Big-box stores such as Costco or Sam’s Club are great money-savers, but frequenting them to buy groceries can be bad news for your fitness goals. That’s because a 2015 study in the journal Appetite found that the larger the bottle, bag, or box the food comes in, the larger we think the serving size should be. To come to that conclusion, researchers surveyed more than thirteen thousand people and found that when confronted with larger packages of cola, chips, chocolate, or lasagna, the shoppers tended to want to serve themselves larger portions.

To date, evidence on the influence of PFAS exposure on body weight change and metabolic parameters has been limited and has been primarily generated from cross-sectional studies that could not establish causal relationships [30,44–47]. In addition, the causes of weight change are likely heterogeneous (including diet, physical activity, and medications) and often not well understood in observational studies. Prospective evidence linking PFAS exposure with body weight regulation was primarily from studies that examined prenatal or early life exposures to PFASs in relation to body weight later in life, and the results were somewhat mixed [21–27,48,49]. For example, in 3 birth cohort studies conducted in European populations, maternal concentrations of PFASs were significantly associated with offspring body weight and other anthropometric and metabolic traits, primarily among girls [21,23,25]. However, other studies generated inconsistent findings regarding maternal PFAS exposure and offspring BMI or obesity risk, with no sex difference [22,24,49]. In addition, recently, in the European Youth Heart Study, Domazet et al. demonstrated that higher plasma PFOS concentrations during childhood, but not adolescence, were associated with greater adiposity in adolescence and young adulthood [48].
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.
HIIT (High Intensity Interval Training) is a type of workout becoming more and more widespread through gym classes and exercise videos such as P90X and Insanity. This way of exercising yields great results because they combine high intensity movements with very little rest in between. As a result, you can fit in a fantastic fat-burning workout in a short amount of time.
Aim to get at least seven hours of sleep each night. Try going to bed and waking up at the same time each day. Get these seven tips for the best sleep ever! Why? Ever notice how you start to crave donuts and drive-thru breakfasts when you’re exhausted? When you don’t get enough sleep, your hormones are thrown out of balance. Running on no sleep can actually drive up the hormones that make you want to eat, while pushing down the hormones that signal for fullness—and that’s a recipe for weight gain. When you’re well-rested, it’s much easier to make healthy decisions and stay on track.
