anyone watching Fat Family Tree (UK TV)?

Genetic influences

To date, more than 400 different genes have been implicated in the development of overweight or obesity, although only a handful appear to be major players. Genes contribute to obesity in many ways, by affecting appetite, satiety (the sense of fullness), metabolism, food cravings, body-fat distribution, and the tendency to use eating as a way to cope with stress.

A 2006 report in Science that studied more than 900 people showed that those who have two copies of a specific gene variant (called Insig-2) were 22% more likely to have a BMI higher than 30. Researchers believe the gene variant affects the regulation of another gene involved in fat production. In follow-up studies of more than 9,000 people (including people with Western European ancestry, African Americans, and children), they found that about 10% carried two copies of the gene variant.

In another 2006 study, published in the Proceedings of the National Academy of Sciences, researchers studied the activity levels of three different genes in fat samples from people who were normal weight, overweight, or obese. They took fat samples from around the participants’ internal organs and under their skin and found different levels of activity (known as gene expression) in the different samples. In overweight people, increased expression of two of the genes correlated with a tendency to be “apple-shaped.” These and related studies have helped researchers better understand how and why obesity occurs. They may also spur the development of new weight-loss treatments.

The strength of the genetic influence on weight disorders varies quite a bit from person to person. Research suggests that for some people, genes account for just 25% of the predisposition to be overweight, while for others the genetic influence is as high as 70% to 80%. Having a rough idea of how large a role genes play in your weight may be helpful in terms of treating your weight problems.

was interesting. Couple of experiments done on groups - one showed how drinking fruit juice as opposed to eating the same calories as fruit resulted in a 300 calorie extra intake at the subsequent breakfast.

Missed the first bit about genetics. One of the women was diagnosed Type II diabetic and the eating plan reversed that with her weight loss.

oh no I forgot it was on!!!!!

Hoping to watch it later.

I was gonna watch it but then by the looks of the women on it, they were clearly not trying everything to lose weight as stated on the ad, or not consistently.

Yes, there was a documentary ages ago which had a segment on very small children, showing that they did fall into two groups - one group would stop eating when they'd had enough, and the other group didn't (if it was food they liked). I don't remember whether that tendency turned out to be genetic or not, but I think identical twins often end up the same size (even in different environments).

oh, yeh, they ate 3 pounds of butter a week. thats one pound each. thats fricken amazing.

"i just dont understand it" - bites into a stick of butter.
