High-intensity interval training—HIIT—has gained a reputation as an efficient way to get fast results. This workout involves short (30 seconds to five minutes), vigorous bursts of activity interspersed with periods of rest for maximum results. Incorporating HIIT into your strength training may offer even more results, according to a recent study by the American Council on Exercise—the results suggest the combo may be even more effective in burning fat fast.

Fat metabolism is the most efficient way to produce energy, allowing you to go and go and go without burning through a ton of calories. But efficiency is the enemy of fat loss. To lose body fat, you want to churn through calories—calories from carbs, calories from fat, calories from anything—and you get there through carb metabolism. “The more energy-demanding the work, the more likely you are to lose body fat,” Zimmerman explains.
If you need to reduce calories, start by reducing your fat intake. Keep your carbohydrate and protein consumption as high as possible for as long as possible to maintain your energy. Just don't let your total fat intake dip below 10 percent of your total daily calories. Having fewer fats than that in your diet can harm your performance, recovery, muscle maintenance, and testosterone production.

Unsurprisingly, the results showed that nothing had happened to the weight of the women receiving calcium or the placebo. However, the group which took the multivitamin lost more weight – about 3 kg more – and improved their health markers. Among other things, their basal metabolic rate (the rate at which the body burns calories when at rest) increased.


Over the past few years it has become clear that weight is an important health issue. Some people who need to lose weight for their health don't recognize it, while others who don't need to lose weight want to get thinner for cosmetic reasons. We understand that in some ways your weight is different from, for example, your cholesterol level or your blood pressure, because you can't see what these are by looking at someone. Many patients have had health care providers who approached their weight in a less-than-sensitive or helpful manner. Some patients may have had health care encounters in which they felt blamed, but not helped. Successful weight management is a long-term challenge.
You can get an estimate of how many calories you burn every day by using this calorie calculator. When you fill out the form, do your best to pick the level of activity that matches what you do on an average day. If you say you're more active than you really are, you'll end up with a lot more calories than your body needs, and you'll start gaining weight. For the moment, choose "maintenance" as your goal.
Weight training is the ultimate way to burn calories fast. "A pound of muscle burns up to nine times the calories of a pound of fat," explains Richard Cotton, M.A., chief exercise physiologist for myexerciseplan.com. Weight training increases your resting metabolic rate, which is the number of calories you burn while sitting on your butt. What's more, it gives your metabolism an added boost after you exercise, staying in overdrive for up to two hours after the last bench press, according to a study published in Medicine & Science in Sports & Exercise. Strapped for time? Try these quick moves: squats, bench step-ups, lunges, push-ups, pull-ups and planks. In a pinch, just do single sets of 10 for each exercise — you'll get optimal results for the time invested.
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.
If your fitness goals include a flatter belly and stronger core, you're going to need a solid plan, expert guidance, and a little outside motivation. Our 30 Days to a Flat Belly plan has all three! This comprehensive workout plan will give you results you want without a pricey gym membership; you can do these workouts anywhere — and they're all 30 minutes or less.
Another misconception about HIIT is that it will cause muscle loss. This is just not true either. This myth got started because a higher amount of calories burned during HIIT will come from stored amino acids (muscle tissue) when compared to lower intensity cardio. As long as HIIT sessions are kept to a short duration muscle loss not be a problem. In fact, muscle growth and muscle retention are increased due to the effects HIIT has on anabolic hormones. Just one 10-15 minute session of HIIT can increase testosterone and growth hormone levels for hours after the workout has ended.
Creatine phosphate is stored within muscle tissue and is a source of stored energy used during short bouts of high-intensity exercise. The creatine phosphate stored in your muscle tissue assists your body’s main energy source used during the first few seconds of performing any type of exercise, called adenosine triphosphate, or ATP. Your body uses ATP for energy during the first five seconds of any exercise, such as lifting a weight, and stored creatine phosphate is then oxidized to produce an additional five to eight seconds of energy. This entire process lasts for about 15 seconds. Creatine supplements help increase the amount of creatine phosphate stored in your muscle tissue allowing you to lift more weight for more reps.

Soup -- we're talking broth-based, not creamy -- has a lot going for it. It's full of water, which fills you up with the fewest possible calories. It's hot, which prevents you from eating too much. Have it before a meal, and soup can take up space that might have gone to higher-calorie foods. You can also make a satisfying, low-calorie meal out of soup alone by adding chicken, fish, cut-up vegetables, or beans.


There’s mounting evidence that our body’s natural internal clocks, or circadian rhythms, drive a lot of our biological processes, including weight maintenance. They tend to sync up with daylight. That could be why studies have shown that shift workers tend to have a higher rate of obesity and weight gain—their body clocks are out of sync. One study even found that a third of people who experienced an interrupted sleep cycle for less than two weeks became prediabetic; all of the poor sleepers saw markers for the risk of obesity and type two diabetes climb.

Do this: Limit your total carbs on two consecutive days every two weeks or so to less than 100g per day. This will require you to know how many grams of carbohydrates are in the foods you eat and have the discipline to be very strict on your intake. Your diligence will be rewarded with a noticeable difference in body fat. After two days, you can return to a more normal, though not excessive, carb intake.
We also love yoga, hula-hooping (yep, great for the abs) and the good standby “Abs of Steel” videos, and trust me the outfits in the 1990’s video will increase the cardio aspect just from laughter alone! There are also a slew of videos online, find one you love and can stick to every few days and you’ll be toning as you shed the unwanted belly fat.
People often think that low-intensity exercise, in which your body taps into fat metabolism, is the most efficient way to lose body fat. Some cardio machine displays even claim that you’re in the fat-burning zone when your heart rate is low and that you exit the zone once your heart rate rises. Physiologically, the second part of that statement isn't true. 
The 2003 research indicated that exercise is a top weapon against visceral fat, backed up by a 2011 study which found that aerobic exercise is basically a magic bullet. Aerobic exercise is known to most people as cardio — activities such as running and cycling, as opposed to resistance training (where you lift heavy stuff around). While participants in the study worked fairly hard (jogging 20km per week at a high intensity), the researchers said lower-intensity but longer workouts should have similar benefits.

Do more HIIT: High intensity interval training (HIIT) is as close to a magic pill as we have (except it involves a whole lot more work than just swallowing a capsule—sorry). Not only does it surge your body to max intensity during the workout, but because you’re working so hard, your body can’t deliver enough oxygen in the moment, explains personal trainer Jeremey DuVall. Your muscles accumulate a “debt” of oxygen that then has to be repaid post-workout. This throws your body into a phase of fat burning for hours after you’re done sweating, known as post-exercise oxygen consumption, or EPOC. Plus, super intense circuits like this activate muscle-building hormones like growth hormone and IGF-1, he adds.
