What do you think should be done about the obesity epidemic?

Stop promoting healthy at any weight, its a lie. Stop promoting fat acceptance. Stop with fatphobic bs. There is no such thing as fatphobia, they are not a marginalized group. If they wanna stay that way fine, but they should be encouraged to exercise and not dine out at mcdonalds for every meal.

1. Build dense, walkable cities with dedicated bike paths and trains so people can get around without cars.
2. Ban all advertising for all unhealthy foods, including storefront advertising and box art.
3. Establish public parks with opportunities for a wide variety of outdoor activities, as well as accessible public bathrooms. For the record, this is already being done.
4. Grant free preventative care and treatment to all citizens, including mental healthcare and dieticians. Obesity develops for a variety of reasons, in part because of unhealthy attitudes about food, which could be addressed through therapy.
5. Make a national effort to combat systemic work stress through pro-union and pro-co-op policies. Establish a PBI and universal housing system, which will together give workers more negotiating power, which they could use to bargain for lower workload.
6. Continue developing weight loss drugs, and ideally create one with such limited side effects so as to be suitable for use as an OTC medication.
7. Levy a tax on sugar which is high enough to motivate more stores and restaurants to offer low/no-sugar alternatives.

It’d help if the food industry would stop putting MSG (an appetite stimulant) in a great percentage of foods and other excitotoxins as well. It’s like drugging people to force feed them. And not healthy at all for the brain.

Nothing. People need to take responsibility for their own lives and decide what is right for them.

Obesity is often linked to poverty. The fact that a lot of high-fat, high-salt, high-sugar food is cheap and convenient means getting obese is easy for some. People also don't find enough to reason to get out of their home and be active.

I don't know what can be done about it but there are some factors here that I think could be addressed.

If "What should be done" refers to [u]political[/u] regulations then I think nothing should be done about it.
Most people have a choice. Almost nobody is obese as a result of bad fate.

Stop trying to make it seem attractive and acceptable! Calling rolls and overweight "curvy" to somehow justify it, is a load of crap. That is NOT curvy. It's delusion.

Send the obese to the dieticians and nutritionists. Let them deal with it. If an individual doesn’t want to lose weight then that’s on them.

nothing. If people want to eat themselves to a early grave, who am I to stop them?

Stop giving young children sugar in drinks and food, it’s addictive

Get cycling!
I know I am biased, but to be out cycling everywhere I go, has me appreciating so much more then being stuck in traffic and whining about others on the roads.

Keep munching.

In terms of children, healthy school lunches and P.E. classes should be provided, and I think that would help. We got outside and moved around, we didn’t spend the day sitting at computers. That would be a good start.

But for adults, possibly if gyms were free to those attempting to lose weight and if healthy foods were less expensive than fast food, those might be incentives, too.

But nobody should be forced, bullied or shamed. None of that is productive long term.

It's not something I think "we" have to deal with or solve. Personal problem/choice.
