Hi @Hoody and welcome!
It's always nice to have immediate loss, and there could be a number of reasons why you are not showing a loss now after initially doing so. Often initial loss is mainly water associated with storage of glycogen in the body, which tends to be the first energy source the body turns to when calorie deprived. Once you have lost that, observable weight loss can slow, as now the body needs to convert fat to energy and loss of fat can be masked by the daily ups and downs of total body weight. Also the body can be adjusting itself so that fat loss shows via the tape measure rather than the scales - so if you haven't already, do take lots of body measurements and monitor these every few weeks too. And take some photos as well - everyone always wishes they had a before photo once they reach their goal!
Have you read this information from the library? It gives you lots of insight into the vagaries of weight loss!
