How has fasting worked out for you?
Fasting is a strategy not a diet to mobilize fat faster since it forces you to ketosis faster when your insulin levels are low and you workout on an empty stomach, basically your body will target your fat stores instead of the carbs if you don't eat for a period of time because your insulin levels will be low, if you consume carbs it will target the carbs as a primary source of energy.
So you need to follow a calorie deficit diet to make fasting work.
The diet is the key the fasting is the strategy.
If you are thinking that you can fast for a period of time then go on binge eating overeating everything that you want you are severely mistaken, because it will never work, without a proper calorie deficit diet.
