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

You eat roughly the same as before. You exercise too. Yet the weight keeps coming on.

Discipline explains almost nothing. Metabolism explains almost everything: the way your body manages blood sugar determines what it stores and what it uses.

Every meal containing carbs (bread, pasta, rice — and also dishes presented as healthy: poke bowl, salmon wrap, granola), blood sugar spikes. Insulin is released to bring it back down. What isn't burned immediately 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 truly taps into its reserves, because it's constantly resupplied with fast carbs. Over ten years, it's the weight that quietly settles in, especially around the stomach and hips.

1. Restrictive diets. They work. For a short period of time. 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 after 35. Exercise burns calories. It doesn't change how insulin makes the body store fat. You can run three times a week and still gain belly fat, because storage is hormonal — driven by insulin, not calorie expenditure.

3. Prescription GLP-1 injections. Since 2023, these weight-loss injections have taken over the wellness press. They all work with the same molecule: GLP-1, the satiety hormone that slows digestion and stabilises blood sugar. The injection is a synthetic copy of a hormone your body already produces.

• Cost: €200 to €400 per month.
• Common side effects: nausea, constipation, digestive fatigue.
• Dependency: when you stop, the weight returns in most cases.

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

Rather than replacing the hormone with a synthetic molecule, her team worked in the opposite direction: isolating a combination of plant-based actives capable of reawakening the body's natural GLP-1 production, and slowing carbohydrate absorption upstream.

The patent is called Glucoreductase™. It acts in two places:

1. In the gut, by slowing carbohydrate absorption. The blood sugar curve flattens, the insulin spike is dampened, the body stores less.
2. In the digestive system, by stimulating natural GLP-1 production. Satiety lasts longer, without an injection.

The supplement is called GLH-2. One capsule before the main meal. Winner of the ELLE International Beauty Awards 2026 jury. Used by over 50,000 women in Belgium, France and the Netherlands, as part of a balanced lifestyle and regular physical activity.
