Hi there. I was considering doing something similar to Intermittent Fasting, where I would exercise before I eat in the morning, and then eat about 30 minutes afterward until my normal dinner time. I eat around 4 meals a day with a base target of 1400 each day (sometimes I am slightly under / over by a few hundred), and already consume high protein and high fiber, hydrate well, and near my carbohydrate mark. I also focus on organic foods and whole foods.

I still plan to eat like I have been, just not eat before morning exercise and save my consumption until after I complete and through dinner.

For exercise, I do moderate high to high intensity training for just under an hour 5 to 6 days per week. Aerobic mainly, with some resistance throughout each workout.

My question is: Has anyone else done this and seen a significant (positive) change in body fat? Also, what pros and cons have you had fasting before exercise?? Thanks! :)

    So what you are saying is that choosing not to eat breakfast before exercising is harmful to the body? In what ways? I am looking for input so I can weigh my pros and cons.

    fasting is dangerous

    I'd like to see some research behind this?

    I don't fast so I can't offer a lot of advice but plenty of people fast (Ever watched "Fat, Sick, and Nearly Dead"? They all go on a juice fast for months). However, there are quite a few people here that swear by intermittent fasting. Which I believe is fast for certain times of the day or 1-2 days of the week. It can be very cleansing for your body to do a fast, detoxing.

    Hopefully, someone can offer you some decent advice on this and not some scare tactic with no information behind it.

    Sounds like you want to eat after you exercise in the morning and then another meal at dinner time? That's not really how IF works if you're going to eat breakfast and dinner. I'm not sure how analytical you want to get with this but it is actually better to wait at least an hour after you train to eat something in order to let your HGH proteins to do their thing. The Hodgetwins wait at least 2 hours after they eat. They also train fasted in addition to waiting 2 hours before eating something after a workout. Also, it is recommended that you eat 10grams of BCAAs to prevent muscle loss during a training session.

    i'll often train fasted in the morning, and then not eat until noon. then i have my eight hours where i'll eat all my calories, saving most of them for dinner. i like a big meal at night. and wine. then i'll fast for 16 hours. i couldn't imagine being awake through the majority of my fast.

    fasting is dangerous

    fasting CAN be dangerous....so can riding a bike, cutting up fruit, or giving birth.

    anything becomes dangerous when uninformed people get a hold of it

    just continue to research it and decide what's best for you

    IF has worked well for me, but I also eat healthy, workout, and net less calories than I consume.

    Try it and see if you like it. I tried it for a while and it wasn't for me. I was weaker and didn't have enough energy.

    For awhile, I would exercise before I ate breakfast in the morning. It worked for me. Then I decided I wanted to sleep more because getting enough sleep is also good for losing weight. Sometimes I'll do a little something before breakfast. Usually no more than 30 - 45 minutes though.

    I never eat before I workout. Never. If I do my stomach starts cramping up & hinders me. So even if I don't workout till 3pm or something I wont eat till after it.

    Nothing dangerous about it, just don't want to have the pain that comes along with it.




    But you are not really fasting at all, just delaying eating a little longer. You are still eating, but just not 1st thing in the morning. I can't understand how you would think it's fasting. Many people don't eat before a workout for the same reason I do.... if you are a runner like me then some of us have a hard time with food in the stomach & running...it does cause you to be near a toilet.

    This is not the first uneducated post I have seen from you.
    Do your research before posting for the sake of posting.
    There are plenty of intermittent fasters on here, in perfect health.

    I workout in the morning before i eat. If you would like to discuss it, ill be happy to. Please send me a message. I also do half day fasting. I refuse to discuss it here, because people like to call you down on something they are uneducated on.

    Im Heather, and we all fast every night when we sleep. Its just about what time we decide to fast. Kind of like day shift and night shift at work.. Is it wrong to eat after 7pm, when you wake up at 5pm because you work the night shift??

    Good luck to you & im here to talk if you are interested.. Ill be back online tomorrow. :flowerforyou:

    Don't listen to the people telling you that fasting is bad or "why would you do that?".

    There's actually an Intermittent Fasting group on MFP (http://www.myfitnesspal.com/groups/home/49-intermittent-fasting) where I've seen a few of these threads floating around, and more generally, I would suggest doing more research, e.g. http://www.marksdailyapple.com/monday-musings-thoughts-on-fasted-training/

    I do 20/4 IF and train ~19 hours fasted every day. I've lost fat and gained muscle. Anyone that says IF is dangerous has no idea what they're talking about.

    I will read through all of the replies in just a minute, but first I want to apologize for not being as clear.



    This is how my schedule looks now: Wake up / Breakfast / Lunch / Snack / Dinner / Exercise / Bed


    This is what I was considering doing: Wake up / Exercise / Breakfast / Lunch / Snack / Dinner / Bed


    Not changing my calorie/food intake at all. Just exercising as soon as I wake up before breakfast. Thanks for the links! I will read more into it. I was looking for input so I can see if it would be more productive for safe results. :)

    Thank you so much for the replies! I will check out all links and also the group here. I'm the type of person that researches before I attempt to change my dietary habits and activities. I think I may be okay with not eating first thing in the morning because the past few weeks it's taken me a little while to eat anyway, probably from all of the protein I have been consuming. I appreciate your input and help. :)

    Do you always post the most random and incorrect thing that comes to mind in every thread? That's the way it seems. Please stop spreading misinformation, it does not help anyone.

    If it works for you, do it. Lots of people do well training on a fast. I just know that if I, personally, try to exercise fasted I'm sluggish and beat down and I feel absolutely terrible - sick even. I can't work out on a full stomach either. A light meal 30-60 minutes in advance is best for me. I try not to complicate my life with too many fads and trends. I just do what feels best for my body. Good luck!

    Read this... the entire manuscript of "Eat, Stop, Eat" that walks you through the physiology of intermittent fasting and exercise. It is a VERY informative read and I think it will answer your questions.
