About a month ago I watched one of those "My 600 lbs Life" shows on the Discovery Network. If it wasn't that exact show than it was one just like it.
It featured two young British women who were mildly obese, maybe in the 240 lbs range. They sent them to Mississippi to live for a week with three Black Women, two sisters and their Aunt. The husbands were all long dead.
They were super obese, 400 to 500 lbs. I think the idea was a kind of "scared straight" thing. Give the young women a glimpse of their future if they keep getting fatter. The three Super obese women all had various health problems, diabetes with neuropathy
( numbness in legs) swelling, high blood pressure, failing eye sight etc. Plus it was very hard for them to get around. The Aunt who was slightly less obese would come around and drive them as needed.
They ate a classic Southern Diet with lots of fatty foods. Pigs Feet in Collards, bacon, Chitlins etc. They also ate lots of sugar and potatoes. Pies, breads, corn bread, canned fruit in heavy syrup etc.
The two British Women were suitably appalled. Near the end of the week they decided to cook a "Healthy meal" for them with the hope of getting them on a better track. What they thought was "Healthy " was lots of low fat dishes.
The three super obese women were polite about it "Oh this one aint too bad"..
There is no possibility of those three going on a Low Fat Diet. None... Zero.. This advice is likely to kill them as there is now no alternative that they know about.
I would have said to them, eat all the pigs feet and collards and bacon and beef that you want. Eat until you are full, just put down the pies and canned fruit and no potatoes or bread..but dont worry about the fatty food. Eat all you want. Eat until you are full and when you get hungry eat again.
I think that would have given them a shot. Bad science kills sometimes.
In the final scene they showed the two younger women back in London, highly motivated and jogging every day... Another doomed plan which I bet ended in failure.
