    great question. I have been wondering about and struggling with the same issue. Unfortunately I cannot find any printed information about it. I want to bulk up some but don't want to gain it around the waist at the same time. I hope some of you guys out there can help us out.

    From my experience it's pretty hard to do both at the same time and get good results. I would recommend doing one then the other. Because getting discouraged is a big part of it when you don't see the results you were hoping for.

    Well I know that when I use to work at a gym. They would tell me that Cardio was one great way to lose body fat, also high impact aerobics was great. I think I heard them say aerobics was the best cause you lose body fat but at the same time you are gain muscle. Might want to check into that. I on the other hand have started to do a lot of cardio and will drink ICE cold water here and there and have noticed that I have started to lose a large amount of weight with in the last 3 wks. I have lost 8 lbs.

    SJLatJock, is the ice water part of the weight loss regimen or just to hydrate?

    The usually accepted doctrine is that you can't do both at the same time. Whether it's true or not, I'll leave to you to decide.

    Ice cold water helps because it keeps you hydrated *and* it cools your core. The cold makes your body make heat to warm it back up. Heat is energy. So cold water is making your body burn more calories, thus making you lose weight.

    I've heard that ice water thing, and have to wonder if it's just psychological. Now my curiosity is piqued.

    Let's see. A Calorie (capital C, aka a kilocalorie) is the energy unit for food. It's also the amount of energy it takes to heat one thousand cubic centimeters of water 1 degree Centigrade.

    Let's say you drink water that is very nearly frozen, at 0 degrees Centigrade. The relevant question is "How much energy do you burn over normal water?"

    Let's say room temperature (and thus room temperature water) is 70F, or 21C. Then you're heating that water an extra 21C versus drinking normal water.

    A 16oz water bottle is ~470 cubic centimeters in volume, so let's say you drink 3 of those per workout.

    Then you are heating ~1500cc of water an extra 21C. That's 31500 calories (little 'c'), which is 31.5 Calories (kilocals.)

    I guess it comes down to how efficient the body's methods of generating heat are, because if it's 100% efficient that's basically no calories at all. But it's unlikely that the body is 100% efficient at converting its energy stores to heat. Let's say it's 33% efficient -- that would be about 100 extra Calories per workout you'd be burning. I have no idea if 33% is the right number, though.

    And that's if you're drinking 3 full 16oz water bottles that are, literally, ice cold.

    That's also above the amount you burn for normal room temperature water, which is another 24 Calories, base.

    In sum, if your body were 100% efficient at generating heat from energy stores, drinking three 16oz water bottles full of ice-cold water (32F, 0C) would burn 55 Calories.

    If anyone has any idea of the body's actual efficiency (or probably efficiencies, I'm sure it differs depending on where it's getting the energy) at generating that heat, I'm curious now.

    I always assumed this was just a myth, but if the body's not super-efficient at making heat, that could actually consume some relatively serious calories.

    Really the only way to lose fat and gain muscle at the sametime is working out with weights
    weights really are the only way to gain muscle mass...and pound for pound muscle burns the most cals than any other tissue in the body
    so as you gain muscle fat is being burned at the sametime
    cardio also works in this regard but we all know it doesn't add muscle
    that's why long distance runners look so emaciated
    But there are ways to up the anti with your workouts...decreasing the downtime between sets and working the larger muscle grps more will get you where you wanna be faster
    I think that ice water thing is a lot of hokum
    The body is extremely efficient at conserving calories in that way and has counteractive measures to stop energy loss in cold

    Something that works for me is to use weights early in my work out. This way my body uses up any extra glycogen in my body. Then I do an hour of low impact cardio. This is very minimal effort on an elliptical machine. I've gained about 10lbs of muscle and have shredded a great deal of fat.
