Discussion Overview

The discussion revolves around the average weight of a filling meal, particularly in the context of evaluating the cost-effectiveness of a hot food buffet that sells food by weight. Participants explore various factors that contribute to meal satisfaction and fullness, including food composition and preparation methods.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Meta-discussion

Main Points Raised

  • One participant suggests that the average weight of a filling meal is around 1 lb, based on limited internet sources.
  • Another participant argues that fullness is influenced by factors beyond weight, such as the water, fiber, fat, and protein content of foods.
  • A theoretical calculation is presented estimating a daily food consumption of approximately 0.9 lb based on a 2,000 kcal/day diet, but notes that this is a lower limit due to undigested food weight.
  • Some participants emphasize that the actual weight of food consumed may be higher when considering water content in protein and carbohydrate sources.
  • Several participants express interest in methods to dehydrate food before weighing, indicating a desire to maximize the weight-to-cost ratio at buffets.
  • There is a discussion about the impact of cooking on food weight, with mentions of water content in meats and carbohydrates.
  • One participant shares a personal philosophy on dining out, suggesting to order only what one cannot or does not want to cook at home.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the average weight of a filling meal, and multiple competing views on factors influencing fullness and meal composition are present throughout the discussion.

Contextual Notes

Limitations include the reliance on personal estimates and theoretical calculations, as well as the lack of consensus on what constitutes a filling meal. The discussion also highlights the variability in food preparation and composition that affects weight and satiety.

TL;DR
What's the weight of an average full meal for a man?
Hi,
Just doing some informal research: what is the average weight of a full meal ( meaning it allows you to feel full after eating it) for a man /woman? Internet doesn't say much ; only found two posts both suggesting around 1lb . Anyone else know?
Edit: My goal is to decide whether the price of a hot food buffet (selling by weight) is worthwhile. If 1lb is enough on avg. then I compare to the price per lb. Of course I use some tricks like not getting anything with bones in it since I will not eat the bone.

Completely theoretical calculations:
Assume a 2,000 kcal/day diet with 30% of calories from fat.
Proteins and carbohydrates have ~ 4 kcal/g, fats have 9 kcal/g.
This gives a daily food consumption of ~67g of fats + 350g of protein/carbohydrate = 417g ~ 0.9 lb

Limitations: Not all of the weight of the food we consume is digested (e.g. healthy diets should contain 20-40g of dietary fiber), so the 0.9 lb of food per day is a lower limit.

Actually the weight of the food is higher because the water content has not been taken into account in the protein and carb sources.

Can you help me figure out how to dehydrate the food before it's weighed :) ( it's sold by weight).

If the only goal is frugality then certainly not.
Examples:
https://www.wegmans.com/products/prepared-foods/self-serve/entree/hot-food-bars.html
Whole foods $6-$8 depending on day
Tops $6.48/lb

Convenient but your wallet will be sad.

I don't know of any portable battery operated dehydrators.

Cooking removes some water from meat and especially fish. Meat is about 70% water and fish about 80%
Cooking carbs can add a good amount of water e.g. rice or pasta
Cooking veges can remove some water.

Our eating out philosophy is; Order only what you cannot or do not want to cook at home.

The only thing that comes to mind about foods drying out at buffets is waiting until the food has been sitting under the heat lamps a long time and is dried out, I usually try to avoid these, but sounds like that's what you want.

Any liquids on the plate, pour them back into the pan. Proteins are very filling and take a while to digest.

Generally speaking, carbohydrates tend to spend the least amount of time in the stomach, while protein stays in the stomach longer, and fats the longest.

So fried proteins would be good (chicken fried steak). Skip the salads, veggies, anything with a high water content, as these will pass out of your stomach quickly and leave you hungry very soon and will weigh a lot. Not a healthy diet, but you didn't ask what's healthy.

Shouldn't be too difficult to make (just need a heat source and time) but I doubt the buffet operators will approve.

So many choices then!
