We pulled the top 14 of the best commercial diets (marketed to the public for profit) and the top 12 of the best diets overall. We also threw five of the most popular diet apps into the mix. Since these are largely tracking devices that don’t espouse unique eating habits, they don’t appear to meet US News’ definition of diet, but are still potentially effective weight loss tools.
This study affirms, as many have before, that we can in fact cut calories and, at the same time, eat till we’re full and satisfied when we reduce the calorie density of the foods we eat. The research found that all three strategies to reduce calorie density led to a spontaneous reduction in ad libitum calorie intake, but the reductions in calorie intake were significantly greater with fat reduction.
While the American College of Sports Medicine warns that women who eat less than 1,300 calories a day and men who eat less than 1,800 risk slowing down their metabolism over time. But a rev-up stage that only lasts two weeks is approved by doctors and isn’t as difficult as it seems. Our tester found the Mayo Clinic day pretty satisfying, and still had enough energy to hit the gym.
What's more trustworthy than a diet built by experts from the Mayo Clinic? Created by doctors, nutritionists, and all-star chefs, the plan has a few phases: In the first, you should lose 6 to 10 pounds in two weeks. After that, you can expect to lose 1 to 2 pounds a week until you reach your goal weight. You're also given plenty of resources and advice to help you keep the weight off.
"When going out for fast food, I used to get the large-size value meal. Now, I satisfy a craving by ordering just one item: a small order of fries or a six-piece box of chicken nuggets. So far, I've shaved off 16 pounds in seven weeks, and I'm on track to being thinner than my high school self for my 10-year reunion later this year." —Miranda Jarrell, Birmingham, AL
If you want to make a simple switch that can make all the difference in weight-loss success, trade out refined grains (white bread) for whole grains (100% whole-wheat bread) on your sandwich. Choosing whole over refined grains can help turn up your resting metabolism and prompt your body to absorb fewer calories, helping you burn nearly 100 extra calories per day, suggests a new study in The American Journal of Clinical Nutrition. It may be the fiber in whole grains that affects digestion and metabolism, researchers point out. Other great sources of whole grain include oatmeal, brown rice, barley, farro and even popcorn. Try grain bowls for an easy, packable work lunch.
One of the easiest ways to burn some extra calories is to get up from your chair at work; standing burns 50 more calories per hour than sitting, according to a British study. If you are lucky enough to have a standing desk, make sure you utilize it. If not, you can easily make your own by stacking books or boxes on your desk and standing up to work. At the very least, make sure you’re taking a break every hour to stand up and stretch, and possibly go for a walk around the office. Every bit of movement counts!
Another danger of losing weight too quickly, as Dr. Hensrud points out, is that you are probably not losing just fat. A normal, healthy rate of weight loss is one to two pounds per week. Because it's difficult for your body to burn large numbers of fat calories in a short amount of time, the weight you lose could be made up of water or muscle (lean tissue).
Caffeine itself may play a synergistic role in increasing metabolic rate. A meta-analysis of 15 studies showed that shows that green tea catechins given with caffeine was able to decrease body weight compared to catechins given alone. I will note that green tea does in fact contain some caffeine, whereas green tea extracts are may or may not contain it. Some studies sugges that regular and high caffeine usage may blunt the benefits of the GTE. In one study, using more than 300 mg/day of caffeine daily negated much of the benefits (a cup of brewed green tea only has 30 mg caffeine). Caucasian population typically drink more coffee and perhaps higher doses of catechins are necessary for benefits.
