I should by rights be the size of Primo Carnera for the huge dinners etc I've packed away in the past, with an appetite like that of a horse. But alas, my metabolism made sure that it would assimilate what I'd eaten and would keep me at a steady 9 and a half stone for life until this last 6 months or so when my weight has crept to 10 stone because of my semi-sedentary life. But I am 5' 7 so it's not so noticeable. BMI is 21.9, so within range.
Most of what I eat is from scratch and during winter months you tend to " bulk up " with stodge ( steak and kidney suet puds ) and stews and mashed potatoes.
My GGC are fed home cooked dinners and they're all slim, except their mother ( my GD ) as she had a thyroid problem a few years back and went to skin and bone, was put on medication and she's now quite big, but it was awful seeing her with her clothes hanging off her. She likes the odd pink gin too, but her treat.
Not all obese people have problems though as fat that has collected/been stored in their behinds stays there whereas in a slim person the fat in the body tends to settle around vital organs causing problems. A slim person can have a higher cholesterol reading than an obese person so are prone to type 2 diabetes and heart disease.
