Education is the answer I believe, but even with that the individual has to want to change. I’m testament to that, I’m reasonably educated (some may question that ) I’ve been involved in child care/education/health all my working life(40+ years) but still I’ve struggled with my weight. It’s the old nature versus nurture argument. I honestly don’t buy into the big boned arguments I’m afraid, yes some people’s bones if measured/weighed without flesh would be bigger and or heavier, but it’s the fat around them and bodily organs etc that is the issue. The only way to not be obese or overweight is to reduce that fat. I’ve finally done it after trying to lose weight all my adult life and part of my adolescence. So how you may ask, by cutting down on fats & sugars and wanting to is the only answer I can give. I’m now a healthy weight, my BMI is in the healthy range, but BMI is not always the way to go, there are lots of proviso’s of using that as a bench mark.
