Sadly, likely genetic considering cholesterol is now genetically linked and only meds can dissolve it. That said, a lot of other things like survival of that *IS* diet linked, and those items, short of the donuts may cause gout, not not likely cause you to be fat. Sugar/carbs (simple, followed by complex in that order for easiness to convert to fat) is what causes obesity. Animal fat cannot convert to fat in out body. Not compatible, but sugar, past 5g without energy usage or improper metabolism, cannot be immediately used and gets converted to fat if not expelled, therefore most (not all) junk food, preprocessed food, etc… which rely on sugar for taste/addiction is the biggest culprit. While atkins was onto something, his was too extreme. The keto diet follows this theory, and I can say it works. I honestly resisted doing it years ago, but 2x used that to lose weight. But I didn’t give up beer and fruits/veggies. Quality of food matters more than quantity, but there’s a lot of misconceptions over fatty foods. Unless you just want gout. The increase in sugar in foods led to obesity and diabetes. We didn’t see this before preprocessed, easily addictive foods hit mass shelves, but don’t blame fat itself. That said, sorry OP. Your life sucks, but if you eat healthy, you will be able to survive things like heart attacks easier. Be careful on cholesterol meds. Yes, less cholesterol, but same for good cholesterol which you also need if you wish the SURVIVE the heart attack. So look into that first.
