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).
Bad diet decisions are often made when you’re starving and have nothing healthy to eat in your kitchen. Ward off diet-derailing decisions by stocking up on frozen, deveined shrimp—one of Insanity trainer Shaun T’s! go-to proteins. Once you throw it on the stove, it’s ready to eat in just a few minutes, and it’s a great source of lean, low-cal protein. Organic, low-sodium turkey breasts, pre-grilled chicken and hard-boiled eggs are also smart meal-starters to keep on hand.
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.

Fermented foods: These enhance the function of good bacteria while inhibiting the growth of bad bacteria. Sauerkraut, kimchi, kefir, yogurt, tempeh, and miso all contain good amounts of probiotics, which help to increase good bacteria. Researchers have studied kimchi widely, and study results suggest that it has anti-obesity effects. Similarly, studies have shown that kefir may help to promote weight loss in overweight women.


Though you may think skipping a meal such as breakfast will help you lose weight because you would be consuming fewer calories, numerous studies have actually shown that bailing on breakfast is bad for your waistline. Why, you ask? It turns out that skipping breakfast not only means you’ll likely consume more calories later in the day, but eating more calories in the later part of the day is a nightmare for metabolic circadian rhythms, which help keep your weight in check.
Coffee jumpstarts your metabolism, making the non-decaf stuff a worthy weight loss ally. According to a study published in the journal Physiology & Behavior, the average metabolic rate of people who drank caffeinated coffee was 16 percent higher than that of those who drank decaf. And remember, don’t ruin your fat-blasting cup of joe by adding any unhealthy creamers and/or artificial sweeteners to it, both of which are enemies of weight loss.

A retreat joins like-minded people open to share their journeys and learning about yours. Practicing exercises, learning and experiencing new things together for several days or even weeks creates a foundation for friendship hard to topple in a busy everyday life environment. You might even end up supporting each other and sharing progress back home.


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.
A healthy weight loss program should never be about dieting alone. It should be a balanced approach including nutrition that’s right for your metabolism, sensible exercise, food preparation management and the right mindset.  This retreat embodies that holistic approach, with personalized tools to get your weight to where you want it to be and continued support with weight management thereafter. Your pre-arrival consultation will guide our team of nutritionists, chefs, personal trainers, physiologists and instructors, to prepare your bespoke plan of action and help you execute it.
“The weight starting coming off,” she says. “I remember I lost 9 lbs. my first week. After I had lost 100 lbs., I started trying more adventurous exercise. I became fascinated by fitness and seeing what new things I could accomplish with my body. I do things that I never dreamed were possible like running races, lifting heavy weights, and completing a sprint triathlon.”

Did you know that running for a straight hour on the treadmill is about three times LESS effective than just 15 minutes of interval training? If that isn't enough, the American College of Sports Medicine Annual Meeting says that doing just two weeks of high-intensity interval training will improve your aerobic fitness as much as about seven weeks of endurance training.

That’s one way the beautifully presented, animal-protein-centric food comes in. Of course, protein is excellent fuel, but the meal plan is also meant to prove that healthy choices don’t require deprivation. You can eat more or less like a normal American, red meat and all (though they accommodate vegetarians handily). Between the reasonably sized meals and copious snacks (to keep blood sugar even), I was never hungry, and occasionally doubted that it really added up to 1,200 calories a day (1,400 for men)—though the fat-measuring scale convinced many of us otherwise.
In the 2-year POUNDS Lost randomized clinical trial based in Boston, Massachusetts, and Baton Rouge, Louisiana, that examined the effects of energy-restricted diets on weight changes, baseline plasma concentrations of major PFASs were measured among 621 overweight and obese participants aged 30–70 years. Body weight was measured at baseline and 6, 12, 18, and 24 months. RMR and other metabolic parameters, including glucose, lipids, thyroid hormones, and leptin, were measured at baseline and 6 and 24 months. Participants lost an average of 6.4 kg of body weight during the first 6 months (weight-loss period) and subsequently regained an average of 2.7 kg of body weight during the period of 6–24 months (weight regain period). After multivariate adjustment, baseline PFAS concentrations were not significantly associated with concurrent body weight or weight loss during the first 6 months. In contrast, higher baseline levels of PFASs were significantly associated with a greater weight regain, primarily in women. In women, comparing the highest to the lowest tertiles of PFAS concentrations, the multivariate-adjusted mean weight regain (SE) was 4.0 (0.8) versus 2.1 (0.9) kg for perfluorooctanesulfonic acid (PFOS) (Ptrend = 0.01); 4.3 (0.9) versus 2.2 (0.8) kg for perfluorooctanoic acid (PFOA) (Ptrend = 0.007); 4.7 (0.9) versus 2.5 (0.9) kg for perfluorononanoic acid (PFNA) (Ptrend = 0.006); 4.9 (0.9) versus 2.7 (0.8) kg for perfluorohexanesulfonic acid (PFHxS) (Ptrend = 0.009); and 4.2 (0.8) versus 2.5 (0.9) kg for perfluorodecanoic acid (PFDA) (Ptrend = 0.03). When further adjusted for changes in body weight or thyroid hormones during the first 6 months, results remained similar. Moreover, higher baseline plasma PFAS concentrations, especially for PFOS and PFNA, were significantly associated with greater decline in RMR during the weight-loss period and less increase in RMR during the weight regain period in both men and women. Limitations of the study include the possibility of unmeasured or residual confounding by socioeconomic and psychosocial factors, as well as possible relapse to the usual diet prior to randomization, which could have been rich in foods contaminated by PFASs through food packaging and also dense in energy.
Weight loss can be intentional, such as from dieting and exercise, or unintentional and be a manifestation of illness. Weight loss can result from a decrease in body fluid, muscle mass, or fat. A decrease in body fluid can come from medications, fluid loss, lack of fluid intake, or illnesses such as diabetes. A decrease in body fat can be intentionally caused by exercise and dieting, such as for overweight or obesity. Weight loss is normal after pregnancy. Other causes of weight loss include, but are not limited to, cancer, viral infection (such as CMV or HIV), gastroenteritis, parasite infection, depression, bowel diseases, and overactive thyroid (hyperthyroidism).
