High intensity interval training, or HIIT, is a type of training that involves short bursts of high-intensity intervals of exercise combined with lower-intensity intervals. One example is all-out sprinting for 30 seconds between 60-second jogging sessions. One workout would involve five to 10 of those high-intensity cycles. This type of workout is designed to burn large amounts of fat in a short period of time.
Frozen meals are super-convenient. They’re cheap, easy to throw in your bag as you’re running out the door, and take just three minutes to cook. While your 300-calorie Lean Cuisine may seem like a waist-friendly option, it’s not. Most frozen meals are loaded with sodium—as much as you should eat over a full day, not just in one meal—and lots of other synthetic additives. Sodium packs on water weight, as the body needs to maintain a balance in the body, and when you’re thirsty, you could reach for a sugary beverage, which adds hundreds of more calories. Salt also makes food taste better, prompting you to shovel more of it in your mouth. Another problem with frozen meals is they frequently lack sufficient fiber to keep you full, so you’re likely to find yourself sneaking back into the kitchen shortly after you’ve eaten. If you must eat a frozen meal, consider adding a serving or two of frozen vegetables to boost the fiber and fullness quotient and dilute the sodium.
Instead of ditching your diet and the pursuit of better health, it’s a good idea to ditch your idea of what healthy looks like. Lately, movements, like body positivity, health at every size and anti-dieting, have sparked a meaningful conversation about healthy bodies, and guess what? They come in all shapes and sizes. The number on the scale is just one indicator of health; your lab work (cholesterol and blood glucose levels, for instance), blood pressure levels, and measures of physical fitness are other factors. So is your emotional health.
Although you won't be able to completely transform your body or even lose more than a few pounds in a month, you can jump-start your weight-loss journey and be well on your way to achieving your goals. Just be mindful that while you can lose weight in a month, you can't specifically target your belly; there's no such thing as being able to spot-reduce fat (your body decides where the fat comes from - yay, genetics!). We tapped registered dietitian and ACSM-certified personal trainer Jim White, who owns Jim White Fitness and Nutrition Studios and helps clients reach their weight-loss goals, for insight on how to lose belly fat in 30 days.
After your last training session (Wednesday, in this example, two full days before Saturday’s event), eat two to three grams of carbs per pound of body weight for the rest of the day. If you train at night and it’s hard to eat enough carbs before bed, you can split up the total and eat the rest of the carbs on Thursday night. Insulin sensitivity remains high for 48 hours post- workout, so glycogen will still go to your muscles. Otherwise, on Thursday, go back on the diet prescribed in Step 2.
Try on clothes and pay attention to the fit. A great way to identify weight loss is if your clothes become too big or fit loosely. Stay positive, even when the numbers on the scales increase. When building muscle, you may experience weight gain -- lean muscle tissue -- but as long as your body fat percentage is decreasing, you’re on the right track.
If you follow food trends, you might think you have to fall in love with cauliflower and kale to reap all the rewards that veggies offer, but that isn’t the case. Be it broccoli, sweet potatoes, carrots, red peppers, cabbage, spinach, or any other vegetable, the idea is to eat a variety of them and find plenty of ways to enjoy their goodness. So if you just can’t stomach steamed Brussels sprouts, try them roasted, or give sautéed Brussels sprouts a try. If raw zucchini isn’t your thing, see if you like it spiralized into noodles or grilled on a grill pan.
When you drink liquid carbs, like the sugar in soda, your body doesn't register them the same way as, say, a piece of bread, according to a review of studies published in Current Opinion in Clinical Nutrition & Metabolic Care. That means, even though you're taking in calories, your fullness cues aren't likely to signal that you're satisfied once you finish off a can. And that can lead to consuming more overall.

There’s also the impact fiber has on your gut health. By now you’ve likely heard of the microbiome—the trillions of bacteria that live in your digestive tract. It turns out that a predominance of certain strains of bacteria may encourage inflammation and weight gain, and eating fiber-rich foods can favorably shift this balance. While it’s too soon to say that changing your microbial makeup will prompt weight loss, it’s likely to send a “hey, stop gaining weight,” message.
Since it was established in 1994, The National Weight Control Registry (NWCR) in the United States, has tracked over 10,000 individuals who have lost significant amounts of weight and kept it off for long periods of time. The study has found that participants who’ve been successful in maintaining their weight loss share some common strategies. Whatever diet you use to lose weight in the first place, adopting these habits may help you to keep it off:
The researchers hypothesize that participants who abstained from animal products dropped significantly more pounds since plant-based foods include loads of filling fiber and slow-to-digest complex carbs. Though more research is needed to confirm these results, the study authors write, "Vegetarian diets appeared to have significant benefits on weight reduction compared to non-vegetarian diets."

Carbs aren’t evil -- but sugar might be. “The concept of carbohydrates has really gotten such a bad reputation, and we need to understand that there are complex carbohydrates and ancient grains that can really help us not only lose weight, but increase satiety so we stay full longer and want to eat less. It actually decreases the cholesterol and stabilizes the blood sugar, and all of these things are a really important part of a weight loss program,” said Dr. Suzanne Steinbaum, an American Heart Association volunteer medical expert. These “good” carbs include whole grains, vegetables, fruits and beans; the refined carbs (including refined grains and starches like white bread, white rice, pasta and mashed potatoes) should be consumed in limited amounts. “They are high in simple sugars, and that’s what adds weight,” said Dr. Steinbaum.
Weight loss ultimately comes back to the concept of calories in, calories out: Eat less than you burn and you’ll lose weight. And while it’s possible to lose water weight quickly on a low-carb diet, I certainly wouldn’t advocate for it. The diet itself can trick you into thinking that this eating style is working — when really, you might gain back what you lost as soon as you eat carbs again. That can feel incredibly dispiriting if you want results that last longer than a week.
A calorie isn’t always a calorie. Eating 100 calories of high fructose corn syrup, for example, can have a different effect on your body than eating 100 calories of broccoli. The trick for sustained weight loss is to ditch the foods that are packed with calories but don’t make you feel full (like candy) and replace them with foods that fill you up without being loaded with calories (like vegetables).
The key to losing belly fat with exercise, though, is making sure your sweat session is intense. You’ll want to be working at 85% of your max heart rate at least, says Olson. “The higher your heart rate, the higher the release of epinephrine into the bloodstream and cells,” she explains. “A positive side effect of epinephrine is that it also activates greater release of abdominal fat into the bloodstream to be used for energy.”
Snacks are misunderstood in the weight-loss world – many people don’t realize that snacks can help you lose weight rather than gain it. If consumed in moderation as a way to relieve minor hunger pangs, snacks are a perfect bridge between meals and prevent you from consuming too many calories at your next meal. Choose snacks between 100 and 150 calories. Some or Dr. Smith’s favorites include shrimp cocktail, olives stuffed with blue cheese, an English muffin pizza, or a banana with dark chocolate. Try these shredder snack recipes. 
You can also lose inches in 30 days. "Just in my own 15 years of experience in working with patients, I have seen some lose up to five to 10 inches in a month from losing four to eight pounds," Jim told POPSUGAR. Keep in mind those five to 10 inches aren't just from your belly; those are full-body measurements from all major areas, including your waist, hips, chest, arms, legs, shoulders, and neck. He added that the inches lost depend on if you are weight training, what kind of cardio you're doing, how much water you're drinking, and how many calories you're eating.
One, it's impossible to "spot reduce." While you can target certain areas of your body in terms of building up the muscles in that area, you can't decide to just lose weight in your stomach, or your thighs, or your rear. It doesn't work that way. You can't remove subcutaneous body fat from specific areas of the body by doing exercises that target those areas. Doing hundreds of crunches will certainly strengthen your abs, but that won't reduce the amount of fat stored in your torso.
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.”
The scale is not necessarily your friend. You may want to lose fat – but the scale measures muscles, bone and internal organs as well. Gaining muscle is a good thing. Thus weight or BMI are imperfect ways to measure your progress. This is especially true if you’re just coming off a long period of semi-starvation (calorie counting), as your body may want to restore lost muscles etc. Starting weight training and gaining muscle can also hide your fat loss.
During this cleanse, you’ll still eat your four meals and three snacks, but you’ll make additions to help stimulate detox. Every morning for breakfast, have a cup of lemon water with flaxseed oil to help fight inflammation. You’ll also consume one cup of hibiscus tea and one cup of 100% cranberry juice daily. Full of antioxidants, these drinks will help your body fight off harmful free radicals. To aid in cleansing your liver, avoid alcohol this week.
If you have Celiac disease, of course you can and should eat gluten-free foods. But for those who choose gluten-free options because they think it’s healthier, think again. “As alternative grains are more bitter than their wheat-, barley-,  and rye- gluten-containing counterparts, the most common means to mask bitterness is…wait for it…by adding high levels of sugar,” says Alvin Berger, MS, PhD, nutritionist, lipid biochemist and co-founder of Life Sense Products. “The sugar is added in its plethora of alternative forms and names, to provide cover. The bottom line is that many gluten-free foods are higher in total sugars and high glycemic-carbs than their gluten-containing counterparts.”
Reducing alcohol intake can also help, says Fine. Alcohol contains about seven calories per gram—"just under fat, which equates to nine calories per gram.” And because alcohol is absorbed quickly, “when over-consumed, alcohol metabolism impairs metabolism of other macronutrients, such as carbs and fat, promoting…fat storage rather than breakdown,” she says.
Nontraditional pastas, like those made from beans, rice, and soy products, have become increasingly popular as a healthier option for pasta fans. However, that doesn’t mean you can load up on veggie noodles with no consequences. “We would be wise to remember that these pastas, while more nutrient dense than traditional white pasta, still have calories and carbohydrates,” says Monica Auslander Moreno, MS, RD, LD/N, nutrition consultant for RSP Nutrition. “Portions are still set at a measly 1/2 cup cooked; most of us do 2-3 cups of cooked pasta at a time. Try going ‘half and half’ with pasta alternatives and a vegetable pasta substitute.” Check out these weight-loss breakthroughs doctors wish you knew.
2. Ab Plank is a great exercise to really challenge your entire core and build up your strength and endurance. The Plank works the lower abdomens, the oblique muscles and your lower back. It takes focus and concentration plus some upper body strength. Start with holding the plank position for 30- 40 seconds and build your way up. You will be amazed at how strong your cores will get by doing this exercise regularly.
Incorporate at least two additional days of exercise -- cardio, yoga, or Pilates -- outside of the three workout days that you perform the 30-Day Shred program. According to the Centers for Disease Control, adults between the ages of 18 and 64 require 150 minutes of moderate intensity aerobic fitness every week and two to three days a week of strength training.

The 30-Day Shred workout was designed by celebrity fitness trainer Jillian Michaels. This weight loss DVD comprises three 20-minute circuit training workouts that are based on Jillian's 3-2-1 interval method. Each circuit alternates among three minutes of strength training, two minutes of cardio and one minute of core work to effectively burn fat and lose up to 20 pounds within 30 days. In order to lose weight with Jillian's 30-Day Shred series, you'll need to incorporate a sensible diet that allows you to consume the appropriate amount of calories and healthy foods in order to reduce body fat.
While it’s often assumed that bread is off-limits when you’re trying to lose belly fat, the right bread may actually expedite the process. Switching to sprouted bread can help out carb-lovers eager to get their fix without going up a belt size, thanks to the inulin content of sprouted grains. The results of a study published in Nutrition & Metabolism reveal that found that pre-diabetic study subjects whose diets were supplemented with inulin shaved off more belly fat and total weight than those whose meal plans didn’t pack this healthy prebiotic fiber.
