is genuinely down to consumption of calories and nothing else
If we are going to over simplify; calories in(+), plus calories out(-) equals body weight. If all the fat people would just eat less they would all be fine.
Just have to disagree with you about being overweight can be the result of genetics, medical conditions etc
I don't agree at all. Is it an excuse? No. But genetics and medical conditions have an effect. I have hypothyroidism, which slows my metabolism. My family all has a tendency of being over weight. I also have been fighting with arthritis in both knees since 16, and a reoccuring shoulder problem since 18.
I eat healthy, probably 95% vegetarian, tons of fruits and veggies, only lean proteins, limited carbs, avoid wheat, dairy, sugar and anything processed. I eat about 1200 calories a day. I ride 2 days a week(4 days a week in the summer, fast rides of 10+ miles), bike, hike, walk, jog, kayak and do yoga. Some form of excercise an hour + per day. I'm over weight.
My cousin has a fast metabolism, a family prodisposed to be thin and no arthritis. She is 100#, eats 1800 calories a day and excercises the same amount.
If genetics and health problems have nothing to do with weight, then do explain the difference between my cousin and I.
