If you eat less, even if you're of normal weight, you'll live longer, many researchers conclude from studies on monkeys and other animals. Now, as Rick and I discuss on PodMed this week, a study in JAMA Internal Medicine demonstrates that calorie restriction improves a number of other quality of life factors, and Rick reveals he's already adopted the behavior! What gives?
This study, known by the acronym CALERIE 2, randomized 220 men and women with a normal BMI to 2 years of 25% calorie reduction or consumption per usual. Outcome measures utilizing self-administered questionnaires included mood, depression, quality of life, perceived stress, sleep quality and sexual function. At the end of two years, compared with the consumption as usual group, the calorie restricted group reported better mood, reduced tension, improved general health, improved sex drive and relationship, and improved sleep! There was a positive correlation with greater weight loss. Well. Seems like even if you don't live longer you'll live better by voluntarily restricting your food intake, and as Rick quips in the podcast, so will your partner. Or should I say pardner. And we also discuss previous research that demonstrates decreased inflammatory markers, so sounds like such a choice may be a win-win.
Other topics this week include obesity trends and USPSTF recommendations for syphilis screening in JAMA, and a look at the Mediterranean diet, weight gain and fat distribution in the Lancet. Until next week, y'all live well.
