I've never heard of ketosis happening that fast generally being 2-3 weeks. A lot of this is possibly to just align hormone levels (can't exactly recall the science) so that you respond to them more efficiently.
I don't even think CBL is true ketosis anyways. At least not once you start backloading. I think my buddy who is big on keto (just went through cancer) loves to talk about true ketosis and all that.
Personally, what I am doing now is basically 1-2 protein shakes before training. One when I wake up, and one before workout. I've gone back to eating a breakfast of 4 eggs and a 1/4# of chopped ham mixed in (4 slices). Having the eggs and ham has helped a lot more than trying to just make it through my sessions on 1-2 servings of my protein (30g of whey, 9g of carbs [probably should find a protein with half that] and is 180kcals/serving). Sometimes I only get 1 serving before and on Saturdays, I tend to go in on one serving or protein to make it to the gym before it closes early. I skip the eggs and ham (though it makes up really fast) and generally have enough energy to get through.
At night, I eat whatever. Yeah, I'm not too strict about that but no junk food, no soda. Veggies, protein, carbs. I train M-Sa. Sunday, I tend to do jack except maybe some BW stuff/calesthenics which I also sometimes mean to do at nights. I ride a bike to the gym because it's close, and helps warm up and cool down and get some aerobic work. No, I don't ride remotely hard at all. I get sweaty because it's hot and there is some hills on the way to the gym (which makes TigerBalm work even better).
I drink about a gallon of water/dayor even more and pop a caffeine pill or 2 cups of coffee when I wake up. Sometimes, I'll pop a zero cal redbull instead or along with if I'm feeling not so energetic.
On a competition taper, I do something more carb nite/no carb ish. It's pretty easy for me to just eat protein and make it through the low volume and %.
Right now, I'm over my weight class but my next meet isn't for months. I weigh myself at the gym and try to keep in mind how much fluid I've drank and peed and I have no idea what eggs and ham might weigh.
Also, sometimes I suck on a cough drop midworkout which is 4g of carbs so it's probably just enough sugar to get me through. I used to pop them more often but I try to not at all or just one.
Weight is coming slowly off based on the daily weighins. Not as fast as carb-nite. But it's not bad, especially with the extra protein meal. I feel really good going in on 2 servings of protein and that meal.
Caffeine is essential. I also get about 5-7.5g of creatine/day from my protein mix besides whatever I get from protein (150-200g/day). I have tried this without caffeine and creatine (protein mix did not have creatine in it) and it really sucks.
Also to note, I generally only do 1 lift per day with some pulls and backoff sets and super low volume squats at the moment. Jerk days include press work but more sets with just 2/3's. I'm not doing 5rep sets or 10's besides some work with DB/BW/pulldowns. I have combined Sn and CJ on some days and it's been alright as well but not a high rep count.
Earlier this year I was on a different program and I could get through on 2 servings of protein prior at the beginning stages of the program but eventually added in a small solid meal of protein, fats, and carbs to continue hitting my prescribed numbers besides snacking on a granola bar preworkout and raisins during. I had hoped to lose weight at that time and basically that plateau'd to continue the program.
When I first started WLing a few years back, I tried doing IF and eventually found trying to hit all 3 lifts plus volume in strength work would just make me gas out halfway or past halfway in. I'd then start eating a granola bar or raisins to get me through and eventually I just quit this because I kept gassing out. Similar thing of protein preworkout with a 4-6hours eating window with 2 meals afterwards.
In about 6 weeks, I will be changing up my program since I'll have 6 weeks till competition. So that will mean something that hits both lifts with pulls/presses most days besides maintenance squats after. We'll see how that goes in August.
