> highly effective

Purely behavioral lifestyle interventions have the lowest long term success rates of all available treatments for obesity. It's especially unreliable if you have weight loss targets higher than 15%.

They are of course still widely recommended due to numerous benefits other than weight loss, but "highly effective" is just wrong in the context of obesity treatments.

This problem literally did not exist until the 80s. I don't think the human brain/body evolved much since then so surely there is another problem. The only solution is behavioural, everything else is cope.

It's the same thing for the mental issues epidemic... you can't build a completely hostile environment to human life and well being and then say "welp, I guess we need drugs to make you feel normal now", now they'll sell us the drug and the cure, and you'll be clapping and thanking them for saving you, truly amazing.

Henry VIII might have a word for you on that one, as would many other of history’s aristocrats. The only thing that’s really changed is the cost of food that used to be reserved for kings.

What? Surely changing one's behaviour - particularly the parts of behaviour that caused the obesity in the first place - is a sure way to stop being obese.

By this reasoning, abstinence-only sex education is a sure way to stop teen pregnancies and spread of STDs.

Your analogy is false.

If you opt for it, then yes of course, abstinence-only sex education is a sure way to stop ten pregnancy.

Similarly, if you opt to change your lifestyle and start living healthier, and follow through, it will work.

If someone tries to force you, of course it will fail (in both of these cases). There is no way to stop someone else from being fat. We can only change ourselves.

The issue is not whether it works; it’s whether someone can stay compliant long enough for it to work

It's a lifestyle, the optimal basic lifestyle, the one were you don't shorten your life/healthspan by decades. It's how thing were intended to be really.

It's funny how proposing an healthy diet is unrealistic and watching fatties eat themselves to death is the new normal, complete value inversion and looser mentality

Long enough in this case meaning forever.

Behavioural changes work, the issue is that most people don't actually change their behaviour.
