i would think that if u eat only one meal a day, the body would store most of the energy from the food as fat, that it would be released slowly till next meal, so less meals u eat the more fat u store, the more fat u use as energy. Thats y u will prob get tired during parts of the day if u eat only one meal. Eating increases metabolism, i know i store more fat if i only eat once a day. adonis needs to stop trying to shove his principles down our throats, the flex diet is for pros who use a lot of juice, but we can eat 3 meal a day , normal food, and maybe couple of shakes and still grow well, and be lean.
