> I hear this and other fad internet diet stuff all the time

I've been eating a lower carb diet with portion control for more than 10 years now with little to no exercise. I recently changed into a low carb diet. Over this 10 year period I lost 30% of my body weight.

The only fad I've seen so far is the notion that practicing willpower and portion control while still eating sugar and carbs is a maintainable position.

Best of luck to you. But as others have noted, the rampant obesity in today's society is a recent problem - not something that happened in previous generations. What's different?

The vast majority of people no longer do manual labor for a living. And food used to cost a lot more. It's also possible that anti-smoking campaigns have had an effect since nicotine is a stimulant (which can suppress appetite) and reduces your sense of taste (making food less appealing), but that's probably a stretch.

There seems to be something else going on in addition to what you've mentioned.

I agree with all of your points. But there is more going on here.

Take a look at the top 5 strongest men in the world. They spend their days working out and probably burn more calories in a day than I do in a week. They have big, strong muscles that are covered over by a layer of fat. Same is true of many manual laborers today - landscapers, roofers, builders.

Compare that to body builders (work out, eat lower carb/sugar) or concentration camp prisoners who are underfed (whether they do labor or are almost entirely sedentary).

Comparing the groups (and my own experience) convinced me that eating (rather than exercise) is >80% of how much fat you will carry.

I'd say one of the biggest differences today is that sugar and carbs have become well accepted highly addictive drugs in our society. Feeling down? Go treat yourself to some ice cream! Is it any different with nicotine or heroin addicts?

I look at obese people in the same way that I look at nicotine or heroin addicts. It's not their fault, they're just normal people who are unfortunately caught in the tractor beam of addictive substances and they may not even know it. I didn't know it when I was a carbaholic. I thought I was fine -- didn't really connect my hangry episodes with withdrawal symptoms.
