This is a well thought out and excellent aid to dieting. It makes one well aware of the calorie values of whatever you choose to eat. There is only one area which I query and that is the one of age and the calories needed per day to 'survive' and/or to lose weight. I am nearly 80 and one's metabolic rate is totally different to that of younger people. I am only losing weight if I cut the daily calories substantially below your recommendation. None of my friends over 75 are able to lose weight on average calorie intake. Comments on this aspect of dieting as related to 'seniors' please.
