Been reading about fasting and Keto a lot the past week and was trying to work out how long you can fast before your metabolism slows down. Came across this quote on a Keto article which says a calorie deficit of over 3 weeks causes metabolism to slow.
Here’s the thing: any diet that involves restricting your calories can result in a slower metabolism. If you maintain a calorie deficit for 3+ weeks, you’ll have to worry about your metabolism slowing down regardless of whether you’re eating low-carb or not.
Anyone know how true that is. I’m thinking it can’t be so clear cut. Surely a fast with extreme calorific deficit would slow your metabolism faster than a -500 deficit would, for example.
Into my 3rd week of IF 16/8 and done a 24 hour fast during it too. In the middle of a 2 or maybe even 3 day fast right now to see how it affects my recovery and power. Finding it all very interesting and actually kinda fun, but I don’t want to screw up and slow my metabolism, even if just short term.

If you find it interesting and actually kinda fun then continue! You won’t screw up or slow your metabolism just by eating less.
You may lose some weight, which will lower your caloric output but that’s the goal, right?
Oh yeah, totally okay with the weight loss. That’s definitely a big part of how I fell into this a couple weeks ago. But also wanted to see how I could hack it and if what people are saying about it is true.
Just don’t want to dig myself into a hole, though I’ve cutting back on the TSS. Tempo or SS rides only during the week and one big threshold effort on Saturday to test power. I don’t have a way of actually testing metabolism so in my simpleton way of thinking I’ll just blast up a 40 minute climb as hard as I can every Saturday and I’ll know from power and HR if something has changed drastically for the worse.
My volume is usually a lot bigger so should be pretty fresh every weekend. Wish I had another way of working this stuff out. Resting HR should drop when fasting, but don’t think that on its own would signify some metabolic issue… Maybe feeling cold when you’d normally feel okay?
