Why don't you eat meat? Sounds like too much activity, not enough fuel. If you want to lift twice a week and do the bicycle messenger thing. You need lots of protein, lots of rest, and lots of calories. The weight gain is likely just a... (more)

I believe the science shows that it does not make a difference when you eat your carbs (or fat, protein) but rather that you eat them or not. I once read a study that showed a week of low carb dieting though unregulated fat-oxidising enzymes,... (more)

Both fructose and galactose can refil muscle by being converted into glucose quite easily. Galactose by the Lelior pathway and fructose via the glycolysis/gluconeogenesis pathway. Here's an applicable blog post on the Perfect Health Diet Website:... (more)

If you were do do the triple murph everyday then yes I would think it'd be bad for weight loss. Not because of the volume, but because of the cortisol response. I love pushing myself beyond my limits, and as long as it is done occasionally then... (more)

Does lactose work well to replenish glycogen store after a workout? How does the body use this sugar?

borofergie 0 · November 29, 2012 at 2:45 PM

Unless you are lactose intolerent, it gets metabolised into glucose and galactose, both of which can replenish your glycogen stores.

Since excess protein will turn into glucose, will part of that go towards restoring muscle glycogen? I'm not 100% sure how this works, I'm coming from the perspective of a body builder. So any help/clarification is appreciated! Thanks :) (more)

Its a complicated procedure, first when the amino acid is broken down, it will replenish glucose in the brain before it replenishes any other muscle.

no as long as you are below 75% (give or take depending on level of fitness) of your max heart rate you'll be using fat primarily as fuel.

A muscle can be up till 4% glycogen, but that isn't normal in nature, only in carbloaded human athletes. My best guess will be 1-2%.
