I think it varies for most people. For me, I saw a quick 10-15 lbs drop over the first 2 weeks, then a steady 10 lb a month drop over the next 6 months. Results will vary depending on your activity level and how much you need to lose. During the same period where I lost 60 lbs my brother lost 30 following almost the same food regimen but he had a lot less to lose then I did. Just remind yourself that it didn't go on overnight and won't go off overnight..it's a journey. When you all of a sudden start feeling a ton more energy...that's when you'll start seeing more weight loss. That's when you're in a good state of nutritional ketosis and all the sugar/frankenfoods crap has left your system. Takes a good month or so for most people. Keto on!

I have never felt a loss of energy during keto. It is always accompanied by an energy increase, mental clarity, and feeling better about myself (loss of depression). But every body is different. I'm not an athlete. My life is quite sedentary.
