I had a patient not too long ago who struggled to lose weight. A quick look at her food journal revealed why. To save calories, she skipped breakfast and simply sipped on coffee or one of those "skinny lattes" that actually contain a good bit of sugar.
Eating upon waking brings your blood sugar levels back to normal, kick starts your metabolism, and sets you up to be on an even metabolic keel for the rest of the day. So break your fast every morning. It will make you healthier, give you more energy through the day, and help you lose weight.
