Hi Elly,
I can't see anything wrong with the food you're eating, except that maybe you're not having enough.This is all I could think of:
- Are you weighing/measuring your cereal? I was shocked at just how many calories there are in some cereals and how small a portion is supposed to be

- Do you ever bulk out your evening meal with extra veggies/salad? I do this a lot and it helps me to fill up and get my 5 a day (can also help with constipation etc)
- Looks like you're drinking plenty of water, so no problems there
- what about soups / wraps / pitta breads at lunch for a bit of variety? You can get some very low calorie ones if you look around, and pile them with salad and ham/chicken.
- Do you like stir frys? Blue Dragon do a good range of sachet sauces that are low in calories, and you can have them with veggies/chicken and noodles.
- Have you tried any low fat home made currys/chillis and that kind of thing? There are a few recipies on this forum that you could try out.
I think any of these things will probably increase your calorie intake slightly, but in your case, you might need to eat slightly more, or to have more variety to get things moving a bit.
I know how disheartening it can be, but it may just be your body adjusting to these tablets. In which case, it's just gonna take time. All you can do in the meantime is to give your body everything in needs in terms of nutrition and water, and just wait for the results!
Have you tried
myfitnesspal.com? they have a good calculator to work out how many calories you should be having each day. You can also complete a food diary on there that works out all your daily nutrition intake.
Good luck - I really hope it works out for you x
