Why the weight won't come off, even when you eat less.

You eat roughly the same as before. You move just as much. And yet, the weight settles in.

Discipline explains almost nothing. Metabolism, on the other hand, explains almost everything: the way your body handles blood sugar decides what it stores and what it uses.

Every time you eat carbs (bread, pasta, rice, but also a dish that looks perfectly healthy: poke bowl, salmon wrap, granola), blood sugar climbs. Insulin is released to bring it back down. What isn't burned right away is stored as fat.

Two to four hours later, blood sugar crashes. Too fast.

The brain panics:

You snack. The cycle starts again. The body never really uses its reserves, because it's constantly being topped up with fast carbs. Over ten years, that's how the weight quietly settles in, especially around the belly and hips.

1. Restrictive diets. They work. For eight to twelve weeks. Then the body, which had to be starved to lose weight, lowers its base metabolic rate. As soon as the diet ends, the lost weight comes back, plus a few extra. That's the yo-yo effect, documented since the 90s.

2. Exercise. Essential, but rarely enough on its own after 35. Exercise burns calories. It doesn't change the way insulin drives storage. You can run three times a week and still gain belly fat, because storage happens on the hormonal side, in insulin, more than in calorie burn.

3. Prescription GLP-1 injections. Since 2023, these weight-loss injections have taken over women's magazines and nutritionists' clinics. They all work with the same molecule: GLP-1, the satiety hormone that slows digestion and steadies blood sugar. The injection is a synthetic copy of a hormone your body already makes.

• Price: €200 to €400 per month.
• Frequent side effects: nausea, constipation, digestive fatigue.
• Dependence: when you stop, the weight comes back in most cases.

That's the question Amandine De Paepe, a Belgian food scientist, orthomolecular nutritionist and founder of Insentials, spent ten years researching.

Rather than replacing the hormone with a synthetic molecule, her team went the opposite way: isolating a combination of plant actives capable of waking up the body's natural GLP-1 production, and slowing the absorption of carbs upstream.

The patent is called Glucoreductase™. It works on two levels:

1. In the gut, by slowing the absorption of carbs. The blood sugar curve smooths out, the insulin spike is dampened, the body stores less.
2. At the intestinal L-cells, by stimulating natural GLP-1 production. Satiety lasts longer, with no injection.

This mechanism is at the heart of the Metabolic GLH-2 Pack : three supplements designed to work together on the liver, blood sugar and energy metabolism. Detox Boost supports the liver's natural functions, the foundation of metabolism. GLH-2, the Glucoreductase™ capsule taken before your main meal, slows carbohydrate absorption and stimulates natural GLP-1 production. Fat Burner rounds out the approach by contributing to normal energy metabolism, as part of a calorie-controlled diet and regular physical activity. Awarded by the ELLE Beauty Awards 2026jury.
