Top 10 in Top 10 misunderstandings about nutrition.
Eat fat, increase fat? For decades, the traditional way to lose weight was to eat a low-fat diet, but current evidence suggests that, with the same caloric deficit and protein intake, a low-fat and low-carb diet are similar to the weight loss results.
Moreover, while a low-fat diet is not necessarily bad. Cutting out all types of fat from the diet is quite dangerous, because your body needs to consume a minimum of omega-3 and omega-6 fatty acids. As for the idea that saturated fat is the main cause of heart disease, that's just another misunderstanding.
After all, trans fat is the only fat that has been shown to be harmful to health - small amounts will not kill you, but it will be harmful in the long run.
Fact: If you are in a caloric surplus, a low-fat diet will not make you lose weight. You need omega-3 and omega-6 fatty acids. Saturated fat will not cause you a heart attack (but too much trans fat will be possible).
