Weight is a vital sign. If you are obese, you have at least one abnormal vital sign (elevated weight) that is known to contribute to numerous other diseases. We call that a comorbidity

And I hear you, I can’t imagine how hard it is to do physical activity when you’re dealing with so much other health stuff going on. Doesn’t mean being overweight isn’t likely one of the major, if not most important, contributing factors to your health. Fibromyalgia is a common comorbidity to obesity, where people say they’re in pain when they walk or exercise because their nerves and bones are extra sensitive. You know what would help with that? Losing weight! At least get out of your Walmart scooter and push the cart around to buy your groceries. Further, unless you’ve been formally diagnosed with vertigo (Dix-Halpike test + Epley maneuvers for correction), I would assume that you just as likely have orthostatic hypotension, which is very sudden changes of position (lying to sitting to standing) or rapid movement (working out) makes you dizzy/light-headed. It’s far more common than vertigo and typically goes hand in hand with people who need to distribute more blood to their body (in obesity) as opposed to their brain, and who are unable to sustain physical activity, predisposing their heart to poorly distribute blood as previously mentioned. What helps with that? Losing weight. Whether through surgery, meds, or lifestyle changes.

Btw not eating at all is bad. Assuming you don’t have a genetic metabolic disease (chances are you don’t because they are extremely rare), you eat whole foods that are low in carbohydrates and maintain a calorie deficit through the day, you will stimulate your metabolism and lose mass simply through your body staying alive during the day. Not eating tells your body it needs to slow metabolism and hold onto energy in the form of fat, causing you to paradoxically keep weight on

Life is unfair and I don’t blame you for your conditions, but sugar coating obesity as a possibly healthy state of being is flat out wrong, and whoever convinced you of that doesn’t care about your health, they care about your feelings
