Diet drinks - the artificial sweeteners taste vile.
Having to forswear foods I have loved all my life.
Trying to find low carb meals when eating out.
As usual, covering a wide spread of territory ;-)
My exercise of choice is bike riding.
I am trying to work up to a regular 50k route which takes me about 2.5 hours.
One day my average speed will start to rise and the overall time come down!
My take on fat burning is that when you are breathing deeply but not gasping, you are in the fat burning (aerobic) zone.
When you are gasping you are in the full on carb burning (anaerobic) zone.
My ride seems to fit interval training nicely - the terrain is mainly flat, but every few miles there is a little valley with steep sides due to erosion by streams.
So flat with minor gradients, then a steep downhill followed by a steep uphill.
On the flat I cycle at a sustainable rate where I am breathing deeply but not gasping (although I plan to start pushing myself on a shorter ride to maintain higher intensity in the hope of increasing fitness and not just stamina).
Now the hills are fairly short, but they are pretty steep.
I have managed to stay out of the 'granny' (i.e. lowest rear gear and lowest front gear) but I have come close on hills near the end of the ride.
You have to push to keep moving, so at the top I tend to be gasping and my breathing then moderates on the flat.
I stop occasionally to hydrate - haven't mastered drinking and riding at the same time :-(
So, as far as I can see, fat burning in the main but some serious carb burnings on the up hills.
A pretty good all round training regime.
However I had a bit of a wobble at the end of my last 50k ride.
Off the bike, still breathing deeply to clear the oxygen debt I had built up, but O.K.
Tested my BG as quickly as possible - 4.9 which is in the 'normal' range.
[My fasting BG at the moment is running around 6-6.5]
I then suddenly felt all light headed and wobbly and had to sit down suddenly.
Now I am wondering if this was a false hypo - although I often finish a cycle ride with my BG below 5 with no adverse reaction.
I have even done a 30k ride in the morning fasted and not had any hypo symptoms.
As far as I can tell I was hydrated, had adequate glucose in my blood stream, but had exercised to the limits of my stamina (a bit left in the tank but it would have been a real push to do another 5-10k).
So why the wobble?
I thought the wobbles (or the wall/bonking) were due to people who were reliant on carbs for most of their energy running out of carbs and not being able to utilise mainly fats.
I seemed to have a few carbs left and I think I am reasonably adjusted to fat burning as I eat low carb and mainly protein and fat.
Before the ride I had eggs scrambled in butter and coffee with a little skimmed milk.
So puzzled, and also wondering what I should do to counter this.
Does this mean I should plan in some carbs before and during the ride?
Plan in some protein/fats during the ride?
Or just http://www.velominati.com/the-rules/ #5?
