— Understanding Fat Cells and the True Mechanism of Weight Gain —

“Is it true that liposuction prevents rebound weight gain?”

This is one of the most common questions from patients.

The answer is:
Liposuction creates a body that is less likely to regain fat.
However, it does not mean you will never gain weight again.

Let’s understand this from the perspective of fat cells.

■ How Does Fat Increase?

There are two ways fat increases:

• Enlargement of fat cells (hypertrophy)
• Increase in the number of fat cells (hyperplasia)

In adults, the number of fat cells rarely changes.
Weight gain mainly occurs because fat cells become larger.

■ What Happens During Liposuction?

Liposuction physically removes fat cells, reducing their total number.

• Diet → fat cells shrink
• Liposuction → fat cells are removed

This difference is the key to why liposuction results are more stable.

■ Why Is Weight Regain Less Likely?

When the number of fat cells decreases,
there are fewer “storage units” for fat.

As a result:

• Weight gain occurs more slowly
• Treated areas are less likely to accumulate fat
• Body contours are easier to maintain

This is why liposuction is considered “resistant to rebound.”

■ Why Do Some People Still Gain Weight?

This is very important.

Even after liposuction:

• Remaining fat cells can still enlarge
• Untreated areas can accumulate fat

In other words,
lifestyle still matters.

Factors such as:

• High-calorie diet
• Lack of exercise
• Poor sleep
• Chronic inflammation (stress, smoking)

can all promote fat accumulation.

■ The True Value of Liposuction

Liposuction is not just about losing weight.
It is about changing how your body gains fat.

• Creating areas that are harder to gain fat
• Controlling fat distribution
• Making body contours more stable long-term

In other words,
it creates a body where your efforts produce better results.

■ AVAN TOKYO’s Approach

At our clinic, we do not simply remove fat.
We carefully design what to remove and what to preserve.

• Sculpting the arms to a sharp, refined line
• Creating vertical waist definition from the back
• Designing harmony with the breast contour

Liposuction is not about removing fat randomly—
it is a line-based artistic design.

■ Final Message

Liposuction is a powerful procedure
that makes weight regain less likely.

But the essence is:
reducing fat cell numbers and changing fat distribution.

With proper:

• Diet
• Exercise
• Lifestyle

your results can be maintained long-term.
