Go google hypothyroidism and PCOS. Then come back and tell us what you learn. I'll have crayons and paper so you can show the whole class.
Imagine that.
Where PCOS is associated with overweight or obesity, successful weight loss is the most effective method of restoring normal ovulation/menstruation, but many women find it very difficult to achieve and sustain significant weight loss. A scientific review in 2013 found similar decreases in weight and body composition and improvements in pregnancy rate, menstrual regularity, ovulation, hyperandrogenism, insulin resistance, lipids and quality of life to occur with weight loss independent of diet composition.[41] Still, a low GI diet, in which a significant part of total carbohydrates are obtained from fruit, vegetables and whole grain sources, has resulted in increased menstrual regularity than a macronutrient-matched healthy diet.[41] Vitamin D deficiency may play some role in the development of the metabolic syndrome, so treatment of any such deficiency is indicated.[42]
..... In other words, eat your veggies and don't be a pig. Medically speaking, of course.
I was a lard-ass like you, until I took a doughnut to the knee.
Overweight people are not spontaneously generating matter, sure, but it's not like people can just stop eating until they hit the weight you'd prefer them to have, they kinda stop working before that happens.

This takes me to Wikipedia

Wikipedia tells me this has little to do with "gobbling up everything in sight". Sadly, physics, biology and chemistry don't know what cause it (yet), nor is there a cure (yet).
Matter cannot be created nor destroyed. So, that means garbage in = fat + garbage out. You really are what you eat.
I know this by my own diet. When I gobbled up everything in sight, I <gasp> got fat. When I quit packing my face full of food, I lost weight. Interesting how that works.
