I found this one out the hard way. When I started doing P90X I did not exactly follow the diet program, because I figured I could eat normally and lose weight because I was doing all the exercise. Needless to say I did not exactly lose a lot of fat (did lose some) on the program, although I did gain plenty of muscle.

Nice to see someone spreading the correct information.

Yes, I have known this for quite a while 🙂

In reply to David Brown. Those are, however, under stress. When talking about 50 kcal being burned by 1 lb of muscle, these people implied it's the RMR that benefits.

I’ve given this matter of calorie expenditure a lot of study and thought over the years. Realistically, it is very difficult to calculate fat calorie expenditure based on total caloric intake because of variables such as cellular makeup, nutrient intake, physiological make up, level of physical training, and gut microbiota. (Google – David Brown unabsorbed calories)

Of course, muscle is always burning fat calories. Excerpts:

“During light to moderate aerobic exercise, such as jogging, stored fat provides 50 to 60 percent of the fuel.” (Nancy Clark’s Sports Nutrition Guidebook-4th Edition – Page 111)

Studies of his muscles indicate that he’s burning about 80 percent fat and 20 percent glucose. Frank Shorter is running aerobically while running a mile in five minutes. (Smart Exercise: Burning Fat, Getting Fit – Page 43)

The highest rate of fat burning achieved by the cyclists in Carey’s study was 0.7 grams per minute. In fact, my natural fat burning rate was on par with the highest fat oxidation rate cited by Tim Noakes in “Lore of Running.” During the days of eating a high-fat diet, I reached a fat-burning rate of 1.2 grams per minute at Ironman pace, confirming the theory that a high-fat diet shifts your body’s reliance on fat for fuel, but my rate shifted back down to 0.8 grams per minute after two days of carbo loading. It seemed the protocol had no effect on me. (http://triathlon.competitor.com/2012/06/nutrition/inside-triathlon-magazine-fat-burning-machine_31034)

So much misinformation out there! What goes in your mouth is so important!
