Keeping It Off
I found this NYT article yesterday about the difficulty of successful weight loss, and finally finished reading it today. I have been interested in this topic recently–the science behind weight loss. Partially I’m interested in this because there is increasing evidence that obesity has underlying biological factors that contribute to its epidemic; i.e. obesity is more like a disease, not a choice. The article is fairly long, but some of the more interesting points I found were the following:
1. There are hormonal changes after weight loss (lower peptide YY and leptin, higher ghrelin) that make it hard to keep the weight off (i.e. someone who used to weigh 150 pounds and now weighs 120 pounds, is different than someone who naturally weighs 120 pounds)
2. Some people have specific genes that make them more predisposed to eat higher calorie foods, and make it harder to lose and keep weight off
3. People who successfully keep weight off are the minority of those who try to lose weight, but they all have specific consistent habits, including tracking their food and exercise, weighing themselves daily, exercising daily, eating breakfast everyday, watching less TV, and not “cheating” on holidays and weekends
4. After weight loss, you are more susceptible to cravings than before (and this is shown on brain MRIs in research, and is some of the evidence behind obesity having similarities to addictions)
5. Knowing some of these things can help to improve ways of losing weight
Now after read this article I feel a bit more informed. It is easy to tell those who are obese to eat less and exercise more. While these tenets are still the core of achieving weight loss, we are starting to learn that not everyone has the ability or the genetics to do this things as effectively or efficiently. That being said, it’s not a reason to give. It may just be that we need to start approaching weight loss for people in a different light, for example slowing it down rather than speeding it up. Another reason to avoid those infomercials late at night!
Good luck and as always feel free to leave comments or feedback!
