Whether it’s a beer belly, spare tire, or love handles, there’s no doubt that some of us carry a few extra pounds that would look way better on a middle school arch nemesis (kidding… sort of). But running marathons, heavy lifting, or going the no carb route doesn’t guarantee a drop in jean size. The key to weight loss is (drum roll, please) burning more calories than devoured.
Fat Attack — The Need-to-Know
One pound of fat is roughly equivalent to 3,500 calories, so individuals need to burn 3,500 calories more than they consume to shed that first lb. But what’s the best way to do it? Researchers insist that diet is key— since studies show that losing weight comes down to a simple numbers game: calories in versus calories out Exercise improves fat metabolism in muscle but does not increase 24-h fat oxidation. Melanson, E.L., MacLean, P.S., Hill, J.O. Division of Endocrinology, Metabolism, and Diabetes, University of Colorado Denver, Denver, CO. Exercise and Sport Science Reviews, 2009 Apr;37(2):93-101. .
Still, exercising the right way will help tip the scale. In one study, overweight participants signed on for eight weeks of either aerobic workouts or strength training Effects of aerobic vs. resistance training on visceral and liver fat stores, liver enzymes, and insulin resistance by HOMA in overweight adults from STRRIDE AT/RT. Slentz, C.A., Bateman, L.A., Willis, L.H., et al. Div. of Cardiology, Dept. of Medicine, Duke Univ. Durham, NC. American Journal of Physiology Endocrinology and Metabolism, 2011 Nov;301(5):E1033-9. Epub 2011 Aug 16. . Surprisingly, the aerobic group burned 67 percent more calories than the resistance training group. Consider quick sprints over slow miles to slim that midsection, though; intervals are considered by many to be a more efficient way to burn fat Two weeks of high-intensity aerobic interval training increases the capacity for fat oxidation during exercise in women. Talanian, J.L, Galloway, S.D., Heigenhauser, G.J. et al. Department of Human Health and Nutritional Sciences, University of Guelph, Ontario, Canada. The European Journal of Applied Physiology, 2007 Apr;102(4):1439-47. Epub 2006 Dec 14. High-intensity intermittent exercise and fat loss. Boutcher, S.H. School of Medical Sciences, Faculty of Medicine, University of New South Wales, Sydney, Australia. Journal of Obesity, 2011;2011:868305. Epub 2010 Nov 24. .

Schmitz, K.H., Hannan, P.J., Stovitz, S.D., et al. Center for Clinical Epidemiology and Biostatistics, University of Pennsylvania School of Medicine, Philadelphia, PA. The American Journal of Clinical Nutrition, 2007 Sep;86(3):566-72. Effects of resistance exercise bouts of different intensities but equal work on EPOC. Thorton, M.K., Potteiger, J.A. School of Nursing, Georgia Southern University, Statesboro, GA. Medicine & Science in Sports & Exercise, 2002 Apr;34(4):715-22. .

Bye-Bye Beer Belly — Your Action Plan

And while calories count most when it comes to the number on the scale, researchers have found that higher protein diets have a greater thermic effect, a fancy phrase for speeding up metabolic rate Effect of dietary protein content on weight gain, energy expenditure, and body composition during overeating: a randomized controlled trial. Bray, G.A., Smith, S.R., de Jonge, L. et al. Pennington Biomedical Research Center, Baton Rouge, The Journal of the American Medical Association, 2012 Jan 4;307(1):47-55. The effects of high protein diets on thermogenesis, satiety and weight loss: a critical review. Halton, T.L., Hu F.B. Dept. of Nutrition, Harvard School of Public Health, Boston, MA. Journal of the American College of Nutrition, 2004 Oct;23(5):373-85. . (So maybe get that burger, but hold the bun?)
The body also adapts to exercise, so keep that workout routine varied to stay challenged while beating out boredom.

Bryner, R.W., Ullrich, I.H., Sauers, J. Department of Human Performance and Applied Exercise Science, West Virginia University, Morgantown, WV.
