We are all different, and we should all just listen to our own bodies. In the past, I never wanted to eat much in the morning, just toast and coffee. But I am a Type 2 diabetic now, and have discovered that it is best for me to eat a little more substantially in the morning. Amazingly, it has been much easier for me to lose weight and control it by doing this. Because I eat more at breakfast, I only eat a small "snack" for lunch and a moderate dinner. And of course I am working out in some way each and every day.
I don't believe or trust any government studies, or even "Dr. Oz" or Dr. Mercola" or any of those other self-appointed gurus. There is just too much BS out there on the internet, TV and magazines, news. etc. I believe in only myself.
