Muscle synthesis requires adequate protein intake throughout the day. Grapefruit provides 2g of protein per 1 medium grapefruit, contributing to your daily target. For muscle building, most research supports 1.6 to 2.2g of protein per kg of body weight daily.
Grapefruit delivers 52.5 calories per gram of protein. Compare this against leaner protein sources if you are optimizing your protein-to-calorie efficiency.
The general guideline is 0.8g per kg for sedentary adults (roughly 50g/day), 1.2 to 1.6g per kg for active individuals (roughly 100g/day), and up to 2g per kg for athletes (roughly 150g/day). Grapefruit at 2g per 1 medium grapefruit can be a meaningful part of reaching those targets.
Cooking does not destroy protein, but it changes the weight and water content of Grapefruit. Raw and cooked weights differ, so always log Grapefruit by the state you are actually consuming it in. FitCommit's camera scanner handles both raw and cooked versions.
FitCommit's AI camera scanner identifies Grapefruit from a photo and logs protein and macros automatically. Track your daily protein goal in real time.
