=============================
Yes. I enjoy walking a lot more now that I've added more carbs to my diet.

Yes and yes. Read enclosed link. Its how it all works. There is no
magic, voodoo or incantations in the management and practice of a
well-planned ketogenic diet, just science.

Hard exercise will also do the same. It is more difficult to train with
heavy weights due to lowered stamina. A solution that I'm using is to
follow Lyle McDonald's Targeted Ketogenic Diet (TKD) as detailed in his
Ketogenic Diet book.
I train heavy 4 days a week and am doing LC, so it's certainly possible. 😉
For a while, though, I would concentrate on getting through induction and
figure out your CCL (from Atkin's) before you'd ever have to worry about
this sort of thing. Start exercising easy as you being your LC lifestyle.
Good luck,
Mark

The glycogen goes, but I have never had as much energy as living in ketosis
has given me. My muscles are not weak.

The transition into or out of ketosis can produce a brief period of fatigue.

That's probably because of how out-of-shape and over 'carbed' you were.

Only in the beginning...but it can be a serious butt-kicker the first few
times....

Besides sugar, muscles can use fat for fuel. A consistent training
program on a low carb diet can train the muscles to use fat in a more
efficient way.

That's true. Once a person has become adapted to LC, their body will
generally not use up stored glycogen as does the body of a person who is not
adapted. Hence, they can usually perform various types of activities on LC
better than someone who doesn't use fat as efficiently. However, there are
still limitations that can be encountered under certain situations.

Have their been studies on this? What time period are we talking for
adaptation? Does this mean that any sugars taken prior to or after a
workout are not being burned effectively and/or providing uptake into the
muscles? Wouldn't this mean that insulin is also being affected?

My understanding is that it depends on the person. Some adapt quickly,
other don't. Some adapt moreso than others.

Not from what I've read, at least not to a significant degree. The real
feat is getting the body to become more efficient at using fat for fuel,
rather than sugar. After all, one has to be broken down through a a more
complex process than the other.

Well, living mainly off fat for energy and then bringing in carbs for
specific activity is all about controling and using insulin.

There apparently is a troll here.
I did not write the header on this thread.
