That's hardcore. I know a few people who do it. My diet isn't great but I train alot. Your diet is the hardest part to get right.
I find it actually quite easy. I just dont eat anything during the day and spend the evening grazing. Now OMAD (one meal a day) is hard core. You eat all your calories for the day in the space of an hour. If your overweight its not so bad as all you do is eat till your full, then the fat on your body is the rest of your daily calories. But if your at maintenance like I am eating 2300 calories (my energy expenditure for the day according to online calcs) in one hour is really quite hard
I don't do any training (apart from my 90 mile per week commute) but that's my goal for the year. I'm still tweeking my 'personal food regime'
