I dropped from 195 to 162 at 6' after I retired. I credit a small amount of that to reduction in stress and regular riding but most to cutting out the massive amounts of sugar and highly refined carbs I used to eat. I have slowly added back potatoes, rice, and the occasional pizza and pasta with no ill effect. For me I think sugar is the real danger. Never again will I regualrly eat half a pound of delicious milk chocolate at a sitting. But most of all I miss those double fudge brownies with coffee at breakfast.
