meds affecting fat digestion, leaner meat cuts and preparing them by boiling, stewing, or baking without breading helps the digestive tract stay less burdened while keeping high protein density in the portion. Another group is eggs, a model example of complete protein—they also deliver iron, vitamins A, D, E, K, and choline (important for liver and brain function). For most people, 1–2 eggs daily in a weight-loss diet is a safe amount, especially when the rest of the menu is based on vegetables, wholegrains, and unsaturated fats. Dairy also plays an important role: Greek yogurt, skyr, cottage cheese, kefir, buttermilk, or semi-fat cheeses. High-protein natural versions without added sugar are ideal for breakfasts, dinners, or snacks on days when, due to medication, it is difficult to eat a larger, solid meal—thick yogurt with nuts, chia, and fruit “slips in” easily even with low appetite, and delivers a solid dose of protein, calcium, and probiotics supporting gut microbiota.
Complete protein can also come from plant foods, especially for vegetarians or those limiting meat during therapy. Single plant sources (e.g., just beans or just grains) usually lack ideal amino acid proportions, but when combined throughout the day, they can give a full profile—“complementary protein.” In practice, dishes such as hummus with wholemeal bread, chili sin carne with beans and brown rice, lentils with buckwheat, or tofu with quinoa meet the body’s needs as effectively as animal protein. Soy and soy products (tofu, tempeh, calcium-fortified soy drink) are close in protein quality to animal products, so feature them a few times a week; paired with leafy veg and healthy fats, they create a filling yet relatively light meal, crucial when eating volume is restricted. For people taking GLP-1 medications, a typical issue is feeling full quickly and discomfort after large meals—here, smaller protein portions evenly distributed over 4–5 smaller meals a day work better than two large ones. Opt for high-protein snacks: a shake based on yogurt and protein powder, a handful of roasted chickpeas, a mini salad with tuna or tofu, or turkey roll-ups with cottage cheese. Such solutions reduce protein deficiency risk with limited calories, help stabilize blood sugar, and support the preservation of muscle mass, which is a key ally in maintaining the effects of weight loss medication therapy.
The importance of healthy fats
Healthy fats often get unfairly sidelined during weight loss medication therapy, as many still equate “weight loss” with a fat-free diet. However, with medications that decrease appetite, speed intestinal transit, or affect nutrient absorption, the right amount of good quality fat is a crucial element in protecting against deficiencies. Fats enable absorption of fat-soluble vitamins (A, D, E, K), which are responsible for immunity, bone health, skin and eye condition, and normal blood clotting. Too little fat in the diet, especially while taking appetite-suppressing meds or those reducing fat absorption, greatly increases the risk of deficiencies of these vitamins. The body also needs fats for building cell membranes, making hormones (including sex hormones), and regulating inflammation—especially important when under stress from weight loss and changing eating habits. Well-chosen fats in a meal extend satiety, stabilize blood glucose, and reduce the risk of sudden hunger attacks, which helps you better align with the medication’s effect and avoid rebound overeating. Keep in mind that fat is very calorie-dense, so during weight loss therapy, it’s not about quantity, but quality and smart portions—usually 25–35% of daily energy from fat is enough, which, in practice, is a carefully chosen small amount with each meal. Above all, poly- and monounsaturated fatty acids, especially omega-3 and omega-6, are essential as the body can’t synthesize them and they must be obtained from food. Omega-3s are anti-inflammatory, support brain and nervous system function, and during weight loss may ease mood swings and give mental comfort. In practice, add fatty sea fish (salmon, mackerel, herring, sardines), flaxseeds, chia seeds, or walnuts to your menu regularly. Plant oils high in monounsaturates—such as extra virgin olive oil or canola oil—support heart health and a healthy lipid profile, which is important as some weight loss medications are used in people with metabolic issues (insulin resistance, metabolic syndrome, or high cholesterol). It’s also worth using whole-food sources of fat, not just oils —avocado, nuts, seeds, and oily fish, provide protein, fiber, vitamins (esp. E as a strong antioxidant), and minerals like magnesium, zinc, and selenium, which help reduce fatigue and lower immunity during intense reduction.
While on weight loss medication therapy, plan healthy fat presence in each meal consciously and adjust quantities to individual digestive tolerance and the mechanism of the medication. If you’re taking meds that limit fat absorption in the gut (e.g., containing orlistat), excess fat in one meal can cause unpleasant digestive issues (diarrhea, fatty stools, bloating), so it is beneficial to spread small portions of fat evenly throughout the day and avoid heavy, fried foods. Here especially, every portion of fat should be “nutrient-dense”: better to drizzle vegetables with a spoon of olive oil, add a handful of pumpkin seeds to soup, or have a small portion of nuts, than to reach for saturated fats from fast foods, bakery goods, or processed meats. Saturated fats (from large amounts of fatty red meat, lard, excessive butter, processed sausages, crisps, or confectionery with palm fat) don’t help prevent deficiencies and may worsen inflammation, burden the liver, and harm lipid profiles, ultimately reducing the long-term health benefits of weight loss. Those on appetite-altering meds (e.g., GLP-1 analogs, which slow gastric emptying) may feel quick fullness, nausea, or bloating—so introduce fats in small amounts, adding them to light meals, e.g., a teaspoon of olive oil over vegetables, thin avocado slices on wholegrain bread, or a handful of nuts in a protein-rich yogurt. This way, your body receives fat needed for vitamin absorption, but your stomach is not overburdened. Remember also the role of fat in stabilizing blood sugar: combining protein, fiber, and healthy fats in meals (e.g., salad of leafy vegetables, grilled chicken, olive oil, nuts, and a portion of groats) limits glucose and insulin spikes, which trigger hunger attacks, and in insulin resistance or diabetes lower the risk of uncontrolled snacking despite medication. Even if your appetite is very low, don’t eliminate fat entirely—it’s better to eat a smaller volume meal but include quality fats, than to focus on very “lean” but also poorly nourishing products. This way, every bite is maximally nourishing, and the risk of deficiencies in fat-soluble vitamins, fatty acids, and related problems (dry skin, low mood, lower immunity, concentration issues) is clearly reduced, even though total calorie intake is minimized by the medication and calorie restriction.
Avoiding empty calories and processed foods
During weight loss medication therapy, the body usually receives less energy and appetite is significantly reduced, so every bite has a much greater “nutritional significance” than during normal eating. Empty calories—foods that deliver mostly sugar, refined carbs, and unhealthy fats with minimal vitamins, minerals, and fiber—are particularly harmful in this context. They take up stomach space, bring fleeting pleasure, but provide no building blocks or tissue protection. That is an easy way to hit your daily calorie limit with low-value foods, and then suffer fatigue, infection susceptibility, poorer hair, skin, and nails, or concentration issues. This is especially true for those who turn to appetite suppressants or gastric-emptying medications—it’s easier to “fill up” on chips than eat a wholesome meal. Typical sources of empty calories that you should avoid or limit to an absolute minimum are sweets (candy bars, filled chocolates, cookies, pastries, candies), white bread and refined flour products, sweetened breakfast cereals, sweet yogurts and dairy desserts, as well as drinks like cola, sweetened “juices,” and energy drinks. While these foods seem to improve mood, their abrupt effect on blood glucose leads to later energy crashes, hunger attacks, and uncontrolled snacking—which can undermine therapy effects and discourage ongoing weight management. From a deficiency prevention perspective, every meal high in sugar or white flour pushes vegetables, whole grains, protein foods, or healthy fats off your plate. If due to medication your eating capacity is low, then eating a donut “instead of lunch” means you get virtually no magnesium, zinc, iron, B vitamins, or antioxidants—needed to maintain metabolic rate and help the body recover during weight loss. Be wary of salty snacks as well—chips, pretzels, crackers, salted roasted nuts, or microwaved popcorn offer lots of salt and trans fats with barely any beneficial nutrients, and may promote water retention, bloating, and a heavy feeling. Many people on weight loss drugs also struggle to control “convenience foods”—ready-to-heat meals (pizzas, lasagna, burgers, breaded cutlets, supermarket fries or dumplings) often contain high calories, unhealthy fats, salt, and taste enhancers at once. With reduced appetite, they’re easy to “fill up on” without supplying valuable micronutrients. Instead, choose simple, unprocessed staples quickly combined into a wholesome meal, e.g., cooked or baked meat or fish, groats, brown rice, fresh or frozen vegetables, and plain dairy. Even if you do occasionally have a processed product, check the label—the shorter the ingredients list, with no glucose-fructose syrup, hydrogenated vegetable fats, or excess salt, the better for your health and nutrition balance.
Avoiding empty calories during weight loss medication therapy doesn’t mean giving up convenience or enjoyment, but consciously replacing highly processed foods with nutrient-dense ones. Practical strategies include planning meals ahead, batch cooking healthy dishes and freezing portions, keeping low-processed food staples (eggs, natural yogurt, cottage cheese, frozen veg, groats, wholegrain bread, canned chickpeas or beans with no added sugar) at home, and avoiding shopping while hungry, when it’s easy to grab sweets or salty snacks. Learning to read nutrition labels is also key—when you can’t avoid a processed product (e.g., bread, cold cuts, flavored dairy), check sugar content, type of fat, salt quantity, and for glucose-fructose syrup, maltodextrin, hydrogenated oils, or excessive colors and flavors. During a weight loss diet, opt for “light” or natural versions only if they truly have less sugar and aren’t compensated with artificial sweeteners at levels that can trigger gastrointestinal problems—people using medications are sometimes more sensitive to this. Work out permanent swaps in your daily menu—choose fruit with protein (e.g., an apple with nuts, yogurt with berries) instead of sweets; water with lemon, herbal teas, or unsweetened fruit infusions instead of sweet drinks; and wholegrain or sourdough rye bread instead of white bread. For those who habitually snack on sweets in the evenings, pre-prepare “healthy snacks”: sliced veg with hummus, a handful of unsalted nuts, natural kefir, or seasonal fruit—so that if you need a quick bite, you reach for something actually benefitting your body. To avoid deficiencies during weight loss medication therapy, ensure that every meal—even a small one—contains at least one food from each group: high-quality protein (eggs, dairy, legumes, lean meat or fish), vegetables and fruits, whole grains, and healthy fats (e.g., olive oil, avocado, unsalted nuts). Such a “meal matrix” helps intuitively eliminate empty calories—it’s hard to manage a candy bar when the portion is limited by the medication and you consciously care about having these four pillars present. As a result, every meal is a concentrated dose of nutrients supporting metabolism, the nervous and immune systems, and recovery during weight loss, minimizing deficiency risks despite reduced calorie intake.
The role of hydration and supplementation in the weight loss process
Hydration during weight loss medication therapy means much more than simply “quenching thirst.” Some drugs affect appetite, gastric emptying speed, or fat absorption, which also changes how your body manages water and electrolytes. Too little fluid intake can exacerbate typical side effects—headaches, dizziness, constipation, tiredness, heart palpitations, or even fainting. In practice, you should aim for about 30–35 ml of fluid per kg of body weight per day during therapy (unless otherwise instructed by your doctor for kidney, heart, or hypertension conditions), remembering that for some people, weight loss meds weaken thirst so you can’t rely only on “instinctive” drinking. The basis should be water—still or slightly sparkling—supplemented with unsweetened herbal infusions (mint, lemon balm, chamomile), green or white tea, and light vegetable broths, which also provide sodium and potassium. Limit caffeinated drinks to 2–3 servings a day, as excess can increase urination and heart palpitations, especially in people also taking blood pressure or diabetes medications. Avoid sweetened drinks, “diet” juices, or energy beverages—even if they fit your calorie limit, they affect blood glucose and worsen appetite swings. If your medication causes nausea or vomiting, hydration is especially important: in these cases, drink small amounts more often (sips every few minutes) rather than downing a big glass at once; slightly chilled drinks or water with a slice of lemon or cucumber can also help. Another issue is electrolyte balance—heavy sweating, diarrhea, or vomiting during medication can lead to loss of sodium, potassium, magnesium, and chloride. In such cases, after consulting with a doctor or dietitian, sugar-free isotonics or powdered electrolytes may help, but avoid random products containing large amounts of sugar or caffeine. Importantly, water alone cannot replace adequate mineral intake from your diet—green leafy vegetables, tomatoes, potatoes, legumes, nuts, and seeds should support water-electrolyte balance daily. Watch your urine color—too dark usually signals insufficient hydration—and how you feel after meals: worsening headaches, fatigue, or muscle cramps may indicate both a lack of fluids and deficiencies in potassium or magnesium. Also, drinking too much water without salting foods or providing electrolyte sources can lead to hyponatremia (low sodium), which shows up as drowsiness, nausea, and trouble concentrating. Plan hydration consciously: distribute drinking throughout the day, always have a bottle of water handy, and with more physical exertion or heat, choose medium- or high-mineral content water.
Weight loss medication therapy also increases the risk of vitamin and mineral deficiencies, so well-planned supplementation may be important for health protection, but only as an addition to a well-composed diet. Some drugs cut the amount of food due to lower appetite; others decrease intestinal fat absorption. The latter especially favors deficiencies in fat-soluble vitamins: A, D, E, and K. People on fat absorption-disrupting meds often need extra from supplements—always in doses and forms recommended by a doctor, and for vitamin D after checking your blood’s 25(OH)D level. Low intake of these vitamins can show as reduced immunity, dry skin, vision problems at night, gum bleeding, or slow wound healing. B vitamins (particularly B1, B6, B12, and folic acid) are also crucial for energy metabolism and nervous system function—low-calorie diets lacking whole grains, meat, or dairy can cause chronic fatigue, irritability, and concentration issues. In such situations, a quality B vitamin complex, used as directed, may help. Deficiencies in iron (in menstruating women or those on plant-based diets), calcium (if dairy is low), and magnesium (with high stress, diarrhea, or some diuretics) are also often problematic. Before using a commercial “multivitamin,” do basic blood tests (CBC, ferritin, iron, vitamin D, B12, and sometimes folic acid) and consult a doctor or clinical dietitian—too much iron or vitamin A can be as dangerous as too little. Note the risk of interactions: some supplements (large fiber doses, calcium, iron) may reduce the absorption of oral medications, so usually a 2–3 hour gap is advised between the weight loss drug and supplement. Make sure your vitamin-mineral supplements use gut-friendly forms (e.g., magnesium citrate over oxide, methylcobalamin over cyanocobalamin for methylation issues), and avoid “weight loss” supplements that promise fat burning, faster metabolism, or strong appetite suppression—their combination with doctor-prescribed drugs can worsen side effects, affect blood pressure, heart function, or glucose control. Safer is to focus on a few key, individually matched supplements—usually vitamin D (often with K2), omega-3 (if little fish intake), magnesium, possibly B vitamins and iron—and get “the rest” from a diverse, nutrient-dense diet. Only this approach actually reduces deficiency risk during weight loss medication therapy, instead of covering up the problem with more pills.
Summary
During weight loss medication therapy, maintaining a balanced diet is crucial to avoid deficiencies. The menu should include a variety of vegetables and fruits to provide the body with vitamins and minerals. Choosing the right protein sources, such as lean meats and legumes, will help maintain muscle mass. Avoiding processed foods and empty calories is key to effective weight loss. Remember about healthy fats, regular hydration, and, if necessary, appropriate supplementation. Only in this way can you support a healthy weight loss process.
