I am obese. I don't eat chocolate. So the answer is "no".
The solution to obesity is to turn off the central heating (you burn about 1800 kCal per day to maintain body temperature in a 15 degree ambient, more at lower temperatures or with wind chill) and eat less of everything. Why do people mess about with complicated chemistry when the answer is simple physics?

I am obese.
I think the answer is in your response. You didn't become obese by eating air... Chocolate is one thing and yes you may eschew it, but there are other foodstuffs that clearly you do consume that are similarly over-stuffed with calories. Cutting the energy density of some of those foods might help you and others like you.
People could go for a walk and burn 400 kCal/hr, but they don't. Nor will they sit at home and shiver. It's human nature.

That's 470 watts. The highest continuous useful output recorded for a human was Bryan Allen, the Kremer Prize manpowered aircraft pilot, a professional cyclist who could sustain 300W for an hour. Farm workers and navvies can manage about 75W continuous for a 4-hour shift, which is why we use tractors.
Most of the energy loss in walking is thermal. Crosscountry skiing for 6 hours without a hat, at -10 deg C, I burn at least 6000 kCal per day, but walking the same track in summer, less than 2500. A good friend who was caught in an Alpine snowstorm roped himself to the mountain for 2 days, ate 12000 kCal of emergency rations, and lost 2 kg weight (mostly by evaporation). He then completed the climb, fell over in the icy car park, and broke a leg. Hubris.
The only things that will kill you are not enough of what you need, or too much of what you like. I woldn't recommend either to a youngster, but it was an easy choice for a 72-year-old ex prop forward who played his last game of rugby on his 60th birthday. Nevertheless it would be nice to wear Speedos again without embarrassment, so who knows?
