I'm 1 year 6 mo post OP vsg, I'm considering keto, does anyone know what macros I should be following?

My first question is why you are choosing to do Keto? While the science is valid in the ketogenic diet producing positive weight loss results, the long term results are not sustainable. More over, those who stop Keto, usually do it incorrectly, and risk putting back on all the weight they lost through the diet.

Are you looking for a quick fix to drop some weight or a plan you can stick with? A diet that requires you to eat 75% of your meals as fat needs some serious consideration before diving in. Just my opinion.

Continue to do your research. Keto is safe. Many say it is not. But when you become fat adapted, you will burn fat. This means cholesterol numbers improve. Yes improve. I successfully reversed type 2 diabetes, lowered total cholesterol. Lowered LDL, raised hdl and lowered Trygliserides.

As far as macros, just start by reducing total carbs to 20. Start reading. Ketogenic diet is sustainable. Cracks me up people saying otherwise.

I don't do Keto myself (I am just unable to get the amount of fat in that is required), but I did some research on it a while back. I found this site a good first step resource (before you get into the more detailed, science-y stuff) :
