In our pilot study evaluating the within-person stability of PFAS concentrations, intra-class correlation coefficients (ICCs) between concentrations in 2 blood samples collected 1–2 years apart from 58 participants in the Nurses’ Health Study II demonstrated excellent reproducibility of PFAS concentrations in blood: the ICCs were 0.91 for PFOS, 0.90 for PFOA, 0.94 for PFHxS, 0.87 for PFNA, and 0.82 for PFDA (all P < 0.001).
Evening eating is often the most problematic for women, as it can be related more to emotional issues than to real hunger. You're tired, lonely, bored, anxious; you want to relax or reward yourself after a tough day. But indulge too many nights in a row and that temporary water gain becomes permanent fat gain — and fatter abs, rather than the flat abs you want.
We’ve been clear on the benefits of wild salmon, but those pink creatures are quite literally not the only fish in the sea. Generally speaking, fish provide one of the best sources of fatty acids known as omega-3s, which will help fend off waist-widening inflammation and are an excellent source of high-quality, lean protein. This allows them to help you maintain muscle mass, thus reducing excess fat accumulation. Some of our favorite healthy seafood include mussels, Atlantic mackerel, and bluefish, but be sure to educate yourself on the ocean dwellers with this list of Every Popular Fish—Ranked for Nutritional Benefits!

“This is for me but this is also for my family. Because what’s the point of…not truly enjoying yourself. Not being present with your kids and your husband but being somewhere in the past or being scared of something in the future and not having the knowledge of being in my body and feeling comfortable in it and feeling present” – Marisol Peeples, Texas
Sure, trampolines are built for kids, but as an adult, using one for rebounding is a great way to flatten your tummy and get rid of excess fat. “Not only is it a great cardio workout (which is the first step to tightening up your midsection) but it makes your core work like crazy so you are getting the cardio plus the toning: everything you need for a tight tummy!” explains Hope Pedraza, a Certified Personal Trainer through American College of Sports Medicine in 50 Ways to Shrink Your Belly. To get a comprehensive workout using a mini trampoline, Pedraza suggests jumping, lifting your knees up high, twisting, adding some light weights to move around while you’re jumping, and moving in all directions in different planes.
Don't get me wrong — exercising at any time is good for you. But evening activity may be particularly beneficial because many people's metabolism slows down toward the end of the day. Thirty minutes of aerobic activity before dinner increases your metabolic rate and may keep it elevated for another two or three hours, even after you've stopped moving. What that means for you: You're less likely to go back for seconds or thirds. Plus, it'll help you relax post meal so you won't be tempted by stress-induced grazing that can rack up calories, quickly.
When it’s doing its job properly, inflammation in the body helps fight off infection. But in people who are overweight or obese, inflammation can get out of control, which increases insulin resistance as well as your risk for heart disease, cancer, arthritis, and even Alzheimer’s disease. “Excess body fat, especially when it’s located around the abdomen, is strongly linked to inflammation,” Dr. Webster says. Adipose fat tissue releases inflammation-causing molecules, but the markers of inflammation go down with even a 5 or 10 percent reduction in body weight, she says. Eat more of these 15 superfoods that can help you lose weight.
Now extreme weight manipulation can go horribly, horribly wrong. Even a lot of UFC guys don’t know how to do it the smart way. Instead, they put their bodies in real harm by doing stupid things like taking a lot of diuretics, not drinking any water, skipping meals, wearing trash bags while exercising (sometimes in the sauna) and generally being idiotic.
Fighting constantly with your S.O.? It’s time to address your issues head-on. "Research has shown that cortisol, the hormone that's released during stressful activity, is linked to fat storage,” says Gina Guddet, couples counselor and co-author of Love Metabolism. “And poor communication between couples is the most common type of stress that you tend to experience."
At baseline, 6 months, and 24 months, fasting plasma glucose, insulin, total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides were measured on the Synchron CX7 (Beckman Coulter), and hemoglobin A1C (HbA1c) was measured on a Synchron CX5 (Beckman Coulter); plasma leptin and soluble leptin receptor were measured by an ultrasensitive immunoassay (R&D Systems); and serum free triiodothyronine (T3), free thyroxine (T4), total T3, total T4, and thyroid stimulating hormone were measured using a competitive electrochemiluminescence immunoassay on the Roche E modular system (Roche Diagnostics), as previously described elsewhere . The homeostatic model assessment of insulin resistance (HOMA-IR) value was calculated using the updated HOMA model (HOMA2) described by Levy et al. . Adipose tissue was obtained from 103 participants at baseline and at 6 months. Gene expression was measured by direct hybridization using the Illumina HumanHT-12 v3 Expression BeadChip (Illumina) (details in S1 Text).
The Lenox Health Resort Weight Loss Program at Canyon Ranch eschews what it calls “tedious, cookie-cutter weight-loss directives and dreary menus” and instead offers guests a whole-person program with access to top experts in nutrition, exercise physiology, life management, and lifestyle medicine – all working to tailor the best weight loss plan for each guest. Stays range from 1 week and longer, with an all-inclusive no-tipping plan with meals and lodging.
Some scientists subscribe to the idea that your body has a set weight point and all of the above – your metabolism, hormones, brain – will adjust to maintain that weight. The theory goes that people can have naturally higher or lower set weights than others and genetics, aging, history of weight loss and other hormonal shifts can all impact your set weight. Moreover, set points can rise but very rarely do they lower. Similarly, they are much easier to maintain – because your body wants to – than reduce, which is why maintaining a healthy weight is easier than losing weight.
Weight loss, in the context of medicine, health, or physical fitness, refers to a reduction of the total body mass, due to a mean loss of fluid, body fat or adipose tissue or lean mass, namely bone mineral deposits, muscle, tendon, and other connective tissue. Weight loss can either occur unintentionally due to malnourishment or an underlying disease or arise from a conscious effort to improve an actual or perceived overweight or obese state. "Unexplained" weight loss that is not caused by reduction in calorific intake or exercise is called cachexia and may be a symptom of a serious medical condition. Intentional weight loss is commonly referred to as slimming.
Places like airports, drug stores, and even home-goods stores all sell food, but it's usually not very healthy. Instead of shopping until you feel famished then buying whatever unhealthy items are available near the checkout stand, plan ahead and pack a nutritious snack. Sliced apples and peanut butter, carrots and hummus, or Greek yogurt and nuts are all inexpensive and convenient options.
Are frequent meals your ticket to a better body? Experts say so! In a Journal of the Academy of Nutrition and Dietetics study that sampled 2,385 adults, research participants who ate less than four times a day consumed more calories and had a higher BMI than those who sat down to eat at least six times. The scientists noticed that those who ate fewer meals consumed most of their calories at night and were more apt to drink alcohol with their meals while their ever-grazing counterparts tended to eat healthier, less calorically dense foods. To keep the weight flying off your frame, nosh on these high-protein snacks between meals.
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.
