What protein foods are best for weight loss?

−

Best protein foods for weight loss: chicken breast (165 cal/100g, 31g protein), egg whites (17 cal each, 3.6g protein), canned tuna (100 cal, 22g protein), Greek yogurt (97 cal, 10g protein), shrimp (99 cal, 24g protein), and lentils (116 cal, 9g protein).

Does eating protein help you lose weight?

−

Yes, significantly. Protein boosts metabolism by 80–100 calories per day through its thermic effect. It reduces appetite hormones and increases fullness hormones. High-protein diets consistently produce 2–3x more weight loss than high-carb, low-fat diets in studies.

How much protein should I eat per day to lose weight?

−

For weight loss, aim for 1.2–1.6g of protein per kg of bodyweight. For a 70kg (154 lb) person, that's 84–112g daily. This level preserves muscle mass during a calorie deficit, which prevents your metabolism from slowing down.
