Since being serious about losing weight since Christmas I have lost around a stone and am now 13 stone 12 pounds this weekend. The only drinks I've been having are water throughout the day and at night, plus decaffeinated coffee (café hag or arte noire expresso in the tassimo machine with the tassimo milk) in the evenings, in addition to water. I don't drink milk, but do have skimmed milk in porridge. I've read a few articles which suggest that decaffeinated coffee isn't healthy, although this appears to depend on the decaffination process used. Having the coffee in the evening helps me, because in the past I would just snack on crisps, cheese, pringles etc while watching films or reading, whereas now I feel quite satisfied with a couple of mugs of coffee. Normal coffee affects my sleep, so that's why I'm drinking decaf. Does anyone else drink decaf?
