We have all eaten it, often without giving it too much importance. He accompanies an entrance, completes a meal or in the form of juice, without us really dwelling on what he could change to our daily life. However, this fruit is talked about in a completely different context: that of metabolic regulation.
A measured effect on weight loss and blood sugar
It was a clinical study conducted by the clinic scripps, in California, which made it possible to document its effects. For 12 weeks, the researchers observed the evolution of two groups: one consuming this fruit before meals, the other not. Result: up to 1.6 kg weight loss in the first group, compared to only 0.3 kg in the second. No regime had been imposed.
This is the grapefruit. If he draws the attention of researchers, it is for his richness in ninguenin, a flavonoid capable of activating certain enzymes of the liver involved in the metabolism of the fat. In parallel, its low glycemic index Limits the rapid absorption of sugars, reduces insulin peaks and slows down the cravings that follow rich meals.
The right time to consume it
The effect observed in the study does not concern the fruit in itself, but the moment when it is consumed. Taken about 20 to 30 minutes before a mealin quarters or in a hurry (without added sugar), the grapefruit prepares the organization to better manage the meal to come. This timing plays a key role in the modulation of insulin and the mobilization of fats.
Its effect would be particularly interesting at noon or in the evening, when the metabolism is slower. But it is not a miracle fat burner: its action is part of a global lifestyle.
An essential precaution
Be careful however: grapefruit is known for its drug interactions. It can modify the absorption of certain active molecules, in particular statins, anxiolytics or treatments against hypertension. In the event of treatment, medical advice is imperative Before making it a habit.
For others, it can easily integrate into food, without doing too much. A half-price, on an empty stomach or before a meal, is more than enough. It can be consumed in neighborhoods or in a hurry, depending on the preferences. It is this simple gesture, repeated at the right time, which showed its effects in the clinical study. Measured, reproducible results, which recall that a simple fruit, taken at the right time, can have a real metabolic impact.
