@noblehead I hope I don't misunderstand you? Are you saying that lack of exercise IS to blame for obesity?
If so how would you explain the experience of people from Tokelau who emigrated to New Zealand from their tropical island paradise(?) in the 60-80s (I think) who rapidly gained weigh and became obese, got diabetes and heart problems.
In Tokelau their basic diet was fish and coconut and apart from occasionally having to climb a tree - if there weren't any on the ground they were a pretty laid back lot. However, when they got to NZ, despite working very hard (hence lots of activity) the change in diet to refined carbs. sugar etc resulted in obesity and metabolic syndrome?
My reference for this is the Diet Delusion - Gary Taubes chapter 8
If obesity is caused by lack of exercise, even though you have to do a tremendous amount of exercise to burn off calories, then in a sense you are blaming people for their diabetes. I can't believe that someone with your obviously great experience thinks that.
What if it's the other way round? That whatever caused their diabetes, led to the positive feedback cycle of eating more carbs, more sugar, more insulin, less leptin, more adrenaline, more eating and so on. And of course I am sure you know that serotonin and other neurotransmitters become impaired leading to depression, and that the body goes into shutdown mode and so the person doesn't even feel like exercising!
I am fat and obese, I do have diabetes, I don't feel like exercising, but I try a bit
