HIIT was originally developed by track coaches to train runners, but it has crossed over to the fitness industry due to its fat-burning benefits confirmed many times over in scientific studies (see "HIIT Findings"). A lot of these studies found that subjects performing HIIT burned significantly more body fat—and in less time—than those who did steady-state cardio programs.
Try on clothes and pay attention to the fit. A great way to identify weight loss is if your clothes become too big or fit loosely. Stay positive, even when the numbers on the scales increase. When building muscle, you may experience weight gain -- lean muscle tissue -- but as long as your body fat percentage is decreasing, you’re on the right track.

Getting more fiber into your diet, especially soluble fiber found in oats, chia seeds, legumes, vegetables, and fruits, can help reduce fat accumulation in the abdominal area. Psyllium husk is another great source of fiber—and has zero calories. Fiber swells up with water, increasing the bulk of your stomach contents and giving you a feeling of fullness. It also reduces fat absorption from food by binding with bile acids required for the digestion of dietary fats. Fiber can also bind with sugars and other carbohydrates, delaying or reducing their absorption into the bloodstream.
Tempting as that post-workout shower may be, making time to hold a static stretch at the end of your workout can increase your muscle mass by as much as 13 per cent, according to US research. How? It has much the same effect on your muscles as resistance training, a study published in the Journal of Applied Physiology found. Both cause micro tears that prompt the manufacture of muscle fibres. Stretch yourself swole.
Dr. Smith applies this same idea to diet. He maintains that if you eat the same foods all the time, your body adjusts to that specific diet. Your metabolism stabilizes and fat accumulates as a result. By varying the types and quantities of food you eat, you’ll prevent your metabolism from slowing down and trick your body into burning more calories. In this way, diet confusion keeps your metabolism off-kilter and fuels your fat-burning engines.
The first step might be symbolic. If you bring your least-favorite diet book to the Lakeshore Athletic Club Lincoln Park, 1320 W. Fullerton Ave., at 2 p.m. Sunday, Stevens will shred it in exchange for a copy of "The Overfed Head." The destroyed books will be recycled and could possibly end up as toilet paper, a fitting end from Stevens' perspective.
"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."
