Being in ketosis means you are burning fat for energy. If your calories are too high and you are eating too much fat, that may be what you are burning for energy and your body may not need to go into its fat stores. Therefore, it is possible to be in ketosis and not lose weight.

However, you don't want to let your calories get too low. If your body thinks it is starving, your metabolism will slow down. Each person has to figure out for himself or herself what he or she can eat and still lose weight.

Since you are only in day 5 of induction and you don't have much to lose, I'd wait before making any changes. Some people don't lose anything during the first week of induction and then drop several pounds during the second week.
