The guys from medical sciences stackexchange informed me that this post is not appropriate for their forum and suggested that I post it here. I hope for your mercy and forbearance - also as presently my question sounds a little bit too scientific, doesn't it? :-)

As it is mentioned in some sources (e. g. Alexandria D Blatt, Liane S Roe, and Barbara J Rolls: Hidden vegetables: an effective strategy to reduce energy intake and increase vegetable intake in adults or in the books of Barbara Rolls), one approach for weight loss is to concentrate on food that has a low calories to volume ratio. So it is basically kcal / cm³.

The idea behind that concept is that one chooses food with a high fiber or water content which makes the stomach filled (=> no feelings of hunger) but with less calories.

Unfortunately, in my research I can only find lists which state kcal / g (like e. g. at calories.info and others).

So my question is: in which book, scientific paper, or internet site can I find food listed by its kcal / cm³ value?

Wolfram alpha is happy to give you a number when you ask in natural language, "How many calories in X ml of ". It will also provide you with the density it used for the calculation, and with a full nutritional label for the exact amount you asked.

I haven't cross-referenced the densities it uses. But at least it gives you different numbers for "100 ml of hazelnuts" and "100 ml of chopped hazelnuts", so it passes that smoke test.

Of course, you have to be aware that this is even more approximate than calories by weight, just because for most foods, the density will be some kind of average. I haven't seen a source that gives anything like a 95% confidence intervals though, neither for calories per gram, nor for densities. The USDA raw data usually gives you a range for the cal/g for the samples they tested, but it is a very small number of samples per food.
