Wow! it doesn't feel that long ago.
In my search for high energy low bulk foodstuffs, I soon became aware that carbs (including sugars) and proteins both have 4 calories per gramme and fat has 9 calories per gramme - and no matter what I do, I can't increase that. As ever, water and fibre add to the bulk. It seems that those three-course meal pills I heard so much about as a kid belong at the implausible end of science fiction
