Ever wondered why the weighing scale becomes your enemy? You eat less, exercise more, but in spite of that, the weight loss starts to taper off. Annoying, isn’t it? Turns out there’s actually a reason.
When you lose weight, your metabolism does not maintain the same energy expenditure setpoint set by your body. Your body adapts slowly to the changes that are occurring inside and around it.

Your body becomes lighter

Your body requires less energy to provide for the same daily functions. Everyday activities like walking and climbing stairs, and even supporting your own body weight all require fewer calories now that you weigh less.

So the initial calorie deficit has to become less over time.

Your resting metabolism could change

Your body uses energy even while you’re sleeping and while you’re sitting on the sofa. This is known as resting energy expenditure.

You will see a drop in resting energy expenditure while losing weight since there is less body tissue to maintain. The body can also be more efficient at utilizing the energy that it receives.

You’re moving less than you realise

This is probably the most underappreciated cause.

You may find you naturally become less active if you have to reduce your food intake for a long time. You may sit longer, walk less or just be less mobile without you even noticing.

These small differences can have a surprisingly large impact on your total daily energy expenditure.

Muscle matters

Weight loss isn’t just about the number the scale gives you. If you lose a lot of muscle, as well as fat, it can reduce your daily energy requirements even more.

That is why protein intake, regular movement and resistance exercise are all important through weight loss.

Your appetite can change too

Your body especially does not like to be in an energy deficit for long!

As weight lessens, hunger and satiety can change. You may feel hungrier, less satisfied after meals or have a harder time maintaining your eating habits.

It is not just about willpower. It is your body trying to compensate for your weight loss.

What is it to do if the weight loss slows?

It is not always “eat even less”.

A better option is to reevaluate the approach. Calories, protein, activity, sleep, hydration and consistency have all matter.
As your body changes, your nutrition plan may need to change.

Being structured, through some approaches such as low calorie ketogenic diets , can be useful for some people because you’ll have portion-controlled nutrition and a framework in place, so you don’t have to constantly calculate your carb and protein intelligence to keep yourself in a calorie deficit.

But the ultimate goal should not be simply a lower number on the scale, it’s to lose excess fat, support muscle, do good nutrition and form habits that can be sustained long-term.

A slowing metabolism does not indicate you are not working hard.

It indicates your body has adapted.

Instead of going against that adaptation and going on a never-ending diet, it is smarter to factor in what has changed and modify your approach to it.

“Weight loss is simply not a linear race. Your body changes along with it.”
