You're probably familiar with high-intensity interval training (HIIT). When it comes to cardio, HIIT is definitely the best way to strip off body fat, to the extent that there's literally no reason to hop on a treadmill and run at a steady pace for 30 or more minutes unless you're an endurance athlete. And if you're reading this magazine, chances are you don't desire the physique of a marathoner.
Three sets of one or two more exercises and you'll be done with that muscle group for the day. Rest between all sets following the HIIT 100s exercise is limited to one minute to maximize fat burning. You'll follow the muscle group-specific weight training with one last dose of HIIT 100s using a full-body exercise such as barbell or dumbbell cleans; kettlebell swings; barbell or dumbbell deadlifts; barbell, dumbbell, or kettlebell snatches; or my own unique lift known as the dead/curl/press.
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.
This could be because the body increases insulin secretion in anticipation that sugar will appear in the blood. When this doesn’t happen, blood sugar drops and hunger increases. Whether this chain of events regularly takes place is somewhat unclear. Something odd happened when I tested Pepsi Max though, and there are well-designed studies showing increased insulin when using artificial sweeteners.
"It’s easy to become impatient and frustrated when you’re trying to lose weight and haven’t seen the results yet. But be realistic – you won’t see the affect overnight. Your brain’s wiring plays a huge part in resisting changes in lifestyle, and it takes time to establish new habits – up to 12 weeks. Stick with it for at least eight weeks and you should notice a change."
For example, you might not realize just how much you eat when you go out to happy hour with friends. But if you take the split second to take a step back and make yourself aware of that fact, you’re more able to make a healthy decision. “The awareness and then planning and coming up with strategies for what else I can be doing—that might give me the same benefit of eating those comfort foods that make me feel better,” says Gagliardi.
That’s because women tend to store more temporary fat in their bellies. “The fat stores are gained and lost,” says Lawrence Cheskin, MD, chair of the department of nutrition and food studies at George Mason University and director of the Johns Hopkins Weight Management Center. “By and large, belly fat comes off easier in the sense that it comes off first. That’s where a good amount of the fat is lost from.”
Don’t let extra hours lounging in bed stand between you and a flatter belly. While getting enough sleep can help boost your metabolic rate, sleeping in may undo any benefit you’d enjoy from catching a few extra winks. One Obesity study reveals that late sleepers who snoozed past 10:45 in the morning ate nearly 250 more calories over the course of the day, despite eating half as many fruits and vegetables as their early bird counterparts. Even worse, they chowed down on more salty, sugary, and trans-fat-laden fast food than those who woke up earlier. If you happen to head out of the house early, you’re in for an additional metabolic boost; researchers at Northwestern University have found that people exposed to just a short period of early morning sunlight had lower BMIs than their late-waking counterparts.
Losing weight isn’t necessarily a matter of meat vs. plants or carbs vs. fats. Repeatedly, studies suggest you can lose weight with a number of different approaches, including the ketogenic diet, intermittent fasting, and WW (formerly known as Weight Watchers). Truth be told, losing weight is much easier than keeping it off. The last decade of research on weight loss points to the fact that once you lose weight, your body is in a battle with biology. It’s an unfortunate irony, but studies show that as you drop pounds, your levels of “I’m hungry” hormones increase, while your “I’m full” hormones decrease. At the same time, your body physically needs less fuel to operate your smaller size. It’s not an easy battle, but it isn’t impossible; you can march on. Here’s what we’ve learned about weight loss, and what you can do to take charge of your weight this year.
"Your body needs a healthy balance of exercise and rest. Doing too much prevents the body from shifting excess fat. Exercising without rest can impact our levels of the steroid hormone cortisol and cause an increase of stubborn fat stored in the belly. Not allowing your body to recover can increase the risk of injury too, so make sure you factor in rest days to your plan."
