At 6'2", 235 lbs., lifetime natural and Slovenian physician Blaž Hrastnik - Musclemania Pro says, "A body has its special “set point” of fat percentage where individual feels best. Go below that set point and you’ll feel lack of energy and your workouts wont be as efficient as they could be. So, fat is crucial as it has its own important role in metabolism. There’s a thin line between what our media projects as beauty and what is actually healthy. My fat levels on this photo are too low without a doubt. However i’m doing this extreme only for a very short periods of time."
