Hi dear, yes the irregular period cycle & skipping your periods is due to increase in body weight, particularly body fats. You firstly need to visit a good gynecologist & get yourself assessed for your hormonal profile, blood sugars, insulin,
thyroid, etc.
Next Steps
As of now start modulating your lifestyle by starting these changes- 1. Have healthy home-cooked food made in less oil &
sugar. 2. Avoid processed, junk, fried, sugary foods. 3. Improve your physical activity 4. Have a good liquid intake. Weight loss & hormonal imbalance is a gradual process hence I would recommend a strict fat reduction diet & exercise under an experience, wherein you will gradually see the difference in your weight & thereby improve your menstrual cycle!!
