In fact, a cutting period that lasts too long can indeed be harmful. When a person lives in a severe calorie deficit for months, the body begins to tire. Energy levels drop, sleep, mood, hormonal balance, and even immunity can be impaired. Some people experience problems with concentration, constant hunger, and irritability.

This can be especially difficult for the body when the body has a very low body fat percentage. The body begins to perceive this as stress. In men, testosterone can decrease, and in women, hormonal cycles can be disrupted. Therefore, professional athletes typically don't maintain "perfectly lean" shape year-round.

Most trainers believe it's safer to cut for a limited period of time and then return to a more normal and balanced diet. It's crucial not to go to extremes and try to lose fat as quickly as possible at any cost.

The healthiest cutting program involves a moderate calorie deficit, adequate protein intake, adequate sleep, and strength training. When a person loses weight gradually, the body tolerates it much more easily.

Ultimately, cutting itself isn't dangerous if done sensibly. However, constantly following a strict diet and chasing an excessively lean body can negatively impact your health over time.
