Intermittent fasting, 12-18 hour fasting.


Quote  |  Reply

I noticed I did this after watching my weight and cal intake, I stopped eating after dinner usually after 6pm-7pm. I didn't know what it was and didn't mean to do it on purpose. I am done my calories for the day and late night eating usually ends up being bad food for me, so I don't. My meals are fairly close together and so I am never hungry really, except if I stay up late but it is reason for me to go to bed instead. 

Basically if you don't know what this is: it is not eating before bed and sleeping (and between the two you have not eaten for 12-18 hours approx). But the morning and rest of the day you eat normally and your healthy range of cals, may it be 3-6 meals, it doesn't matter.

I don't know if this has been helping me or not, some sources say it helps target suborn fat. And notice threads about eating late and if late night eating adds weight. Sumo wrestlers nap after eating/sleep after eating to allow more calories to be stored rather than burned but I assume they eat to gain or maintain, not lose and are a specialty type of athlete/life style (not an average joe).

Does anyone have more information or experience on this?

When you don't eat for that long, your metabolism slows down and you lose weight slower. It is better to eat something very light before sleeping....example would be fruit or yogurt....definitely not a meal though. Hope that helps!

If it works for you and you're eating enough calories per day, I don't think there's anything wrong with it. I have a feeling the fact that it's working has more to do with  not taking in a bunch of additional calories in the evening more so than the actual act of not eating for 12 hours.

Eating after a certain time doesn't prevent weight loss/encourage weight gain, whether you gain or lose weight just depends on how many calories you're taking in vs. how many calories your body is expending, regardless of when they're consumed.

But like I said, if this is something that you think is helping you lose weight than I don't see anything wrong with continuing to do it if you're consuming enough calories.

Not eating for 12-18 hrs is not going to make your metabolism slow down....it takes a couple days for that to happen. 

 

Check out leangains.com for some great information about IF. Personally I love it because I have become aware of what actual hunger feels like, and during the times I'm fasting I get so much done.

It is definitely not for everyone, but if you like it go for it. 

I agree w/ Kacieanne1015.  Short term fasting can boost your metabolism.  I've been doing leangains for a month, and I've lost 10 lbs since then.

I've heard that some people like leangains. I could never personally do it, and I think there are some people who should not attempt it -- generally, I would think that teenagers and anyone with a history of eating disorders would fall into that category. In my opinion, it could too easily slide into a binge-starve cycle.

I only have one meal a day, which is how I've always been, more or less. I don't do it as a plan or anything.

I'd gained 20 during a time I was eating out a lot, then going out to bars and having drinks often, but went low carb, lost that, and am still low carb.

Anyway, I usually have coffee in the morning, and then..dinner later. I probably eat every 24 hours, and have not noticed it slowing down weight loss, causing weight gain, or anything else.

I drink a lot of water, diet soda, etc during the day, and sometimes I'll have a low carb yogurt or sugar free pudding or something, but not usually.

I'm more likely to down a low carb protein shake at some point after dinner as I tend to be up late.

Long story short, no..that shouldn't slow down a thing, and anyway it doesn't matter what time you eat. Your body doesn't have a watch.

Oh that was the source I was referring too, good to know it is a reliable one :)

Thanks :)

If I get on another plateau or my weight loss really slows down I will be sure to try that. Fruit and yogurt is my fav snacks if I have it in the house too :)

I read that fasting is great for your body. But will drinking only vegetable juice during a fast hurt your body?

It is not going to hurt your body, but it defeats the purpose of fasting. The type of fasting we are talking about it just for a couple hours (12-18 hours), so you really don't want to consume anything with calories in that time period because you won't see all the benefits.

Be careful of fruit and yogurt they both have a lot of sugar in them( yes I realize fruit sugar is natural, but it is still sugar). I would recommend some kind of protein if you have to snack at night. It will keep you full, and I find I sleep better. 

Ah ok, I have heard that before now that I think of it, thanks :)

it's not really as simple as this- there is something with the regulation of hormones, insuline sensitivity for blood sugar levels and fat storage and leptin/ghrelin regulating hunger, and lots of others.  Some people have much better insulin sensitivity with eating fewer meals as their blood is not constantly bombarded with glucose (from carbohydrates).

This is total BS- minamum effects wouldn't even start to take place until after 36-48 hours.  Kacieanne1015 and Smashley23 have it right.

Personally, i've been experimenting with a 6 hour feeding window (4pm-10pm) in the evenings, kind of reverting to my teenage years when i wouldn't eat breakfast or lunch.  It's easy for me and i rarely get hungry, and it allows me to "binge" for dinner, eat lots of food and feel full.  It's been much better than the six meals a day eating every 2.5-3 hours thing i was doing a couple years ago, that TOTALLY made me OCD, stressed out, and i was ALWAYS hungry, especially after i just ate.   

Protein is a much better snack than fruit and yogurt... but it's relative- berries have relatively little sugars, as does plan yogurt- i love a bowl full of berries, plan yogurt and a scoop of protein powder before bed...
