To encourage ketone production, the amount of insulin in your bloodstream must be low. The lower your insulin, the higher your ketone production. And when you have a well-controlled, sufficiently large amount of ketones in your blood, it’s basically proof that your insulin is very low – and therefore, that you’re enjoying the maximum effect of your low-carbohydrate diet. That’s what’s called optimal ketosis.
You can’t skimp on sleep. Losing weight for good calls for a total lifestyle change -- and that includes getting more Zs. Missing the recommended seven to nine hours of shut-eye has been linked repeatedly with increased obesity rates. “When you don’t sleep enough, it certainly affects your brain,” explained Dr. Arad. “What we’ve learned is that people who don’t sleep well are making poor choices — eating more unhealthy diets, and they are obviously more fatigued, so they become less physically active.” In fact, people who sleep six hours or fewer per night on average consume about 300 extra calories the following day.
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.
So she started researching. She found something called the 21-Day Meal Plan, which seemed like it would work with their lives. The plan showed them what foods they could eat and what they should skip. They started by cutting sugar, junk and processed foods and added vegetables, fruit, legumes, whole grains and lean meats, such as chicken and turkey. In the first week, Parent noticed a difference.
"With all the different tips out there, it can be tricky to understand exactly which exercises work the best. HIIT is great for fat burning and will get your heart rate up, but I’d also recommend including strength (resistance) exercises too. Try lifting weights, using resistance bands or using the weight machines at the gym as these will increase your metabolism to help with weight loss, and increase your muscle strength. It’s important to mix-up your whole-body workouts so you don’t get bored."
If you’re only getting a minimal amount of sleep each night, that leaves more time for you to snack and make otherwise unhealthy decisions that could affect your weight loss. Although it will vary from person to person on how much sleep you actually need to be most effective (and therefore make progress toward your weight loss goals), the ideal number is typically 7 or 8 hours, says Dr. Cheskin. (Struggling to get that shut-eye? This doctor-approved breathing exercise will help you fall asleep fast.)
Don’t buy your tickets to Bonnaroo just yet; the kind of acid that will help you slim down is the stuff right inside your cabinet. A 12-week study published in Bioscience, Biotechnology, and Biochemistry reveals that obese study subjects who made vinegar part of their diet dropped more belly fat than a control group, and other research suggests that acidic foods, like vinegar, can increase the human carbohydrate metabolism by as much as 40 percent.
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.
Remember that it takes a 3500-calorie deficit to lose one pound of fat. That is, you have to either burn off 3500 calories through exercise or eat 3500 calories less than you burn in a week. Break this up into daily limits. To burn 3500 calories a week, you should aim to have a 500 calorie deficit every day. For example, you can exercise to burn 250 calories and cut 250 calories from your diet.
"One of the hardest parts of losing weight is maintaining the lifestyle changes you’ve made. It’s difficult to stay motivated all the time, especially if you’ve slipped up along the way. But don’t let this affect your end goal. If you’re feeling particularly unmotivated, ask a friend to join you for your workout and then afterwards cook something healthy for dinner together."
You might not find the motivation to burn away all that fat if you don't have the muscles to show off underneath. A well-rounded, symmetrical weightlifting program will build your muscles and make them something to be admired. Choose a split workout, or an all-body workout, and work out three to four times a week. Work all major muscle groups, and leave 48 hours between working the same muscles to prevent overtraining. Another benefit of weight training is the boost it gives your metabolism.
3. Tabata: Tabata is another form of interval training and involves 8 rounds of 20 seconds exercise followed by 10 seconds rest. Sounds easy enough but exercise should be done at a high intensity. This exercise can be done using rowing machines, dumbbells or thrusters. This is a tough exercise and is best for those who have very less time in their hands.
Frequent and sustained cardio training is one of the best ways to burn fat and boost metabolism. One of the best cardio exercises to perform is running, according to the American College of Sports Medicine, as it burns a high number of calories per hour and improves cardiovascular health. ACSM recommends training five days a week, with a minimum of 60 minutes per session.
Worried about hunger? There are a lot of simple tactics you can use to curb your appetite. Drink caffeine in the morning to kill your appetite until lunch, eat a lot of vegetables and protein, drink a lot of water, and make sure to have your sugar water at night. The first few days can be tough, but the hunger goes away a lot faster than you’d think.
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."
Potassium, magnesium, and calcium can help to serve as a counter-balance for sodium. Foods that are rich in potassium include leafy greens, most "orange" foods (oranges, sweet potatoes, carrots, melon), bananas, tomatoes, and cruciferous veggies — especially cauliflower. Low-fat dairy, plus nuts, and seeds can also help give you a bloat-busting boost. They've also been linked to a whole host of additional health benefits, such as lowering blood pressure, controlling blood sugar, and reducing risk of chronic disease overall.
For example, a 200-pound guy following this program would consume 200 grams of protein per day, and eat 2,000–2,200 calories—that’s approximately 420 calories (about 50 grams) from fat, and 880 calories (220 grams) from carbs. Your protein and fat intake will stay relatively constant, but your carbs can be raised or lowered as needed (see Step 5). So, if you’re taking your shirt off on Saturday, begin following this protocol the Saturday prior.
No, we’re not telling you that you need a tummy tuck (although that would flatten your belly, we suppose). Rather, there are several common health conditions that can make your belly bulge and until you fix the anatomical issues underneath, nothing else can flatten it out. For instance, many women have a diastisis recti, or separation of the abdominal muscles, after pregnancy. In about 25 percent of these women, the muscles never quite come back together, leading to a permanent protrusion. Similarly, a hernia (congenital or from an injury) can also cause your belly to stick out. Both conditions can be resolved surgically.
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.”
Make sure to program your cardio exercise in with your weight training the right way, though — a 2017 study found that performing cardio and weight training workouts on alternate days was far more effective for burning belly fat than stacking the workouts on top of each other in the same session. Put the two together, and watch that unhealthy midsection shrink.
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.
