Study Proves Having Fat Friends Makes You Fat

Xemu writes "Having fat friends makes you fat, researchers from Harvard Medical School and the University of California says after after examining 12,067 individuals and 38,611 of their relatives and friends. In same-sex friendships, people were 71 per cent more likely to put on weight if a friend of theirs became obese. "It's not that obese or non-obese people simply find other similar people to hang out with. Rather, there is a direct, causal relationship," says Harvard professor Nicholas Christakis."

Oddly enough, obesity seems to be mostly a disease of first world societies. Could it be that human evolved to live in an environment of scarcity and that in 2-3 generations we haven't yet managed to rewire ourselves to adjust to living in an environment of plenty.

No, the U.S. has been mostly a nation of plenty for a couple hundred years or more. Depending on how you count, that's easily 6-8 generations. Mass obesity has only come in the last generation or so. Most people are obese not because of genetics, laziness, or overconsumption. Most people are obese because for years we've been taught to eat incorrectly and because the quality of our food has taken a substantial decline.

If the obesity problem were simply a result of us not being used to availability of food, we would have seen nearly constant levels of obesity for the past two or three generations. Instead, we're seeing an order of magnitude increase in morbid obesity (>40% BMI) since the mid 1980s. We weren't all struggling to find food in the mid 1980s. If this study were done in the 1950s comparing against the 1930s (Great Depression), I might believe that explanation, but it just doesn't make sense in this day and age.

In reality, the mass obesity problem coincides perfectly with the rise of processed foods. This got worse after the U.S. government started giving huge corn subsidies and putting high import duties on sugar to encourage use of high fructose corn syrup. Fructose is processed by the body very quickly, but does not trigger the same insulin response as glucose. Thus, your body A. does not feel satiated, so you consume more, B. does not gain the metabolic surge that normally occurs in response to elevated insulin levels, and so does not use all that energy, C. stores the resulting excess energy as fat. Replacing that same amount of fructose with glucose will cause a significant weight loss.

Similarly, when your body consumes a large amount of food at once, it can't use it all immediately, so much of that energy gets stored. That's why consuming proteins are better for you than consuming sugars and starches from a weight perspective. Note: you should not eat all protein. You do need other stuff to prevent lots of colon problems later in life, and many sources of protein bring fat along for the ride, which is even worse than (at least complex) carbohydrates.

However, without changing what foods you eat at all, you can significantly reduce your weight by spreading it more evenly throughout the day. Fix yourself a normal lunch, but instead of eating the whole thing, put aside a third of it and consume it in mid-afternoon.

Case in point, I've tried exercise and diet with no success as all. However, I recently lost a substantial amount of weight while consuming substantially more calories than before. I replaced my usual HFCS-sweetened beverage at lunch with an entire extra meal later in the day, drinking only water and fruit juices. I'm guessing I now take in half again more calories, but I weigh ten or twelve pounds less (depending on the mood my digital scale is in) and have kept the weight off for a couple of months now.

Your mileage may vary, but it has been my experience that total calorie consumption is only a very small part of the obesity picture, and not the most important part by any means.

Oh, yeah, and don't get me started on diet sodas. They're even worse than HFCS-sweetened sodas at causing people to gain weight. (Source: University of Texas Health Science Center, San Antonio.) If you're overweight, switching from "diet" sodas to regular sodas might actually cause you to lose weight.... Talk about false advertising....

Depends on how fat they are. Skinny chicks aren't attractive to me. Better for the wrong parts to be a little too big than for the right parts to be too small.
