That's fasting not under eatting; who cares some thing lol.
There's some thread on bb.com or something where the guy talks a lot about it, he's pretty shredded, if you haven't seen it might be something worth checkin gout.
7DS is right, there is a difference between fasting and undereating.
Fasting = long periods of time without nutrition where the body goes purely catabolic and starts burning everything (muscle and fat)
Under Eating = eating at regular or semi-regular intervals but not getting enough total nutrition to support muscle growth and/or fat loss.
The idea is simple - yes, you can in fact gain muscle and lose fat by doing a "warrior diet" style plan where you basically eat one giant meal per day and fast for the rest of the day...however here is the science involved.
In one sitting the body can only digest and assimilate approximately 30-50g protein, 50-60g carbohydrates, and 20-30g fat. This is assuming that all of these are digested at the same time. However, if you have slow digesting, medium digesting, and fast digesting proteins/carbs/fats all at once in your meal, then you will have: 30-50g protein, 50-60g carbs and 20-30g fat immediately (2 hours), and sustained within 4 and 8 hours, as well as a total intake of approximately 150g protein 180g carbs and 90g fat (maximum).
This results in sustained nutrition for SOME growth and SOME fat loss - HOWEVER you are also causing the body stress from doing this. If you feed the body only once per day, during this time the body goes highly anabolic and starts holding onto everything you give it, first prioritizing the allocation of atp and amino acids. Once all of those are used immediately, the rest is stored as fat as a failsafe in case food might not come at regular intervals to sustain energy. Then you immediately and continuously stop eating for the rest of the day and force the body and all of your biological processes (especially when you are training at the gym and burning tons of calories) to go into a deep catabolic mode and start burning everything stored in the body (fat and muscle tissue will both be attacked).
Now if you take MASSIVE doses of BCAA's throughout the day...you can prevent quite a bit of muscle loss....but at the same time your muscular gains will NOT be substantial. In addition, your internal organs, body chemistry (chemical and hormone release) as well as overall health and wellness will suffer over time.
A diet such as this sustained over many years will result in irreversible damage to any/all of the internal organs, metabolism, hormone production (ESPECIALLY TESTOSTERONE which is stimulated through cholesterol consumption throughout the day), sex drive, brain function, etc.
If you want the MOST gains and BEST physique...stick to the tride and true...which is a simple 3 part phase...
Bulking - 8 months
Cutting - 3 months
Maintenance - 1 month
Eat frequently and keep your metabolism burning fat while also keeping your body happy.
Work out hard (but certainly not on a full stomach) to stimulate fat burning
Take BCAA's to avoid muscle loss while working out or between meals
Eat plenty of the right food post-workout to sustain the muscle repair needed
eat the right foods before bed to sustain metabolism throughout the night but also allow fat burning
