Is Eating Protein Every 2-3 Hours Better For Results?

Protein timing is a hot topic.

Honestly, you could probably start an argument in your local gym by yelling “How often should I eat protein throughout the day?”

You see, some people believe that you should eat protein every 2-3 hours in order to provide your body with a constant stream of those all-important muscle building amino acids, but others believe that it doesn’t really matter provided you hit your daily protein target overall.

It seems they’re quite willing to scrap over this one, so I’m going to settle it once and for all by taking a deep-dive into the science on protein timing!

The Theory Behind Protein Timing

This is a “trick” which bodybuilders have been using for decades.

The theory is that spreading your protein intake throughout the day (as opposed to having 2-3 main meals) will create a constant stream of amino acids, which should lead to greater uptake and help make better use of the protein you eat.

Essentially, two people could eat the same amount of protein and see different results, provided one was smart about protein timing and the other wasn’t.

Are There Any Studies On This?

Yes indeed!

Back in 2012, researchers from Switzerland published a trial on this topic. where trainees were given a total of 80 grams of whey protein after a leg workout, and it was divided into the following categories:

• Group A had 80g protein (10g every 1.5 hours)
• Group B had 80g protein (20g every 3 hours)
• Group C had 80g protein (40g every 6 hours)

All of the trainees saw improvements to muscle protein synthesis, protein turnover, and protein breakdown, but the second group (20g every 3 hours) saw the best results overall. (1)

This group also achieved a superior net protein balance and higher protein metabolism, which shows us that spreading your protein intake over regular intervals throughout the day can lead to better muscle building results!

However, it’s worth noting that the improvements were pretty small, so don’t feel like you need to overhaul your entire lifestyle if it’s going to cause you any problems.

After all, dietary adherence is (by far) the most important factor in achieving long-term results, so if you currently prefer to eat your daily protein intake across 2-3 main meals and it’s working for you, then I don’t see any reason to change that. (2)

However, those of you who enjoy trying new things have just found an extra muscle building tool you can use!
