Why does fat loss take 3 months?

Fat cells renew approximately every 90 days.

Human cells are constantly renewing, with new cells being generated and old cells dying daily.

The cell renewal cycle generally takes about 90 to 180 days.

Specifically:
- Stomach cells renew approximately every 7 days,
- Skin cells renew approximately every 28 days,
- Fat cells renew approximately every 90 days,
- Red blood cells renew approximately every 120 days,
- Liver cells renew approximately every 180 days,
- Bone cells take a year to renew.

In about a year, 98% of the body's cells will have been renewed.

As an essential part of the human body, fat cells are constantly being generated to replace those that naturally die.

This means the body must strictly control the number of fat cells.

Therefore, fat cells do not naturally disappear due to external forces or exercise.

In adults, weight gain or loss usually only changes the size of fat cells.

Why does weight quickly rebound after rapid weight loss?

This happens because the fat cell renewal cycle hasn't been completed. Sticking to weight loss for three months or longer allows your body's fat cells to be completely renewed, all turning into normal-sized new cells. Otherwise, you'll fall into a vicious cycle of regaining and losing weight repeatedly.

The body has memory. When hair falls out, new hair grows in the same place, not on the face or other areas. Small wounds on the body will heal, which is the body's memory.

Similarly, our body remembers its shape. When fat cells drop rapidly, the body activates a protective mechanism to prevent rapid fat loss, slowing down abnormal fat consumption.

That's why people on extreme diets often rebound quickly after eating a bit more. The fat primarily accumulates in areas where it was previously lost, especially in the "critical zones" like the waist and abdomen. This is a self-protection mechanism of fat cells.

For example:

If your weight is stable at 64kg and you lose 5kg in twenty days, your body is still likely to regain those 64kg within 90 days. Why?

Because your body has firmly remembered the weight of 64kg.

1. Maintain healthy exercise habits, practicing daily to achieve physical habituation.
2. Eat healthily, consuming more nutritious foods to ensure the body gets necessary nutrients during weight loss.
3. Weight loss is a long-term habit. After reaching your target weight, you need to spend another three months consolidating it so your body can remember your current shape.
