Completely agree with that last paragraph and agree that countries with benefit systems enable obesity so much more than those without. Got a health problem caused by obesity? No problem the NHS will sort it with free advice and meds. Too fat to work? No problem here's disability allowance so you don't have to do anything to even sustain the mess you've got yourself in. I run around 70-90 miles a week, I don't shy from the occasional treat but with a tax like this I can see it hurting those who buy such things infrequently rather than those who will buy it no matter what. I'm paying taxes to provide these people healthcare, now they want to make me pay more  to "prevent" them buying things that any normal person can moderate themselves with; it's ridiculous.
