How long are your rides? For rides around an hour to an hour and a half I can ride while fasting, even at the end of an 18 hour fast. The trick is to just work up to it.

Up to 50k there’s no problems. But, above 50k I’m gonna end up emptying my glycogen storage.

Apparently fasted training can help teach your body to stretch the glycogen stores. You won't set any PR's doing so, but it could help you down the road.

Anecdote: I tried intermittent fasting for 11 months with very, very little to show for it. I did the 18 hours off and 6 hours of eating plan. I have also tried a strict vegetarian diet for 6 months with no real changes in blood work. My Cholesterol didn't move to the dismay of my PCP and myself quite frankly. Biology: I am a professional Firefighter that ran 1000 miles and bicycled 250 miles during this time frame.…

Have you also tried going a whole day without eating, say 8pm as your last meal and then no eating until 2 days later at 8am, basically 36 hours. Doing that once a week or so is pretty effective. There's a whole host of benefits to longer fasts as well. Helps so much with appetite control, resets your hormones, plus autophagy, etc.

Totally this. Of course Anecdata etc etc. I lost almost 40 lbs this year with 5-2 and exercise 3-4 times a week and have been able to maintain my goal weight doing 6-1. I don't eat anything crazy when I am eating. Just less carbs and more protein. I am also vegetarian.

in my experience, sleep is the first problem to be solved. If a person can't get good quality and quantity of sleep nothing else helps. First sleep then meditation to tame the chronic stress response. nothing else - fasting, diet, exercise etc helps before sleep. btw alcohol and caffeine screws the quality of sleep.

Exercise and meditation can help with sleep, so I guess those two should come first?

The hype around intermittent fasting is nothing more than the novice effect & the diminishing returns kick in pretty fast.

As someone who still practises IF, I have been wondering if many of the immediate benefits (weight loss, low cholesterol, reduced inflammation markers, etc) are mostly apparent in sedentary, obese people. IF might work brilliantly for them because it's a psychologically "easy" shortcut to fixing a terrible diet.

For those of us who are already lean + good diet + high activity levels, I'm not convinced that IF really brings much to the table. I'm still doing 16:8, but only because I was eating breakfast in the morning out of habit, rather than hunger.

When I lose weight, I actually switch back to a regular (5/day) meal plan and reincorporate breakfast. That's the best way I've found to lose fat while maintaining muscle and energy levels. My biggest problem with losing weight on IF is that I have a tendency to binge during the eating window. Eating something small every 3 hours is the easiest way I've found to keep this urge in check.

How do you maintain energy levels through a 36 hour fast? Edit: Thanks all! This’ll help me progress from 16/8 to consistent longer fasts.

I am relatively adapted to it at this point, so it doesn't bother me as much. I time it so I start the fast towards the evening and then it ends mid-morning - so you're only really pushing through one full day without food. I'll have coffee/tea for caffeine and electrolytes seem to help depending on your situation. Start with several smaller fasts before going full 36 and if you need to eat before the full 36 hours a…

Do you break fast eating specific things or just go about eating your usual meal?

Not sure why this has been downvoted. This is absolutely correct and verified by dozens of studies.

Can you please link a few? I’m compiling material.

Vegetarian diet still allows for milk and cheeses which can be very high in fat and cholesterol.

How do you know it wasn’t just the exercise and fewer calories?

I have done a couple 36 hour fasts. What broke me was hunger, not low energy. Didn't feel any less energized than usual, really. But resisting the urge to eat after you've been hungry all day and someone puts a meal in front of you is hard.

in many people’s experience (mine included) there’s phase change sometime in the 48-72 hour mark in which hunger/appetite essentially disappears (some describe it is gone, some as easily ignored background noise)

Personally, I’ve gone more than 14 days several times, I usually start when not feeling very well (and lacking appetite) which makes even the first couple of days trivial.

If you do want to go farther than 36 (at your own risk of course - I am not a medical professional and this is not medical advice) make sure you are well vitamined, well hydrated, and well electrolyted (e.g. with snake juice) - very often, need for some essential vitamin/mineral masquerades as hunger or appetite.
