For some people (even those who sit before a keyboard all day) tracking what they eat and how much they exercise actually helps.

Yes, eating less and exercising more is ‘easy’, both to do and to understand – but since when have the majority of human beings behaved logically? How else to explain why, in the richest economy in the world, all those ‘logical’ people are becoming increasingly obese?

Surely, a better approach would be to increase the effort involved in using a keyboard, so that creating a weight-loss spreadsheet would double as a reasonable workout?

Just a thought.
