I went on the “Prism” diet in 1997. I lost 55 lbs and got down to 190. I’m 6’1”.
A major part of the diet was to learn about the nutritional value as well as harmful effects of foods. One thing I learned was this: Diet kills far more americans than smoking.
The result was, that though I always looked at the cigarette area in stores as the “poison” section, I learned to look at the candy and donut section the same way.
I smoke so I eat very little to make up for it. I love fasting. Once you can go 24-48 hours without eating, you can do amazing things with weight loss/control. It helps that I have no appetite. Long story due other medical issues that had long lasting effects (15 years now)
I keep my weight down. That extra health benefit allows me to smoke and drink more.
I know it shouldn’t be that way but I’m human. My wife can eat everything and stay as slim as she was at 20. She does work out. We have 2 very different approaches. Won’t matter she will out live me. She is 11 years younger.
