Green coffee: can it help you lose weight?
The new star of fast food, this unroasted coffee is found in pills or in supplement form. But does green coffee deserve its reputation as a weight loss stimulant? our expertise.
One slimming product expels the other! After green tea, it's green coffee's turn to be in the spotlight. What is it about? Simply unroasted coffee, hence the green color of its beans! The advantage: Green coffee is deprived of a roasting process that modifies the composition of the beans, retaining a higher content of polyphenols (antioxidants), caffeine and especially chlorogenic acid, and this compound, according to a fairly remote study, would dissolve fats.
In fact, the starting point for the popularity of green coffee goes back to 2006 when a Japanese team published, in the Annals of Internal Medicine, a study citing the advantages of overweight people. We already know that caffeine promotes spare fat burning (...provided you get physically active after
consuming it!) and that it also helps increase metabolism by making the body consume fewer calories. But in the case of green coffee, the focus is on another chemical compound: chlorogenic acid, which is also found in sunflower seeds, artichokes, chicory ... and even in potatoes, which do not have a good reputation for losing weight!
Green coffee: what do the studies say?
Several studies have shown that chlorogenic acid makes it possible to lose weight and prevent some of the harmful effects of obesity. To summarize the pharmacological action: Weight gain is mainly due to insulin resistance and fat accumulation in the liver. Thanks to its effect on the production of cynarin,
chlorogenic acid reduces insulin resistance and thus allows less fat accumulation in the body. Seranine is the main component that makes it possible to use sugars without converting them into fats. Thus, thanks to green coffee, dietary sugars are no longer stored as fat mass, but are immediately used by cells.
Green coffee: active ingredients for "slimming", yes, but ...
However, can we trust these studies? According to Raphael Grumman, Nutritionist*: “There are many active ingredients in green coffee that reduce insulin resistance and thus limit the absorption of sugars in the form of fat. But (yes, because there is a big effect BUT!), this effect remains very limited. In With supplements, the effect is a little bit bigger because the dose is higher, but it's still not very effective in controlling weight.”
Green...or Black Coffee: Beware of Excess Caffeine!
"Whether it's green or black, we must remain vigilant because excessive coffee consumption can lead to the risk of caffeine overdose which can cause tachycardia (rapid heart rate) or sleep cycle disturbances," warns Raphael Grumman. If you are taking green coffee extracts in the form of capsules, capsules, etc.,
do not exceed the prescribed dosage and duration of treatment. Do not combine with other dietary supplements or drinks that contain a "slimming" or "toning" substance (green tea, yerba mate, guarana, cola) that also contain caffeine. And of course abstain if you are pregnant, breastfeeding or have heart problems.
