where am I going wrong?

Hi

I'm 42 and currently stuck at 160 lbs, I have lost 15 lbs since june but weight loss has been slow.

I have medical complications - underactive thyroid from birth (never worked) on 300mcg daily also on anti-histamine to reduce severe allergic reactions to stuff (even things I have eaten before) I've survived full anaphylactic shock twice from peanuts and Ibuprofen both of which I had eaten before but my immune system gets affected when thyroid levels drop.

I also have a rare neuromuscular disorder which is Ataxia (balance of trunk and co-ordination of limbs and Dystonia (mixed muscle tone - sudden stiffening of arms and legs then floppy or anywhere inbetween) and involuntary flexing of hands making it difficult to hold onto stuff for any length of time without dropping or letting go ie weights, walking aids.

Despite these difficulties I've managed to find some games on wii I can do and by combining games build up a little routine.. today I managed 120 mins.. I use quarter pound wrist weights on arms (to steady them as well as for fitness effects), half pound weights on ankles and wear a sensory balance belt around waist (6lbs) to help me keep balance enough to do the exercises. I push my body as hard as I can and dropped wheat and gone low carb so mainly eating salad, veg with portion of fish or meat a day. I have Rice Krispies or oats for breakfast, but limit gluten free bread to once a week)

I'm trying apples and water today as I'm desperate to get into the 150's for my next weigh-in, but seem to be stuck. Today I got in knickers size 14-16 first time for years, my 18 trakkie pants are getting baggy, just got some 16's so must be losing but the scales are hardly budging!

I have an injury from last week and back of my leg is still swollen I wondered if could be water retention from muscles to heal, but seems to be holding onto it a long time?

I changed to 1 lb loss a week but its only gone up from 1200 to 1290 on here. I don' t log food on here cos I've had problems with custom foods it won't accept the weights I put in under portions if I can't find exact weight already on somewhere, so use a different one.

But as mentioned above its a lot of veg and portion of fish or meat, with salad at lunch and rice krispies or oats for breakfast, occasionally I throw in rice or a potato but most of week substitute them with cauli rice for example or butternut squash slices, mashed swede in place of potatoes.

I don't understand why the weight's not dropping off especially as I get involuntary movements throughout the day, even if not exercising so I never stay completely still for longer than a few minutes unless I'm fast asleep?... so I must burn about 1,000 a day at least with exercise too (today burned 643cals between 5-7am)

Any ideas?
