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.
Stephen Colbert may be on to something. UCLA Center for Human Nutrition researchers divided study participants into two groups, each of which were fed a nearly identical low-cal diet for 12-weeks. The only difference between the groups was what they were given to eat as an afternoon snack. One group ate 220-calories of pretzels while the other group munched on 240-calories worth of pistachios. Just four weeks into the study, the pistachio group had reduced their BMI by a point, while the pretzel-eating group stayed the same, and their cholesterol and triglyceride levels showed improvements as well. 

"A study by David Jenkins, MD, PhD—the University of Toronto pioneer in low-glycemic eating — demonstrates that eating small portions at frequent intervals is good for your health in a number of remarkable ways. Within the study, they found that people who ate every three hours reduced their blood cholesterol by over 15% and their blood insulin by almost 28%. That's key, because in addition to regulating your blood sugar level, insulin plays a pivotal role in fat metabolism, inflammation and the progression to metabolic syndrome. When your body produces less insulin, you're much less likely to convert dietary calories into body fat.
"Eating directly out of a box or bag (almost always leads to overeating. Serve your food on a plate or in a bowl to keep portion sizes in check and to get used to what one serving looks like. Also, when we take the time to sit down during meals versus standing or driving, we tend to feel more satisfied with our meal. In fact, research shows that you will eat up to 30% more food at the next meal if you ate standing up! Serve yourself, sit down, and enjoy!" — Jennifer McDaniel, MS, RDN, CSSD, LD, food and nutrition expert
At any given time, there are dozens of weight-loss hypes in the marketplace that claim to take off 10 pounds in 10 days, or whatever. Desperation can tempt us to try anything — from "clean eating" to cutting out food groups entirely. Keep in mind: Just because an avocado-kale-salad dripping in coconut oil is deemed "clean" by a so-called "expert" on your Instagram feed does not make it an unlimited food. Moral of the story? Avoid fads, eat real food, watch some Netflix, and unwind (perhaps with a glass of wine in hand). Now that's my kind of detox.

"It's far more difficult to eat a healthier diet and fit in exercise if you don't plan ahead. Plan out your meals for the week ahead and go grocery shopping over the weekend to ensure you have the ingredients you need on hand. If you can, do some meal prep in your downtime—cut fresh veggies, marinate your protein, cook up a batch of whole grains in advance. When you're prepared you're far less likely to order takeout. — Jessica Fishman Levinson, MS, RDN, CDN, culinary-nutrition consultant and founder of Nutritioulicious

"Even though a smart diet is key, exercise can help boost your body's metabolism to shed fat. Through health care providers often recommend brisk walking or jogging, these exercises may not help you see the results you want. Instead, try interval training," shares Dr. Sean M. Wells, DPT, PT, OCS, ATC/L, CSCS Owner and PT, Naples Personal Training, LLC


"A study published in Nutrition Journal found that participants who ate foods high in monounsaturated fats for lunch (in this case, half an avocado) reported a 40 percent decreased desire to eat for hours afterward. Monounsaturated fats from sources like olive oil, nuts and avocados can reduce cholesterol, promote weight loss, even boost memory." — David Zinczenko, author of the Zero Belly Cookbook


"Research continues to support the role of a high-protein diet and weight loss, however, we don't want to reach those protein needs exclusively with animal proteins. Plant proteins found in beans not only help us feel full and stabilize blood sugar but beans are associated with longevity. Who cares about being skinny if you die young?" —Jennifer McDaniel, MS, RDN, CSSD, LD, food and nutrition expert
"The American Heart Association recommends that men eat less than 36 grams of added sugar and that women consume less than 24 grams. However, for optimal weight loss, I tell my male clients to consume less than 20 grams of sugar per day and I tell the women to consume less than 15 grams. The easiest way to cut back on the sweet stuff is by consuming less sugary drinks and dressings. Cut the sugar, lose the fat, regain your health and life." — Dr. Sean M. Wells, DPT, PT, OCS, ATC/L, CSCS
