I'm someone who is naturally fat. I have spent my whole life trying to lose weight. Many of you here have excluded fat people from your lives so you won't hear this from someone else: you are the weight you are due to factors outside of your control. You can slightly change your weight temporarily but your body will always reset or give you stress signals to reset it yourself. I know, I have starved myself, done incremental weight loss, worked out almost year round as a football player, it doesn't stay off and it barely comes off (10-20 pounds total is insignificant). Fat people shouldn't have to starve themselves to meet societal standards and personally I won't.
PS. The reason fat people don't like going to the doctor is because they quite literally will not treat us for our issues in most cases. I've been trying to get treatment for my crippling back pain for years and have been told by physical therapists not to do physical therapy until I'm on pain medication but even with this info doctors just tell me to exercise. I'd love to, in fact I'd love to take walks often but I physically cant.
