This post deals with the ketogenic ratio which determines if your meals are ketogenic:

That is the ratio of foods that raise ketones vs. the foods that lower ketones, i.e. produce glucose.
Ketogenic Ratio (KR) = (Fat * .9 + Protein * .46) / (Carb + Protein * .58 + Fat * .1)
Ketogenic Ratio Description
< 1.0 Not ketogenic, if healthy you won’t register ketones
1.0 – 1.5 Mildly ketogenic, you may register ketones at this level
1.5 – 2.0 Ketogenic, most people will register ketones
> 2.0 Very ketogenic, you should definitely see ketones in this range
This does not take into account the energy expended by body fat being burnt once you are keto adapted.
This link looks at this problem Lucas Tafur: Total Ketogenic Ratio (TKR) but to be honest there are too many unknown variables (read the link) to know how accurate it is. The author suggests that whilst the KR ratio underestimates, this one overestimates so its snot really worth worrying about.
Taking my current macros of P 55g.C 6g Cals 135 0 (thus giving me F 123g)
KR = (123x0.9+55x0.46) / (6+55x0.58+123x0.1) = 2.7
If I use the same Pg & Cg but my old cals of 1130 (giving me F 98g) I get
KR = 2.4
So the next question has to be ‘what is the lowest Fg that I can use to give KR>2.0?’
Using my little macro calculator I end up with P 55g.C 6g F 69g Cals 865.
NB: This would represent the numbers for my macros if I was taking the low cal route with no blood ketone monitor to check & probably a DD on JUDDD (note to self – need to read a bit more on JUDDD nearer the time)
Final question is ‘.what is the lowest Fg that I can use to give KR>1.5?’
Using my little macro calculator I end up with P 55g.C 6g F 45g Cals 645.
NB: This would definitely be the lowest I would go on any protein sparing modified fast or possible JUDDD DD
