Shifty you must have missed out on Monk Fruit extract
best sugar "substitute" i could find on the market that adhere's to my organic rules.
As far as the rest of your post, fat macro is important. That's the only part i take issue with really. You dont need to "hit it" per se, but if your fat intake is less than your protein intake, you risk your body attempting to convert those proteins into glucose, which is going to cause your muscles to deflate and is going to make you feel like shit. It can also contribute to that "keto flu" you mentioned. The chicken broth isnt a placebo, it works because of the sodium content in the chicken broth, along with the fat content it brings.. Most people new to keto don't realize exactly how much electrolytes they are going to need. This mean add salt to everything you can, take supplements for (or consciously consume foods high in) magnesium and potassium.
Good thing to get used to doing is bullet coffee in the morning. This is incredible when you are first start keto. It's essentially coffee blended together with various fat sources of your choice. Mine is ghee and coconut oil with a little heavy cream. Blend that up high speed for about 15 secs and you get a 0g-2g carb frothy substance that can act as a meal replacement or a fat bomb. It's part of my daily routine.
