@jiffylush I know it has hugely improved my health, yes. For MY goals, both in my training, and general health.
I ride because: 1 – Super fun! 2 – Health Benefits, both short term and long term 3 – To get as fast as I can, and win races when I can. In that order.
I don’t support the idea of dumping absolutely anything into your body, no matter the health consequences, to go faster. I mean, if that’s the goal, we should all just take drugs, right? We’re supposed to be eating whatever can make us faster that is healthy.
Before going HFLC & IF, I used to be quite crashy, needed to smash a PB sandwich or something else 30 – 45 mins before any strong swim, ride, run, etc. Constantly crashing in the AMs, mid – late PM, etc, needing to drink sugar [ “fruit juice” ] to bounce back. Often light headed, spacey, fainty, weak, tired, sleepy, super ‘hangry’, etc.
I haven’t felt the sensation that people call “hungry” in about 2 years now. [That isn’t hunger = the actual need to eat food, made of protein and fat. That is the feeling of low blood sugar combined with having poor insulin sensitivity, so your body can’t moderate your blood sugar levels itself, so you need to ingest sugar to correct it.] I just know mentally that the tank is probably needing a top up. But I can fast for 24 – 36 hours without any symptoms at all, or sensations of “hungry”, low energy, etc.
In my riding, I’m relatively new to TR & structured, Nov 2022, but I’ve been riding hard, free-training including indoors over winter & Zwift racing [low level] for 6 – 8 years now. My longest was a 6 hr endurance – tempo ride with no fuel in 32 C = 90 F heat. Super high energy throughout, and after. Didn’t do it as any kind of test. Had lunch, went for a ride, had dinner. Via 2 – 3 AI FTP rounds and some testing of threshold WOs, I know my FTP for TR is really dialed in [def not too low], and I’m able to complete and advance my PLs in VO2 & anaerobics. I’ve increased my TR FTP 20% since Nov 2022 [Gotta love those beginner gains, right? Wish THAT could continue! LOL] and am now at 2.8 w/kg, which while not high overall, I think is pretty good for being strictly LV with inability to fit in any additional rides, don’t commute by bike, etc. Also, life has kept me from scoring anywhere near 100% on my plan adherence. And that does tons of damage to progress, of course. I think I will break 3 w/k soon if I stick to it, hopefully one day 3.5.
Have been HFLC & IF for about 18 – 24 mo now. So getting much stronger during this time, although that’s due to the increase in training. But it does mean my eating habits & lifestyle are not stopping me from getting stronger, and most notably, not stopping me from completing very high intensity WOs. I did d’Aujour, anaerobic 7.6, on Jun 16, and marked it just Hard. Boucher VO2 max 8.6 Jun 26, also just Hard. And I have done many Very Hard, and All Outs, and am not embarrassed or afraid to call them such, when they are. I’m not “pretending they were only Hard” to impress strangers on the internet, or make myself feel cool as I sit in a sweaty puddle on my bike!
[Although I really try to avoid putting myself in All Out holes!!!] So I’m far from “unable to do high intensity”.
Plus it’s just SUPER convenient. Lunch, come home, ride, dinner. Or lunch, ride all afternoon, dinner. No need to obsess about fueling, planning and bringing snacks, dosing every 30 - 90 mins, etc.
I’m not an alien! There are a ton of athletes, including some semi-pro / pro, who are using HFLC & IF. I always encourage people to give it a shot. Only takes about 1 – 4 weeks to start feeling the benefits, and see whether or not you dig it. I mean, if someone told me something might massively improve my quality of life and health, and it was pretty easy and fast to try, I’d at least give it a shot. That’s how I’m here!
I also eat treats pretty much whenever I damn well please. Few times a week I’ll have a dessert or treat, or some fries, etc.
Also worth note: My blood chemistry is perfect. Cholesterol, insulin, sugars, Na, K, etc. Last year’s physical & this year, just a few mo ago, 5/5 stars.
All positives, no downsides so far. IDK man, why not give it a shot? Then at least you could tell us HFLC - IF people you know for sure we’re fit for the loony bin!!
