The Best Time to Eat Protein and Build Muscle Health: You May Want to Rethink Breakfast
New research from Waseda University says that it's best for muscles if we eat protein at breakfast. Here's the specific amount to ingest.

Proteins constitute an essential dietary component that help in the growth and repair of the body. Composed of long chains of amino acids, they promote the growth of skeletal muscles—which is the group of muscles that help us move.
Humans have been aware of the benefits of proteins for a long time. However, recent studies have shown that having the right amount of protein at the right time of the day is essential for proper growth.
This is called Chrononutrition—which looks at how when you eat is as important as what and how you eat.
The reason behind this is the body’s internal biological clock.
Called the circadian rhythm, this rhythm is followed by all cells and controls life functions like metabolism and growth.
Interestingly, protein digestion and absorption have been found to fluctuate across day and night according to this clock.
Moreover, earlier studies have reported that intake of protein at breakfast and lunch promotes skeletal muscle growth in adults.
However, details on the effect of the time of protein intake on muscle growth and function have remained elusive until now.
Fortunately, researchers from Waseda University, led by Professor Shigenobu Shibata, recently endeavored to understand the effect of the distribution of protein intake through the day on muscles.
They fed laboratory mice two meals per day containing either high (11.5% by proportion) or low (8.5% by proportion) protein concentrations.
The researchers noted that protein intake at breakfast induced an increase in muscle growth, determined by assessing induced hypertrophy of the plantaris muscle in the leg, when compared with the effects of protein intake at dinner.
