How long does a meat and fat meal stay in the stomach?

If I eat meat/fish with fat (with or without greens) for dinner, how long will it take untill my stomach is empty again?

I haven't found nothing but information about mixed meals with starches, which might take about 4 to 5 hours to leave the stomach.


From my personal experience my stomach stops "blubbering" and feeling full about 1 or 2 hours after dinner.

I ask this question because I should take my Thyroxin on an empty stomach and I've read that it is best converted into fT3 in the night.

Normal digestion of food generally takes between 24 and 72 hours. After eating, for passing food through your stomach and small intestine it takes about six to eight hours. Then food enters large intestine for further digestion and water absorption.

Not all food empties or moves through the system at the same rate. In other words, the meat, fat, vegetables, and starch travel at differing rates. Other influences on motility, is the size of the meal/bolus, and how distended the stomach becomes. Increased distention, stimulates motility. The texture or consistency of the food is important. Solid, ground, pureed, and liquid foods, move at differing rates. People who chew their foods longer, have greater motility and absorption changing emptying time.

I think you're okay to wait 2-3 hours, but 4-5 is safe. So, if you have dinner at 6 and go to bed at 10pm, take your med at bedtime and you'll be good to go. At my hospital (I'm a RN), all levothyroxine (Synthroid) is given at 10pm. My understanding is that the protocol changed because several peer-reviewed studies found better results, perhaps do to the reasons you suggested.

Make it a bedtime ritual.

Chemically, yes. Heat turns solid fat to liquid form once it spreads its liquid phase temperature. The reason meat turns dry and chewable once oil dissolve (unless it gets cooked long enough the meat or protein chain spoiled into stew). People parched meat in high heat or breaded essence in deep fry in moderately short time to protect both the juice and marble fat from extreme dissolving and vaporisation.

Proteins and fats take between 5-6 hours to digest, when eaten alone. Carbs take under an hour, and fruit, about 20-30 minutes. This is why food combining is important to those looking to lose weight. If you eat carbs with proteins and fats, (e.g. Hamburger), the carbs sit and wait for the meat to finish digesting before they can begin. In the meantime, all the fat you consumed in the protein portion, now stores due to the carbs on hold. Carbs store fat. That is their function. A proper food combing diet would instruct you to eat your friuts first, carbs 2nd, and end the day with Proteins and fats. You can't store fat without carbs, so all the meat and fish you eat by itself, will never gain an ounce, unless you mess up and have carbs within 5-6 hours of them.
