Cooking without oils

So I started to notice the people I follow cooking without oils and I have been trying it out. I use mainly lemon juice on the skillet when I cook tempeh or veggies. Sometimes I will do a tiny amount of olive or coconut oil on the pan and then squeeze lemon too. Then I'll season my food with sea salt and other spices. I actually really like the taste and for the most part, lemon goes fine with all of my bowls, salads and wraps etc. The reason for cutting out oils when cooking is because oils have a LOT of fat, like saturated fats. If you can avoid it, cooking with lemon juice or even vegetable broth is a healthy switch. Oils are very processed, and they slow your arteries when they are digested. While oils can be healthy fats, you probably are getting enough of those from avocados and nuts.
