Weight is stuck at 52 kgs?

Don't get hung up on 500 grams a time, your weight will always fluctuate, because of intake(some foods are just heavier while in the body, than others), but also depending on water retention, because of hormone-levels, which are continuously changing, so ignore every fluctuation that's under 2-3kg's, and that doesn't last for more than 2-3 weeks.
