Also: don't pay anyone for keto, it's simply a low carb/high fat diet. Everything you need for it can be found for free online and at the local grocery store.
RedWulf is right: you don’t need to spend ANYTHING to learn how to do keto. It’s all online.
Some surprises I found you can still be in keto while eating a dessert each day. I was doing VLC while pregnant and was so healthy. But my doc didn’t like me not gaining enough weight so he made me eat ice cream every night. And I stayed in keto.
However, starting is very difficult. You have to adjust and the first 4-5 days will have powerful cravings for sweet things. But after those first few days, those cravings are GONE. Make sure to eat some fiber every day, powdered and/or from fibrous veggies. Cooked is fine.
