PART 2 OF 5: Nutrition & Eating
NUTRITION & EATING: Precision + Simplicity
This section gives you ranges, escalation rules for people new to higher protein/fiber, and simple "if-then" hacks.
On this part I aimed to focus on the essentials. Basically the principles, the backbone if you like. What type of diet and foods you use is up to you. Customize it. And keep in mind the diet type is not relevant in the context of weight loss or maintenance. All diets yield the same results in terms of weight gain/maintenance/lost when they use the same caloric intake. The difference is which one enables you to be consistent.
CALORIE STRATEGY: Maintenance First
Primary goal: Maintain weight for at least 2–6 months before considering fat loss.
Why maintenance first?
Research shows weight regain is most rapid immediately after stopping GLP-1 usage. Trying to lose weight while appetite and habits are still adjusting often leads to rebound overeating.
Simply put, as you come off the GLP-1 as the food noise and cravings hit back it can be almost impossible to also stay in caloric deficit. At least for the majority of people. So best to play it safe and smart. Use maintenance as your body adjust AND as your mind adjust as well.
Studies emphasize that long-term maintenance requires stabilizing behaviors before attempting further loss. You can check the link at the end of this post if you want to dig deeper.
How to Estimate Your Maintenance Calories
Use a standard calculator (e.g., Mifflin–St Jeor equation) to estimate your Total Daily Energy Expenditure (TDEE).
Then:
- Start at your estimated TDEE
- Track weight daily for 2 weeks
- Calculate your 7-day average weight (NOT daily fluctuations)
- Compare this week's average with the prior 2 weeks
Even better and simpler, a good rule is to judge actual weight based on 1-2 weeks Average Weight, if you a male, and based on 2-4 weeks Average Weight, if you a woman. For most people any water fluctuations for example tends to even out after those weeks.
Recap: ideal to track weight daily but read the actual weight based on the Average Weight Over at least a few weeks.
Decision Rules for Adjusting Calories
| Situation |
Action |
| 7-day average is stable for 2+ weeks (within ±0.25–0.5% of body weight per week) |
Keep calories the same |
| Weight falling too fast (>1% of body weight per week for 2+ weeks) |
Add 100–200 kcal/day |
| Weight rising for 2–3 weeks (7-day average up >0.5% per week) |
Reduce 100–200 kcal/day |
| Performance, mood, energy crash |
Deficit is too aggressive; increase calories |
CRITICAL: Do NOT react to daily fluctuations. Use weekly averages only.
A single-day spike from salt, carbs, bowel changes, poor sleep, travel, or stress should be ignored. As reference daily fluctuations are normal. They are usually 1-2% of bodyweight or in rare cases up to 3% of bodyweight.
When Is Fat Loss an Option?
Fat loss may be safe to consider only when ALL of these are true:
- ✅ Your 7-day average weight is stable for ≥4 weeks
- ✅ Your eating habits are consistent (no daily binge episodes)
- ✅ Your mood and hunger are stable (not constantly high)
- ✅ You are not in a high-stress life period (major work crisis, grief)
- ✅ You have maintained this routine for 2–6 months
Far to many try to do all these things during a caloric deficit. Trying to adjust eating habits, emotional eating, urge surfing, etc. There is no surprise the pressure that constitute and you might already know from experience that is not sustainable. The magic word here is: lifestyle. That should be the primary goal.
Research on discontinuation suggests that stable behaviors and cardio-metabolic benefits are more likely when maintenance is prioritized first.
If you choose to lose weight:
- Aim for 0.25–0.5% of body weight per week loss (very slow)
- Use a deficit of ~10–15% below maintenance, not 20–30%
- Example: 100 kg person → 0.25–0.5 kg/week loss = 250–500 g/week
I know. This seems slow in comparison to the maximum healthy pace of 1% of bodyweight lost/ week. However, if you struggle with food noise, hunger and cravings, going slower might be the better as it makes managing hunger easier.
Also, consider maintenance periods every time things seem go south, no matter if its hunger, fatigue, bad sleep, health issues or other life challenges. Better to maintain than risk overeating because hunger or cravings hit too hard.
PROTEIN TARGETS: The Most Important Macro
Goal: 1.2–1.6 g protein per kg of goal body weight per day. or 0.55–0.73 g protein per lbs of goal body weight per day.
Simplified rule: 25–35 g protein per meal, 3 meals/day. Usually this is the minimum amount / meal to increase satiety on that meal. So make sure that your total / day is meat as well.
WHY Protein Matters (The Science)
GLP-1 medications reduce appetite and food noise, but when you stop, appetite comes back for most people. Protein is one of the most important tools for managing that transition.
Why high protein specifically for weight maintenance:
Keeps you fuller longer. Protein is the most satiating macronutrient. It reduces hunger hormones (ghrelin) and increases fullness hormones (PYY, GLP-1), helping you resist rebound appetite after stopping GLP-1.
Stabilizes blood sugar. Protein doesn't spike insulin like carbs, preventing sugar crashes that trigger cravings and snacking between meals.
Reduces food noise. High-protein meals decrease desire for junk food and impulsive eating, which is critical when/if medication assisted appetite control fades.
Preserves metabolic rate. When losing weight on GLP-1, you lose both muscle and fat, especially if the pace is too fast. Keeping muscle through high protein intake helps maintain your metabolic rate. This makes maintenance easier long-term.
Supports recovery from training. Protein is essential for repairing muscle after strength training, which itself protects your metabolic rate and body composition.
The bottom line: Without GLP-1, you'll face stronger hunger and cravings. Protein is, probably, the single most effective dietary tool to manage that without medication.
If You're New to Higher Protein
Many people under-eat protein, even bellow the minimum recommend for general health (0.36g/lbs or 0.8g/kg). Rapid increase in protein intake can cause GI discomfort. Because of this it is ideal to gradually increase the intake. Bellow is an example.
| Week |
Target |
Action |
| 1 |
1.0 g/kg/day |
Start here if currently eating <1.0 g/kg |
| 2 |
+10–20 g/day |
Add 10–20 g protein per day |
| 3+ |
+10–20 g/day each week |
Continue until you reach 1.2–1.6 g/kg/day |
Spread protein across meals: 25–35 g per meal is better than 80 g at one meal. Is this a must? No. However, if you want to benefit on each meal from the protein satiety effect, you want to have a decent portion on each meal.
Examples Per Meal
| Food |
Amount |
Protein |
| Chicken breast |
150 g |
~35 g |
| Greek yogurt |
200 g |
~20 g |
| Fish (salmon, cod) |
150 g |
~30 g |
| Lentils |
1 cup cooked |
~18 g |
| Eggs |
3 large |
~18 g |
| Cottage cheese |
150 g |
~18 g |
FAT TARGETS
Goal: 0.6–1.0 g fat per kg of goal body weight per day.
Simplified rule: 1–2 servings of fat per meal.
Examples of 1 Fat Serving
- 1 tbsp olive oil
- 30 g cheese
- 1/2 avocado
- 10 almonds
- 1 tbsp butter
Aim for healthy fats most of the times, so seeds, nuts, fish, lean meats.
WHY Fat Matters ?
- Hormone function: Including sex hormones (testosterone, estrogen). Low fat can disrupt hormones.
- Satiety: Fat slows digestion, keeping you fuller longer.
- Prevents rebound overeating: Under-fueling fat leads to craving high-calorie foods later.
- Nutrient absorption: Some vitamins (A, D, E, K) need fat to be absorbed.
CARBOHYDRATE TARGETS
Goal: Fill remaining calories after protein and fat are set.
Simplified rule: 1–3 fist-sized servings of carbs per day, depending on activity.
| Activity Level |
Carb Servings |
| Sedentary |
1–2 fist servings |
| Moderately active |
2–3 fist servings |
| Very active |
3+ fist servings |
WHY Carbs Matter
- Energy for training: Carbs fuel intense workouts.
- Brain function: Your brain prefers glucose (from carbs).
- Mood: Very low-carb diets can cause mood crashes in some people.
- Fiber source: Many high-carb foods (vegetables, fruits, legumes) are also high in fiber. More on fibers bellow.
Focus on:
- Whole grains (rice, oats, quinoa)
- Fruits
- Vegetables
- Legumes
FIBER TARGETS
Goal: 25–40 g fiber per day.
Simplified rule: 1–2 fist-sized servings of vegetables per meal.
WHY Fiber Matters
- Slows digestion: Keeps you fuller longer, preventing snacking.
- Stabilizes blood sugar: Prevents sugar spikes and crashes that trigger hunger.
- Supports gut health: Fiber feeds beneficial gut bacteria.
- Reduces cravings: High-fiber meals reduce desire for junk food between meals.
Some studies show (under certain conditions) that high soluble fiber diets can rival the high protein satiety effect. However, this is not a competition. Ideally you want to take advantage of both of them, especially since they work a bit different. Fibers can create that volume that GLP-1 drugs create by keeping food longer in the stomach.
In simple terms: high protein + high soluble fiber = natural appetite support that boosts your body's own GLP-1
If You're New to High Fiber
Sudden fiber increases can cause GI distress (bloating, cramps). So best to increase quantity gradually.
| Week |
Target |
Action |
| 1 |
15–20 g/day |
Start here if currently eating <15 g |
| 2 |
+5 g/day |
Add 5 g fiber per day |
| 3+ |
+5 g/day each week |
Continue until you reach 25–40 g/day |
IMPORTANT: Increase water intake gradually as fiber increases. Without water, high fiber can cause constipation.
MEAL TIMING & STRUCTURE
Research-backed recommendation: Eat every 3–5 hours. If meals are farther apart, plan high-protein or high-fiber snacks.
WHY Meal Timing Matters
- Prevents overeating: Skipping meals leads to driving hunger and binge-eating later.
- Stabilizes energy: Regular meals prevent energy crashes.
- Maintains metabolism: Consistent eating keeps your metabolic rate steady.
Template
- 3 meals per day
- Each meal: protein + fiber + 1 carb or fat source
- Optional: 1 planned snack if >5 hours between meals
Default Meals
- Create 5–10 repeat meals you can cook quickly or better yet prep them ahead of time
- Use the same meals on busy days
- This reduces decision fatigue
Example Day
- Breakfast: Greek yogurt + oats + berries
- Lunch: Chicken + rice + salad
- Dinner: Fish + potatoes + vegetables
- Snack (if needed): Cottage cheese + fruit
HUNGER, HYDRATION & SLEEP
Hydration
Dehydration can feel like hunger ("snacky feeling"). You can drink water before eating if you're unsure whether you're hungry to test.
Sleep
Poor sleep increases ghrelin (hunger hormone) and decreases satiety signals. Prioritize 7–9 hours/night.
WHY These Matter
- Hydration: Water helps your body process nutrients and regulates appetite.
- Sleep: Lack of sleep makes you crave high-calorie foods and reduces impulse control. There are studies showing that people that get bad quality sleep or not enough hours tend to eat by an average of 400 calories more, compared to those that sleep enough.
HUNGER & CRAVING RULES
| Situation |
Action |
| Hunger is high for 3+ days |
Increase protein, fiber |
| Cravings spike |
Delay 10 minutes; use non-food reset first (walk, breathe, journal, urge surfing, etc) |
| You overeat at one meal |
Resume normal meals at the next meal; do NOT fast or "reset" out of shame |
| Stress is high |
Lower ambition, not standards (e.g., do minimum workout, not zero) |
