Are you taking GLP-1 medications like Wegovy or Zepbound and worried about nutrient deficiencies? Here's the deal: Yes, these weight loss drugs can lead to deficiencies, but the good news is you can easily prevent them! I've worked with dozens of clients on these medications, and the key is being proactive about your nutrition.
The truth is, when you're eating significantly less food, your body gets fewer vitamins and minerals. That's why we need to focus on nutrient-dense foods and sometimes supplements. In this guide, I'll show you exactly which nutrients are at risk and simple ways to keep your levels optimal while still losing weight effectively.

5 Nutrient Deficiencies You Might Face on Wegovy & Zepbound
Let me tell you something funny - these weight loss drugs work so well that sometimes they make you forget to eat! But here's the serious part: when you're eating less, you might miss out on key nutrients. I've seen this happen to many of my clients, and today I'll walk you through exactly what to watch for.
Why These Drugs Affect Your Nutrition
GLP-1 medications like Wegovy and Zepbound are amazing tools, but they come with a catch. They slow down your digestion so much that you might only eat half of what you used to. That's great for weight loss, but terrible for nutrient intake if you're not careful.
Think about it this way - if you normally eat 2000 calories packed with vitamins, and suddenly you're only eating 1200 calories, you're getting 40% less of everything! That's why we need to be smart about food choices.
The Big 5 Nutrients You Can't Afford to Miss
Protein: Your Body's Building Blocks
Protein isn't just for bodybuilders - it's what keeps your hair shiny, your skin healthy, and your muscles strong. When clients come to me complaining about hair loss on these medications, protein is always the first thing we check.
Here's a quick comparison of protein sources:
| Food | Protein (g) | Calories |
|---|---|---|
| Chicken breast (3oz) | 26 | 140 |
| Greek yogurt (1 cup) | 17 | 100 |
| Eggs (2 large) | 12 | 140 |
Did you know your body can't store protein like it stores fat? That's why you need to eat some every single day. I recommend spreading it out - maybe some eggs at breakfast, yogurt at lunch, and chicken at dinner.

Vitamin D: The Sunshine Vitamin
Here's a question that might surprise you: Why do so many people feel tired in winter? It's often because they're not getting enough vitamin D! This nutrient does way more than just help your bones - it boosts your mood and immune system too.
On these medications, you might not be eating enough fatty fish or dairy to get your vitamin D. I've had clients who started taking supplements and suddenly had way more energy. Just last week, Sarah told me, "I feel like a different person since I started my vitamin D!"
Calcium & Iron: The Dynamic Duo
Calcium Isn't Just for Kids
Remember when your mom told you to drink milk for strong bones? She was right! But calcium does more than that - it helps your muscles move and your nerves send messages. If you're cutting out dairy to lose weight, you need to find other sources.
Try this trick I give my clients: add a handful of kale to your smoothie or snack on almonds. Both are great non-dairy calcium sources. One of my clients, Mike, actually prefers almond milk now - he says it makes his coffee taste better!
Iron: Your Energy Booster
Ever feel like you're dragging through the day no matter how much sleep you get? That could be low iron. Here's another question: Why do women need more iron than men? It's because we lose iron during our periods each month.
The coolest trick I've found? Pair iron-rich foods with vitamin C. Try spinach with strawberries or lentils with bell peppers. The vitamin C helps your body absorb the iron better. My client Jessica swears by her "power salad" - spinach, chickpeas, and orange slices.
Vitamin B12: The Silent Deficiency
B12 is sneaky - you might not notice you're low until you're really deficient. I've seen clients come in with tingling hands or trouble concentrating, and B12 is often the culprit. If you're eating less meat or dairy, you need to be extra careful.
Here's a pro tip: nutritional yeast is a vegan's best friend for B12. Sprinkle it on popcorn or pasta - it tastes cheesy but is packed with nutrients. One of my vegetarian clients calls it "magic fairy dust" because it makes everything taste better!
Simple Strategies to Stay Nourished

Vitamin D: The Sunshine Vitamin
When you're eating less, every bite needs to work harder. I tell my clients to think of their stomach like a tiny apartment - you only have so much space, so fill it with good stuff!
Try these easy swaps:- Instead of plain rice, try quinoa (more protein)- Swap iceberg lettuce for spinach (more nutrients)- Choose Greek yogurt over regular (more protein)
Smart Supplementation
Sometimes food alone isn't enough, and that's okay! A good multivitamin can fill in the gaps. But here's the thing - not all vitamins are created equal. Look for ones that say "complete" or "high potency."
I always remind my clients: supplements are like seatbelts - they're there for protection, but you still need to drive carefully (aka eat well)!
Listen to Your Body
Your body is smarter than you think. If you're feeling extra tired, craving ice (yes, that's a real sign of iron deficiency!), or noticing hair loss, don't ignore it. Those are your body's way of saying "Hey, I need help here!"
One client, David, thought his fatigue was just from work stress. Turns out he was low in both iron and B12. After fixing that, he said he felt "like a teenager again" - and his wife agreed!
Final Thoughts
Losing weight is great, but not at the cost of your health. With these simple tips, you can enjoy the benefits of Wegovy or Zepbound without the nutrient pitfalls. Remember - your body deserves the best fuel, especially when you're asking it to change!
What's the first nutrient you're going to focus on? Maybe start with protein - it's the easiest to track and makes the biggest difference in how you feel. Trust me, your future self will thank you!
The Hidden Impact on Gut Health

Vitamin D: The Sunshine Vitamin
Here's something wild - did you know your gut contains about 40 trillion bacteria? That's more than all the stars in the Milky Way! When you're on weight loss medications that slow digestion, you're not just affecting what you eat, but also those hardworking little gut buddies.
I had a client, Emily, who complained about constant bloating after starting Wegovy. Turns out, her sudden drop in fiber intake was starving her good gut bacteria. We fixed it by adding just one tablespoon of ground flaxseed to her morning smoothie - problem solved!
Fiber: The Forgotten Hero
Why does everyone forget about fiber until they're backed up? It's like ignoring the plumbing in your house until the toilet overflows! On these medications, you need fiber more than ever because slower digestion can lead to... well, let's just say uncomfortable situations.
Here's my favorite fiber hack: chia pudding. Mix 2 tablespoons chia seeds with half cup almond milk, let it sit overnight, and boom - you've got a gut-friendly breakfast. Plus it looks like frog eggs, which always makes me laugh!
The Emotional Eating Transition
Breaking Up With Comfort Food
This might hit close to home for some of you - what happens when your favorite emotional crutch (hello, mac and cheese!) suddenly doesn't appeal anymore? For many of my clients, this is actually the hardest part of medication-assisted weight loss.
Just last month, my client Mark teared up telling me, "I miss enjoying pizza with my kids on Friday nights." We worked together to find new traditions - now they make homemade veggie-packed flatbreads together. The bonus? His kids are eating healthier too!
Rediscovering Joy in Eating
When food becomes purely functional, we lose something important. I always tell my clients - food should still bring pleasure, even when you're eating less. It's about quality over quantity.
Try this experiment: next meal, turn off all screens, set the table nicely, and really taste each bite. My client Sarah said this simple practice made her feel more satisfied with smaller portions. "I finally understand what mindful eating means," she told me.
The Social Side of Eating Less
Navigating Dinner Parties and Holidays
Ever been to a family gathering where Aunt Karen insists you "eat more, you're too skinny!" even though you're actively trying to lose weight? Yeah, me too. Social situations can be tricky when your appetite changes.
Here's my go-to strategy: focus on the people, not the plate. At events, I'll put tiny portions of everything on my plate, then spend most time chatting. No one notices how little you're eating if you're the life of the conversation!
Restaurant Survival Guide
Did you know most restaurant portions are 2-3 times what we actually need? When dining out on these meds, I teach clients the "rule of thirds": eat 1/3 of the entrée, take 1/3 home, and share 1/3 with your dining companion.
Pro tip: ask for a to-go box when you order. That way, you can pack up half before you even start eating. My client James does this religiously - he's lost weight while still enjoying his favorite steakhouse!
Hydration: The Secret Weapon
Water Does More Than You Think
Here's a fun fact that'll blow your mind - sometimes when you think you're hungry, you're actually thirsty! On these medications, staying hydrated becomes even more crucial because slower digestion can lead to dehydration.
I challenge my clients to try the "water first" rule: drink a full glass before every meal. Not only does it help with hydration, but it also prevents overeating. Client Maria reported she naturally eats 20% less when she follows this simple step!
Electrolytes: Not Just for Athletes
Why do you think pickle juice helps with hangovers? Electrolytes, baby! When you're eating less, you might not be getting enough sodium, potassium and magnesium from food.
My favorite electrolyte booster: coconut water with a pinch of sea salt. It's nature's sports drink! Client Tom, a retired firefighter, swears by this after his morning walks. "Tastes better than those neon sports drinks," he says, "and no weird chemicals!"
Sleep and Weight Loss Connection
The Midnight Munchies Mystery
Ever notice how everything looks delicious when you're tired? There's science behind that! Poor sleep messes with your hunger hormones, which can work against your weight loss efforts.
Here's a counterintuitive tip: if you're struggling with nighttime cravings, try going to bed earlier. Client Lisa found that by moving her bedtime up just 30 minutes, she stopped raiding the fridge at 11pm. "Best weight loss hack ever," she claims!
Medication Timing and Sleep Quality
Some people find their GLP-1 medications affect their sleep. If that's you, try this: track your injection times and sleep patterns for a week. You might discover that taking your shot in the morning instead of evening makes a difference.
My client Robert, a night shift nurse, had terrible insomnia until we adjusted his injection schedule. Now he sleeps like a baby (during the day, in his case) and has more energy for his shifts!

FAQs
Q: Can Wegovy really cause vitamin deficiencies?
A: Absolutely! Here's what I tell my clients: Wegovy and similar GLP-1 drugs work by making you feel full faster and longer, which naturally leads to eating less. The problem? When you cut calories, you often cut nutrients too. The most common deficiencies I see are protein, vitamin D, calcium, iron, and B12. The solution isn't eating more - it's eating smarter. Focus on packing those smaller meals with high-quality nutrients, and consider a good multivitamin if your doctor agrees.
Q: How much protein should I eat on Zepbound?
A: Great question! While the standard recommendation is about 50g daily, my clients on Zepbound typically need more - around 60-75 grams per day. Here's why: Protein helps maintain muscle mass during weight loss and keeps your hair, skin, and nails healthy. I suggest spreading it throughout the day - maybe Greek yogurt at breakfast, chicken at lunch, and fish at dinner. Pro tip: Keep some hard-boiled eggs or cottage cheese handy for quick protein boosts when you're not hungry for a big meal.
Q: What are signs of vitamin D deficiency on weight loss drugs?
A: Watch for these red flags I often see in my practice: unusual fatigue, muscle weakness, bone pain, or even mood changes. Vitamin D is crucial for bone health and immune function, and it's harder to get enough when you're eating less dairy and fatty fish. Many of my clients are surprised when their bloodwork shows low levels. The fix? Try vitamin D-rich foods like salmon and eggs, get some safe sun exposure, and ask your doctor about testing your levels.
Q: Should I take iron supplements on Wegovy?
A: Maybe, but let's be careful here. While iron deficiency is common (especially in women), too much iron can be harmful. First, look for these symptoms I frequently encounter: extreme tiredness, pale skin, or strange cravings like wanting to chew ice. Before taking supplements, try iron-rich foods like lean meats, lentils, and spinach - and pair them with vitamin C foods to boost absorption. If symptoms persist, your doctor can check your levels and recommend the right supplement if needed.
Q: How can vegans avoid B12 deficiency on GLP-1 drugs?
A: As someone who works with many plant-based clients, this is super important! B12 only comes from animal products naturally, so vegans are at higher risk - especially when eating less. My go-to solutions: fortified nutritional yeast (my clients love it on popcorn!), B12-fortified plant milks, or a sublingual B12 supplement. Watch for tingling hands or brain fog - classic signs I've seen in deficient clients. The good news? A little planning keeps your B12 levels perfect while still enjoying your vegan lifestyle.
