food and drink, health and fitness

If you are a heavy coffee drinker as I was, just give up coffee like I did seven weeks ago (I used to spend about two pounds a day on it) and you've got one hundred unspent pounds there looking at you.

But then if you count all the diet coke and coke zero I used to drink too (half a litre a day on average), and the occasional frappuccino (at least once a week) it turns out that in seven weeks I have saved 140 pounds. Twenty pounds a week. A grand a year. Practically a very decent holiday somewhere.

And that's not taking into account the fact that I feel much better, I sleep better and therefore have more energy, and – surprisingly – my blood sugar is now stable: it has been weeks since the last time I experienced food cravings at night, or feeling faint in the middle of the day.

Giving up caffeine was one of the best decisions I have made in the last few years.
