This morning I weighed 66.7kg! That is a lot of weight to put on in one day! Fortunately, I know that what the scale says is not necessarily true. I also know that last week I created a deficit (through exercise) of 1110 calories and I have not over-eaten either. So, what the scale says is RUBBISH.
I think I need one of those special scales that measures fat and lean body mass - the method of dividing body mass by height to find body fat % is ineffectual. I just have to learn to understand that I don't always have the right tools or measurements at hand. All I know is that 3500 calories equals 1lb and as I work up to those calories, the weight will shift. Anyway, that is the theory and I suppose, like all averages, it will be different for everyone. Let's see how it works in practice!
