Sorry to hear you're struggling I don't know if perhaps your weight gain is triggered by medications? I'm on quite a few medications and I find any time I have dosage adjustments or changes in drugs I seem to gain weight. I'm also trying to lose weight at the moment. I feel your pain. It's certainly a journey. Just keep trying though and see what works for you. Also if you're only on 1000 calories per day it may not be enough to trigger your body to drop the weight. I say that because I was watching a show today where a trainer was discussing the importance of not starving your body of calories to lose weight and how you need to eat the right amount of calories to fuel your body correctly to drop the weight. Also he mentioned that starving the body is also starving it of nutrients. It's something to think about anyhow. I wish you the best.
