Hi Kimkai – my advise would be to check how you are using your calories, as not all calories are equal. Take a look at the carbs that you are taking in with the calories and try to get them at about 50g or less a day. Include some good fats in your cals as well, as this will help to kick start the fat burning process.
Try not to be too disheartened and stick with it – logic says that if you are on 800cals a day, the weight has to drop at some point! It will happen, it’s just that we are all different and lose at different rates. Like you, I lose slowly. It is frustrating sometimes, especially when you read of folks losing pounds and pounds each week, but try not to see the success of others as your failure. You will have positive results soon, so embrace them when they happen and use them as a stepping stone to your next achievement.
Good luck … we’ll look forward to reading you positive results soon.
