The authors wanted to compare low-fat vs. low-carb diets, but they also wanted to study genetic and physical makeups that purportedly (their word) could influence how effective each type of diet will be for people. Previous studies had suggested that a difference in a particular genetic sequence could mean that certain people will do better with a low-fat diet. Other studies had suggested that insulin sensitivity may mean that certain people will do better with a low-carb diet.
Fat: It’s the stuff that gives ice cream its creaminess and pizza its dreaminess. In the right places and in the right amounts, fat is the stuff that makes life worth living. But when your curves start crashing over the bulwark of your beltline, it’s time to start thinking about how to lose body fat. Not losing weight per se, but burning off the soft, jiggly stuff and replacing it with firm, lean muscle. Too much fat isn’t just an aesthetic issue, it’s a health issue: belly fat, in particular, is linked to everything from heart disease and diabetes to liver failure, depression and dementia.
In the UK, up to 5% of the general population is underweight, but more than 10% of those with lung or gastrointestinal diseases and who have recently had surgery. According to data in the UK using the Malnutrition Universal Screening Tool ('MUST'), which incorporates unintentional weight loss, more than 10% of the population over the age of 65 is at risk of malnutrition. A high proportion (10-60%) of hospital patients are also at risk, along with a similar proportion in care homes.
If you want to get a six-pack, you should cut out sugary beverages and replace them with diet versions, right? Wrong. Recent studies have found an association between the consumption of diet sodas and a wider waist circumference. What’s more, diet soda drinkers have a higher percentage of belly flab than those who don’t sip the beverage, a study in the Journal of the American Geriatrics Society found. Why? Researchers think diet soda drinkers may overestimate how many calories they’re “saving,” then overeat.
Creatine, a potent muscle-builder, may also help you burn fat. The muscle added during creatine use increases your resting metabolic rate, stoking your fat-burning furnace. This is critical during a fat-loss phase, when low calorie intake can compromise your muscle mass and lower your metabolic rate. Begin with a five-day loading phase: 15-20g daily, divided into 3-4 equal doses. After that, take 3-5g of creatine per day with a meal post-exercise.
5. Start with one small change. "I realized that a lot of sugar and calories that I consumed came from drinks, so I challenged myself to drink only water—no sugary drinks!—for 30 days. After just one successful week, I decided to add another challenge: to cut back on the carbs I was eating. When I did eat bread, I switched to wheat bread and when I wanted rice, I used brown rice."
Barley got its hunger-fighting reputation after Swedish researchers found that eating barley or rye kernels for breakfast kept blood sugar on an even keel. That's because the carbs in barley and rye kernels are "low glycemic index," meaning they raise blood sugar more slowly than some other carbohydrate foods. This helps you avoid a spike, and then a drop, in blood sugar, which can leave you feeling famished.
A 2012 study in the Journal of Functional Foods found that people who drank one and a half cups of green tea enriched with a total of 609 milligrams of catechins (a group of antioxidants that have been shown to help burn fat cells) every day for 12 weeks lost almost 16 times as much visceral fat as those who consumed green tea without the added antioxidants. To achieve similar results with store-bought green tea, you’ll need to brew two to four cups daily (many varieties can contain 160 to 470 milligrams of catechins per cup).
A common misconception amongst many female fitness enthusiasts is that steady-state cardio in the "fat burning zone" is ideal for weight loss. Spending two hours on the treadmill may seem like it'll get you bikini-worthy bod—more minutes, more calories, right? However, while steady-state cardio has many benefits, it isn't the most effective way to reduce body fat.
The final possible culprit behind stubborn weight issues may be the stress hormone, cortisol. Too much cortisol will increase hunger levels, bringing along subsequent weight gain. The most common cause of elevated cortisol is chronic stress and lack of sleep (see tip #10), or cortisone medication (tip #9). It’s a good idea to try your best to do something about this.
It's easy to overdo it when you're eating something delicious — and that's why it's good to focus on foods that will force you to slow down. "Slowing down can help you check in with your hunger levels. For that reason, I love snacking on 100-calorie packs of in-shell pistachios," Gorin says. "Shelling the pistachios helps you slow down your snacking, and the shells leave a visual cue to remind you of how much you've eaten. Because you're more in tune with what's gone into your mouth, you may be less likely to have extra servings." In one preliminary study, people snacking on in-shell pistachios ate 41% less calories than those who ate the shelled version.
Replace your weekly cardio session with circuit resistance training to whittle your middle. “High-intensity circuit training with dynamic movements is one of my favorite ways to build muscle and burn fat all over the body, says Rich. “There is no possible way to spot-reduce fat, so it’s important to train the entire body to lose fat overall. Performing moves like burpees, jump squats, mountain climbers and fast push-ups are great examples. If you have 40 minutes to work out, do twenty minutes of cardio and twenty minutes of circuit resistance training. You’re sure to see the difference in your body.”

“For some people, it’s knowing, ‘Typically I eat a whole sandwich,’” says Gagliardi. “‘Now, I’m going to make the decision to eat half a sandwich at lunch and save the other half for my dinner and essentially cut my calories in half. And they feel good about that. They’re not having to do math.” To get started, check out these 25 simple ways to cut 500 calories a day.
Another popular mainstream diet, Dr. Barry Sears's plan is considered to be one of the first in the recent wave of "anti-inflammatory" plans. It sets you up for success by calibrating your plate to be a third protein and two-thirds carbohydrates (not starchy ones like potatoes, think colorful vegetables instead) with a little bit of MUFAs, or monounsaturated fatty acids (the good-for-you kind ) in the mix.
Why does this popular plan work? For one thing, it pushes wildly healthy staples to the forefront (think: nuts, vegetables, fruit, olive oil). For another, it's simply delicious, thanks to it's focus on fresh, simply prepared dishes like grilled fish with lemon and whole wheat pita with hummus. Science agrees: One meta-review of 16 studies, found the eating M.O. helped those on it lose an average of 8.5 pounds.
Without alcohol, they’re less fattening, right? Yes and no. It’s true that alcohol adds calories, but so do the ingredients you’re swapping in. Virgin margaritas, pina coladas, and daiquiris are made with fruit juices and sometimes syrups, which have loads of calories and sugars. Instead, Amidor recommends sticking with alcohol—in 5 ounces of wine or a 12-ounce light beer. Here are the weight-loss motivation techniques 22 real people used to lose weight.
"No matter how bad off you are when you start, you can still be successful," says Dawn Sabourin, 50. "Don't look at how far you have to go because you will become overwhelmed and quit." And playing the long game can help you feel more in control. "Accept where you are starting and take one step at a time in the right direction. They will build, as will your confidence and success."

When fat loss is the goal, planning a good mix of workouts is key. Gary suggests incorporating a combination of strength training, high- and moderate-intensity cardio and something to help relax the muscles. “I’ll train my clients hard on the strength training and high-intensity cardio side of things, then suggest they get to a good yoga or pilates class and fit in a run or sign up for a spin class,” he says.
Fennel, peppermint, and ginger have all been shown in research studies to have calming effects on the belly. They work by enhancing digestive enzymes so your food gets moved through your system faster. And faster-moving food means a flatter tummy. In addition, peppermint reduces cramping and gas, ginger helps with nausea and inflammation, and fennel is a diuretic to help you stop retaining water.
