Nutrition on GLP-1: Lagos Meal Plans & Macro Strategy

Published January 11, 2026 | Nutrition Guide | 10 min read

GLP-1 changes your appetite. Your nutrition strategy must change too. This guide shows how to eat for maximum weight loss while preserving muscle on Semaglutide or Tirzepatide.

The Macro Reality on GLP-1

Your calorie intake will naturally drop 40-60% due to appetite suppression. That's good. But protein demands INCREASE to preserve muscle during weight loss.

Why Protein Matters More

Target Macro Breakdown

For 70kg Person

Protein
120-140g daily (1.7-2g per kg bodyweight)
Fat
40-60g daily (don't go too low, hormone production needs it)
Carbohydrates
80-120g daily (fill with fiber, lower glycemic)
Daily Calories
1,400-1,800 kcal (hunger naturally limits intake)

Adjust these based on your starting weight: heavier = slightly higher protein targets

Lagos Protein Sources (High Priority)

Getting 120g protein daily is the challenge. Here are practical Lagos options:

Animal Proteins (Highest Quality)

PER 100G
Chicken Breast (Boiled)

31g protein | 165 kcal

Most efficient protein source. Buy at Justrite/Shoprite, boil plain. Boring but most satiating.

PER 100G
Eggs (Large, Boiled)

13g protein (2 eggs) | 155 kcal

Reliable, accessible protein. Eat whole egg (yolk has nutrients GLP-1 users need)

PER 100G
Fish (Canned Mackerel/Sardines)

20g protein | 180 kcal

Omega-3 rich. Buy tinned at Lagos supermarkets. Eat with minimal oil added.

PER 100G
Beef/Goat Meat (Lean)

26g protein | 200 kcal

Ask butcher for lean cuts (suya meat is fatty). Grilled or boiled preferred.

Plant Proteins (Everyday staples)

PER 100G
Beans (Black-Eyed Peas, Cooked)

9g protein | 120 kcal

Nigerian staple. High fiber (good for GLP-1 users). Can cause bloating - introduce slowly.

PER 100G
Lentils (Cooked)

9g protein | 110 kcal

High fiber, high protein plant source. Less gas than beans.

PER SERVING
Greek Yogurt (Plain, Unsweetened)

20g protein/200g | 130 kcal

Probiotics good for GLP-1 users. Get Activia/plain Greek yogurt at Justrite.

Protein Powder (Time-Saver)

Whey protein powder: 25g protein per scoop. Mix with water or unsweetened almond milk. Makes hitting 120g protein much easier.

Recommended daily protein spread: 30g breakfast, 40g lunch, 40g dinner = 110g. + 10g snack = 120g target

Sample Lagos Day Eating Plan

1,500 kcal | 120g protein | GLP-1 friendly

Breakfast (7am)
2 Boiled Eggs + 1 Slice Whole Wheat Bread
26g protein | 300 kcal
Mid-Morning Snack (10am)
Greek Yogurt (200g) + Berries
20g protein | 180 kcal
Lunch (1pm)
150g Grilled Chicken + Steamed Broccoli + 100g Brown Rice
45g protein | 420 kcal
Afternoon Snack (4pm)
Protein Shake (25g protein powder + water)
25g protein | 120 kcal
Dinner (7pm)
150g Lean Fish + Vegetables (Carrots, Spinach) + 50g Sweet Potato
30g protein | 320 kcal

Daily totals: 146g protein | 1,320 kcal

Foods to EMPHASIZE on GLP-1

High-Protein, High-Fiber Foods

Why: Protein preserves muscle, fiber prevents constipation (major GLP-1 side effect)

  • Chicken, fish, lean beef (all cuts)
  • Eggs (whole eggs)
  • Lentils, chickpeas, beans
  • Vegetables (especially leafy greens, broccoli, carrots)
  • Whole grains (brown rice, oats, whole wheat bread)
  • Avocado, nuts, seeds (good fats)

Foods to AVOID on GLP-1

High-Sugar, High-Fat Junk Foods

Why: Cause GI distress, nausea, offset weight loss, trigger hunger

  • Sugary drinks, soda, juice
  • Fried foods (suya, fried chicken, pastries)
  • Processed junk (biscuits, cakes, sweets)
  • Fatty meats (pork belly, beef fat)
  • Heavy sauces (mayo-heavy, creamy dressings)
  • Ultra-processed snacks (crisps, instant noodles)

GLP-1 Eating Challenges & Solutions

Challenge: Can't Finish Meals

Solution: Eat 4-5 smaller meals instead of 3. Instead of 400g chicken/rice, do 150g + snack + another meal = more protein throughout day, naturally matches appetite.

Challenge: Protein Boring / Repetitive

Solution: Rotate proteins. Monday: chicken. Tuesday: fish. Wednesday: eggs. Thursday: beef. Friday: beans + rice. Variety keeps sustainable.

Challenge: Protein Powder Expensive

Solution: Use eggs + beans + yogurt as base. Powder optional, not mandatory. 3 eggs + 1 cup beans + yogurt = 80g protein no powder needed.

Challenge: GI Distress from High Fiber

Solution: Increase fiber gradually. Week 1: 10g. Week 2: 15g. Week 3: 20g+. Body adapts. Drink more water alongside fiber.

Hydration on GLP-1 (Critical)

Appetite suppression makes you forget to drink. But you need MORE water:

Alcohol on GLP-1 (Be Cautious)

GLP-1 + alcohol = increased intoxication. Appetite suppression + alcohol = nausea. Evidence shows:

Eating Out (Lagos Restaurants)

Challenge: Most Nigerian restaurants serve large portions + fried foods

Strategy:

Meal Prep Strategy

Sunday meal prep: Cook weekly proteins in bulk

This takes 2 hours. Gives you 5-7 days of ready meals. Most people lose consistency when they don't meal prep.
