There are those that claim HIIT is less effective than low intensity longer duration cardio. Their reasoning is that most of the calories burned during HIIT come from stored muscle glycogen (carbs) rather than coming from stored adipose tissue. This is true but this is not a bad thing. Research has absolutely proven that it does not make any difference whether stored carbohydrates or stored fats are used as the fuel source. The only thing that matters is how many total calories are burned and more total calories are expended through HIIT as opposed to low intensity low duration cardio.
The least intrusive weight loss methods, and those most often recommended, are adjustments to eating patterns and increased physical activity, generally in the form of exercise. The World Health Organization recommended that people combine a reduction of processed foods high in saturated fats, sugar and salt and caloric content of the diet with an increase in physical activity.
1. Boost your metabolism throughout the day: Your BMR regulates how many calories you burn at rest and the more you move, the higher your BMR, and the more you’ll burn when standing still. Small efforts like taking the stairs, walking to pick up lunch, even playing pool with the guys during happy hour can all jumpstart your metabolism.

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
Over the past five or six days of this protocol, you’ve been in deep ketosis and burning only fat, but you haven’t had to be particularly calorie restricted. In order to reset leptin levels and prevent a large drop in energy levels, you need to re-feed. Contrary to our normal recommendations, you need to pound down the carbs. When it comes to normalizing leptin levels, fat has no effect, while carbs are going to send them sky high.
Do this: Eat 6-8 small meals per day, spaced 2-3 hours apart. Don't go longer than three hours without eating—your body will go into starvation mode, which can cause you to store body fat and make it more likely that you'll overeat at your next meal. Speaking of overeating, just because you're consuming more meals doesn't mean you should take in more total calories. Determine your ideal daily caloric intake for fat-burning (see Rule 1) and divide that more or less evenly between your 6-8 meals.
Unintentional weight loss can occur because of an inadequately nutritious diet relative to a person's energy needs (generally called malnutrition). Disease processes, changes in metabolism, hormonal changes, medications or other treatments, disease- or treatment-related dietary changes, or reduced appetite associated with a disease or treatment can also cause unintentional weight loss. Poor nutrient utilization can lead to weight loss, and can be caused by fistulae in the gastrointestinal tract, diarrhea, drug-nutrient interaction, enzyme depletion and muscle atrophy.
Weight loss occurs when the body is expending more energy in work and metabolism than it is absorbing from food or other nutrients. It will then use stored reserves from fat or muscle, gradually leading to weight loss. For athletes seeking to improve performance or to meet required weight classification for participation in a sport, it is not uncommon to seek additional weight loss even if they are already at their ideal body weight. Others may be driven to lose weight to achieve an appearance they consider more attractive. However, being underweight is associated with health risks such as difficulty fighting off infection, osteoporosis, decreased muscle strength, trouble regulating body temperature and even increased risk of death.
Always be sure to get enough protein and healthy fats to start your day. Your energy after a breakfast of 2/3 eggs, 1/3 – 1/2 an avocado and 1 piece of fruit or Breakfast Tacos will be significantly higher and sustain you longer than a carb-heavy bowl of cereal. Think about it this way – if you want to lessen the “carb-chase-cravings” and energy drops that often hit in the later mid-morning and/or late afternoon, the key is to increase your protein and healthy fats earlier in the day. Avocados and blueberries are great breakfast additions because they are nutrient rich superfoods that can easily be added to your daily diet.
If you want to shrink your gut, get enough protein in your diet. In this case, about 25 percent of calories. Why? For starters, protein makes you feel full and helps you build muscle (which increases metabolism, thereby making it easier to lose weight). Just as important, high-protein diets have been shown to be the best way of attacking belly fat. In one study, published in the International Journal of Obesity, Danish researchers put 65 people on either a 12 percent protein diet or a 25 percent protein diet. The low-protein dieters lost an average of 11 pounds, which isn't bad. But the high-protein subjects lost an average of 20 pounds--including twice as much abdominal fat as the low-protein group.
"Feeling stressed can wreak havoc on our bodies. It can cause our body to produce the steroid hormone cortisol, which can make you crave sugary foods that provide instant energy and pleasure. Short-term bursts of cortisol are necessary to help us cope with immediate danger, but our body will also release this hormone if we’re feeling stressed or anxious. When our cortisol levels are high for a long amount of time, it can increase the amount of fat you hold in your belly."
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.
At its core, burning fat comes down to the process of lipolysis—the breaking down of fat lipids, explains Seedman. This happens in the mitochondria of the muscles, or the powerhouses of the cells, responsible for generating the energy our cells need to do their jobs. Exercise has been shown to improve mitochondria function, which then promotes fat breakdown, Seedman adds. Plus, working out helps regulate pretty much all the hormones that optimize fat loss.
