The rest is pure hooey.
Why this obsession over what people eat, and all the nanny warnings? If someone wants to eat 1000’s of calories in the form of nutritionally useless carbs and sugar that turn right to fat on their ass, it is no one’s business-neither is it anyone else’s responsibility to fund their bariatric surgery and tummy tucks when they get to the point that they can’t stand the way they look and have barely enough energy to collapse onto the seat of a motorized cart at the grocery store.
The calorie thing is dependent on individual metabolism, size, etc as well as activity level-one size does not fit all. I am nearly 5’9”, 106-108-on a very small frame-I’m slightly muscular because I have a physical job and I work out with weights and resistance several times per week-I eat only organic, unprocessed veggies and meat, almost no carbs, no sugar-about 1100-1200 calories per day of protein and good things found in veggies and fresh fruit-this is the same way I’ve been eating all my life, and it works for me-it would not be enough food for a person my height with a larger frame, but it might keep a sedentary 5’9” female office worker with a small frame enough overweight to be thinking about starting the NutriSystem plan-those stupid food pyramids and calorie recommendations totally ignore the fact that humans are all individuals...
