Have you ever heard the saying, ‘If you lose weight by starving yourself, your skin will sag’?

It would be incredibly frustrating to work hard, exercise diligently, and control your diet to lose weight, only to find your belly sagging.

The success of a diet isn't just about the number on the scale.

A ‘beautiful diet’ that effectively sheds fat while keeping your skin firm and elastic is what true success looks like.

This is due to insufficient support from the muscle layer.

The abdomen has more subcutaneous fat and a thinner muscle layer compared to other areas.

Therefore, even if body fat is lost, if the muscles don't provide proper support,

the skin loses its elasticity and sags downwards.

It’s important to remember that if the abdominal muscles thin, the skin can lose its support and sag.

The most crucial first step is to lose weight gradually, at a rate of 0.5 to 1 kg per week.

This allows your skin enough time to adapt to the rate of fat loss,

minimizing the loss of elasticity.

Incorporate abdominal core muscle exercises.

Abdominal muscles play a crucial role in supporting the skin from within.

Therefore, consistently performing abdominal strengthening exercises like planks and leg raises alongside weight loss

will greatly help maintain a toned physique.

You must consume enough water and protein.

Water is essential for skin flexibility and recovery, so

I recommend drinking at least 1.5 to 2 liters per day.

There are also research findings indicating that consuming over 2 liters of water daily

increases skin hydration and elasticity indicators after 30 days.

Specifically, people who originally had low water intake

showed a significant improvement in skin biomechanical indicators.

This is due to a decrease in skin elastic fibers, specifically collagen and elastin.

As we age, the production of collagen and elastin in the skin decreases,

and frequent weight fluctuations or rapid weight loss can damage the skin's elastic recovery,

causing the thinned abdominal skin to fail to contract properly and sag.

In fact, a meta-analysis of large-scale randomized controlled trials (RCTs) reported that

oral collagen intake showed significant effects on improving skin elasticity and hydration.

If the skin is already significantly saggy and the abdominal muscles are also stretched,

non-surgical methods like lasers or thread lifts may not provide fundamental improvement.

In such cases, it’s important to remember that considering realistic and effective methods like abdominoplasty

is advisable.
