Keto diet

I love meat so I think keto diet can be good for me:) . 

I know you eat meat but do you still can eat potatoes or pasta?? I wonder how long I should use that diet to see effects ?? If I stop will there be yoyo effect after?? Should I see doctor or diabetic to talk about it first?? Is there any side effects of using this diet?? Can I have any health problems ?? 

I am very sceptic about keto diet but why not to try??😊
