If you’re taking a GLP-1 medication like Semaglutide or Tirzepatide, what you eat can make a big difference.These powerful weight loss tools help regulate appetite and blood sugar—but pairing them with the right foods can enhance your results, reduce side effects, and support long-term success.

Whether you’re just starting your journey or looking to fine-tune your nutrition, this guide breaks down the best foods to eat, what to avoid, and how to build a sustainable routine while on GLP-1s.

Why Diet Matters on GLP-1s

Semaglutide (commonly known by names like Ozempic® and Wegovy®) and Tirzepatide (like Mounjaro® and Zepbound™) work by mimicking natural gut hormones that slow digestion and reduce hunger. This can lead to:

• Reduced appetite
• Early fullness
• Slower gastric emptying
  

But that also means your food choices matter more. Eating large, greasy, or sugary meals can increase nausea, bloating, and fatigue. On the flip side, choosing gentle, nutrient-rich foods can support your body’s energy and make your medication easier to tolerate.

GLP-1 Friendly Foods to Prioritize

Here’s what your plate should focus on while taking Semaglutide or Tirzepatide:

1. Lean Protein (the most important!)

Protein helps preserve lean muscle mass during weight loss and keeps you fuller for longer.

‍

‍Try:

• Eggs or egg whites
• Chicken, turkey, fish
• Greek yogurt or cottage cheese
• Tofu or tempeh
• Protein shakes (look for low-sugar options)
  

Pro Tip: Aim for 80–100g of protein per day depending on your body size and goals.

2. Fiber-Rich Vegetables and Low-Glycemic Carbs

Fiber keeps digestion moving and helps prevent constipation—a common side effect of GLP-1s.

‍

‍Try:

• Leafy greens, broccoli, zucchini, bell peppers
• Quinoa, oats, sweet potatoes, beans
• Berries and apples in moderation

3. Healthy Fats (in moderation)

Fat supports hormone health and keeps meals satisfying—but too much can slow digestion too much.

‍

‍Try:

• Avocados
• Olive oil
• Chia or flax seeds
• A handful of nuts

4. Hydrating, Low-Sugar Drinks

Many people on GLP-1s experience dry mouth or dehydration. Staying hydrated helps regulate digestion and energy.

‍

‍Try:

• Water
• Herbal teas
• Coconut water (unsweetened)
• HydroBelle hydration sticks for an easy, on-the-go electrolyte boost

Sample Day of Eating on a GLP-1

• Breakfast:
  
  • Scrambled eggs with spinach + half an avocado
  • HydroBelle electrolyte water
    
• Lunch:
  
  • Grilled chicken bowl with quinoa, roasted veggies, and tahini drizzle
• Snack:
  
  • Protein shake or Greek yogurt with chia seeds
• Dinner:
  
  • Baked salmon with sweet potato and steamed broccoli
• Optional Snack:
  
  • Cottage cheese with cucumber slices or berries
    

Foods to Limit (or Avoid)

Some foods can worsen GLP-1 side effects or interfere with weight loss:

• High-fat fried foods (can cause nausea or indigestion)
• Sugary desserts (spike blood sugar and worsen fatigue)
• Carbonated beverages (can cause bloating and gas)
• Alcohol (can intensify nausea or dizziness)

Other Tips for Eating on GLP-1s

• Eat slowly. Overeating can happen quickly because fullness sets in after the fact.
• Small portions. You’ll likely need less food than you’re used to.
• Stay consistent. Skipping meals can lead to blood sugar crashes or fatigue.
• Listen to your body. Your appetite will change—honor it, but fuel it wisely.
