For weightloss _diet and exercise_ is the way to go: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4429709/.

>Prospective studies, however, find little evidence of the more physically active members of a population gaining less excess weight than those who are the least physically active.

>TEE adjusted for weight and age or PAL did not differ significantly between developing and industrialized countries, which calls into question the role of energy expenditure in the cause of obesity at the population level.
Citing a bunch of studies about obesity changes nothing about the fact that _exercise_ is more important to health outcomes than _weight_.

> There was no significant trend across BMI categories for mortality after adjustment for fitness.
Being skinny isn't being healthy, being _fit_ is being healthy.
This is pretty funny. They directly address and contradict the point your trying to make. Even the source you posted contradicts what you are trying to argue. Nice try though
This is bad advice, it's been shown over and over again that in the long term people don't manage to lose weight by exercising. They give up, don't exercise enough, overestimate how many calories they burnt, over-compensate by eating more and/or unhealthier ('because I earned it after taking a run'), etc.
You don't have to 'diet' to lose weight, just try to eat a little less each day, and watch what you are eating. Only 100 calories less than what you need each day, and you'll steadily lose maybe ~3KG a year.
