Worldwide Obesity Dynamics and Their Determinants

Review of results of the study is focusing on large-scale surveys and nationally representative studies of diet, activity, and obesity among adults and children. The study was conducted with youth and adults from a range of countries around the world. Task Force guidelines for defining overweight and obesity are used for youth and the body […]

Neighborhoods and Obesity

This review critically summarizes the literature on neighborhood determinants of obesity and proposes a conceptual framework to guide future inquiry. Thirty-seven studies met all inclusion criteria and revealed that the influence of neighborhood-level factors appears mixed. Neighborhood-level measures of economic resources were associated with obesity in 15 studies, while the associations between neighborhood income inequality […]

Brain Evolution, the Determinates of Food Choice, and the Omnivore’s Dilemma

A coevolutionary paradigm using a biocultural perspective can help to unravel the complex interactions that led to the contemporary pattern of eating. Evolutionary history helps to understand the adaptation of diet and its nutritional implications. Anatomical and behavioral changes linked to changing dietary patterns in the Paleolithic resulted in an adaptive framework that affects modern […]

Obesity: From the Agricultural Revolution to the Contemporary Pediatric Epidemic

Obesity is pandemic in Western society. Currently, approximately 100 million Americans are overweight (body mass index > 25 kg/m2) or obese (body mass index > 30 kg/m2). The pandemic is largely attributable to the relatively recent (from an evolutionary perspective) adoption of a sedentary lifestyle, coupled with the high availability of foods with high caloric […]

Costs of Foraging Predispose Animals to Obesity-Related Mortality when Food Is Constantly Abundant.

Obesity is an important medical problem affecting humans and animals in the developed world, but the evolutionary origins of the behaviours that cause obesity are poorly understood. The potential role of occasional gluts of food in determining fat-storage strategies for avoiding mortality have been overlooked, even though animals experienced such conditions in the recent evolutionary […]

The Case for Dietary Fat

For decades, dietary advice was based on the premise that high intakes of fat cause obesity, diabetes, heart disease, and possibly cancer. Recently, evidence for the adverse metabolic effects of processed carbohydrate has led to a resurgence in interest in lower-carbohydrate and ketogenic diets with high fat content. However, some argue that the relative quantity […]

Effects of a Low Carbohydrate Diet on Energy Expenditure During Weight Loss Maintenancel

Objective  of the study was to determine the effects of diets varying in carbohydrate to fat ratio on total energy expenditure. The study was done with a multicenter collaboration at US two sites, August 2014 to May 2017.  164 adults aged 18-65 years with a body mass index of 25 or more participated to the study After 12% […]

The Carbohydrate-Insulin Model of Obesity: Beyond “Calories In, Calories Out”.

Despite intensive research, the causes of the obesity epidemic remain incompletely understood and conventional calorie-restricted diets continue to lack long-term efficacy. According to the carbohydrate-insulin model (CIM) of obesity, recent increases in the consumption of processed, high-glycemic-load carbohydrates produce hormonal changes that promote calorie deposition in adipose tissue, exacerbate hunger, and lower energy expenditure. Basic […]

Extra-Virgin Olive Oil Preserves Memory and Protects Brain Against Alzheimer’s

The Mediterranean diet, rich in plant-based foods, is associated with a variety of health benefits, including a lower incidence of dementia. Now, researchers at the Lewis Katz School of Medicine at Temple University (LKSOM) have identified a specific ingredient that protects against cognitive decline: extra-virgin olive oil, a major component of the Mediterranean diet. In […]

Emotional Eating Is Learned Not Inherited

Emotional over‐eating (EOE) and emotional under‐eating (EUE) are common behaviours that develop in early childhood and are hypothesised to play a role in weight status. Data from a British twin cohort demonstrated that environmental, rather than genetic, factors shape individual differences in both behaviours in early childhood. The aim of this current study was to […]
