After all, the best diet for you is the one you can stick with (and enjoy)!
If your biggest excuse for skipping a workout is being crunched for time, Tabata is your dream come true. It’s designed to be four minutes of high-intensity interval training (HIIT) that consists of 20 seconds of all-out effort, followed by 10 seconds of rest, repeated eight times, explains Shanon Squires, an exercise physiologist and human performance lab coordinator at Colorado University Anschutz Health and Wellness Center. And you can use this protocol with different exercises, including the battle rope slams above. You’ll spike your metabolism and heart rate in four minutes, but Squires warns against making this time frame a habit if you’re trying to lose weight. “Your body will quickly adapt to that interval, and you’ll need to increase the volume or intensity to continue getting a benefit from it,” he says. To do that, Rosante suggests extending your session to 20 minutes and following the same format. Simply pick four exercises — think jump rope, squats, mountain climbers and squat jumps — then do each for 20 seconds as hard and fast as you can (while maintaining proper form, of course), then recovering for 10 seconds and 10 seconds only. Repeat for eight rounds on that one move (so, four minutes of work) before resting for one minute and moving on to the next exercise.
Men and women squirrel away fat differently, according to Harris-Pincus. On average, women have six to 11 percent more body fat than men. That extra fat typically gathers lower on the body (especially before they hit menopause) around the hips and thighs, creating a pear-shape. Men, on the other hand, tend to accumulate fat around the belly (hence, the beer gut).
The Mayo Clinic Diet is generally safe for most adults. It does encourage unlimited amounts of vegetables and fruits. For most people, eating lots of fruits and vegetables is a good thing — these foods provide your body with important nutrients and fiber. However, if you aren't used to having fiber in your diet, you may experience minor, temporary changes in digestion, such as intestinal gas, as your body adjusts to this new way of eating.
Though not always followed for weight loss per se, an anti-inflammatory diet is rich in whole foods (including fresh fruits and veggies), and low in packaged, processed ones (like french fries and pastries), so there is a chance you will still shed pounds with this approach. But usually, folks follow this diet to help prevent or treat chronic diseases, such as multiple sclerosis, rheumatoid arthritis, Alzheimer’s, and cancer. And that’s smart, considering there’s a bounty of research to support this notion. Adopting this diet is relatively simple. It isn’t focused on counting calories or carbs, or following any sort of specific protocol. Instead of constantly thinking about the quantity of food you are eating, an anti-inflammatory is all about prioritizing the quality of what is on your plate.
Motivation and encouragement: Every person has different needs when it comes to what motivates them to succeed. Think about how you have met other important goals, or quit bad habits in the past. Would you be more likely to succeed using social media, in-person meetings with strangers or acquaintances, or expert counseling using text messaging, phone calls or email?
That’s because it theoretically causes a mild ketosis (yep, the basis of the keto diet), which is a fat-burning state that should make you feel less hungry. The key in being successful with a low-carb diet (especially if you’re used to a more high-carb lifestyle) is to compensate for those lost carbs with protein-rich foods, says Dr. Cheskin. That way, your volume of food stays the same, but you’re doing it healthfully rather than in a way that exacerbates your weight gain.
The Paleo Diet (Free) is not intended to be a weight loss diet, per se, but rather a way of eating that is meant to be permanent. In many Paleo protocols, there is a strong emphasis on grass-fed or organic foods, which can be pricey and may not be readily available to some, but other programs recommend that you just purchase the highest quality of food you can afford. Exercise is strongly encouraged. You don't count calories; you just eat until you're satiated.
Created in 2003 by cardiologist Arthur Agatston, this low-carb diet features three phases. The first phase is the most restrictive, limiting carbs such as potatoes and rice. Each subsequent phase becomes more lenient, and the diet emphasizes lean protein, unsaturated fats, and low-glycemic carbs such as nonstarchy vegetables. South Beach promotes lasting lifestyle changes, according to the Mayo Clinic. (21)
It’s time to focus on your lentil health. In one four-week Spanish study, researchers found that eating a calorie-restricted diet that includes four weekly servings of legumes aids weight loss more effectively than an equivalent diet that doesn’t include beans. Those who consumed the legume-rich diet also saw improvements in their “bad” LDL cholesterol levels and systolic blood-pressure. To reap the benefits at home, work lentils, chickpeas, peas and beans into your diet throughout the week.
But just because belly fat comes off a bit more easily doesn’t make it less dangerous. In fact, it’s the exact opposite. “Belly fat is unfortunately the most dangerous location to store fat,” says Dr. Cheskin. Because belly fat—also known as visceral fat, or the deep abdominal fat that surrounds your organs—is more temporary, it’s more active in terms of circulating in the bloodstream. That means it’s likely to raise the amount of fat in your blood (known as blood lipid levels) and increase your blood sugar levels, which as a result raises your risk of heart disease and type 2 diabetes.
HIIT gives you a well-rounded workout while burning a ton of fat and calories. “HIIT workouts can vary greatly, from 500 calories per hour to 1500-plus calories per hour for an 180-lb man,” says Ryan. “HIIT workouts are great because of the intensity of each exercise as well as the variation of exercises and reps.” Pairing any body-weight movement with a weighted movement and a traditional cardio element and you have the perfect recipe for an amazing fat-burner.
Switch to Lighter Alternatives. Whenever you can, use the low-fat versions of salad dressings, mayonnaise, dairy products, and other products. "You can trim calories effortlessly if you use low-fat and lighter products, and if the product is mixed in with other ingredients, no one will ever notice," says Magee. More smart substitutions: Use salsa or hummus as a dip; spread sandwiches with mustard instead of mayo; eat plain roasted sweet potatoes instead of loaded white potatoes; use skim milk instead of cream in your coffee; hold the cheese on sandwiches; and use a little vinaigrette on your salad instead of piling on the creamy dressing.
Weight Watchers – the diet your nan used to follow – is no more. In 2018, the company had a re-brand, with the new WW branding signalling a move away from diet culture and into the wellness-sphere – hint: WW now stands for ‘Wellness that Works’. ‘We are not classed as a diet,’ a member of the press office team tells WH. ‘It is a lifestyle change – a healthy living programme that encompasses food, activity and mindset.’
Many people dread the thought of New Year, knowing they’re going to try and commit to a weight-loss plan or diet to shed the extra pounds accumulated during the festive season. Last year, a YouGov poll revealed that 37% of Americans decided they wanted to either eat healthier or exercise more and it’s unlikely those statistics will change much going into 2019.
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.
Lose fat with high-intensity interval training (HIIT). If you're trying to lose weight fast, HIIT training can super-charge your metabolism for upwards of 24 hours after exercising. This means your body will continue burning calories long after you've ended your workout. HIIT burns more calories in less time than steady-state cardio. In one study, researchers looked at two groups, one running for 30 to 60 minutes three times per week, the other doing four to six 30-second treadmill sprints, resting for four to six minutes between each sprint. After six weeks, it was found that the group doing HIIT training lost more weight.
This popular plan recently underwent a rebranding to create a more balanced program, changing its four-phase approach with the help of a science advisory board. The Atkins Diet is still low-carb, but you won't be chowing down on steak and eggs all the time to promote weight loss. Lean protein is still key, but there's more of a spotlight on fiber, fruit, vegetables, and healthy fats.
