REALITY: Bro-scientists will insist that eating small portions every 2-3 hours will increase your metabolism. They base this on the thermic effect of food (TEF), which refers to the energy (calorie) cost of your body processing the food you consume. On average, 15 percent of the calories you consume are burned by processing them (although the rate varies by macronutrient). Someone took this idea and assumed that the more frequently people consume their meals, the more frequent TEF will take effect and thus increase fat oxidation.
It depends on just how many potatoes we're talking here! One medium potato has around 37 grams of carbs, so if you limit your carb count elsewhere, this is no problem. What you really have to watch out for are the toppings, like butter, cheese, sour cream, bacon, and rich sauces like gravy. Do some math to figure out how to balance the carbs from your potato and toppings with the other foods you eat.
“Speed is key—move, walk, or run a little faster and you’ll burn more total calories,” says Kravitz. In fact, changing up your walking pace quickly and frequently can help you melt up to 20% more calories, compared with maintaining a constant speed, according to a 2015 study from The Ohio State University. Try speeding up for 30 seconds, then walking at a comfy pace for three minutes.
You may have heard the widely quoted statistic that 95% of people who lose wait on a diet will regain it within a few years—or even months. While there isn’t much hard evidence to support that claim, it is true that many weight-loss plans fail in the long term. Often that’s simply because diets that are too restrictive are very hard to maintain over time. However, that doesn’t mean your weight loss attempts are doomed to failure. Far from it.
That sour cherry is pretty sweet when it comes to your health. The results of a study conducted at the University of Michigan found that rats given high-fat foods along with tart cherries ditched nine percent more body fat than those in a control group over just 12 weeks. Cherries are also a good source of antioxidant pigment resveratrol, which has been linked to reductions in belly fat, dementia risk, and lower rates of macular degeneration among the elderly.
Jame LeCheminant and colleagues looked at the short-term effect restriction of night eating had on daily calorie consumption, weight trends, and even mood associated with this deprivation. They recruited 29 young men and asked them to avoid consuming calories (water was okay) between the hours of 7 p.m. to 6 a.m. for two weeks. During these two weeks the participants recorded every bite they consumed, and their weight, mood, and level of hunger at breakfast were monitored. There was a one-week break, and then for two more weeks (a control period) the subjects were monitored as they returned to their usual way of life. That’s it. There were no other interventions or exercises to perform.
Do this: One way to slow digestion is to eat carbs with protein and small amounts of fat. Never eat carbs alone. Accompany that bowl of cereal, for example, with scrambled egg whites or cottage cheese. Alternatively, you could eat plenty of vegetables, such as broccoli, cauliflower, green beans, and green salads, with your meals. These foods actually slow the breakdown and digestion rate of all carbohydrates.
When Johns Hopkins researchers compared the effects on the heart of losing weight through a low-carbohydrate diet versus a low-fat diet for six months—each containing the same amount of calories—those on a low-carb diet lost an average of 10 pounds more than those on a low-fat diet—28.9 pounds versus 18.7 pounds. An extra benefit of the low-carb diet is that it produced a higher quality of weight loss, Stewart says. With weight loss, fat is reduced, but there is also often a loss of lean tissue (muscle), which is not desirable. On both diets, there was a loss of about 2 to 3 pounds of good lean tissue along with the fat, which means that the fat loss percentage was much higher on the low-carb diet.
At its core, burning fat comes down to the process of lipolysis—the breaking down of fat lipids, explains Seedman. This happens in the mitochondria of the muscles, or the powerhouses of the cells, responsible for generating the energy our cells need to do their jobs. Exercise has been shown to improve mitochondria function, which then promotes fat breakdown, Seedman adds. Plus, working out helps regulate pretty much all the hormones that optimize fat loss.
