Over the past 4 days there have been two IOM workshop meetings on obesity; here’s a brief update.
The first was last Thursday/Friday on developmental exposures and obesity (mostly nutrition), and the second was Monday/Tuesday on the environment and obesity (at NIEHS). The slides and presentations of these workshops will be posted online. I would recommend these talks, they were all very informative.
Exposures to a wide variety of environmental factors—from chemicals to lack of sleep to microbiome to inflammation to viruses to antibiotics to nutrition to famine to maternal BMI to hormones to paternal factors to beta cell hypersecretion to artificial sweeteners to fructose—are linked to a higher (or sometimes lower) risk of obesity later in life, especially if exposure occurs during development (or possibly during other vulnerable periods, such as puberty). Obesogens may make it harder to lose weight and easier to gain weight, increasing our susceptibility to obesity.
