Hunter and gatherer tribes don't count calories, yet they're not fat. Obesity took off in the 80s, yet availability of fast food wasn't suddenly forced upon us.

Exercise is healthy, but your metabolism adapt to the amount of exercise you do by adjusting its basal metabolism. It's not that great of a tool for weight loss, but you should do it for health. Anyway, I am speaking of this as a person who lost 32 lbs over the past four months without having to count a calories and who attempted to overcome basal metabolism adaptation by sheer high level of physical activities.
