80/20 can be quite doable. Like most thing diet related it comes down to consistency and discipline. I am in my 60's and weigh in the 190's and am 5'6" and get the occasional compliment. When i was in grade school and much shorter and laid around reading i weighed the same as i do now but obviously the proportions were much different. A person just has to figure out what is worth it to them. I suggest 80/20 for many unless they want 90/10 if they want health or leanness to be their real goal. 100% healthy would be for the very rare person. And i find most BB diets are not about health but about size. Living life is my goal. Looking good is 1 aspect. So is eating good food. I weighed and measured my food for years but don't any more. I just guesstimate. And adjust as needed. Just came back from a road trip down the coast for a week and lost 4 pounds. But that will come back i am sure. One of my goals recently has been to find exceptional bakeries. Found a couple this trip. But should have he evidence done shortly.
