If you don’t have an established exercise routine, “walking is a pretty good entry point for people,” says Gagliardi. One small study published in The Journal of Exercise Nutrition & Biochemistry found that obese women who did a walking program for 50-70 minutes three days per week for 12 weeks significantly slashed their visceral fat compared to a sedentary control group.
Research also finds that drinking frequently—even if it’s a moderate amount—can set you up for excess pudge. Not only do the beverages themselves contain unnecessary calories, but once you start sipping too much, your inhibition also plummets, according to one 2016 study. The result? You’ll have a hard time resisting that late-night slice of pizza. So if you're going to imbibe, be sure to stick to one drink per day for women and up to two drinks for men.

Ultimately, long-term weight loss requires some short-term behavior change and healthier habit formation. That's why we created our Good Housekeeping Nutritionist Approved Emblem, which exists to help turn smart food choices into healthier eating habits. All GHNA foods and drinks make it easier to find — and eat — good-for-you foods without additional time, effort, and cost. We target the lifestyle-related factors that make healthier eating hard, and find simple but creative solutions that actually work! Look for the emblem on labels wherever you shop for food.
Based on the concept of caloric density, which states that some foods have few calories in proportion to their size (say, a lettuce), while others have lots of calories packed in small portions (a regular chocolate chip cookie comes to mind), Volumetrics divides foods into 4 categories based on their calorie/volume ratio, and is perfect for people looking to binge on some foods while still shedding pounds. However, as with the calorie counting approach, Volumetrics does not take into account the quality of the calories, prioritizing quantity instead. The app Noom and Weight Watchers (both reviewed above) share similarities with this diet theory.
