I was deep in thought the other day, whilst on a train from the south to the north of England, as to the importance (or lack thereof) of calories as a measure of food intake, and other alternative ways of monitoring our diets. Naturally, due to a, quite usual for me, ridiculous train of thought, I ended up researching the different calorie intakes needed by some of the extremes of the natural world and was fascinated by the results. Here are my favourites:
A humpback whale needs 100,000 calories a day. This means they need to consume a ton of crill a day. Just to survive!
A household cat needs 270 calories a day. Which works out as one small tin of cat food. So, no need to break the bank there.
A mouse only needs a minuscule 10 calories a day. That’s the equivalent of 3 Peanuts.
So daily, we eat 50 times less calories than a whale and 200 times more than a mouse.
