What is protein?

It is a macronutrient, that keeps our body tissue strong and can be used as an energy source.

How much should I eat?

The American College of Sports Medicine (ACSM) recommends you consume 0.8g per kg of body weight (0.35g/lb) for maintenance and 1.2-1.7g per kg of body weight (0.5-0.8g/lb) to increase muscle mass.1

When is the best time to consume protein?

There have been many research articles on this over the years, with the old belief that you needed to consume protein within two hours of working out for the best possible results. However, recent research says otherwise:

A study found that groups consuming before exercise (and not within 3 hours after exercise), had similar changes in body composition and strength compared to the group that consumed protein after exercise.2

There were shown to have a positive impact of protein supplementation of lean body mass of older adults independent of the timing of protein intake.3

Protein timing had no effect on lean mass, strength, and functional capacity gains over an eight weeks study.4

What does this information mean?

The timing of your protein consumption is likely not as important as the amount you are eating throughout the day.
