You've read the statistics: More than one-third of all American adults are obese, as are 17% of all children and adolescents—triple the rate of one generation ago. Obesity contributes to some of the leading causes of preventable death, including Type 2 diabetes, hypertension, heart disease, stroke, and certain types of cancer. Losing weight could improve your health, and you've resolved to do something about it.
But let's face it: it's easier said than done. And with all the conflicting information available, how do you know where to start? Is fat good or bad? What does "obesity," or even "food," really mean? What other factors are at play besides nutrition? From microscopic nutrients to global health initiatives, the Academy here presents some of the most recent scientific findings on health and obesity to help you understand the smorgasbord of factors that affect your waistline, including food, fat, chemistry, society, disease—even where you live.
Food and Physiology
A Thought for Food

Stemming from a lecture series at the National Institute of Diabetes and Digestive Kidney Diseases, this Annals volume presents a series of up-to-date reviews that evaluate the role played by the brain in body weight regulation. Free online access.
Energy balance over the lifespan varies within a narrow range in most people, yet it reflects a constant competition between energy-storing and energy-using processes. Concomitantly the conflict between autonomic/metabolic and cognitive/behavioral processes renders us physiologically maladaptive. This maladaptation is embodied in the chronic overnutrition syndrome, obesity.
What and How We Eat
Explore the origins of the ingredients in some of your favorite guilty pleasure foods, specifically the ones filled with processed ingredients. You'll find out just where those ingredients come from and how they made their way into your diet.
New York University food guru Marion Nestle gives a lesson in decoding food labels, holding big food corporations accountable, and choosing food wisely.
Take a historical look at our understanding of food and its effect on the body through the branch of Western medicine known as dietetics, which focused on maintaining and restoring health through regimen, hygiene, balance, and moderation.
Physical and Social Factors
A lack of walkable streets at home and an unparalleled reliance on car commutes may be keeping the U.S. overweight. Join a panel of scientists, urban planners, and fitness experts for a talk on how designing and building better cities and towns may make us a healthier—and leaner—nation.
The connections of physical and nutritional factors with health and disease, with special attention to the deleterious effects of metabolic dysregulation and obesity as potential mechanisms that amplify the development and proliferation of cancer. Free online access.
Far from being an individual problem, childhood obesity occurs in the context of a social landscape awash in high-calorie, low-nutrition food, especially for poor populations.
All About Fat
The origin of Brown Adipose Tissue (BAT), which is associated with diet-induced obesity and the effects of aging; how White Adipose Tissue (WAT) may be converted into BAT-like tissue; and how to enable the pursuit of BAT as a therapeutic target.
Contrary to the popular understanding that fat is bad, advances over the past several decades have enhanced our understanding of the functional necessities of fat and fat tissue as a key regulator of energy balance and intermediary metabolism and even as a part of appetite regulation.
Obesity, Disease, and Public Health
What is obesity, and what are its global implications? Our panel of public health experts discuss everything from current scientific understandings of overweight and obesity to the clinical, economic, and health policy initiatives that might help to stem the tide of this dangerous epidemic.
You've heard it once, you've heard it a thousand times: the U.S. has a big problem with obesity. But did you know that there are demonstrated links between obesity and all kinds of serious health problems—including cancer?
Includes reviews on central nervous system control of glucose and energy metabolism; circadian disruption and metabolic dysfunction; metabolic syndrome, adipokines, and dementia; and prioritization of care in adults with diabetes and co-existing chronic conditions. Free online access.
What characteristics of obesity lead to diabetes, and how are obese individuals who develop diabetes different from those who do not? Learn how metabolomic, genomic, proteomic, lipidomic, and other 'omic data can be integrated to shed light on the changes in metabolism that occur in obesity and diabetes.
