When we lose weight our stomachs produce more of the hunger hormone, ghrelin, which tricks our bodies into thinking it needs to eat more.

Ever wondered why you feel hungrier after you’ve lost weight?

You may have thought that it’s down to your body being used to you eating more food and it just needs to adjust, but you would only be partly right.

It actually comes down to the levels of the hunger hormone, ghrelin, in your body, according to new research.

Experts from the Norwegian University of Science and Technology discovered that when we lose weight our stomachs produce more ghrelin, thinking it needs you to consume more calories.

The bad news is, the levels of the hormone don’t adjust over time – they remain at higher levels.

So that means you are likely to feel hungrier on a daily basis.

Have you tried every diet and exercise trick on the planet and nothing’s worked? Maybe you’ve been missing the secret ingredient: psychology. Next time you consider a weight loss program make sure your brain doesn’t hold you back.

Lead author Catia Martins, an associate professor at the university, said: “Everyone has this hormone, but if you’ve been overweight and then lose weight, the hormone level increases.

“A person who’s been very obese has needed more energy just to breathe, sleep, digest food or walk.

“When the body loses weight, less energy is needed for these basic functions, simply because the body is lighter.”

The study followed 34 patients who were considered morbidly obese and put them on a two year weight loss plan.

The participants began weighing more than 19 stone on average.

They were given exercise plans and taught about nutrition.

On average they lost 1.7 stone over the two years.

But the reported feeling hungrier than before they lost the weight.

“Someone who has weighed 12 stone whole life can eat more than a person who is 12 stones after losing weight,” Catia.

“The difference in the amount of food is about 400 calories – the amount of a good breakfast or four bananas.”
