We all need protein as part of a balanced diet and to stay healthy. Some people consume protein for specific reasons, such as to help them lose weight or gain muscle mass. However, it is not yet clear when the best time is to have that protein. There is some evidence that consuming protein can help a person lose weight, and there is clear evidence that it can help people build muscle mass if they also exercise. However, research, as yet, does not make it unclear when is the best time to have protein. It is also unclear if there is any best time at all, why this is the case, or whether it is the case for everyone.
Most people in the United States get enough protein in their diet. Still, the United States Department of Agriculture (USDA) say many people should vary the types of food containing protein that they eat. If a person is trying to build muscle mass, they may also take protein in the form of supplements to help them build muscle tissue after exercise.
There is some evidence that eating protein can help a person lose weight. Evidence suggests protein does this in part by increasing satiety. Satiety is the feeling of being full. Currently, there is little solid evidence regarding when the best time to eat protein might be to encourage weight loss. For example, researchers published a study in the journal Advances in Nutrition suggesting that eating snacks that contain protein may reduce the number of calories a person consumes at their next meal. However, the research paper also points out that studies demonstrating this are scarce and sometimes conflicting. They suggest more studies are needed to confirm their findings.
