oh, me too, @BruceE!
Just before I started 5/2ing at the end of October, I went on my first bike tour - 320 km round Kangaroo Island in 6 days - well, it felt like a big achievement on many levels, I had been training for it for around 9 months, riding around 40 - 60 km around 3-4 times a week by september/october. I did drop a few kgs, maybe from 122 down to 120, but that was it! This despite my app telling me I had consumed around 3,000 calories for a 60 km ride! And I wasn't conscious of eating all that much more, but since my whole appetite has changed so much in the last 3 months since 5/2ing, I guess I now have a completely different internal metric for what "all that much" is! Still, I'm very proud of having done the bike tour, it was actually a huge effort, especially for someone of my mass at that point! After all, I was bordering on "morbidly obese" (goodness the medical profession needs to change their language - hello??? there's a person in there!!!) Sounding smug, aren't I? As of yesterday, I crossed a category from "obese 2" to "obese 1" - in case you hadn't heard my trumpeting of that fact from the other string! But the bottom line is, even that much moderate cardio really doesn't result in a weight loss for most people, and may even be harmful over time for the heart - I'm just about to look at "mark's daily apple" for what he writes about "chronic cardio" - I'll post a link if I can find one.
Before you ask, I'm still riding!! And getting PB times consistently, maybe that's weight loss, maybe it's HIIT? But maybe not quite as often, as I find if I do my HIIT one day, I really don't have the energy to also do a decent ride the same day, and I'm thinking I should be doing a bit more weight training, even though I do a reasonable amount in my pilates practice. So that will take a bit more time too! But I will never give up riding - I just love the freedom and the wind in my face!!
