Don't you think that it's WHAT you put in your body that matters. Now if i keep the red meat protein and fat out of my system, and eat lots of veggies, rice , beans, whole grains and moderate red wine (cleans the arteries right out, not so good for the liver in excess), along with unsaturated oils, moderate aged cheeses, and plenty of good old time herbs, and heavy on the fruit (the so called mediterranean diet) that this can be better than starving oneself. My italian side of the family, well they are all octogenarians or better, and my UK side of the family are all dead. This could be genetic, but from what we know about beta protein and plaques ,tangles , and blocked arteries, i' m just a bit sceptical about calorie reduction as my italian side are all a few pounds overweight and my UK side are all skinny rails. Just one person's opinion.
