I've researched it some but still wanted some feedback if anyone's tried this. It will work well for my work schedule and from what I've read has good results in those that it has worked for.
It is tough to gain but I once tried it a few years ago, and I was astounded by the raw strength I held onto and how healthy my appearance became. I lost like 15 lbs though but was beyond shredded. It would work much better for someone with a sedentary style job and looking to be lean, pretty tough to bulk with just one meal per day, I actually ate 2 meals over 3 hour span I'd hit about 3k calories.
It's a variation of intermittent fasting....you should look at Berkhan's version, less intense, great results.
In his version you eat 2 or 3 meals after a fasting period. Easier to mow down 300g of protein that way. I eat around 250g protein split between two meals.
