This is a long post with my experience and thoughts on combining fasting and exercise.
I've had positive experiences with both a long juice fast and more recently with intermittent fasting. I think these are great tools but there are a few posts in this thread that try to diminish exercise and dismiss athletic guys who ask reasonable questions. So I'll make one point about how exercise can affect your internal health just as much (or more) than fasting. Everyone knows that heavy squats make your muscles stronger but many people don't know the other benefits of that exercise. Properly performed squats in a good training plan will increase flexibility, improve posture, increase bone density and strength, increase
testosterone levels and libido, improve nervous system function and brain health, and improve the function of your digestive system by strengthening the muscles associated with that system. Other exercises such as deadlifts, sprints, and presses also have most of those benefits.
I think fasting is a great tool but I think of it as more of a secondary tool while I think of exercise as more of a primary or essential tool for overall health.
The best methods for athletes and lifters to fast are debatable and there are experts with contradictory opinions. I'm not an expert but I will share what I've found so far.
Implementing changes to training or nutrition on an incremental basis are sometimes the best method and I think this applies to guys who are burning a lot of calories and want to try fasting so intermittent fasting seems to be the logical first step. I've read where others have recommended this and my recent experience confirms that this was a good method for me.
This article describes six ways to do intermittent fasting.
Leans Gains is a popular website which focuses mostly on the 16/8 style of intermittent fasting.
This post has a lot of information on how that can be setup.
Finally,
this article talks a lot about the challenges with intermittent fasting and possible pitfalls. It comes from another experienced trainer who has a different perspective.
Timing your workouts around your eating window will most likely depend on the individual and the type of workout. I do not believe that working out just before the eating window will be the best option for most guys who do high intensity training. It's possible and if you want to use that method then I suggest easing into one of the protocols from the Lean Gains website but my experience and research has led me to working out in the evening during the eating window.
Eric Berg's youtube channel has a lot of good information on the keto diet and intermittent fasting. I suggest
this video and
this video for learning to combine fasting and high intensity exercise especially when you are new to these concepts.
I suggest starting slow by doing something like 13/11 (13 hours fasting, 11 hours eating) and maybe transitioning once per week to a shorter eating window, i.e. 14/10 then 15/9 then 16/8 etc. Also I recommend for guys to plan ahead and find plenty of high calorie foods they can eat during the eating window because intermittent fasting can be a significant lifestyle change and getting enough calories during the eating window can be a challenge.
