"People who are geneuinely obese who don't have significant issuees arounf self-esteem and a very odd relationship with food are rarer than hen's teeth"
I used to think this. But then I married into a fat family 10 years ago (MIL was obese now overweight, FIL obese, SIL1 overweight, SIL2 obese, 3 obese nephews/neices, 4 overweight nephews/neices), and it's been really fascinating for me to see how their food culture impacts on their eating habits and weight.
My husband's family are almost all oveweight, not because they eat junk food or because they binge - they're all great cooks, but because they simply eat huge portions of food all the time. They don't know what a normal, healthy portion of food looks like, and they serve the children and elderly members of the family the same sized portions as the teenage boys.
DH and I have got our heads round this whole portion control thingy at home now and we're very careful about how much we're eating. However, when we have extended family barbecues/meals my husband always slips back into his old ways and prepares 10 times as much food as anyone should be eating - and it all goes. I tell him 'The children don't need to have 4 sausages, two burgers, a couple of pieces of chicken and a portion of lasagna each (I kid you not), but he's frightened of looking mean and inhospitable so he ignores me. I sit there and cringe as I watch my SIL pile food onto her dads plate in huge mountains - my FIL who at 76 has had a stroke because of his hypertension and obesity - weighs 18 stone, can hardly get up the stairs or in and out of his chair......
Interestingly they're all really fatalistic about health - they say 'you could get run over by a bus tomorrow' or 'do you remember aunty Flo - smoked until her death at 90'. That doesn't help. I don't think this helps.
I honestly thnk the only thing that would change them would be to have someone lurking in their kitchen 12 hours a day policing their portion sizes.
And also to have a paediatrician sit down with my SIL's and point out to them that it's not healthy or normal for their children to have huge cellulity, wobbly guts hanging over the tops of their trousers! You'd think intelligent women would be able to see that their children are hugely FAT (not just big, but FAT) and know that this isn't good for them, but no - they talk with pride about how 'big' their children are, how the 13 year old is wearing an adult size 16 and the 10 year old is in a Marks and Spencer adult size 12 trousers because none of the waistbands will do up on the age appropriate clothes they pick out.
