> Studies show it just doesn't work.

Eating less and exercising most certainly does work, if the individual sticks to the routine.

I do agree it's difficult to stick to a routine because our modern lives are demanding and so we compromise by eating fast food and avoid going to the gym.

I think the exercise paradox video recently put out by Kurzgesagt has been a net negative for how people think about diet and exercise. The paper the video is based on is highly flawed.

That paper has a few major problems but these are the biggest:

1) The authors didn't control for body mass. The Hadza and Bolivians burned 52kcal per kg of body weight. Americans burned only 38kcal per kg of body weight. That is: the active groups burned significantly more calories than the inactive groups, on a pound-for-pound basis.

2) The active groups were defined as such because they walked ~12km per day. This is significant because the human body is exceptionally efficient at walking. It is certainly true that over a comparable span of time, you will burn less calories walking than you would running, or lifting weights.

GLP-1's are miracle drugs and people should take them if they at are high risk for obesity-related diseases.

But diet and exercise certainly do aid weight loss, and will have fewer negative side effects than a GLP-1 drug.
