On Charles Clark diet again after 9yr gap. Lost 3st before. But like a fool didn't stick to the maintenance phase so 2 st came back on an sat there for much of the last 8yrs. Got his latest book an read again. Started two weeks ago but after an initial 3lb loss my weights been going up and down. Didn't happen like this at all last time. Re read the book an noticed I should cut out all caffiene including diet Pepsi an restrict milk in tea. So cut out all Pepsi an black tea substituted for mint tea an water. Bit boring. Has anyone got any suggestions?
