Personal experience and Global Cycling News programming often disagree as they have speaking about Ketone diets.

As it turns out, a weight loss diet and their idea of a Ketone dirt are more or less the same thing. Protein and Fats and no carbohydrates.

Since my wife has been trying to lose weight (and has been successful) I've ended up eating GCN's sort of Ketone Diet.

It hasn't have any positive effect on my performance and I can tell you that. Yet when I stop on a ride and have a coffee and a sugar roll, I get not only a boost in performance but I feel a lot better after the ride without the need to fall asleep in the lounge chair before I can even put the bike away.

Now what this is telling me is that if you are on the Ketone Diet your (or perhaps only my) liver simply cannot metabolize fat fast enough to maintain a performance level, but the speed with which I can metabolize carbohydrates is enough to hold my performance levels (which, granted are only around 200 Watts on a good day) for my normal rides of around 40-60 miles with a lot of climbing.

Now if we are talking a scant 10K I have generated as much as 400 watts over that distance a couple of times this year.


Even in the Pro peloton the effect of ketons is questioned. Best and cheapest recovery drink is 0.5 liter of low fat choco drink: 2 third carbs and 1 third protein.

Again Tom 400 W is Pro level, even for 10 k miles. I set a new personal record yesterday for a Strava segment here in my neighborhood. Flat, no stop signs, almost no traffic and a moderate tailwind: 5.53 km in 7min 23 sec; average speed 45 km/hr. Average power of 259 Watt, measured with a power meter. Average heartbeat of 167 bpm. Overall place 44 out of 4070. First place out of 207 in this years classification in my age category: 55-64 yr. I am 62 y old. So I'm above average and nowhere near 400 W for a shorter distance. Again 400 Watt is Pro level.

That is faster than hell.

Four years ago with a good tailwind I did 5 miles (8 Km) a little faster than that average and I had to come to a complete stop every 1/2 mile and wait for a stop light to change. Then accelerate up to top speed again trying to get to the next light before it turned red so that I would catch the synchronization. I never made it and I came in a couple of minutes after the group I was with who were on the other side of the lights and never had to stop. Though when I pulled into the parking lot of the Century I was so far gone I couldn't find the car because there was a police car pulled in front of the driveway into that particular parking lot and I didn't even realize it.

I wondered around for five minutes before wandering back and the cop car being gone found the parking lot with the entire group waiting for me. And then having to hear about how slow I was.
