Discussions regarding optimal protein intake have focused on balancing quantity, quality, and timing for various health goals. At a nutrition conference, experts suggested a “sweet spot” of 1.2–1.6 grams of protein per kilogram of body weight for most adults to support muscle maintenance and healthy aging. Some researchers proposed a “protein nudge” to help specific populations meet these needs.

Subsequent guidance for muscle mass gain has suggested higher daily ranges, specifically between 1.6 and 2.2 grams per kilogram of body weight. While traditional advice often limited protein per meal to 20–30 grams, newer evidence indicates that larger doses of 70–100 grams can expand and prolong muscle protein synthesis. Experts also note that the timing and type of protein, such as fast-absorbing whey versus slow-digesting Greek yogurt, play roles in how the body utilizes amino acids.
