• Diet: The 'binge' of JLo and her boyfriend after their (absurd?) 10-day challenge without carbohydrates and sugar
  • Losing weight: is the keto diet effective for losing weight in a healthy way?

It is one of the most popular natural weight loss supplements for weight loss. Its name, carbohydrate blockers, suggest a very seductive promise . Suddenly, we imagine ourselves in a kind of ideal world in which we can get purple of pasta, pizza, chips and sweets without getting fat (the consequences of the 'festival' on health is another story) thanks to the almighty action of a pill-shaped superhero that eliminates the trace of hydrates in our body .

It would be beautiful, right? It could be but, as it usually happens with all 'shortcuts' or miracle solutions , the reality is that it is not.

But let's go by parts. What are carbohydrate blockers? "As their name indicates, they are supplements that reduce the calories from the carbohydrates we eat , blocking the enzymes necessary to digest starch, " explains Lina Robles, nutritionist at the Sanitas La Zarzuela University Hospital (Madrid).

What do they take to inhibit the digestion of starches, preventing them from turning into sugar? Robles crumbles the "mechanism" of operation wielded by those who bet on efficiency with little scientific documentation to back it up. "They usually contain phaseolamin (extracted from the white bean), which is an alpha-amylase inhibitor. This enzyme is produced in saliva and breaks down carbohydrates into small molecules so that the body can absorb them. The blocking action of the phaseolamina makes that the undigested carbohydrates can pass directly to the digestive tract to be expelled through the faeces, "says Robles.

Does this mean that we can even put on hydrate boots and that taking this pill we will not take even a kilo? "No, it is an aid that can be used (always under the supervision of a professional) if we are following a weight loss plan. They are not, in themselves, a diet and they do not compensate for binging on sweet " , clarifies this specialist.

Do they have side effects? Containing phaseolamin, derived from white beans, can cause flatulence and abdominal bloating . "In this case, unlike other similar products such as chitosan for fats (contraindicated in people with allergies to fish and shellfish), it does not cause health problems, but before taking any supplement, even if it is natural, you always You must go to the consultation of a professional who determines its relevance ", clarifies the doctor.

Moral? There are no shortcuts that are worth it. The objective must always be to acquire a healthy lifestyle, based on a balanced diet, physical activity and proper rest.
