Protein timing

Protein timing is the practice of ingesting protein according to a particular schedule, usually with hopes of reaching a particular health goal. Most protein timing plans are meant to maximize muscle growth following workouts for athletes and bodybuilders. Traditionally, this involved taking significant amounts of protein shortly after a workout, generally within two hours, in the belief that the body was more receptive to nutrients during that time. Subsequent research has shown that this may be helpful for many, though results are not conclusive. For most people, balancing protein intake through the day in nutritious meals and snacks is generally the healthiest method for gaining or maintaining muscles and losing weight.

Overview

Protein is an extremely important nutrient. It is best known for its role in muscle growth, but it also contributes to the formation and maintenance of tissues, bones, hair, and skin. Protein can help to combat infections, oxygenate the blood, reduce body fat, and build energy the body needs to function. To maintain good daily health, the average person should take in approximately 7 grams of protein for every 20 pounds of his or her body weight, according to the National Academy of Medicine.

This nutrient comes from many sources. Common dietary sources of protein include meat, fish, poultry, milk, eggs, nuts, beans, legumes, and seeds. Protein can also be produced in powder form, most often for use in dietary supplements. Some of these powders are dairy-based proteins such as whey and casein, and plant-based powders such as soy, pea, hemp, and rice protein. Many athletes and people with little time to eat use these powders because they are convenient and concentrated.

Although the value of protein is not in question, medical and fitness experts disagree on protein timing, or the best times of day to take protein. Many sources and studies hold that protein is best used on a specific schedule to maximize benefits such as muscle growth. Many other experts believe that the effects of protein timing are minimal, nonexistent, or mainly dependent on the individual user.

Professional athletes and serious bodybuilders have been using various techniques of protein timing since the last half of the twentieth century. In general, most athletes seeking to build muscle mass take protein within two hours after a workout. Some aim to take the protein very shortly after working out, believing the time from around fifteen to sixty minutes after the exercise is a so-called “anabolic window” during which the body is particularly receptive to nutrients.

Scientists have researched this practice and found that it may hold some benefits. However, their research is not conclusive for several reasons. One reason is that most of the protein users in the studies are serious athletes with far more rigorous lifestyles than the average person. In addition, most of the studies relate to short-term, rather than ongoing, health results.

People who use protein to lose weight or to prevent muscle loss without heavy exercising generally eat protein throughout the day. Eating healthy, protein-rich snacks, such as nuts or legumes, between meals can help to reduce hunger, overeating at meals, and unhealthy snacking. Eating high-protein whole foods such as fish and poultry is also a good way to get filling, nourishing protein sources for daily health. Some experts also recommend taking protein before bed, as the nutrient can bring benefits to the body through the course of sleep.
