I am not sure what abalation surgery is. I had brain surgery a year ago
Um Basically the most important is not to go over 100 carbs. I never let myself go over 93 though just in case. I tend to go from 1000-1200ish calories but I never ever go over on carbs. I believe this keeps me in super mild ketosis but I could be wrong.
I try to stay under 35g of fat a day but over 20g (for gall stone health) and make sure i get at least 85g of protein a day (usually its over 100). At least 15g of fiber. If I don't get that I have either stool softners or flax seed for its health benefits (just dont be bad like me, get the milled and expect it to be seeds. I need to buy some seeds since i dont like powders lol.
If you use a powder sugar free supplement like benefiber be aware they have around 4g a packet and are VERY sweet if you make as directed.
I also pop a daily vitamin and on occasion when I remember take a calcium/vit D supplement because I am lactose intolerant and have hypothyroidism I can have lower levels in those- but I am bad at taking them. I take a handfull of pills already as it is so its hard to force myself :P
