I have a twin who has always been chubby. He wasn’t very good as sports, and tends to gorge. The question really is how recent a phenomenon is obesity, and how culturally relevant is it? Are we evolving genetically towards an over-weight predisposition, or is there a more basic shift in life style? Everything seems to point to the latter. Exercise has become something you ‘should’ do, as opposed to being part of what one ordinarily does. Food is plentiful, cheap and full of fat and sugar. The food industry is very much to blame, as is government for not combatting the practices. Apparently, we are genetically geared to store fat for lean times when food is plentiful, and that gene has not been turned off from our hunter-gatherer days. Maybe, but obesity is more prevalent where the fast food industry is present. One day fries will carry a government health warning.
