If counting calories worked wouldn't people be thinner for knowing the calorie counts of everything? I never count calories or fat grams or worry about if I'm eating "right", as if a magic formula would suddenly turn me into a princess.
Wait - there is a formula. Whole foods eating in moderate amounts and getting plenty of variety and knowing how the individual foods work in the body to make the best choices at any moment.
But most people don't want to do that. They want to spend a lot of time and money on shakes, bars, goo and other things to enhance their workouts. I don't see that working out too well. Usually it creates someone eating more than they would normally. Thus, they get bigger. Plus those bars and shakes metabolize differently from unprocessed or less processed foods and create more acidity and puffiness.
Where are you getting your mis-information from? I suspect advertising or well meaning articles designed to push products or at least make an advertiser very happy. If they keep you hooked on products there is more profit than telling you to eat some whole grain in the morning to sustain you. You will never have the same energy from grapenuts as you would eating whole barley and you lose most of a grains health benefits when it gets ground up into flour and oxidizes before it ever gets made into something. Treats are treats and should be a small part of the diet. Unfortunately treat foods have crept in to being what most people try to live on. Then worry about weight, energy and health problems.
Let go of your worry, and slip into your ideal size by just learning how to eat healthy and whole. You'll never have to think about your weight much ever again.
