My father gave up red meat and soda around 2002. My dad's clone, my uncle didn't give up anything. Yes they are clones, I sequenced them myself. Since then my dad has always been at least 20lbs heavier than my uncle despite having almost identical activity levels since they had similar jobs and shared hobbies for most of the time. Now 23 years later my dad has heart congestive heart failure and a torn meniscus in his knee while my uncle has a perfect heart but has needed both knees replaced. I think the biggest difference is definitely the sugar because my uncle tends to drink diet soda and my dad fruit juice, tea and coffee.
