This is only the beginning of the problems with the “crash” approach to dieting, however, that has you enduring severe calorie deficits for extended periods: • You lose a lot of muscle, which not only leads to the dreaded “skinny fat” look, but it also impairs bone health and increases the overall risk of disease.3 • Your testosterone levels plummet and cortisol levels skyrocket, which not only makes you feel horrible but also accelerates muscle loss.4 • Your energy levels take a nosedive, you struggle with intense food cravings every day, and you become mentally clouded and even depressed.5
