It may seem counterintuitive, but eating more fat can help you shed bodyfat. Researchers found that when subjects boosted their fat intake to about 50 percent of their daily calorie intake while reducing carbs to around 30 percent, they burned more fat during workouts than when on their normal diets. Apparently, eating fat makes your muscles more efficient at extracting oxygen from your bloodstream. More oxygen facilitates better conversion of fat to energy, and your muscles turn into fat-burning turbines. So if you go lower carb, increase your intake of good fats, like those in nuts, fish and avocados,and you’ll get leaner faster. Incidentally, that finding may be why researchers in another study found that taking conjugated linoleic acid—a good fat—prior to workouts burns more fat and builds more muscle. Try about five grams.
