Everyone talks about the best diets to burn fat, the best exercises to lose weight and be in shape, but does anyone know where the fat we burn when we lose weight goes? It turns out that it does not become energy, as many scientists even believed.
It is likely that there are more people who know diets to burn fat, than people who know where the fat goes when you burn it. And, even many scientists were wrong with what happens with fat when we lose weight.
15th health experts, from doctors, nutritionists and personal trainers answered a big question “where is the fat we burn”, but only three were right. Among the 98% of failures the most common response was that fat is converted into energy or heat, while others maintained that it becomes muscle.
However, the correct answer is that the fat that we lose turns into CO2 and water. This means that the weight you lose when exercising exits through your lungs, urine or sweat.
Let’s say you lose 10kg: 8.4kg would go through your lungs and the remaining 1.6kg would turn into water. This also happens with food; carbohydrates and most fats are converted to CO2 and water, while the same thing happens with protein, except for a small part that turns into urea and is expelled with urine.
But how is it possible that so many scientists have been wrong? “At school we all learn that ‘the energy that comes in is equivalent to energy that comes out’,” explain the study’s scientists, Ruben Meerman and Andrew Brown, in The Conversation. “But energy is a very confusing concept, even for health professionals and scientists who study obesity,” he adds.
Meerman and Brown also emphasize that the oxygen we inhale also makes the scale go up, with more weight being lost by our body each day. That yes, we must bear in mind that much of what you lose you do while you sleep, as we exhale 200 grams of CO2 at night.
This is when a great question arises for many: if we exhale more will lose more weight? The scientists answer categorically to this question: no.
