sev, 600cals a day can be ok for obese ppl with diabetes 2type anf fatty liver.
this diet he does is exactly what some docs put such clients on.
however its bit low side for ppl who lift ofc, and hes shredded if compared to the general peasantery.
1200-1500 is fine for a while, esp with a reloading here and then and on gear.
@junior, well ibiza, if you live on 600cals a day youll look like dj120 till ibiza,or be dead or something lol.
I disagree. It is NOT healthy.
I was a programmed person in secret mind control experiments bla bla fucking bla .. when I started interacting with other people who lived through programming, I did notice a "trend". the very very low calorie diets or eating artificially induced at fist...400-800 cals a day. Not by accident, nazi concentration camps had the same amount of calories becasue they were massive mind control experiments.
This has zero to do with bodybuilding. When you deal with a specifically programmed person, throw out of the window the science books because their mind works differently and their body implicitly.
So when I spot the obviously familiar, I will call it out. But people think I am nuts. But I am not

Also, those specific people use sugars to regulate the blood sugar and cigarettes to ground. They are all very addictive personalities and are considered "weird" by the general population. However, when you understand all this mess, nothing is weird. Everything has a very logical scientific explanation.
So I would never advocate going under a certain number of calories. I believe in healthy eating and slight manipulations to get a desired look.
