Many people think that low fat foods are the best way to go when trying to drop body fat. While I'm not necessarily saying that's wrong it's not always right either. If you compare a product that has a low fat version and a normal version the majority of the time, the lower fat option has more sugar in it to add the taste. As I explained earlier in the week, calories are important and it's a good idea to have a good idea how many you are eating. So if the low fat option has the same amount of calories because it has more sugar; is it any better for you?
Fat doesn't make you fat, eating more calories than you are burning over a period of time makes you fat, so it's always worth checking the nutritional information and comparing it to the non low fat option to see what the difference in calories and macros are. Pick the best option for you and not the option the retailers & clever marketing campaigns want to make you believe is the right one. The latter is usually the one that costs the most
