When healthy adult men are in a state of severe calorie deficit at high altitude, consuming 2.0 grams of protein per kilogram of body weight per day leads to a higher rate of protein breakdown compared to consuming 1.0 gram per kilogram, resulting in a greater overall loss of body protein.

When healthy adult men at high altitude consume significantly fewer calories than they burn for three weeks, they lose about 3.6 kilograms of lean body mass, whether they eat 1.0 or 2.0 grams of protein per kilogram of body weight daily.

If young guys lift weights hard and do intense workouts while eating less for a month, chugging 2.4 grams of protein per pound of muscle each day helps them gain more muscle and lose more fat than eating half that much protein.

If young guys eat more protein while working out hard and cutting calories for a month, they’ll gain more muscle and lose more fat compared to eating less protein.

Eating protein after working out doesn't make your body burn more protein as fuel than it needs for building muscle - most of the protein goes toward building muscle instead of being burned for energy.

Eating more protein every day for weeks or months makes your body burn more calories even when you’re resting, which might help prevent slow weight gain over time.
