Brief Answer:
Better increase physical activity and lower the calories intake.

Detailed Answer:
Hello dear welcome to Ask a doctor's service.
I read your query and here is my advice.

Fasting is widely used for weight loss but it is not scientifically proven to be accurate.
Fasting puts your metabolism to fat burning mode but also lowers your basal metabolism so you burn less calories than usual.
Also you may intend to eat more calories when you start eating because of hunger and store them quickly.
The most appropriate way for weight loss is to reduce the calories and increase the physical activity.
Also choose better the food you eat.
Eat more fruits and vegetables, lean meat, less carbohydrates and fats.
Drink two litres of water per day.
Increased physical activity, swimming, walking or gym.

Hope I have answered the questions.
Let me know if I can assist you further.
