remind your lungs how much they like the taste of air.

Although I am taking care what I eat and given the increase in exercise I notice that my weight is sticking or even creaping up - is this normal or have I got some bizarre sort of reverse metabolism?
Thank you to both of you. I seem to remember last year the same happened and eventually it evened out. I am only about 8-9lbs from my target and did think the increase in exercise would boost weight loss, wishful thinking!!
As an ex WW I am keeping to fairly low calorie / low fat food and even not drinking so much so maybe eventually it will kick in. However, I am not increasing 'fuel' for my runs, maybe I need to look at that option obviously not the favoured chocolate bar......

I'm running somewhere tomorrow. It's going to be beautiful. I can't wait.

...One pound of stored fat is enough to propel most runners about 80 miles, provided that there are also enough carbs around to support the fat (or that the runner is running slow enough that the carbs are not the major energy source)...
Hi Trent: Can you explain the "provided that there are also enough carbs around to support the fat" part? You need some carbs (or glycogen?) present to burn fat? Btw, you always post really good stuff on nutrition. You should write a book or at least start a web site. Regards,
Thanks When running, you always burn carbs (i.e., glycogen) and fat. The effort you run correlates directly with the amount of carbs you burn: a high effort is equivalent to a high carb burn rate; a low effort is equivalent to a low carb burn rate (and a proportional increase in fat burning). The harder you run in terms of a percentage of your maximum effort, the higher proprotion of calories you use come from carbs. When running an all out sprint, nearly 100% of your energy comes from carbs or from anaerobic metabolism which replaces carb metabolism, and which requires carb metabolism to recover from. When jogging at a slow easy conversational effort, perhaps 60-70% of your energy comes from carbs, max. When walking, you are using stored fat as your primary energy source. When you run out of carbs, you bonk. Does that make sense?
Yes, I understand. Thanks! Besides ingesting carbs during a run, how can a runner move the bonk point? Does it automtaically move as a runner becomes better trained? That is, as a runner's body becomes better trained, it becomes more efficeint at burning carbs?
