When most people think of HIIT they think of it as applicable only for cardio, yet it can also be used in weight training. After all, weight training itself is a form of HIIT—you do a set with all-out effort, rest, then do another set, rest, and repeat. Resting two to three minutes between sets, however, is too long for a training session to be considered an effective form of HIIT. But all you have to do is shorten rest periods and you're doing a kind of HIIT that burns fat.
Your body needs a certain amount of essential vitamins and minerals to function properly. What happens when you don’t get enough of them? What happens when you eat too little food, or when the food you eat isn’t sufficiently nutritious? Perhaps our bodies catch on and reply by increasing hunger levels. After all – if we eat more, we increase the chances of consuming enough of whatever nutrient we are lacking.
If you eat a carbohydrate-rich meal (lots of pasta, rice, bread, or French fries, for example), your body releases insulin to help with the influx of all this glucose into your blood. As well as regulating blood sugar levels, insulin does two things: It prevents your fat cells from releasing fat for the body to burn as fuel (because its priority is to burn off the glucose) and it creates more fat cells for storing everything that your body can’t burn off. The result is that you gain weight and your body now requires more fuel to burn, so you eat more. Since insulin only burns carbohydrates, you crave carbs and so begins a vicious cycle of consuming carbs and gaining weight. To lose weight, the reasoning goes, you need to break this cycle by reducing carbs.

HIIT was originally developed by track coaches to train runners, but it has crossed over to the fitness industry due to its fat-burning benefits confirmed many times over in scientific studies (see "HIIT Findings"). A lot of these studies found that subjects performing HIIT burned significantly more body fat—and in less time—than those who did steady-state cardio programs.
What is it about the keto diet that’s made it so popular recently, and why is Lauren considering it? It’s all about trimming fat. The whole point of the diet is to get your body into a state of ketosis. That’s when your body starts releasing ketones that burn stored fat for energy instead of carbs. The issue that a lot of people encounter with it is that it can take a while to get your body into that state of ketosis. A supplement like K Shred might be able to give your body a little push so that you can start burning fat sooner than by dieting alone.
If you’re routinely skimping on the recommended seven to nine hours, or you have difficulty falling or staying asleep, it’s time to get serious about your bedtime rituals. Your better-sleep strategy includes: limiting caffeine past the early afternoon; sticking to alcohol caps of one drink for women, two for men (since alcohol can interfere with the quality of your sleep); and staying off the phone and iPad within an hour of bedtime.
This drug is an injected variant of a satiety hormone called GLP-1. It slows down how quickly the stomach empties and tells the brain that you don’t need to eat yet – a great idea for losing weight. As a bonus this drug works fine while one is on the keto diet and it works even better with intermittent fasting – for a rapid weight loss with no hunger.
What does a HIIT workout look like? You could jog for two minutes, sprint for one minute, jog for two minutes, sprint for one minute. Or you could do a HIIT workout on a bike, or by running up stairs and then jogging back down. The key is that you go relatively all out for a short period of time, then recover by maintaining a moderate level of intensity, then go again.

Choose Liquid Calories Wisely. Sweetened drinks pile on the calories, but don't reduce hunger like solid foods do. Satisfy your thirst with water, sparkling water with citrus, skim or low-fat milk, or small portions of 100% fruit juice. Try a glass of nutritious and low-calorie vegetable juice to hold you over if you get hungry between meals. Be careful of alcohol calories, which add up quickly. If you tend to drink a glass or two of wine or a cocktail on most days, limiting alcohol to the weekends can be a huge calorie saver.
One thing that might help you move away from food rules based on restriction is mindful eating, which is a way of eating that is centered on being present and engaged not just with your food, but why you’re eating it, and how your body feels. Mindful eating can help people learn how to eat based on what they want and need, as opposed to what they feel they should or shouldn’t eat. Mindful eating isn’t a weight-loss diet, but it can help change your orientation to food and food “rules.”
Real talk: It could take weeks or months to see the metabolic effects of exercise on the scale, and even then, building muscle, which is denser than body fat, could lead to weight gain. "Do what you like because it’s good for you," Dr. Seltzer says, noting the way exercise is awesome for your heart, mental health, and more—and that not all measure of progress can be seen on the scale.
Fiber works its weight loss magic in multiple ways. It helps you feel fuller, longer so eating fiber-rich foods is the dieting equivalent of working smarter, not harder. Plus, fiber takes a long time to digest, so fiber-rich foods don’t cause spikes in blood sugar that can send your insulin levels soaring. On the other hand, when you eat the so-called bad carbs (the refined or sugary ones that lack fiber), you may wind up with an insulin response that promotes fat storage. The takeaway: More fiber equals less fat storage.

This two-week program mandates the use of heavy compound exercises to start every weight workout. By keeping heavy training in your program, you’ll force your body to keep its natural production of growth hormone (GH). High GH, which peaks while you sleep, is a key player in the fat-burning process. Then, by targeting individual body parts with Tabata-style work, you’ll increase local blood flow to working muscles. On each Tabata exercise, start with a weight you can handle for 12–15 reps. As the work drags on, your rep counts will fade. Pause only when needed, and perform partial reps if necessary to keep going the entire 20 seconds.


There’s one caveat, though: Don’t train your abs. (You’re welcome.) While you need to work abs most weeks, the point of workouts at this stage is to get the muscles that pump up well to swell further with increased glycogen storage. Since abs don’t get pumped like biceps or shoulders, it doesn’t make sense to drive glycogen into them—in fact, doing so can cause them to inflate too much, blurring definition.

I am a 50 year old male and I consider myself to be in pretty good shape. I've been body building for about 3 years and I'm around 13% body fat. I started this workout and could only get through 2 rounds of the cardio after each weight training session. You younger guys and gals might be able to get through it, but it wore my butt out! Hopefully I can get through 3 cardio sessions next week. My goal is to get to 10% body fat within the next 12-16 weeks.
You might have heard the term ‘middle-age spread’. This means, as women progress towards their middle years, the ratio of body fat increases compared to the body weight. During menopause, when the levels of estrogen go down, and the amount of androgens or male hormones increase, then there is an increased risk of fat accumulation in the waist. Hormones actually regulate the fat concentration in the body, and your figure depends entirely on it!
If we had a dollar for every well-intentioned person who's centered his or her fat-burning efforts around low- to moderate-intensity cardio sessions, we could make Fort Knox our summer retreat. This "I'm trying to lose weight, so I'm just doing cardio" attitude has become epidemic, as people waste countless hours on ellipticals, treadmills, and stationary bikes, with very little to show for it. The results they're after, of course, are washboard abs and an overall leaner physique, which is best accomplished through high-intensity lifting at appreciable volumes.
If you’re routinely skimping on the recommended seven to nine hours, or you have difficulty falling or staying asleep, it’s time to get serious about your bedtime rituals.

On HIIT 100s sets during Weeks 1-3, when rest periods are 30 seconds or more, perform the first three sets of 10 as fast and explosively as possible. This will help build more muscle power and strength, despite using such light weight. On Sets 4-6, keep the movement slow and controlled, focusing on the contraction and squeezing each rep at the top for one to two seconds. This helps establish a strong mind-muscle connection, which is critical for muscle size, shape, and separation.
Instead of satisfying your sweet tooth with some refined sugar, turn to berries and enjoy a slimmer waistline in no time. Berries are loaded with antioxidants, which can help reduce inflammation throughout the body, and research from the University of Michigan reveals that rats given a cherry-rich diet shaved off a significant proportion of their belly fat when compared to a control group. Berries like strawberries, raspberries, blueberries, and blackberries are also loaded with resveratrol, an antioxidant pigment that has been linked to reductions in belly fat and a reduced risk of dementia, to boot.
