Protein and calories

In Huel RTD how many calories in the protein?

I ask because of: Eating too much protein is bad for your arteries, and this amino acid is to blame | ScienceDaily

Organisations like the FDA specify that each gram of protein equates to 4 calories - although they no longer require that information to be on the labelling. Same with fats, calories from fat was removed from labelling requirements because their research showed the type of fat consumed is more important than the amount.

So for RTD, if you had the nutritionally complete daily intake of 2000 calories that would be 400 calories from protein – or 20%.

‘Protein contains four calories per gram, although a large part of the calories are lost as heat when metabolised by the body.’
