In Switzerland, 6% of men and 5% of women are obese (BMI > 30); 33% of men and 17% of women are overweight (BMI 25-30). Both genetic and environmental factors are responsible for obesity. There is an increased risk of C-V disease, diabetes and steato-hepatitis in abdominal obesity (abdominal circumference > 102 cm for men and > 88 cm for women). There is also an increased level of cortisol, which could be due to a difficulty to cope with psycho-social stress. Leptine and different hormones play a role in fat storage. Menopause and pregnancy are moderate risk factors for obesity. Weight gain may also result from different drugs, smoking cessation and stress. Eating disorders such as boulimia and binge eating must be diagnosed and treated. Beneficial health effect of weight loss is analysed.

Abdominal obesity is prevalent and often accompanied by an array of metabolic perturbations including elevated blood pressure, dyslipidemia, impaired glucose tolerance or insulin resistance, a prothrombotic state, and a proinflammatory state, together referred to as the metabolic syndrome. The metabolic syndrome greatly increases coronary heart disease (CHD) risk. Social stress also increases CHD although the mechanisms through which this occurs are not completely understood. Chronic stress may result in sustained glucocorticoid production, which is thought to promote visceral obesity. Thus, one hypothesis is that social stress may cause visceral fat deposition and the metabolic syndrome, which, in turn increases CHD. CHD is caused by coronary artery atherosclerosis (CAA) and its sequelae. Cynomolgus monkeys (Macaca fascicularis) are a well-established models of CAA. Social subordination may be stressful to cynomolgus monkeys and result in hypercortisolemia and exacerbated CAA in females. Herein is reviewed a body of literature which suggests that social stress increases visceral fat deposition in cynomolgus monkeys, that subordinate females are more likely than dominants to have visceral obesity, that females with visceral obesity have behavioral and physiological characteristics consistent with a stressed state, and that females with high ratios of visceral to subcutaneous abdominal fat develop more CAA. While these relationships have been most extensively studied in cynomolgus macaques, obesity-related metabolic disturbances are also observed in other primate species. Taken together, these observations support the view that the current obesity epidemic is the result of a primate adaptation involving the coevolution with encephalization of elaborate physiological systems to protect against starvation and defend stored body fat in order to feed a large and metabolically demanding brain. Social stress may be engaging these same physiological systems, increasing the visceral deposition of fat and its sequelae, which increase CHD risk.

Many people eat unhealthy foods that are high in calories, fat, or sugar when feeling stressed, yet little is known about whether this unhealthy comfort eating actually comforts. Additionally, prior research has not tested whether healthy comfort eating of fruits and vegetables might also alleviate stress, or whether comfort eating during the stress anticipation phase versus immediately after a stressful event is more beneficial for stress relief. The present experiment tested whether unhealthy and healthy comfort eating reduce acute psychophysiological responses to a socially evaluative stressor. Participants (N = 150 healthy women) underwent the Trier Social Stress Test in the lab and were randomly assigned to one of five conditions according to a 2 (food type: unhealthy vs. healthy) x 2 (eating timing: during stress anticipation vs. after the stressor) + 1 (no food control) between-subjects design. Stress outcomes included mood, cognitive appraisals, rumination, salivary cortisol, heart rate variability, and pre-ejection period. Unhealthy and healthy comfort eating did not dampen reactivity or enhance recovery of psychophysiological stress compared to control, and no differences in reactivity or recovery were found by comfort food type. Findings suggest that by replacing unhealthy comfort foods with fruits and vegetables, women will not be sacrificing any stress-reducing benefits and can inherently improve the quality of their diet while avoiding potential drawbacks of unhealthy comfort eating (e.g., links with abdominal obesity).
