Doug, I only did the food diary for a week. It helps to look objectively at how much food and what type of food I eat normally. It's just a data-gathering exercise to look at my current normal situation before taking proactive steps to improve my eating habits.

One of the Van Tulleken doctors - it might have been Dr Xand - in a TV documentary carried a bucket around with him for one day. For every item of food he ate, he put another one in the bucket and then a scientist analysed it for calories, fats, sugars, etc or something like that. I'd rather a nice discreet little diary or an app on the phone. LOL
