soup[ for warmth

WildOscar

Why does soup make you so warm, a bowl of soup is much warmer than a cup of coffee on a very cold day. How come?

It's bigger, it's probably denser. So there's basically a lot more there to heat you up.

The caloric capacity of soup is greater than that of coffee.

:pac:

thanks guys it puzzled me why but I find it great

I saw a program about soup before, people staying fuller longer and found it easier to restrict calories. Apparently it sort of tricks your stomach into thinking it is full of food, i.e. you would not get the same effect eating the same veg whole and drinking a half pint of water. Found some studies on google scholar

Energy-yielding fluids generally have lower satiety value than solid foods. However, despite high water content, soups reportedly are satiating. The mechanisms contributing to this property have not been identified and were the focus of this study. A within-subject design, preload study was administered to 13 male and 18 female adults (23.7±0.9 years old) with a mean body mass index (BMI) of 23.0±0.7 kg/m2. At approximately weekly intervals, participants reported to the lab after an overnight fast and completed questionnaires on mood, appetite, psychological state, strength, and fine motor skills. After administration of motor tasks, participants consumed a 300-kcal preload in its entirety within 10 min. The test foods included isocaloric, solid, and liquefied versions of identical foods high in protein, fat, or carbohydrate. Single beverage and no-load responses were also tested. The same questionnaires and motor skills tests were completed at 15-min intervals for 1 h and at 30-min intervals for an additional 3 h after loading. Diet records were kept for the balance of the day. The soups led to reductions of hunger and increases of fullness that were comparable to the solid foods. The beverage had the weakest satiety effect. Daily energy intake tended to be lower on days of soup ingestion compared to the solid foods or no-load days and was highest with beverage consumption. Thus, these data support the high satiety value of soups. It is proposed that cognitive factors are likely responsible.

We compared the influence of three solid/liquid preloads to a no-preload condition given at lunchtime on hunger ratings and energy intake of the lunch and subsequent dinner in 12 lean and 10 overweight young men. The preloads (vegetables and water, strained vegetable soup, chunky soup) were of the same composition and volume but differed in distribution of nutrients between the liquid and the solid phases, and in the size of solid particles. Hunger ratings were reduced by the preloads; there was a significantly greater suppression of hunger after the chunky soup than after the vegetables and water. In both groups, the soups reduced energy intake at lunch, although the chunky soup had the most effect. In the overweight subjects, a reduced lunch intake was also followed by a reduced dinner intake. The benefit to weight control of large particles in soup should be evaluated.

When I was dieting a year or so ago I was eating tins of soup at lunch and was surprisingly full considering the minimal amount of calories they have compared to what I might usually eat in one sitting.

In the TV program I think they said the soup spent more time in the stomach, while liquids pass though you, so the veg & water combo might lead to the water just passing though and a small amount of veg remains to be digested, so you feel less full and tend to eat more.
