zaskar said:I did Atkins 4 years ago when i didn't know better. i was mtn biking at the time and did a 17 mile loop 5 times a week. 2 days on Atkins and i could hardly complete the ride. i got a bonk like i never felt before.

That's funny, i melted 40lbs of fat off my body eating plenty of good carbs. my body burns fat because i eat(every3-4hours) and ride 13-16 hours a week.just try the high fat high protien diet for yourself.

For those well established on Atkins it is claimed they have a higher endurance

I just wondered if there were established Atkins Dieters on this forum

ric_stern/RST said:In my professional capacity i would seriously advise anyone to NOT try Atkins, especially if they wanted to combine it with exercise. There is *no* physiological reason to expect you to perform well while on such a diet, and indeed many reasons to underperform while on such a diet.

Labarum said:Thanks for your contribution, Ric.
May I ask in what professional capacity you offer the advice?
As a 55 year old senior officer in the British Army I was directed by a Senior Medical Officer of the Royal Army Medical Corps: "Do Atkins," he said, "it works." He has offered the same advice to others I know - where they have done Atkins "by the book" it has been very effective.
One of the nursing staff expressed concern to me about long term high protein intake and stress on the kidneys. The SMO dismissed the nurses concerns.

- though it was not an issue at the start,
- and many find it falls dramtically.
The Atkins/low fat/carb controversy will continue. The medical and other professions are divided on the issue, but shouting louder (as many do) in defence of orthodoxy really does not contriute to a healthy debate.
I am not suggesting that you have done that, Ric, and I would like to see an intelligent and gracious exchange of informed opinion.
I am picking up that there may be an ultimate performance issue for those on a low carb diet. Some have said to me that while in ketosis you can plod along for hours at a moderate pace, but could run into difficulties when attempting to sprint too long or too often.
That's fine by me - at 55 I have no ambitions to be a boy racer.
On the other hand the Atkins handbook is very clear that ketosis can be maintained at much higher levels of carb input for those who are very active.
Snacking on fruit, dried fruit, or topping up with modest quantities of liquid carb is (I believe) a practice adopted by some low carb sportsmen.
I am truly trying to find a reasonable and practical way forward to enable me to lose that final 15 lbs, get fit and enjoy cycling the lovely lanes around where I live.
Any contribution to the debate would be welcome.
So, Ric, are you against the low carb philosophy in any circumstances, or are you simple saying those who live that way will be denied the best performance measured in both endurance and speed?
Upon what evidence do you base your claims, and with what professional authority?
