The consensus is that exercising towards the end of your fast is beneficial for fat burning. Lots of people swear by it. I have tried it while fasting and had a couple of good workouts and a couple where I felt terrible. Try it, if you like it, go for it. If you feel terrible eat first. We experiment with ourselves and find the thing that supports our IF protocol. It's a journey that I'm excited to take.

"They also found that those who had exercised in a fasted state burned almost 20% more fat compared to those who had consumed breakfast before their workout. This means that performing exercise on an empty stomach provides the most desirable outcome for fat loss.

Javier Gonzalez, who is currently undertaking a PhD in Exercise and Metabolism, said: "In order to lose body fat we need to use more fat than we consume. Exercise increases the total amount of energy we expend and a greater proportion of this energy comes from existing fat if the exercise is performed after an overnight fast."

Basically, after you wake up your muscle and liver glycogen levels are depleted. I think I read somewhere that while sleeping your brain takes up to 30% of your glycogen stores. Fasted exercise burns off more of the glycogen and your body starts burning fat as fuel. That is why long distance runners, bicyclists, swimmers take in so many carbohydrates.

I say you should skip the preworkout, they are mostly hype. None of the guys at my gym that keep up on nutrition trends take preworkouts anymore. You can either drink coffee or take a caffeine pill instead. That's what most preworkout are, a bunch of caffee, yogimbi (sp) and other stimulants.

A lot of people take in a post workout meal of fast acting proteins right after they workout. It's the most effective time to shuttle nutrients and protein into your muscles.

Working out fasted is supposed to be amazing for you. I can do it on the weekends but during the week it doesn't work out very well with my schedule. I always feel pretty virtuous when I do it. HaHa.

Interesting dasher. More evidence that slowly professionals are learning about the benefits of HFLC. You are helping to get the information out to more people. I wish doctors would buy into it more often.

I exercise but I am not sure if my fast is even considered Intermittent fasting. I stop eating at 7:30 pm and then take a 56 calories pre-workout at 5:30 am and then breakfast at 10.30 am

I do two days of 5/3/1 program (strength) and 3 days of HIIT -started last week so can't comment on how much faster weight sheds.

I'm in a similar boat, but not necessarily due to exercising. I'm diabetic and I'll sip on an Atkins shake in the am if I start getting really hungry to avoid having my BG levels rise. It's not perfect, but once I lose more weight that problem should resolve and I can do more of a true IF.
