Protein: how much you need, and where to get it
Most people trying to lose weight do better with more protein than they think. Start with your number from the calculator, then find the foods, meals and snacks that get you there.
Key facts
ParrotPal’s protein calculator aims for about 1.6 g of protein per kg of a healthy weight for your height, the level at which a review of 49 trials found extra muscle from protein, with strength training, levelled off. Practical aim: 25 to 30 g a meal. Our food diary data shows where members fall short.

What the research says
Protein supplements added to resistance training gave modest extra gains in muscle and strength, levelling off at about 1.6 g of protein per kg a day.

A systematic review, meta-analysis and meta-regression of the effect of protein supplementation on resistance training-induced gains in muscle mass and strength in healthy adults. British Journal of Sports Medicine 52(6):376–384. doi:10.1136/bjsports-2017-097608
Higher-protein diets during weight loss were linked with more fat loss and better preservation of lean mass in shorter trials, with about 25–30 g of protein a meal often suggested.
