This double-blind clinical trial study was conducted on 42 obese and overweight individuals (25 < BMI < 35). Participants were selected from those, who referred to a nutrition clinic (Ahvaz, Iran). Participants were screened based on the inclusion and exclusion criteria. Inclusion criteria were lack of physical activity, no smoking, no alcohol drinking, no usage of herbal supplements and vitamins, and lack of weight changes in the last 6 months. Exclusion criteria included pregnancy, breastfeeding, use of drugs that effect metabolism, lipid and glycemic profile, eating disorder, diabetes, cardiovascular disease, kidney problems, thyroid, digestive, respiratory diseases, and cancer. Participants consuming more than 300 mg of caffeine daily (described as caffeine users) were excluded from the study (20). The level of physical activity was assessed weekly by phone. The subjects, who had moderate or various physical activities, were excluded from the study.
Consistent with the current study, recent findings indicate that slow weight loss, as recommended by current guidelines, worldwide, is not a priority over rapid weight loss. Purcell et al. in a clinical trial studied the effect of weight loss rate and weight management. Their results showed that in the long-term, with rapid weight loss (450 to 800 Kcal/day) than gradual weight loss (500 kcal less than the daily requirement), the weight loss is faster and more stable. The researchers suggested that the limited carbohydrate intake of very-low-calorie diets might promote greater satiety and less food intake by inducing ketosis. Losing weight quickly may also motivate participants to persist with their diet and achieve better results (29).
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.
That said, carrying extra weight around the middle is also tied to increased heart risks, making it arguably unhealthier to be an overweight man than a plus-size woman. Big bellies, it turns out, are a sort of a double-edged sword when it comes to weight loss: They're an extra health risk for men, but give guys the edge when it comes to dropping pounds. 

A is for attitude. A can-do attitude will help you get over the inevitable hurdles of weight loss. Anticipate slip-ups -- they happen. But instead of letting them derail your weight loss efforts, learn from them and get right back on track. You don't have to be perfect to lose weight and be healthy. Just keep your eye on the target and keep moving forward, one step at a time. 

I was always a little overweight my whole life. I come from a family of heavy people, and when I was growing up, all of our family get-togethers were based on food. It didn't matter if it was a happy gathering or sad, people were always offering each other something to eat (and you don't want to insult anyone by not eating—it's a part of my Cuban culture). Plus, with five siblings and my mom working a lot, fast food was one of our go-tos.
“Stepping on the scale frequently makes you aware of small changes and helps you quickly react to those changes. The National Weight Control Registry, a large group of people who have successfully lost at least 30 pounds and kept it off for 5 years, found that successful ‘losers’ weigh themselves often and make adjustments accordingly. When you begin to understand that sodium, carb intake, hormones and alcohol intake can impact weight and that it isn’t possible to gain 2 pounds of fat overnight, you will begin to better understand your body. The key is to pay attention to overall trends; don’t obsess over day-to-day numbers! — Jennifer McDaniel, MS, RDN, CSSD, LD, food and nutrition expert
The concept of "diet" tea is sort of false advertising -- any unsweetened, natural tea can promote weight loss. Certain teas may act as a laxative or fat-blocker and that's why they're marketed as such. However, laxatives just clean out your colon (you've already consumed the calories). You may lose a little bit of water weight initially, but the second you drink something, it'll come back.
“Packed with important nutrients including vitamins A and C, potassium, and iron, one medium peach (only 38 calories) provides nearly 2 grams of fiber,” says Lauren O’Connor, a registered dietitian in Los Angeles, California. “A peach provides gentle laxative and diuretic properties; and thanks to itsbeta-carotenee, it also helps your skin stay fresh and bright.” (They also make the perfect after-dinner treat. Try this recipe for pomegranate and grilled peach dessert.)
Made of mostly vegetables and spices, gazpacho is full of water, fiber, and antioxidants, making it a low-calorie, filling option that can replace more caloric and fattening foods in your diet, says Maleeff. Plus, a recent Penn State study found that eating a low-calorie soup (like Gazpacho) before a meal could help you consume 20 percent fewer calories at mealtimes.

Speaking of standout breakfast foods, Greek yogurt is another option worthy of the spotlight thanks to its high-protein content. Per study in the journal Appetite, researchers from the University of Missouri compared the satiety effects of high-, moderate-, and low-protein yogurts on women aged 24-28, and found Greek yogurt, with the highest protein content, to have the greatest effect. What’s more? Probiotics in items such as yogurt and fermented foods, like pickles and sauerkraut, help good bacteria in the gut process food more efficiently. Hello, weight loss! If you want to get even more protein in your yogurt, check out Icelandic yogurts, which can have two to three more grams of protein per serving compared to Greek.
One easy trick if you're a pasta fan is to swap out white pasta for the wonderfully named courgetti (spaghetti made from spiralizing courgette). You’ll hardly notice the difference when you’re eating it, but you’ll be fuller for longer despite consuming fewer calories. When you consume fewer calories, your body can go to your fat reserves for energy, rather than just burning off the food you’ve eaten.  
Green is truly the color of health. Matcha helps to safely cleanse and purge the body of harmful elements. Chlorophyll the element that gives green tea and other plants their signature verdant color is also a powerful detoxifier, helping to eliminate both chemicals and heavy metals from the body. And because matcha is carefully shade-grown, it is substantially richer in chlorophyll than other green teas, making it a superior daily detox.

Noom helps you find and hold onto your Why while learning about other, smaller concepts that contribute to success. Self-awareness is big with Noom. The app offers short daily lessons that help you see and confront your own typical actions through introducing things like behavioral chains and triggers. If you can get past all the incessantly cheeky language (#noomerslovehashtags), it’s truly impressive how Noom deploys behavioral psychology to influence how you approach wellness.
While Samantha seems to attribute much of her success to the healthy drink, Katherine Zeratsky, R.D.N., L.D., an instructor of nutrition at Mayo Clinic, says that lowering her calorie intake was probably the biggest factor in Samantha's weight loss journey. Although caffeine in green tea can jump-start your metabolism, it wouldn't be enough to produce significant weight loss results, says Zeratsky.
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.

Fruit gets a bad rap sometimes because it naturally contains sugar. But eating fruit can help you lose weight, especially when you swap in fresh fruit for processed foods or other unhealthy snacks. You'll get a naturally sweet treat, plus reap the benefits of fiber and antioxidants. A recent study published in the Journal of Nutrition found that higher fruit consumption was associated with lower risk of becoming overweight or obese, independent of vegetable or fiber intake—though including fruit as part of a healthy diet overall is always the best strategy.
Drinking enough water can help you stay slim, too. Research from the American Chemical Society in Boston found that having two 8-ounce glasses of water before a meal while also reducing portion sizes could help you lose weight and keep it off. Not to mention, water fills you up, curbing your appetite: "In addition to slightly boosting your metabolism, drinking water before meals has been shown to help you eat less without trying," says Sass.
Why this easy fitness plan works: It's common for people who exercise regularly to do the same routine week after week. If you do the same exercises at the same intensity all the time you'll get the same results. Your body hits a plateau. This plan increases your activity level without added stress or strain to your joints. So you burn more calories without taxing your body.
A great source of calcium and important cancer-fighting compounds, broccoli also has loads of filling fiber and will set you back only 30 calories per serving. If eating this cruciferous veggie makes you bloat, try steaming it first, which makes it easier to digest while still preserving the cancer-fighting ingredients that could be lost when you boil or cook it in the microwave.

The results suggest that WL could improve anthropometric status and lipid and glycemic profiles regardless of calorie restriction and the speed of WL. However, there could be some differences between the 2 protocol types of WL in terms of impact. The WL regardless of its severity could improve anthropometric indicators, although body composition is more favorable following a slow WL. Both diets improved lipid and glycemic profiles. In this context, rapid WL was more effective.
Rise and shine—literally! Researchers from Northwest University found that people who were exposed to bright daylight earlier in the day tended to weigh less than those who didn’t get sunlight until later. So right after you wake up, open the blinds and let the sunshine in. Or better yet, step outside and enjoy your morning cup of coffee on the front porch
Another win for your morning cup of joe: Caffeinated coffee keeps things moving through the digestive tract. Since staying regular is key to a tighter-looking tummy, drinking about 8 to 16 ounces of java at the same time every day can help you stay on schedule. Remember: Sugary drinks can lead to weight gain, so skip fancy flavorings and synthetic sweeteners containing sugar alcohols, which can cause bloating.

“Research continues to support the role of a high-protein diet and weight loss, however, we don’t want to reach those protein needs exclusively with animal proteins. Plant proteins found in beans not only help us feel full and stabilize blood sugar but beans are associated with longevity. Who cares about being skinny if you die young?” —Jennifer McDaniel, MS, RDN, CSSD, LD, food and nutrition expert

The Google team looked at all their search data for 2016 to see what emerged as the top diet trends, and this buzzy acronym diet secured the top spot. Unlike most diets, it swaps counting calories for focusing on insulin levels — a measurement of your blood sugar that nutritionists love to zoom in on when evaluating a food's health merits — to ensure steady, lasting weight loss.
Set (and write down) reasonable expectations for what you plan to achieve during your challenge. “You can absolutely make a difference in 10 days,” says Brooke Alpert, RD, a dietitian in New York City and the author of The Diet Detox, but don’t expect to shed 20 pounds a la The Biggest Loser. “While actual weight loss will be around three to four pounds, you can really notice the difference in the way your body feels in about a week.”

Kimchi is a spicy Korean condiment that's made with fermented cabbage and is a great source of vitamins A, B, and C. Because it's fermented (like sauerkraut), kimchi contains tons of those good probiotics that aid the body in digestion. A recent study in the Proceedings of the National Academy of Science found that maintaining healthy bacteria in your gut can improve gut lining, which in turn could help reduce fat mass and inflammation.
Not much of a coffee drinker? Tea is also a natural diuretic, and types of herbal tea such as dandelion or fennel root can also lend a hand. In fact: When a recent study compared the metabolic effect of green tea (in extract) with that of a placebo, researchers found that the green-tea drinkers burned about 70 additional calories in a 24-hour period.
Many diets, including Atkins and the keto diet, fit into this umbrella. A typical low-carb diet limits carbs to less than 60 g daily, but this can vary, according to the Mayo Clinic. (15) In a September 2015 review published in PLOS One, people following low-carb diets saw modest weight loss — although study authors note that long-term effects of the diet require further research. (16)
Drinking herbal teas such as green tea, white tea, black tea and rooibos tea can amp up your metabolism. According to a study in the American Journal of Clinical Nutrition, green tea is more effective than other teas like oolong at promoting weight loss because of it’s high levels of catechins. (6) So if you want to lose weight fast, I recommend drinking 1–3 cups of green tea daily.
Protein is also important for preserving muscle mass as you lose weight. If you cut back dramatically on calories and drop weight too fast, your muscles can suffer. Your body starts pulling from lean tissue like muscles and organs to fuel itself, and your metabolism slows to conserve energy. That’s why super restrictive diets that have you dropping weight fast aren’t healthy over the long run.

You can do any type of cardiovascular exercise, just make sure it’s something you like – or if you have no particular preference just stay away from those actives you know you do not enjoy. Cardio is an integral part of this weight loss workout plan and it is important that you like what you are doing in order to stick with it, not just for the duration of this program, but also afterwards. You can do your cardio workouts outdoors or on cardiovascular machinery indoors. If you are carrying a lot of weight, it’s best to start with low impact exercise such as walking, swimming or using the elliptical machine. If you have access to an elliptical machine/ cross-trainer, give it a try. I love this piece of cardio equipment, as it allows you to burn as many calories as jogging/ running, but is low-impact. Exercising on the elliptical also “feels” much easier than jogging/ running, allowing you to exercise for longer and burn more calories.

Brazilian scientists found that participants who consumed three cups of the beverage every day for a week had fewer markers of the cell damage caused by resistance to exercise. That means that green tea can also help you recover faster after an intense workout. In another study—this one on people—participants who combined a daily habit of four to five cups of green tea each day with a 25-minute workout for 12 weeks lost an average of two more pounds than the non-tea-drinking exercisers.


“The best thing you can do for your belly is to give up processed foods. A study in the journal Food Nutrition Research found that our bodies burn only 50 percent as many calories digesting processed foods as they do real foods. So it’s like eating twice as much, even if the calories are the same!” — Mark Langowski, celebrity trainer and author of  Eat This, Not That! for Abs
