A 2012 study also showed that people on a low-carb diet burned 300 more calories a day – while resting! According to one of the Harvard professors behind the study this advantage “would equal the number of calories typically burned in an hour of moderate-intensity physical activity”. Imagine that: an entire bonus hour of exercise every day, without actually exercising. A later, even larger and more carefully conducted study confirmed the effect, with different groups of people on low-carb diets burning an average of between 200 and almost 500 extra calories per day.
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.
If you eat your dinner restaurant style on your plate rather than family style, helping yourself from bowls and platters on the table, you’ll lose weight. Most of us tend to eat an average of 150 percent more calories in the evening than in the morning. You’ll avoid that now because when your plate is empty, you’re finished; there’s no reaching for seconds.
Be choosy about carbs. You can decide which ones you eat, and how much. Look for those that are low on the glycemic index (for instance, asparagus is lower on the glycemic index than a potato) or lower in carbs per serving than others. Whole grains are better choices than processed items, because processing removes key nutrients such as fiber, iron, and B vitamins. They may be added back, such as in “enriched” bread.
It is important to understand that weight is entirely a function of input and output. The input is the food you eat and the calories contained therein. The output is your energy output. To lose weight the output needs to be greater than the input. It is that simple. Do not believe any of the diet fads. If you are currently not gaining or losing weight then just burning 300 extra calories per week or eating/drinking 300 calories less per week (2 sodas for example or a small burger) WILL make you lose weight - in this case around 5 pounds of fat per year.
Whether or not you’re specifically aiming to cut carbs, most of us consume unhealthy amounts of sugar and refined carbohydrates such as white bread, pizza dough, pasta, pastries, white flour, white rice, and sweetened breakfast cereals. Replacing refined carbs with their whole-grain counterparts and eliminating candy and desserts is only part of the solution, though. Sugar is hidden in foods as diverse as canned soups and vegetables, pasta sauce, margarine, and many reduced fat foods. Since your body gets all it needs from sugar naturally occurring in food, all this added sugar amounts to nothing but a lot of empty calories and unhealthy spikes in your blood glucose.
Weight loss isn’t a linear event over time. When you cut calories, you may drop weight for the first few weeks, for example, and then something changes. You eat the same number of calories but you lose less weight or no weight at all. That’s because when you lose weight you’re losing water and lean tissue as well as fat, your metabolism slows, and your body changes in other ways. So, in order to continue dropping weight each week, you need to continue cutting calories.
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.
Yes, there is rest built in—two days, to be exact—but not until you’ve put in seven straight days of pedal-to-the-metal work. Rest on days 8 and 13 to allow your body to temporarily recover from the grind of the program. This will help you bank more energy for the work days that follow. These rest days are mandatory. For those of you hitting the panic button, don’t fret—12 out of 14 days at these intensities will still be plenty adequate for getting your shred. Remember: your body changes while it recovers, not while you train. So, consider these two days your chance to bust into the gym a little more ripped on days 9 and 14.
Trim Portions. If you did nothing else but reduce your portions by 10%-20%, you would lose weight. Most of the portions served both in restaurants and at home are bigger than you need. Pull out the measuring cups to get a handle on your usual portion sizes, and work on paring them down. Get instant portion control by using small bowls, plates, and cups, says Brian Wansink, PhD, author of Mindless Eating. You won't feel deprived because the food will look plentiful on dainty dishware.
That means taking in fewer calories than you burn. That means making healthier choices. That means ... well, you know what that means. You know what you should eat. We all do. White flours and white sugars are the enemy. Foods like white breads, cookies, white pasta, white rice, and white potatoes are out. (The same is true for "white fats" like butter and full-fat cheese.)
Another win for your morning cup of joe: Caffeinated coffee keeps things moving through the digestive tract. Since staying regular is key to a tighter-looking tummy, drinking about 8 to 16 ounces of java at the same time every day can help you stay on schedule. Remember: Sugary drinks can lead to weight gain, so skip fancy flavorings and synthetic sweeteners containing sugar alcohols, which can cause bloating.
Plus, a 2015 study from the Annals of Internal Medicine showed that for those who have a hard time following a strict diet, simplifying the weight loss approach by just increasing fiber intake can still lead to weight loss. Women should aim for at least 25 grams of fiber per day (based on a 2,000-calorie) diet, according to the most recent U.S. Dietary Guidelines. Not sure where to start? Check out our step-by-step guide to increasing your fiber intake.
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.
