Why does thi keep happening?!?

Time of the month, hot days, cold days, what you ate 2 days before, tons of reasons for the flux in weight. If you skip a meal, your bod will hold onto food. Kepp eating small healthy portions 3 - 5 times a day, 20 min's on tred or bike and you will be great! It's very common to flux 5 pounds up or down from day to day
