Hi Tommy
You’ve gotten loads of good advice already. Here’s some more:
- Keep it simple.
@ZuleikaD was spot on when they basically said the same thing. It can be overwhelming when so much complicated (and at times conflicting) advice is thrown at you all at once! People really do care, and I’m convinced we all here just want to help, and want you to be successful. But… Keep it simple, okay?. You can tweak it later.
- First, get fat-adapted. THEN worry about being “in Ketosis”.
This will simplify things. And once you are fat-adapted, that sweet tooth and cravings will calm down. So when you feel hungry, you just ride it out a little bit (maybe with a glass of water) and your body will visit some of that “stored energy” we have hanging around and burn it up as fuel. Honest, it won’t be that hard LATER to do that, once you are fat-adapted.
ZuleikaD was right: One step at a time.
And: “This is a big part of the equation. We get that people aren’t perfect, but until you’re truly fat-adapted (no more cravings!), every time you “take a day off” you set yourself back several days.”
- About the night time eating: Make a deal with yourself, and keep it.
This is just speaking from experience. I was the classic, hard core night time eater! A few years ago, my top weight was 460. Dieted, lost and regain, repeatedly over the years. Went low carb, then eventually Keto. Eureka, this stuff works! But… I’m now 68 and for some people, it’s slower going the older we get. Anyway, I’ve lost 199 pounds now. Yep, 199 gone.
A BIG part of that started with a deal I made with myself about that night time eating. For the first YEAR or so, I bought the best tasting sugar free chocolate bars I could find. Expensive?? Eegads, yes. But that was my deal. I would have that each evening with a cup of hot tea, and that would be my treat, cost be hanged. It felt luxurious. It felt indulgent. And it worked! Nowadays, the expensive chocolate lasts me a LONG time, so in the long run is not that expensive anymore.
Here is my current favorite (just in case the idea appeals to you):
Then again, you might be a bacon n egg kinda guy! 
- LOVE Dr Berry’s videos. LOVE Dr Fungs videos and book, The Obesity Code.
Here is my all time favorite Dr Fung quote. It says what I need to remember in a nutshell:
“The secret of success is NOT to limit some of the calories all the time (deficit dieting), which lowers metabolism. Rather, to limit ALL the calories SOME of the time…… which is called Fasting.”
PS: It is highly recommended to do fasting AFTER becoming fat-adapted. Much easier! 
My best to you,
Retta
