This type of diet is the one with the most potential to do more harm than good. Many people used to think that dietary fat was what caused fat gain, which remains a common misconception. You know the truth now, that excess calories are to blame and fats are okay.
When your fat intake drops too low, your hormonal levels will suffer. Hormones, particularly reproductive hormones, are dependent on fat. For both men and women, removing too much fat from a diet can lead to decreased energy, mood swings, and a decreased sex drive. Women often report irregular menstrual cycles as well when dietary fat intake drops too low.
Even if weight loss is your primary goal, you should still be concerned with your overall health first and foremost. Cutting out fat may help you lose weight, but it’s probably going to have some serious negative side effects.
