The following workouts are simple to follow, just not very easy to do. For each major muscle group, after following the HIIT 100s protocol on your first exercise, you'll do three more sets to failure of the same exercise using your 10-rep max (10RM). Of course, after doing 10 sets of 10 reps, you'll no longer be able to complete 10 full reps with your 10RM weight—probably more like 5-7 reps. On the third set, you'll do a dropset with the same weight you used for HIIT 100s (50% of your 10RM) and do as many reps as possible.
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.
“Do what works for you,” Langer says. “And if something doesn’t, change it. There’s a million other ways to go about it. There are no absolutes in nutrition.” Case in point: In a 2018 JAMA study, when more 600 adults who were classified as overweight followed a low-fat or low-carb eating plan over the course of 12 months, everyone lost about the same amount of weight.
Considering that only 1 in 10 Americans meet their produce requirements, it’s pretty safe to say you need to eat more veggies. And no matter what food philosophy you subscribe to, veggies are a big part of the program. Vegetables have a lot going for them: They fill you up for very few calories, and they flood your body with the nutrients it needs to fight diseases, like heart disease, type 2 diabetes, and some cancers.
For those of you who aren't familiar with HIIT, it involves intervals of high-intensity exercise (such as running at 90% of your max heart rate) followed by low intensity (walking at a moderate pace) or complete rest. This is in sharp contrast to the typical steady-state cardio most people do at a moderate intensity, such as walking on a treadmill at 60-70% of their max heart rate.
It’s true that a caloric deficit—burning more calories per day than you take in—is a requisite of weight loss. But creating a deficit doesn’t have to (and shouldn’t) involve deprivation. That goes for calories, carbs, sugar, fat, or any other commonly demonized nutrient. “No one food is responsible for your weight,” Langer says, explaining that a good vs. bad mentality sets people up for disordered eating and exercise habits. In fact, caloric deprivation increases how the brain responds to food, setting you up for binge-eating down the line, according to research from the Oregon Research Institute.
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.
Eat Breakfast Every Day. One habit that's common to many people who have lost weight and kept it off is eating breakfast every day. "Many people think skipping breakfast is a great way to cut calories, but they usually end up eating more throughout the day, says Elizabeth Ward, MS, RD, author of The Pocket Idiot's Guide to the New Food Pyramids. "Studies show people who eat breakfast have lower BMIs than breakfast-skippers and perform better, whether at school or in the boardroom." Try a bowl of whole-grain cereal topped with fruit and low-fat dairy for a quick and nutritious start to your day.
"When we’re lacking in sleep, our body’s hormones get thrown off balance which can impact our hunger levels the next day. We all have two hormones that affect our appetite: ghrelin and leptin. When we don’t get enough sleep, our ghrelin levels (the hormone that makes us feel hungry) rise, and our leptin levels (the hormone that makes us feel full) drop. This means that when we’re awake, we tend to eat more but feel less satisfied. Try going to bed a little earlier than usual to avoid this imbalance and remember to remove any distractions that might prevent you from nodding off."
