Making meals from scratch is time-consuming, sure, but relying on frozen dinners and other packaged products won't help you out in the long run. One recent study found that we burn 50% more calories metabolizing whole foods than processed foods. So not only are you likely to decrease your calorie intake when prepping your own meals, your body will thank you with a metabolism boost.
Did bikini season sneak up on you? Is your soon-to-be worn wedding dress still just a touch too tight? Did a last-minute invite for a beach getaway come your way? You're a lucky dog – and a panicked one too because you want to drop pounds, and fast. These 10 diets are likely to help you lose significant weight within a year, according to a panel of experts who reviewed 38 plans for the U.S. News Best Diets rankings. Just remember: Short-term weight loss is markedly different from long-term weight loss, which is more important for your health.
Because the diet isn’t as restrictive as a traditional vegan or vegetarian diet, it may be simpler to stick with — hence its No. 2 ranking in U.S. News & World Report’s Easiest Diets to Follow category. Because you’ll be eating meat some of the time, you may also be at a lower risk of the aforementioned nutrient deficiencies that vegetarians and vegans may face.
In a new study, Stanford University researchers put more than 600 overweight adults on either a healthy low-fat or low-carb diet. It turns out, participants had similar levels of weight loss success on each plan. Researchers looked for clues (such as insulin levels and gene patterns) to see if there are any factors that might make someone more successful on either diet, but after combing through the data, they were not able to make any connections. Since it may take years before scientists discover individual traits that could lead to more success on one plan compared to another, for now, we can learn a lot — and lose a lot! — by recognizing the dieting advice that all experts agree on.
“The alkaline diet often has a focus on eating lots of fresh produce and unprocessed foods, which could be a good thing,” says Hultin. “However, keep in mind that this is not an evidence-based therapeutic diet. When people take it too far — for instance, drinking baking soda — or become too restrictive or obsessive over food choices, it can definitely turn negative.”
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.
One note about this diet plan before we dive in. A personal trainer by professional, Jillian Michaels’ weight loss plans are not for the faint of heart. She’ll take you on a journey, transform your body, and make you reach the fitness goals you’ve been craving…but it won’t come easy. Go into this plan with the determination and awareness that you’ll be working hard, and the results will really amaze you.
You can blame biology for your sweet tooth. We’re hardwired to have a preference for sweets, and this drive is universal and begins early on, according to research on the subject. Sugar makes food taste good, so food companies add it to everything from breads to soups to salad dressings to cereals, yogurts and more. This adds up to way too much sugar!
A. Possibly. "You need more calories when you're active and fewer when you're sedentary," explains Jackie Newgent, R.D., a New York City based nutrition consultant. So if you're eating the bulk of your calories while you're sitting in front of the TV, you may indeed store more of them as fat. "However, what matters most when it comes to losing weight is how many total calories you take in and burn off throughout the day, not just within a limited time frame," Newgent says. If swearing off snacks after 8:00 helps you reduce your overall calorie intake, go for it, but don't forget to keep track of the whole day's tally as well.
Red wine can actually be good for your health, thanks to the antioxidant resveratrol, which studies have shown is good for your health and could help you lose weight. But any more than one glass, and you’re opening yourself up to extra sugar, empty calories, and a boozy buzz, which may inhibit your ability to make healthy food choices. If you’re out to happy hour, stop at one glass and opt for club soda (which is calorie free) or water with lemon instead.
Build muscle. Muscle burns more calories than fat. So adding strength training to your exercise routine can help you reach your weight loss goals as well as give you a toned bod. And weights are not the only way to go: Try resistance bands, pilates, or push-ups to get strong. A good, well-balanced fitness routine includes aerobic workouts, strength training, and flexibility exercises.
So how does this work? A quick run-through: The first tip was to eat low carb. This is because a low-carb diet lowers your levels of the fat-storing hormone insulin, allowing your fat deposits to shrink and release their stored energy. This tends to cause you to want to consume fewer calories than you expend – without hunger – and lose weight. Several of the tips mentioned above are about fine-tuning your diet to better this effect.
High blood sugar levels coupled with high blood ketones, on the other hand, will mean that you have a pathologically low level of insulin – something non-diabetics do not suffer from. This can lead to ketoacidosis – a potentially life-threatening condition. If this happens, you’ll need to inject more insulin; if you’re at all unsure of what to do, contact a medical professional. Coveting really high blood ketones for weight control is not worth the risk for type 1 diabetics.

Nuts were also among the top 5 foods that promote weight loss according to Harvard. That's probably because peanut butter and all nuts and nut butters deliver a good dose of healthy fats, fiber and protein—all satisfying nutrients. Nuts used to get a "bad" reputation for being high in calories and fat. And while nuts and nut butters are calorie dense—2 tablespoons of peanut butter has just under 200 calories, 7 grams of protein and 2 grams of fiber—they're also nutrient dense and help you build a satisfying breakfast.
The best diet for losing weight is Weight Watchers, according to the experts who rated the diets below for U.S. News. Volumetrics came in second, and Jenny Craig and the vegan diet were third on this overall weight loss ranking list, which takes into account short-term and long-term weight loss scores. Some other diets performed as well or better in our rankings for enabling fast weight loss, but long-term weight loss is more important for your health.
