My name is Martin Berkhan, nutritional counselor, fitness magazine writer and creator of Leangains.

Leangains is a unique approach to strength training and nutrition. The diet involves intermittent fasting and strength training in order to reduce fat mass and increase muscle mass. This is performed by switching between phases of overfeeding and underfeeding, as well as carefully manipulating the macronutrient ratio of the diet. My take on intermittent fasting and strength training will be the topic of an upcoming book project with nutrion guru Lyle McDonald, author of The Ketogenic Diet and The Ultimate Diet 2.0.

Updates (July 27th to Aug 31th)

31/8 Update:

Michael Novak (from the testimonials section) takes the 16/8 concept of intermittent fasting to the masses – check out the link. Michael is shown in picture number 6.

27/8 Update:

Still alive and kicking it, just been very busy lately, therefore the lack of any new updates. I’ve had a large influx of new clients and it’s good to see trainees on various internet forums opening up to the IF approach. Seems like every board got it’s own thread on the topic and it oftens spurs some wild arguing between the yay-sayers and the nay-sayers. Somewhere in between you might find some worthwhile discussion. The thread usually goes out of hand when you have the 6-meal-a-day-eat-clean-or-die-nutters on one side and the IF fundamentalists on the other side. Arguing that we should be fasting every day just because our ancestors did it (and even that is up for debate) is almost as moronic as arguing for eating every 2-3rd hour to “stoke the metabolic fire” (hint: it’s a myth) or “staying anti-catabolic” (hint: a big meal may take more than 12 hrs to fully digest and will release a constant stream of amino acids during the process).

Keep checking in for the newsletter interview with me and Leigh Peele, should be up this week.

9/8 Update:

Did some deadlifting today, 600 lbs x 3 (270 kg)

Note that the innermost plates are 25 kg (55 lbs), which are regular sized plates; that is, they are the same dimensions as standard size 20 kgs (45’s) would be.

The other plates are rubber studded plates from Techno Gym, which are not standard size and have a much lower diameter than standard issue 20 kg plates.

Therefore: 20 kg (bar) + 2 x 25 + 6 x 20 + 8 x 10 = 270 kg / ~ 600 lbs

Difference between 25kg standard plate and 20kg gym plate
Note the size discrepancy between the 25 kg standard issue weights and the 20 kg Techno Gym weights.

8/8 Update:

Added three testimonials that I hope shows the diversity among the people that employ my methods.

Fitness and bodybuilding pro’s, to college students and pro gamers; there is an approach for everyone, regardless of training status.

You’ll find these in the testimonials section further down the page.

Questions and Answers section

The Leangains FAQ didn’t come up this week as I had planned. Too much stuff to do. On the other hand, I get a lot of questions sent to me regarding the Leangains approach and Intermittent Fasting, so im going to start posting some of the e-mails, along with my questions, in this section.

Why hasn’t anyone discovered this approach before?

Q: Excuse me for being blunt, but if this diet is all that, then why haven’t many people discovered it? Why do so many bodybuilding dietitians (almost unanimously) have their clients do your average 6-meals-a-day-3-hours-apart type of diet?

A: The reason for the fitness/bodybuilding community not having “discovered” the approach, I think depends on several factors.

  1. being stuck in old ways of thinking with regards to nutrition and, especially, meal frequency.

Many people believe that eating several small meals a day will some how “stoke the metabolic fire” and prevent “starvation mode” etc. You know how it goes. There’s also the rather absurd notion that about the body only being able to absorb 30-40 g of protein in a sitting and going longer than 3-4 hrs without eating will get you “catabolic”.

These myths and absurd notions gets repeated in eternum by the bodybuilding mags and other bodybuilding gurus/clowns. Noone would dare to go against the grain when the so called “truths” about proper nutrition is so heavily ingrained into the community.

  1. The empirical and scientific support for intermittent fasting, it’s health benefits and effects on human physiology, has only started to emerge (relatively) recently and is still an unknown concept for the uninitiated fitness enthusiast or layperson.
  2. the old approach “works” for sure (6 meals a day etc), so no reason to mess with it. However, it may not be ideal and it may certainly not be ideal for many people with regards to meal frequency.

With regards,


Leangains and athletes

Q: I’m curious about the authors’ thoughts on this diet approach for performance athletes. Is this targeted more toward those looking for body recomp?

A: Slight modifications and/or compromises needs to be done with regards to macros and meal timing, but outside of that I see no issues with it – exceptions being, perhaps athletes with very high energy requirements and/or doing more than one training session a day.
