I don't know, but ever since I started eating paleo I don't feel the need to eat anything after dinner. Perhaps it's a sign that you are not eating enough earlier in the day if you are still hungry?
Not sure if you are on a losing or gaining path? If it helps, I'm gaining. I had trouble keeping weight on and maintaining a strong performance before and during CF, and discovered if I eat a nice snack before bed that it's helped me stay strong and keep the weight on. Cottage cheese, yogurt, nuts, berries, hard boiled egg, etc. Sleep is never affected, no weird dreams or anything. I also have a snack before CF 30 minutes prior to lifting those heavy weights. Too hot right now and I'm burning thru food too quickly.
On non-CF days I definitely have a snack before bed but only berries. It's just something nice :)
I wouldn't obsess over fruit, personally.
But here is a study that found eating all carbs later in the day to be cool: http://www.nature.com/oby/journal/vaop/ncurrent/full/oby201148a.html
I try to avoid carbs close to sleeping. Your body does not need a lot of carbs and at night especially...
You might pour some heavy cream over them (exchange some fruit for cream). That would help or eat cottage cheese instead.
Also going to bed earlier (if possible) should help avoid cravings and have other benifits.
I've been traveling this last week and meals have been difficult for me, so i've been enjoying apples with walnuts at night and I'm actually down a few pounds!
I generally don't eat at night but since I wasn't eating well during the day either, I had to eat something! I also did not notice any gastro issues either. So something new to think about next time you need to eat late or add fruit!
Normally I would think eating fruit at night would cause me to put on some weight, maybe this still could be true if eating well during the day.....in that case I'm assuming I wouldnt want the fruit.
So, go with what you're body is asking for!!
