I know it's hard, but keep hanging in there.... Sounds like you are doing a lot right, I have been there too.... Then after a couple
of days pressing on with doing the right things, the weight drops a couple of pounds. Be sure you are getting enough sleep
too!

The last time I weighed in I had gone up in weight by 3 pounds but I had lost inches.

That means you're losing fat. The bootcamp idea and going crazy with exercise almost certainly caused your body to hold on to a bunch of extra water for awhile. And that's not a bad thing. If you lost inches, you did something good for yourself, even if the scale didn't reflect it. Over time that water would come back off and you'd lose weight too, but it requires patience. The first 6 months I was on keto I didn't exercise at all and lost weight extremely steadily. I decided to join a gym and start working on my fitness level, and my weight loss stalled for a full month. But in that month I felt great and lost inches everywhere. Eventually the weight started dropping again. I stressed about the number on the scale a little even though I knew I was doing something that was great for my overall health. That's natural. But really, the measurements tell you more about what's happening than the number on the scale.

If you've been in ketosis for a good while, you'll get back in pretty easily after a couple cheat days. Different people have different ideas about the fat fast, its probably not necessary but it probably won't hurt either. You're frustrated, and when you get frustrated its easy to push yourself to extremes to try to get the results you want. My thinking at this point would be to relax, get back into ketosis, and push for a couple good, consistent weeks, log *everything*, weigh things on a food scale to be doubly sure. Remind yourself, or post here or on r/keto on reddit for us to remind you that inches lost means more than pounds lost for your overall health and progress. If you continue to feel stalled out after some time, share your food log here and on reddit and get some suggestions.

What do you mean "Fat to satiety"

So I'll use myself as an example. My macros are set at 20g carbs, 125g protein, 160g fat. That adds up to about 2050 calories. So no matter what I want to stay at or under 20g carbs, that is the most important and most strict rule, obviously. Ideally I want to try to eat exactly 125g protein a day. Too far under that and I may start losing muscle mass. The fat, however, is really just an upper limit. The idea is to eat as much fat as you need to feel satisfied. If that happens to be less than 160g, great. Fewer calories and more weight loss, hooray!

I've recently had to play with my calorie goal, I was eating 2000-2100 each day and wasn't seeing much progress (according to Fitbit I burn 3-4k per day with my job) so I was advised to reduce my calorie goal as I've lost significant weight and am probably eating closer to maintenance at that daily intake. I reduced my calorie goal to 1700 and saw 3 pounds of loss on the scale at this week's weigh-in! I don't eat back calories from activity unless I'm really hungry, but I don't really get hungry anymore either, at least not uncontrollably so and can usually just drink some water and I'm good to go.
