    It's about both. If you are very overweight/obese --- then just focus on good clean eating. If you are focused on losing the last 10 lbs -- focus on calories and carbs.

    I'm just wondering how you came up with this number is all. Searching online you find numbers all over the place, but 1% of muscle mass seems to be common (not saying that's right and you're wrong, just trying to learn). And is your 7-8x lean body mass figure taking into account bones/skin/etc? 1% muscle mass for the average person would be way under 1000g, more like 200-300 tops.

    I've already answered your question and provided plenty of reading material for you.

    Appreciate the info StackingPlates. Though I was asking Choco where he got his numbers.

    And not saying those sources are bad sources, but after reading over them, you've got one study that's 13 years old which had two subjects, and another study that's 24 years old which had three subjects. I'd love to see more recent, larger studies. Especially on something that's so easy to see numbers all over the board. A ten minute Google search found numbers anywhere from 200g total (including the liver) on up to 10-15g per pound of lean body weight.

    You're right, there are a lot of different answers out there for the googling.

    This is from the PB page 154.

    The average person can only store about 400 grams of glycogen in liver and muscle tissue (even a highly trained
    athlete can only store perhaps 600 grams).

    And that agrees with the vast majority of the searches. The other thing to consider is no matter how crazy the exercise, it's not like you're 100% depleting all of that glycogen either.

    I feel like we are all getting a little off topic here, i mean if i am switching from a lower calorie diet, even if it is vegetable centric to mostly protein and fat, even if it is more calories can i lose weight because it is more "fat burning" as some people claim??

    I don't seem to have a final answer on all of this. thanks!

    How about if you post a sample menu so we can see exactly what foods you're planning to eat? What will be your protein sources, carb & fat amounts~ that sort of thing. Easier to give guidence if we have more info.

    So~ my 5 pound water regain is about average? How about that.
