Arghhhhh.... Honestly Kathy I'd really not worry about metformin again. At least since I started taking it again I have put on no more weight and I have not changed my way of eating.
I do not eat lots. I rarely have brekkie and if I do it's a slice of Burgen spread with butter and Marmite (other spreads are available but Marmite
is virtually no carb - 0.8g per serving and you seriously cannot overdo it as it's fierce stuff!). Lunch, some sort of home-made soup in this weather, with 2 slices buttered Burgen (12g per slice). Soup might be carrot and ginger, pea and mint, broccoli and blue cheese, roasted squash, mushroom with a dash of sherry. Nothing that comes up much over 15g carb per portion. Dinner will be meat or fish with a good selection of veggies inc green leafy ones and since Xmas I have cut out all potatoes/starch and am doing things like celeriac dauphinoise, swede mash, cauli mash or rice etc. Tonight I have gone a little OTT with home made Chicken Tikka Masala and Tarka (Lentil) Dahl, but I shall only have a small portion. Cannot seem to lose though so you do have my sympathy!
Particularly since I caught sight of my back in a mirror in a changing room this afternoon whilst I was buying a nice tent!
