so who does Keto here

can u do it long term, or is it just a fad diet

I just started, so far I really like it. It's a modified atkins plan imo

Dont do it beyond 6 months...by then you should have hit your weight loss goals...to come off it, eliminate all the oils, animal meats, dairy & eggs...and eat everything else you enjoyed during your weight loss journey.

If you do that, you will likely be +/- 5lbs for the rest of your life.

I wouldn't strive for a Keto based diet. You can have a similar effect with any low-carb diet without worrying about dropping out of Ketosis. I could go deeper into the subject if you like.

It is not easy to get your body in ketosis or to remain in ketosis once there. I'm willing to bet 99 percent of the people who claim they are on keto are not in ketosis. 

I've tried a few times, but I can't say I'm thrilled. It is not suitable for everyone, there are many contraindications. It is also necessary to understand that there are simple and complex carbohydrates, and just simple carbohydrates should be avoided. If you do it right, keto is good for you.
