Too little sleep or too much sleep can throw your stress and regulatory hormones out of whack, and may lead to weight gain. A single night of sleep deprivation can increase levels of ghrelin (a hormone that promotes hunger), making you more likely to overeat the next day. Reduced sleep may also lead to fatigue during the day (duh) and less physical activity, which may be another reason why people who regularly don't get enough sleep tend to gain weight.

Sorry keto -- the Mediterranean diet is king. Endurance athletes and celebrities like LeBron James and the Kardashians have raved about the high-fat, low-carb ketogenic diet -- which was among Google’s most-searched terms this year. But Dr. Louis Aronne, an endocrinologist at NewYork-Presbyterian and Weill Cornell Medicine who runs the Comprehensive Weight Control Center, noted that the Mediterranean diet “is the only diet that has been proven in trials to promote weight loss and reduce the risk of heart attack, stroke and other cardiovascular diseases.” This meal plan includes using olive oil rich in healthy omega-3 fatty acids as your main cooking oil, and loading your plate with fruits and vegetables, whole grains and lean protein like fish and chicken, with the occasional piece of red meat. The American Heart Association recommends a similar diet that emphasizes whole, unprocessed foods, particularly fruits, veggies and whole grains, as well as low-fat dairy products, nuts and legumes, and non-tropical vegetable oils, while reducing salt, sugar and trans fats.
Why does HIIT training work better than conventional cardio for fat loss? When you do cardio at the same pace, your body adjusts itself to the workload and tries to conserve calories. (After all, your body doesn't know how long or hard you plan to work out.) Interval training forces your body to burn more calories -- and tap into fat stores -- because it has no choice. Science says so: One study at Laval University found people who performed HIIT cardio lost nine times more fat than people who performed moderate cardio at a consistent speed.
For even more impressive effects on body composition: aim for exercise forms which elicit a positive hormonal response. This means lifting really heavy things (strength training), or interval training. Such exercise increases levels of the sex hormone testosterone (primarily in men) as well as growth hormone. Not only do greater levels of these hormones increase your muscle mass, but they also decrease your visceral fat (belly fat) in the long term.
If you’ve got weight to lose and you want it gone fast, try swapping out your usual proteins in favor of fish. Not only is fish lower in calories than an equivalent amount of beef or chicken, a study published in Obesity reveals study subjects who added omega-3 fatty acids, like those found in fish, to their diets shed more weight and had an easier time keeping it off than those who skipped them.
“As your body’s perception of stress increases, cortisol, often called the stress hormone, is released from the adrenal glands,” explains Nana Yaw Adu-Sarkodie, MD, a board-certified family physician practicing home-based care in Baltimore. “Normal levels are released when you wake up in the morning or during exercise. Chronic stress can lead to increased cortisol and other stress hormones, leading to increases in sugar in the bloodstream, weight gain, digestive issues, depression, and a host of other health effects.”
What can I eat on a no-carb diet? Many people reduce carbohydrate intake to help them lose weight. Carbohydrates are important macronutrients, but cutting them can help people to lose weight by making it possible to reduce calories and improve feelings of fullness. Alternatives to carbs can make it easier to stick to a low-carb diet. Learn more here. Read now
Blood vessels (veh-suls): The system of flexible tubes—arteries, capillaries and veins—that carries blood through the body. Oxygen and nutrients are delivered by arteries to tiny, thin-walled capillaries that feed them to cells and pick up waste material, including carbon dioxide. Capillaries pass the waste to veins, which take the blood back to the heart and lungs, where carbon dioxide is let out through your breath as you exhale.
The trick here is not only to avoid all obvious sources of carbohydrate (sweets, bread, spaghetti, rice, potatoes), but also to be careful with your protein intake. If you eat large amounts of meat, eggs and the like, the excess protein will be converted into glucose in your body. Large amounts of protein can also raise your insulin levels somewhat. This compromises optimal ketosis.
A 2014 Harvard study found that men who did twenty minutes of daily weight training had less of an increase in age-related abdominal fat compared with men who spent the same amount of time doing aerobic activities, and other studies have shown similar levels of success when guys hit the gym to cut down on fat. The implication: Guys can cut belly fat most efficiently with weight training.
Ten months ago I bought the 30 day shred and thought I would give it ago. I started off 3 days a week on level one and really enjoyed it! I normally hate working out but it was so quick and fun I didn’t mind, I then stepped up to level 2 and was doing it 6 days a week. I noticed I started to see results quickly and after switching to a healthy diet and running combined with the dvd. I’m now 84lbs down ten months later and still loving the workout. It’s so quick to do I get up every morning and do it before school run and work etc.
