I will tell you what my doctor told me. "You know when you eating it, if it's bad or good for you." I cut out butter and mayonnaise almost completely, if I drink a soda, it's diet soda. I cut way back on the beer too, from about a case a week to about a 6 pack a month. Diet doesn't mean eating less, diet is what you eat. Some of us have a good diet, most of us have a bad diet, some of us eat until we are satisfied, most of us eat until we are stuffed. As hard as it is, it's actually quite simple, eat better, don't overeat, and exercise for health. Oh and BTW, I've lost almost 60 pounds since the first of the year following that simple plan.
