HIIT stands for high intensity interval training, and it’s a great way to build muscle without spending hours in the gym. The idea is to go all out for a short period of time, followed by a slower pace that allows you to recover. Think of jogging or sprinting all out for 30 seconds, followed by a minute or two of rest, then repeat. Short bursts of high-intensity exercises keep your heart rate up while adding lean muscle. More muscle mass equals calories burned on a daily basis. Also, the more lean muscle you have, the higher your metabolism is.
The one thing that is sure to make you lose weight is this simple equation: CICO, short for “Calories In, Calories Out.” In short, it means: a) if you eat more calories than your body spends, you’ll gain weight; b) if you eat less calories than you spend, you’ll lose weight. In spite of all their differences, all diet plans that aim to help you lose weight must adhere to this seemingly simple equation. However, most experts agree that, by itself, CICO is an incomplete and flawed approach due mainly to its focus on quantity over quality, and the fact that it doesn't take nutrients into account.
Going long periods of time without food does double-duty harm on our healthy eating efforts by both slowing down your metabolism, and priming you for another binge later in the day. (Think: You've skipped breakfast and lunch, so you're ready to takedown a whole turkey by dinner!) Make it your mission to eat three meals and two snacks every day, and don't wait longer than three to four hours without eating. Set a "snack alarm" on your phone if needed.
"Anytime you’re stressed, you probably go for food," Dr. Seltzer says. (Have we met?!) That’s because cortisol, the stress hormone, stokes your appetite for sugary, fatty foods. No wonder it’s associated with higher body weight, according to a 2007 Obesity study that quantified chronic stress exposure by looking at cortisol concentrations in more than 2,000 adults’ hair.
Contrary to other low-carb approaches, the South Beach Diet makes a clear distinction between “good” and “bad” fats (avocado oil is good, butter is bad), and only prohibits the consumption of certain, but not all, carbs. This means that, while the South Beach Diet has certain similarities with the keto approach, is not strictly ketogenic, but rather keto-friendly.
Okay, you get the point: belly fat = bad. How do you lose it? You have to think beyond crunches and planks and adopt a well-rounded approach. “It’s got to be more losing fat as a whole,” agrees Chris Gagliardi, a certified personal trainer at the American Council on Exercise (ACE). Without further ado, here are the best ways to lose belly fat once and for all.
Rather than rely entirely on the information provided by the companies to determine weight management effectiveness, we spent weeks browsing through hundreds of unpaid customer testimonies (not endorsed by any company) to get a feeling on the accuracy of the claims they make. In fact, these testimonials provided us with a much more truthful and in-depth insight regarding how effective diet plans really are. 
Consequently, researchers have widely discredited the hCG diet, which involves using hCG injections, pellets, sprays, or drops, and consuming  as few as 500 calories daily. The diet is problematic not only because there’s a lack of research on hCG supplements, but also because the calorie requirement is dangerously low, potentially leading to nutrient deficiencies, fatigue, hormone imbalances, blood clots, and other issues. Thus, most experts agree the hCG diet is not safe for anyone, the Mayo Clinic notes. (35)
"I tell all of my celebrity and professional-athlete clients to get between 6 and 8 hours of sleep per night. Everyone is overly focused on food, water and exercise, all of which are extremely imperative to weight loss and optimal health. However, without proper sleep, all of these the other factors are null and void. When you don't get enough sleep, levels of the hormone leptin drop, which increases appetite. This surge in appetite makes comfort food more appealing, which can derail weight loss efforts." — Jay Cardiello, celebrity fitness and nutrition expert

"People should pick activities they enjoy and that fit into their lifestyle in order to increase their chances of sticking with it to lose the last 10 pounds. For those who have hit a weight-loss plateau and can't seem to lose that weight, you'll need to mix things up in order to see results. Tabata-style training, HIIT classes and resistance training can all be effective weight-loss modalities for the right person." — Timothy Lyman, ACE certified personal trainer and Director of Training Programs at Fleet Feet Pittsburgh

Phase 1: This is the “metabolism reboot” phase, and the most restrictive part of the plan (but it only lasts two weeks, so that’s good news). You’ll basically cut all carbs from your diet, as this phase allows for no more than 40 grams of net carbs per day. The purpose of this first phase is to reset your metabolism and help your body burn fat instead of carbs. Carb lovers beware! You will not be able to eat bread, pasta, rice, and some fruit, which might be too restrictive for some. Because of this strict approach, you’ll most definitely see weight loss results at the end of the plan’s first seven days.
Why couldn’t we review for taste? Due to freshness and food safety concerns, the three meal-delivery companies that made our cut (South Beach Diet, Diet-to-Go, and Nutrisystem) only ship inside the continental US, meaning delivery is not available to Alaska, Hawaii, and other US territories. ConsumersAdvocate is headquartered in Dorado, Puerto Rico, which made it virtually impossible for our team to actually try the food prepared by the diet companies being reviewed. To make up for this obstacle, we read hundreds of customer and expert reviews regarding the taste of the food prepared by the companies that made our “best” list. We will continue trying to get the food delivered to our offices; if and when that happens, we will review the meals for taste and upgrade this article accordingly.

There’s a reason everyone harps on about protein: Not only does it help keep you full, but it’s also responsible for repairing the tiny tears caused by strength training in your muscles. This helps them grow bigger and stronger, nudging out body fat in the process. As a general rule of thumb, aim to get at least 70 grams of protein throughout the day, says Dr. Cheskin.


Don't get me wrong — exercising at any time is good for you. But evening activity may be particularly beneficial because many people's metabolism slows down toward the end of the day. Thirty minutes of aerobic activity before dinner increases your metabolic rate and may keep it elevated for another two or three hours, even after you've stopped moving. Plus, it'll help you relax post-meal so you won't be tempted by stress-induced grazing that can rack up calories.


"The American Heart Association recommends that men eat less than 36 grams of added sugar and that women consume less than 24 grams. However, for optimal weight loss, I tell my male clients to consume less than 20 grams of sugar per day and I tell the women to consume less than 15 grams. The easiest way to cut back on the sweet stuff is by consuming less sugary drinks and dressings. Cut the sugar, lose the fat, regain your health and life." — Dr. Sean M. Wells, DPT, PT, OCS, ATC/L, CSCS

"Eat vegetables before or with meals. Whether you are hungry on your way home or right when you walk in the door, snacking on veggies can help you keep your portions in check once you sit down to a meal. I also recommend starting your dinner with a vegetable salad or vegetable soup to fill you up and prevent overeating. — Ilyse Schapiro, MS, RD, CDN, author of Should I Scoop Out My Bagel?
"If a client has come to me looking to lose 10 pounds, I would tell them to simply move. Move more, and more often. Walk or bike ride to class or work, even park further away from your location in the parking lot. Take the stairs or take a walk during lunch. You don't have to spend hours every day in the gym sweating, but you do have to make a conscious effort to move more, and sit less. This works great because it doesn't feel like work and you're burning more and more calories throughout the day." — Ajia Cherry, personal trainer and Founder at Functional Innovative Training
"It's far more difficult to eat a healthier diet and fit in exercise if you don't plan ahead. Plan out your meals for the week ahead and go grocery shopping over the weekend to ensure you have the ingredients you need on hand. If you can, do some meal prep in your downtime—cut fresh veggies, marinate your protein, cook up a batch of whole grains in advance. When you're prepared you're far less likely to order takeout. — Jessica Fishman Levinson, MS, RDN, CDN, culinary-nutrition consultant and founder of Nutritioulicious
The number of calories you need to maintain or lose weight depends on a number of factors, including your age, sex, height, and level of physical activity, according to the FDA. To maintain a healthy body weight, the FDA recommends that you balance the number of calories you consume with the number of calories you burn through physical activity and your body’s metabolic processes. As a rule of thumb, the FDA recommends a standard 2,000 calorie diet for the average adult.

It can actually help you cut back on calories. That's because capsaicin, a compound found in jalapeño and cayenne peppers, may (slightly) increase your body's release of stress hormones such as adrenaline, which can speed up your ability to burn calories. What's more, eating hot peppers may help slow you down. You're less likely to wolfed down that plate of spicy spaghetti — and therefore stay more mindful of when you're full. Some great adds besides hot peppers: ginger and turmeric.
All meals are important, but breakfast is what helps you start your day on the right track. The best, heartiest breakfasts are ones that will fill you up, keep you satisfied, and stave off cravings later in the day. Aim to eat anywhere between 400 and 500 calories for your morning meal, and make sure you're including a source of lean protein plus filling fat (e.g., eggs, unsweetened Greek yogurt, nuts, or nut butters) and fiber (veggies, fruit, or 100% whole grains). Starting your day with a blood sugar-stabilizing blend of nutrients will help you slim down without sacrifice.
