“When you talk about” burning fat “, you talk about the oxidation of body fat; ventilation of Lipids in fatty acids To use them as a fuel, ”explains Bethan Crouse, performance nutritionist at the University of Loughborough. This is the process that must occur so that someone loses weight or goes through a “body reward”; lose fat and gain muscle.
Regular exercise can increase Oxidation of fat, says Crouse. (When we lead to a low -moderate intensity, fat provides the majority of fuel for the working muscles. As the intensity increases, this will move more towards carbohydrates.) However, it says: “There is not necessarily a food that burns fat.” For a fat oxidation food, consumption should “reproduce the effects of the exercise”.
Where does she think that the idea of green tea fat burns from there?
“Caffeine – which is in green tea – in relatively high doses, in certain circumstances, increased fat oxidation,” explains Crouse. He activates the combat or theft response, increasing the release of hormones such as adrenaline and noradrenaline which mobilize energy stores.

However, she says: “It's a very small quantity, and research is not great – it is certainly not something on which you would recommend counting if someone tries to change their body composition.”
This is particularly true since, even if we have in depth and oxidize a lot of fats, if we are in an excess energy and consume more calories than we spend, our body mass will not decrease. “You can absolutely burn fatty acids instead of carbohydrates, but do not lose body mass,” explains Crouse.
His advice for anyone trying to lose fat? Avoid falling in love with supervisors or supplements. “There are many big daring claims,” she says. Instead, increase the exercise and gently reduce the number of calories you consume.
