Intermittent Fasting & Keto diet whilst jogging

Hey Guys

On most days I do Intermittent fasting (eating between 12-8pm) and am practically eating a Keto diet, but I’ve read it’s good to eat carbs whilst jogging to repair muscle and recover, I just wanted to know if any of you are eating the same way and what your experiences have been.

In my opinion the best diet for life is a broad one with a balance of different proteins, carbs, minerals and vitamins. This way you are providing your body with all the resources it needs to maintain itself.

My understanding is that it is protein that builds and repairs muscle, not carbs.

Are you eating a wide range of vegetables in this diet? If so it should be fine. Sometimes when we’re dieting or on specialised diets we end up eating from quite a narrow range of foods, because it’s hard to get it right. But we should be trying to eat from a wide range of foods - particularly veggies and whole grains. So just be mindful of that when choosing food. And for your gut & bowel health - carbs with high ‘insoluble’ fibre content (particularly oats/oat bran, and lots of veg) are good for you as the insoluble fibre is not digested, and gives you a good healthy scour on the way through! And as the fibre is not digested, the carb count is lower than it seems.

Are you doing the keto diet for weight loss, or health reasons like diabetes?

Yes it’s for health reasons and I believe my diet is quite balanced and I do eat a lot of veg. Thank you for your advice

Carbs after a run refuel the body, they are converted into glycogen and stored in the muscles... it’s protein that is the building block for repair or building of the muscle fiver. Your body will use other sources if it is lacking in carbs... and basically has two choices.

1/ use body fat to convert to blood sugars and then to glycogen

2/ use protein and break that down, turning it into glycogen.

So either way the fuel is going to be put there... and the keto diet is not incompatible with running for runs up to 60-90 minutes.

However, the choice of which source to use to fuel the muscles can be influenced by food intake. If the body goes into starvation/survival mode it would have a preference for storing fat (to give fuel after the lack of food) and so will use protein. That protein can be sourced by breaking muscle fibre down again... which would be counter productive to running.

As IannodaTruffe has said, the best diet for running is a healthy balanced one. I think either fasting or keto would be fine... but I would be concerned about the combination of the two.
