I learned as a 7 year old that starting sentences with "And" and "But" makes you sound like an idiot, although I suppose not all of us did. CICO controls your weight, nutrition and excercise controls your body composition. We use CICO to tell people in simple terms how to control their WEIGHT which is only one aspect of health, but absolutely one of the most important and easiest to fix.  Everything else about nutrition is secondary until you control your caloric intake, cause if you can't understand not to shove shit in your gob all day how can we expect you to understand anything else?
