Both weight gain and weight loss can cause you to skip your period and can help regulate your period.
Your menstrual cycle is a result of a complex interaction between your ovaries and your brain. The coordinated changes in your hormone levels cause ovulation, and if you don't become pregnant in the days around your ovulation, more hormonal changes result in your period.
Anything that interferes with this interaction can stop your body from ovulating. If you miss an ovulation you will skip your normal period.
What happens to your period when you have a significant fluctuation in your weight depends on what weight you are starting from. For example, if you are starting at a normal weight, gaining or losing weight may cause you to skip your period. While, if you are underweight or very overweight and not menstruating, gaining weight or losing weight will likely restart your regular period.
