How to lose weight

Hello there, I am 30 years old, female from India, and I was struggling with a weight loss challenge. I heard about intermittent fasting so I searched on YouTube and found Dr. Berg's channel. As an Indian, it is hard to follow all Keto for me, so I concentrated on Intermittent fasting. I did twice in a week dry fasting, and regular 1-hour exercise, 5 days in a week, and tried to balance with vitamins and minerals. It is hard for me to skip rice from the menu (due to hot and humid weather and it is a staple diet) but tried to follow other tips. Though I had no consistency due to my workload, but I am happy to reduce 15 kg in 8 months. Thank you doctor.
