Converting carbs into fat is fairly inefficient. It comes at about a 40% calorie loss. So you can put on fat eating carbs alone but it’s not easy. More often than not we eat carbs together with fat so your body will very happily just directly store the fat and burn the carbs for energy.
This is why things like french fries or pizza are so fattening.
- amelius 8y agoBut if you eat just proteins and fat, the fat is not stored (see e.g. keto diet) How can this be explained?
- mrfusion 8y agoI’d guess it’s because in that case you don’t produce much insulin which is starting to be called the fat storage hormone.
- cageface 8y agoProtein also stimulates insulin release. You’ll get a bigger spike of insulin from eating a steak than a plate of spaghetti.
- latortuga 8y agoWhen you eat fat and carbs, the fat is stored and the carbs used for energy. When you subtract carbs, your body still needs energy so it starts using fat.
- cageface 8y agoYes it is: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5326984/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5326984/ There’s no magic in keto. People lose weight on keto because they wind up eating fewer calories, usually because they cut back on processed junk food as part of going keto.
