I did quite some experimenting with this.

Fruit moves fastest and green leaves. Meat, cheese, oil and fats slowest.

But we often eat combinations: and the slowest component of your food determines the speed of the whole.

Also: it's a one lane road and "over taking" is not possible.

So, eating a fast moving meal after a slow moving meal results in the fast mover getting stuck behind the slow mover.

Hence I start my day without and slow food (only fruit, herbs, green leaves, spices, ginger => usually a smoothy); and end the day with slow food (oily food, nuts, seeds, beans; usually combined with green leaves as we need a lot green leaves).

YMMV

There have been alternative (often mad) health proponents who have insisted upon only eating fruit in the morning for years - similar(ish) reasons. I think there is probably something to it.

Isn't slow food going through your body during sleep something that'll impact your sleep quality?

When you wake up you are basically fasting so your body is ready to take a hit. Slow food will go through your body faster when you eat it in the first half of your day.

Interesting.

A great opportunity to add "YMMV"

> Also: it's a one lane road and "over taking" is not possible.

I've eaten some hamburgers at Krystal's that definitely overtook whatever else was in front. Some folks have had the same or similar effect from White Castle, although I never have. Chipotle on occasion moves things along rather briskly too. No fruit or green leaves in any of them.

It may be that it's not a digestion thing, but some other factor they have that accelerates the process.

I don't disagree with your findings, but here's the model I use:

- Fiber: ^

- Dairy: v

- Coffee: ^^

- NSAIDs: vv

- Ice cream splurges: vvv

Eating bitter greens can cause the body to secrete more bile and that speeds up fat digestion.

Best poop-related comment I've seen.

n=1

But interesting nonetheless, thanks for sharing your findings.

Have you found that coffee speed things up?

For me i drink close to a gallon of water a day and that truly cleans me out daily.

Just to be clear I thought the typical advice has been fiber -> protein -> carbs, for blood sugar reasons, you're saying to frontload fiber/carbs & backload proteins for easier digestion? That is interesting, I wonder what studies there are on this.

yeah my mileage is i eat fruit and i get cramps and the squirts for the next two days.

as I've gotten older my ability to consume fruit, onions, garlic and most dairy (and coffee :-( ) has been taken away from me. its really a miserable experience for someone that enjoys eating new and interesting things all the time.

What do you mean, the human stomach is absolutely not a "one line road", your comments lacks the basic biological understanding. What you're describing is a good generic diet and maybe that's why it feels good but please learn a bit more about the stuff you are expetimenting on.

I will add an anecdote that from observation, two people on the same diet over long periods can have significantly different poop frequencies, and differing regularity.

YMMV. It's not just determined by the food intakes, there are individual factors.

At a guess, these individual factors start with 1) genetic component to reactions to substances such as lactose and to caffeine. 2) Gut microbiome.

In other words, saying "change diet and you can change the poop schedule" is true, but "with this diet you will definitely get this schedule" is not.

Or just don't eat meat and cheese at all
