Shy, you still need enough blood sugar to be able to burn fat, it's not a lot but if you don't supply it then the body will start to metabolize protein to make carbs, the process is called catabolysis and is pretty hard on the body.
Once you build this capacity it seems to stick around. I discovered a decade ago that I couldn't bike to Dr office for blood tests because i would register very high triglycerides. If I drove or took the bus my tri-g would be rock bottom (~50). This persists to this day, even though I am not training hard in 5 years now I still can't bike to a test if I want an accurate fasting result.
Early studies of training to utilize fat in exercise had negative results because the study durations were too short, it takes a minimum of 6 weeks to start the training effect.
Thanks Sadie
I'm vegetarian so I gets me carbs. Just don't munch on them when I'm running. I really don't like the sugar rush/crash scenario with carbs. My energy seems more stable running fasted, mainly for shorter training runs though.
If I'm hitting the 50k distances I'll take electrolytes and usually a healthy snack or two, but never the sports drinks, or anything crammed with sugar. I'd just barf that all up come mile20;D.
I certainly don't drop into ketosis, at least I don't think I do. I haven't set up a diet to promote that beyond avocados, olives, nuts, legumes and soy milk;) Yes I crave soy, and feel rubbish without it, even though I know it's just a placebo for real oestrogen. But needs must until the NHS backlog clears.
My main worry was with starting HRT, and how it might effect my running in the future. I can see now that it's going to be different, but no less rewarding or healthy judging by the responses to this thread. I'm actually excited to get started now, another box ticked. So thank you all ladies! A few years from now and It'll be questions on getting a sports bra to fit;D
Happy trails
