That sounds good.
I would say eat good three meals a day (until you feel you naturally don’t want to - don’t force it), keep the carbs low, get plenty of fat, get enough salt, and don’t count calories. You’re going to be doing this a while - you don’t want to be hungry or feel deprived. You want to enjoy and look forward to your meals. Make sure you eat enough and eat things you enjoy.
It will work; you will see.
Before my weight stabilized, I had an episode where after two weeks of not losing much, I got on the scale and found that I weighed 20 lbs. (9 kg) less than I had the day before. That was my only big whoosh, but it just goes to show that you never know. 
I wondered about 20 pounds in a day also.
That seems like a lot of time in the bathroom - 1.25 pounds of something per hour for each of 16 waking hours.
I vote for scale error!
OMG 25 to 30 pounds in 4 to 5 weeks?
Oooh that looks like automatic regain type of weight loss?
Wish I could have lost that much body weight in such a short amount of time?
4 pounds a month would be more reasonable?
That scale will fool you real quick with muscle gain!
I’ve lost 5-7 pounds when fasting a day, many times. But 20 might be a little tough for one day.
I refused to believe my scale until it continued to report the same lower weight for nearly two weeks.
Whooshes are fairly common on a ketogenic diet, however, and from what I’ve read on these forums, 20 lbs. is by no means the largest amount possible to lose in a single whoosh.
The hypothesis I’ve read on these forums is that fat cells fill up with water to replace the missing fat, until the day comes when they decide they’re not going to get the fat back, so they let go of the water all at once. This explanation makes no sense to me, though the phenomenon itself is undeniable.
Welcome @bp52 glad you are here! Be patient with yourself and give it some time.
Gosh that’s almost the only explanation that makes sense. 10 days the scale goes up and down over the same 2 pounds. Then all of a sudden, down 3. Overnight. woosh 
Now if we could just figure out the trigger we could have the steady plodding weight loss we all count on.
Please know that not everyone is losing those crazy amounts. I am only losing a half a pound a month. So I had to rethink this whole thing. Progress not perfection. As long as the scale keeps going in one direction I’m ok. I also believe it will stay off if it goes slow. Whatever keeps me in the game. 30 pounds and going.
And I stopped losing after sixty pounds or so, and have been cycling up and down pretty much within the same ten-pound range, ever since. Although my pants have loosened up a bit, so I’m clearly still losing some fat, whatever is going on with my bones and muscles.
My primary goal was to reverse pre-diabetes, and that happened pretty quickly. The fat loss has been a nice side-effect, I have to admit, and I certainly wouldn’t complain if I were to lose a bit more weight. However, I can now do all the things that being obese had taken away from me, so if I’m still this weight when I die, I’ll die happy.
