Frequently Asked Questions

How many calories should I eat to lose weight?

A deficit of 500 calories per day typically produces about 1 pound of weight loss per week (since 3,500 calories approximately equals 1 pound of fat). Start with a modest deficit of 15–20% below your TDEE and adjust based on actual results over 2–3 weeks.

What is the difference between calories and TDEE?

A calorie is a unit of energy. TDEE (Total Daily Energy Expenditure) is the total calories your body burns per day from all sources: metabolism at rest, digestion, and physical activity. Your daily calorie goal is set relative to your TDEE — below it to lose weight, at it to maintain, above it to gain.

What is the best macro ratio for weight loss?

A common ratio for weight loss is 40% protein, 30% carbs, and 30% fat. Higher protein helps preserve muscle mass while in a calorie deficit.

How much protein do I need to build muscle?

Aim for 0.7 to 1 gram of protein per pound of body weight when building muscle. This ensures adequate amino acids for muscle protein synthesis.
