Intermittent fasting or not eating for a few hours after a workout ... body signals?

Commented on September 04, 2012

For a short period of time I experimented with Intermittent Fasting (18 hour fasts with a 6 hour "eating window") but then stopped after reading about the detrimental effects that IF can have on teenagers (I was 17 a few weeks ago). I'd never felt low energy during a fast, but very rarely I started to feel very energetic, almost jittery. At some points I would feel light-headed, but still wouldn't be hungry. Also, after a hard workout (lifting heavy things) I don't always have an appetite so sometimes I don't eat straight away. A few hours after I have finished lifting, I'm still not hungry, but, again, I start to feel light-headed and lethargic.

Even though I'm not hungry, should I be eating if I start to feel this way? Has anyone else experienced this?

I doubt the stats would help, but I'm a 17 year old female, 172cm and 62kg.

I'll admit that was an exaggeration, reading was really seeing a few comments thrown around about stunting! Regardless, I did see this: http://www.marksdailyapple.com/dear-mark-matcha-tea-runners-high-stress-and-weight-gain-and-fasting-for-teens/#axzz25Um8dnfb and thought it was logical.

Yes, I am low carb but not really deliberately because it's the territory with Paleo. I have thought about salt, as I tend to have very tight muscles and don't add salt to any of my meals. Thank you for the suggestion!

Listen to your body and try out a few different things. See if eating straight after your workout makes you more energetic, or leave it till you feel hungry.

I went through a period of hating to eat until an hr after my workout because i'd just feel physically sick, so at the time i listened to my body and ate the right foods when MY body was ready.

Experiment to find out what suits you best and go from there.

Keep up the good work

I'm going to blame your diet; or the lack of variety that you're stuffing down your esophagus. I do everything better while in a fasted state; exercise, bang, study, read, exams, socialize, etc.

Studies have proven that it increases HGH, production of new brain cells, and improves total quality of life. Something else that you're doing is wrong. IF is one of the most beneficial health-related lifestyle behaviors that a human can engage in.

Fern,

If you are not hungry, then there's really no reason to eat. Don't consider it IF, consider it listening to your body. When I IF (and it does seem to help me) I will refuse food even if I am hungry. When I "naturally IF" I just don't eat if I am not hungry and eat if I am. I am currently injured, and cannot work out. Last week there was a day where I just didn't eat bearkfast, lunch, and then had a small dinner. I wasn't hungry so I didn't eat. I don't consider that IF

Are you eating low-carb? Try something salty, like bone-broth, if you feel light-headed and see if that helps.

For what it's worth, I never eat a special meal either before or after training, just my normal daily meals, and it doesn't cause any distress, but I'm pretty well fat/ketone adapted.

Here http://www.marksdailyapple.com/post-workout-fasting/#axzz205Wmp6ov I found that fasting after workout has certain benefits. Seems like it increases hGH (human growth hormone) production. I guess it is beneficial also for somebody who wants to shed some fat, as body has to replenish energy stores in muscles and has no other means for it except internal fat stores.
