This isn't about losing weight. Fat burning is what your body does to fuel your body when you're not eating.

Most people do not eat healthy fats nowadays and instead eat seed oils, which cannot be stored and burned later for energy. So many people physically cannot fast. So if you only eat healthy fats, you'll have an easier time fasting without even thinking about it. 

 I only use olive oil. Sometimes, from time to time, I use almond or avocado or sesame oil, add it in the end, when food done, or in salads. I know that fasting helps our body to regenerate and burn those invisible fats...is what I want.  🖖😃🫂
