"No matter how bad off you are when you start, you can still be successful," says Dawn Sabourin, 50. "Don't look at how far you have to go because you will become overwhelmed and quit." And playing the long game can help you feel more in control. "Accept where you are starting and take one step at a time in the right direction. They will build, as will your confidence and success."

You may say you want to lose weight to feel good about yourself. “Why?” Noom asks again. “It’s like peeling back the layers of an onion,” Noom explains, “And yes, tears might be involved too!” By the time our tester answered the third “Why?” she had indeed gone deep — even in the guise of a 40-year-old mom. The ultimate Why she came up with: “To enjoy life and bring joy to others.”
Water isn’t just a calorie-free beverage, it’s also essential to the process of metabolizing fat, known as hydrolysis, says Pence. So it’s important to drink enough fluids every day—and you’ll need even more if you’re overweight. A good rule of thumb is to drink a milliliter of water for every calorie you consume. Not into the metric system? If you’re following a 2000-calorie diet, that comes to 67 ounces or just over a half gallon of water.
Eating less does more for weight loss than exercising more. Consider putting the money you’d spend on a gym membership toward healthy groceries, instead. “Trying to exercise your way out of your weight problem is very difficult (because) it’s very hard to exercise that much,” explained Dr. Aronne. Burning about 3,500 calories equals one pound; someone weighing 150 pounds walking for an hour would burn around 250 calories. “You really need to cut down on calorie intake to lose the weight. Exercise is better at preventing weight gain.” The recommended daily diet is around 2,000 calories, but if you want to lose weight, Dr. Avigdor Arad, the director of the Mount Sinai Physiolab, suggests that women consume between 1,200 to 1,500 calories a day on average, and men between 1,500 and 1,800 calories. But visit your doctor to see how your own metabolism, family history and any medications you’re taking could be influencing how easily you gain and lose weight, and what your nutritional needs are. “There is a lot of variation,” he said.

For this lightning-fast Tabata workout, pick four total-body moves (plank jacks, jump squats, etc.). Do one for 20 seconds, rest for 10 seconds, then do it again. Continue to the next move and repeat. The routine is just four minutes long—and you’ll torch 13½ calories a minute and double your calorie burn for half an hour afterward, per research from Auburn University in Alabama.


Consider a weight loss program’s overall approach to food. What will you be eating every day? Does the meal plan react poorly with your food allergies or intolerances? Does the program cater to your special dietary needs, for example, if you are vegan or diabetic? If most (or even some) of the foods are not enjoyable to you, within your budget or readily available, you're going to find that plan tough to stick with.
Lifestyle fit: Figure out whether a plan is compatible with your lifestyle before committing. Some meal plans are very simple; others require more work. Think about how much time and planning goes into each weight loss program. Some people find that meal planning and preparation takes up too much time, while others enjoy planning meals and spending time in the kitchen. 
To start off, aim to do ab work 3 or 4 times a week on non-consecutive days with at least 24 hours of rest in between sessions, says Gagliardi. During those sessions, you can start with simpler moves like crunches, bicycle crunches, and planks. Even though you may only be directly targeting your abs 3 or 4 times a week, you should still be activating your core (aka, tightening your ab muscles) in every workout you do, says Gagliardi.

Similar to the CICO diet, the Body Reset has gained popularity via social media, and there isn’t any definitive research that suggests the approach is safe and effective. Celebrity trainer Harley Pasternak created the plan, which is essentially a three-phase liquid diet comprised of smoothies and moderate exercise. While U.S. News notes you may lose weight on the diet, it may be tough to stick with, and isn’t safe for people with diabetes and heart disease. (38)
Whereas many beverages can increase your waistline (see above), there is one that is guaranteed to trim your tummy: water. Drinking plain ol’ H2O works because staying fully hydrated tells your body it’s okay to release any extra water it’s retaining, decreasing the accompanying bloat. Plus, drinking water has been proven to reduce cravings for sweets, lower your appetite, and help you feel satiated faster. Here 9 more ways to bust belly fat in a single day!
