Going way beyond your BMI–-a measure of your height and body weight--the scale calculates your percentage body fat, including your visceral fat area (VFA), which provides the most accurate measure of your risk for adverse cardiac events such as heart attack and stroke. BMI is not a true reflection risk of your cardiac risk since increased skeletal muscle mass in relation to height can elevate your BMI, falsely elevating cardiometabolic risk.
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 [12], or influence estradiol concentrations through pathways such as hepatic aromatase induction, with an initial inhibition and a later stimulation [50]. 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 [51]. 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 [52]. 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 [52].
Think writing a grocery list before heading to the store is a waste of time? As it turns out, it may be the key to finally losing weight. A Journal of Nutrition Education and Behavior study of more than more than 1,300 people discovered that shoppers who regularly wrote grocery lists also purchased healthier foods and had lower BMI’s than those who didn’t put pen to paper before heading to the store. Researchers hypothesize that shopping lists keep us organized, which in turn helps us fend off diet-derailing impulse buys (hello, candy aisle). Before heading to the supermarket to stock up, spend a few minutes taking inventory of your kitchen, and then write a list. Be sure to organize it by category to prevent zigzagging all over the place; that ups the odds you’ll walk by—and purchase—tempting treats that could derail your weight loss success.
Assume a prone position on the floor with the knees fully extended and the toes pointed down to the floor. Place hands on floor, palms down, about 2 to 3 inches wider than shoulder-width apart, with elbows pointed outward. Keeping your body in straight line and toes in contact with the floor, push against the floor with the hands to fully extend the elbows. Pause at the top and then lower to starting position.
“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.
