> Most government guidelines indicated that, as a man, he needed 2,500 calories a day to maintain his weight (the target for women is 2,000)
Those guidelines alone are a recipe for rampant morbid obesity, and most people eat far more than that as evidenced by the rapidly expanding obesity rate. The majority of people are simply far too sedentary to recommend anywhere near that level of caloric intake, given the levels of obesity they could easily cut those guidelines by a third if not in half. Or even less if they wanted to promote cures to obesity related disease like type-2 diabetes.
By the way, eating about 800 calories a day will cause weight loss (not surprising, laws of physics still apply) and reverse type-2 diabetes.

Oh well, let the science denial continue. Whether it is weight and obesity, evolution, climate, pollution, biological sex, evolution, flat earth, creationism, in the modern era facts no longer matter.
