Oh my , hope you are beginning to feel a bit better Ladyluck xx
The bariatric plate looks useful. The problem I have with my fitness pal is things like homemade casseroles and the like that contain loads of different veg, meat etc (I tend to judge ingredients by slimming world recipes to avoid fat/sugar etc. I do loads of slow cooker stuff as it suits my work hours best, but it's hard to judge calories like that so a lot of it is guess work.
I've just discovered if you log in to my fitness pal on the computer rather than the app and click on food at the top there's a recipe builder where you put in all your ingredients and how many portions you're making and it calculates it for you! Then it saves it under recipes and on the app you can add food from recipes and your own creations are stored there. It's been a great discovery for me as I was worried about portions etc but thrilled to discover my beef hot pot was only 312 calories per serve with 26g protein, I'd tried to add it up and it wad much higher!
