When we lose weight, it’s not always just fat that disappears.

If the process isn’t done carefully, we also lose muscle mass—which is a big deal.

Muscle is like your body’s internal scaffolding.

It gives your physique its shape and holds your skin in place.

If you lose muscle during a crash diet without strength training or enough protein, that structure disappears.

Fat vanishes, but now there’s nothing to anchor your skin to.

Think of it like a cushion. Remove the stuffing, and the fabric goes limp.

That’s exactly what happens to your skin without that inner support.

But here’s the catch: it doesn’t have to be that way.

People who lose fat gradually, while eating enough protein and doing resistance training, usually preserve or even build muscle.

As a result, their skin stays firm, or at the very least, doesn’t sag noticeably.

And sure, you might still get some stretch marks, but that’s normal.

They fade.

They’re not flaws, they’re marks of progress.

Let me share a story.

One of my clients, let’s call her Rhea, had battled with yo-yo dieting for years.

Eventually, she lost 18 kilos through extreme calorie restriction and hours of cardio.

And yet—despite the number on the scale, she felt disheartened.

Why?

Because she was left with sagging skin around her stomach and arms.

‘I thought I’d feel proud,’ she told me.

‘But now, I hide my arms behind long sleeves.’

When we looked at her journey, it was clear.

She lost fat, but also lost muscle, and that made all the difference.

Back to Rhea.

Once we adjusted her approach, everything started to change.

We slowed her fat loss down.

We added weight training.

We focused on whole, nutrient-dense meals. And the result?

Over the next year, her body composition transformed.

The loose skin on her arms began to firm up.

Her abdomen tightened.

And it wasn’t magic, it was muscle.

It was strategy. It was science, applied with patience and consistency.

Skin elasticity depends on three key things:

1. The speed of your weight loss

2. How much muscle you maintain or build

3. Your age and genetics

While you can’t change your age or DNA, you can control how quickly you lose fat and whether you protect your lean mass.

That means:

1. Avoid crash diets

2.  Prioritize strength training

3.  Eat enough protein

4.  Stay hydrated

5.  Include skin-supporting nutrients like collagen, zinc, vitamin C, and healthy fats

We live in a world obsessed with speed—’Drop 10 kilos in a month!’  ‘Get shredded in 30 days!’

But sustainable fat loss is not a race. It’s a process.

The best results come from slow, deliberate progress that values muscle preservation and skin integrity.

So wherever you are on your journey, ask yourself:

1. Am I protecting my muscle?

2. Am I feeding my skin from within?

3. Am I giving my body the time to adapt?

If you’re already dealing with loose skin, don’t despair.

With the right habits, it can improve over time.

Your body has already done something incredible.

Now, it’s time to continue supporting it, with smart training, nutrient-rich food, hydration, and most importantly, compassion.
