To our knowledge, the current investigation is among the first studies in adults to evaluate the associations of PFAS exposures with changes in body weight and metabolic parameters induced during a controlled weight-loss trial. All individual PFASs were significantly associated with more weight regain in women, but not in men, which was in agreement with previous studies in which the intergenerational effects of PFASs on body weight were observed only in girls and not in boys [21,25,26]. Although the reasons for these gender-specific findings are still unclear, accumulating evidence from experimental research suggests that PFASs are able to interfere with estrogen metabolism and functionalities [12,50,51]. As potential endocrine disruptors, PFASs might reduce estradiol production and the expression of some key genes related to estrogen synthesis , or influence estradiol concentrations through pathways such as hepatic aromatase induction, with an initial inhibition and a later stimulation . Using in vitro and in silico species comparison approaches, Benninghoff et al. reported that PFASs may interact directly with estrogen receptors, suggesting that PFASs could act as weak environmental xenoestrogens . The experimental evidence implies that the detrimental effects of PFASs can be sex-specific, thus supporting the notion that women may be particularly vulnerable to obesogenic effects of PFASs. In addition, it is worth noticing that women generally have a higher percentage of body fat than men . Given that fat-free mass could substantially influence RMR, the difference in body composition between men and women could result in significant differences in energy homeostasis dynamics .
“It can be easy for people to focus merely on what they are eating and on the weight loss progress,” says Mast. But sustainable weight loss relies on other factors as well. Mast emphasizes that finding a supportive community or one-on-one health coach is invaluable. Without a positive support system or the knowledge to develop a healthy eating plan, your weight loss is likely to stall. Speaking of which…
Just as big-box stores can be a psychologically tricky terrain for dieters, so to can healthy-sounding labels on the food that we eat. A Cornell University study printed in the Journal of Marketing Research suggests people eat more of a snack that’s marketed as “low fat.” Participants in the study ate a whopping 28 percent more M&Ms that were labeled “low fat” than when the colorful candies didn’t have the label. As we suggested earlier, avoid being fooled by simply opting for full-fat foods.

Every person has a different palate, a unique attitude toward food, and various likes and dislikes. That means you need to find a nutrition plan that works best for you. The phrase "healthy eating" gets thrown around a lot, but for many people, the changes needed to get there aren't as big as they think. It might just be replacing your usual snack for a healthier one, and fixing the one meal each day where you are most likely to overeat.
More than 400 genes have been linked to obesity and weight gain and they can affect appetite, metabolism, cravings and body-fat distribution. The exact degree to which you can be genetically predisposed to weight gain or obesity is unclear, but genes have been associated with difficulty losing weight even as you increase physical activity or low-calorie diets. Much like weight management on the whole, addressing a genetic predisposition for obesity is much easier from a preventative standpoint than a reactionary one.
“Anytime you’re stressed, you probably go for food,” Dr. Seltzer says. (Have we met?!) That’s because cortisol, the stress hormone, stokes your appetite for sugary, fatty foods. No wonder it’s associated with higher body weight, according to a 2007 Obesity study that quantified chronic stress exposure by looking at cortisol concentrations in more than 2,000 adults’ hair.
