Does it matter if you eat warm or cold food on your fast day?

-I am thinking something like this:

Warm food warm up your body, so less calories from that food is used for warming your body. So if I only eat cold food, should I not the be “allowed” to eat a bit more calories on a fast day than if I only eat warm food?

Potlatch,

If your aim is to lose weight I’m not sure why you would be trying to ‘cheat’ more calories.

Have you any thoughts on how many extra calories you think you ought to be allowed eating cold vs hot food?

I am not doing 5-2 to loose weight. I am doing it to lower IGF-1 in my blood.

I am just interested in the science how 5-2 works. If more calories from your food is used to warm up the body, can you then eat a little more food without affecting the IGF-1 levels?

Have you read the book?
It states clearly that lowering IGF-1 levels is achieved by the fasting period and not by what or how much or even what temperature of food.

Might I suggest that you read the book, or read it again if you have already done so, and then take a look on line at the connection between IGF-1 levels and fasting, as it may be that you can achieve the results you are after by decreasing your eating window eg only eating betweent 1pm and 7pm, and not reducing how much you eat.

Hi Potlatch,

I expect Amazon is referring to the 5:2 fast diet books! If you go to the home page of this website you will see a link to 5:2 diet books…

I can tell you that cold, cooked potatoes have a lower GI than when they are hot due to structural changes to the starches, but (AFAIK) the calories remain the same.

The question is not as silly as some people might think. Naturally it is true that warm food contains more energy than cold food. In a sense heating up 200 grams of food from 10 C to 60 C “infuses” it with about 10 kcal extra. That is not much though, and I would bet that in total the difference in effective energy absorbed by the body is significantly smaller than even that.
