Healthy weight female: is eating once a day alright?

Answered on August 19, 2014
Created August 10, 2012 at 6:30 PM

Meaning, one big meal every 24 hours. Even though I'm at a healthy weight (5'6'', 120-125 pounds, 18 years old), I tend to over-obsess about what I eat to the point where it's the main focal point in my life. This then tends to lead to breakdowns in the form of massive, carb-filled, non-Paleo binges. Unhealthy, I know. However, I find that I don't have this problem when I eat one scheduled meal at a specific time every day. I think they only thing that makes me question my system is the term "fasting". I guess I always associate it with people trying to lose weight. I've also heard that fasting isn't ideal for women (true?).

Anyway, as long as I'm getting in enough calories/fat/protein/carbs and drinking plenty of water throughout the day, is this healthy?

Thanks everyone:)

nah kyle. It seems to be intrinsic to our physiology. Evidence shows that condensed eating windows (AKA IF) has positive physiological effects without even changing calories or foods consumed. All they did was monkey around with the timing of the meals and things like lipid profile, c-reactive protein, trigs, and insulin response all improve.

Not tough at all. I put 2500 calories in my one meal down pretty easy.

Or possibly we no longer need to maximize our running/fighting efficiency and can afford the luxury of diverting a percentage of our blood flow/resources to digestion at any arbitrary point in the day. I am sure that if Grok had found a windfall of bird eggs, apples, and squash he wouldn't sit there all day waiting for his bio-optimal feeding window (he'd eat when hungry assuming food was available--just like any other animal).

Fasting/Feeding windows are fine, but trying to scarf down a days worth of nutrients in a single sitting (I'm assuming you mean one meal ~1 hour of eating) is going to be tough. Especially if you already obsess over food. Plus there is some question about how much of those 2000-3000 calories you'll actually be able to absorb in a single sitting.

If you try it and you don't get all cranky, don't start dropping in weight, and are happy with it, then by all means rock on. But I expect that such a regime will be tough and will likely lead to larger binges (because you are going to get hungry).

If it was me, I'd try to figure out why I'm binging (are you not eating enough right now?) and fix that versus doing the same thing in a more concentrated window.

Try it out for a few weeks and see how your body reacts. If it is feeling under stress (i.e. if you get hungry throughout the fast) don't force it-- eat! A few people do 24 hour fasts, I don't know if it is good to sustain long term as it can increase cortisol sometimes, but if it is easier mentally than it would seem to be healthier. Mostly, just listen to your body. By focusing on eating whole foods, any bingeing tendencies will begin to disintegrate. How long have you been eating paleo?

Another concern I have in eating once a day is getting the appropriate amounts of calories/macronutrients. Most of us can't eat 2000 cals in one sitting, and if we can it leaves us ravenous shortly after.

You are going to have to do an N=1 and see what works for you. What works best for me is listening to my body. When I am hungry, I eat. When I am not, I don't force a meal and sometimes it becomes a 24 hour fast naturally. Listening to my body has instilled healthy eating habits, and I eat two meals a day.

Here is a really interesting essay about fasting, specifically how it affects women. And how the majority of tests with fasting have used men as the test subjects. I noticed in myself that the "increased energy, inability to sleep" aspect was true for myself:

http://www.paleoforwomen.com/shattering-the-myth-of-fasting-for-women-a-review-of-female-specific-responses-to-fasting-in-the-literature/

But I second (or is it third, now?) the wonderment of getting enough nutrients in one sitting, with one meal being the habit and norm.

It's fine. It's similar to LeanGains: http://examine.com/leangains-faq/

Yup no problem. Completely healthy. Studies show very positive changes physiologically with that sort of schedule.

I'm under the assumption that IF derived from the fact that hundreds and thousands of years ago, either humans spent all day gathering food of which they brought to the community by the end of the day to share with everyone and feast or soldiers would train or travel all day long and didn't eat until dusk. They saved their meal til the end because since digesting food is the single process that requires more energy than any other 'single' process in the body, they knew they would want to go to sleep after feasting so they saved it til when they wanted to go to sleep.

It's ironic how the more nutritional 'scientist' our species produces, the less synchronized we are with our bodies with respect to feeding it.

If you're only eating once a day in a 24 hour period, it's not a problem as long as you are getting your needed nutrients (I'd like to know how you can get that in one meal though). Leangains notes that women tend to do poorly and become very crabby if not fed adequately and should stick to a longer feeding windows than men (8 hour feeding window). I stick to a much less feeding window based on my work schedule though (4:30pm - 10:30pm), but I fit in three meals within that time period to make sure I'm getting all I need.
