 We’ve all heard why eating non-organic animal products is a bad idea: the animals may be raised in poor conditions, industrial agriculture produces large amounts of air and water pollution, it’s a leading cause of deforestation in the U.S., and the animals may be fed antibiotics.

 In my last blog entry, I highlighted how the high fat/low carb Inuit diet could counter-intuitively be healthy for its adherents. One of my students read the article and asked me if I knew anything about the (also) high-fat, low-carb ketogenic diet. Sometimes used as a treatment for pediatric epilepsy, the diet has also become increasingly popular not just for weight loss, but to change body composition - that is, to increase muscle mass and decrease body fat percentage. The student asked me if the ketogenic diet could do that in a safe way for a young person like him.
 It’s hard to go too long in today’s 24-hour news cycle without seeing headlines announcing the “latest scientific report” on weight loss, fad diets, or why the health trend of the moment is the best thing you never knew about. And as exciting as many of these news reports seem at first, these research headlines are often a sugar-coated version of the real story. And the outcomes of these studies may not even be the most important part.
 When we hear about childhood obesity, a few main factors get the majority of our attention: quality and quantity of food eaten, levels of physical activity obtained and total screen time consumed, to name a few. While these factors undoubtedly influence the development of childhood obesity, there are other variables that might also play a role. If we are thinking about how the quality and quantity of food a child consumes might lead to obesity, we should also consider how parents affect how a child approaches food. Evidence suggests that there is an association between restrictive feeding practices by parents and both overeating and weight gain in children.
 I recently participated in a ‘debate’ about whether we should routinely weigh pregnant women. The debate, which I thought would make interesting fodder for this blog, was just published in the June 2015 edition of the British Journal of Obstetrics and Gynecology. I’ll try to get permission to also post the other side, “Routine weighing does not solve the problem of obesity in pregnancy”, which is currently behind a paywall.
Gestational weight gain (GWG) outside of recommended ranges is a common and growing public health challenge. Since 2000, the percent of US women gaining weight during pregnancy in excess of current guidelines increased 3% – from an already high 42.5% in 2000-1 to 45.5% in 2008-9. In combination with the ~20% of women with inadequate gain, almost 2/3 of women are now gaining outside of recommended ranges. |
