Frequently Asked Questions
What's the best macro ratio for losing fat?
▼
A high-protein split (35-40% protein, 25-35% carbs, 25-35% fat) works best for most people. Protein preserves muscle and increases satiety. Adjust carbs and fats based on your preferences.
Should I track macros or just calories for weight loss?
▼
Tracking macros is better if you want to preserve muscle and optimize body composition. Tracking just calories works for weight loss but doesn't ensure you keep muscle or stay satisfied.
How much protein do I need to lose weight?
▼
Aim for 0.8-1g per pound of body weight, or 1-1.2g per pound of lean mass. This is higher than typical recommendations but research supports higher protein for dieting individuals.
Can I eat carbs and still lose weight?
▼
Absolutely. Carbs don't cause weight gain - excess calories do. Many people lose weight successfully eating 40-50% carbs. Cut them if you prefer, but it's not necessary.
Do I need to hit my macros exactly every day?
▼
No - close is good enough. Focus on hitting protein daily, then aim for weekly averages on carbs and fats. Being within 5-10g of targets is fine.
Should I eat different macros on rest days?
▼
You can reduce carbs slightly on rest days (since you're not fueling workouts) and keep protein the same. But the difference is small - consistency matters more than optimization.
