Ketosis is the metabolic basis for all “keto” or “ketogenic” diets. On a normal diet that includes carbohydrates (sugar and starchy foods), the body transforms these carbs into glucose, which is used as the body’s main source of energy. But, when we consume a minimum amount of carbs, the body will look elsewhere for that much-needed energy, and that “elsewhere” is fat. In short, when the body goes into ketosis, it is burning fat instead of carbs.
"In order to increase your resting metabolic rate, it is the consistency of exercise that is crucial and not the intensity or duration. Focus on consistent, quality movement (walk, bike, climb, paddle board, etc.) every day, rather than embracing the weekend warrior mentality." — Timothy Lyman, ACE certified personal trainer and Director of Training Programs at Fleet Feet Pittsburgh
"When you're anxious, your body feels like it's under a tremendous amount of stress all the time. This is why anxiety is a powerful trigger for weight gain. Two of the most proven cures for anxiety are exercise and spending time in nature. Combine both with an outdoor run or bike ride and race away from the anxiousness. Making this habit part of your lifestyle can help you stay lean for life." — David Zinczenko, author of the Zero Belly Cookbook
Popularized by the documentary Forks Over Knives, the Ornish diet is a low-fat, plant-based diet plan based on whole grains, vegetables, fruits, and legumes. It's based on a lacto-ovo style of vegetarianism, allowing only egg whites and nonfat dairy products. It's packed with vitamins, fiber, and lots of filling plants to keep you satiated. Some studies have shown it can reverse heart disease and have beneficial effects on other chronic health conditions. (BTW, there is a difference between a vegan diet and a plant-based diet.)
This popular diet program is fairly restrictive — and for the first 30 days, dieters must cut out grains, legumes, most dairy, added sugar, and alcohol without any slip-ups, according to the Whole30 website. (29) The aim is to “reset” your body and to adopt dietary habits resulting in weight loss. Cutting out added sugar and alcohol has merit, but all the restrictions prove challenging and could lead to nutrient deficiencies and disordered eating.
The most unique aspect of Noom is that it lets you communicate with your personal coach via text message as many times as you want, so you can work hand in hand towards your goal without missing a step. Sometimes, a simple word of advice or support can make all the difference, especially during the stressful moments that inevitably happen during a strict diet. Also, in case you forget to log in your foods, the app will send you reminders via pop up messages.
"Whether it's an app or paper food logs, tracking what you eat will certainly be eye-opening. Almost everyone consumes more than they think. Write everything down as soon as you're done eating so you don't forget anything. The simple act of recording what you eat will make you eat less. When the calories are in your face, it makes you think twice!" — Martha McKittrick, RD, CDE
"Use a VersaClimber or take a VersaClimber class. These machines are still not that common, but in my opinion they are far more effective for weight loss than other forms of cardio. They require you to use a large portion of your muscles and it's functionally better for you than other forms of cardio like spinning. Everyone is talking about Rise Nation in LA at the moment as they are the first dedicated VersaClimbing studio. There's no harder cardio workout I have tried. To lose fat you have to put in the work. — Dan Roberts, celebrity trainer and creator of Methodology X
A big part of weight loss is simply being aware of the decisions you’re making. For example, when out at happy hour with friends, you may lose track of how much you're eating or drinking. But if you take a split second to step back and become aware of that fact, you’re more able to course correct. “The awareness and then planning for what else I can be doing, that might give me the same benefit of eating comfort foods,” says Gagliardi.
The Dietary Approach to Stop Hypertension, like the TLC described earlier, is endorsed by the National Heart, Lung, and Blood Association, the American Heart Association, and the 2015 Dietary Guide for Americans. It was developed with the purpose of helping people reduce blood pressure, prioritize the consumption of calcium, potassium, and magnesium, and, most importantly, abstain from sodium.
When it comes to the "best" diet for most people, this one consistently ranks at the top of every list. If you can't afford a cruise to the Mediterranean (yet!), at least you can eat like the beautiful, long-living, and famously healthy people from the region. The Mediterranean diet teaches you to eat like a Sardinian, one of the "blue zones" identified by researchers as having a high number of people living past 100—by eating more fish, olive oil, healthy fats, and fresh vegetables. The point is to have not just a longer life but also a healthier and happier one, whether you're trying to lose weight or not. (Really—research shows that you can reap the benefits of the Mediterranean diet without cutting calories.)
Spending more time in the kitchen can help you shed belly fat, as long as you’re cooking with the right foods, according to one 2017 study. After analyzing data from more than 11,000 men and women, UK researchers found that people who ate more than five homemade meals per week were 28 percent less likely to have a high body mass index, and 24 percent less likely to carry too much body fat than those whole only downed three meals at home.
In what is perhaps the biggest buzzkill of all time, sex doesn’t quite count as cardio or burn a significant amount of calories: Women burn about 3.6 per minute. "It’s still a good idea," Dr. Seltzer says, citing the activity’s other benefits, like increasing the output of the neurotransmitters serotonin and dopamine, which naturally reduce food cravings.
