Couple of things you gotta know about keto first.
Shoot for ZERO carbs.
Try not eat too many processes foods.
KETO diet burns fat more than any other IMO.
!!!!!..EAT A DIET OF %75 FAT %25 PROTEIN..!!!!!!
Ok, now do you want to do a KETO or CKD variation of KETO??
I think that the CKD variation allows for greater maintaining of muscle and also adding some too in a alot of cases. In the CKD you carb up after going a week in ketosis...Let me know if you would like me to go into that...although im sure you could do a search and find a wealth of info.
On a typical diet your right you do need carbs to furn fat but KETO/CKD is not typical
You can achieve visible abs on ANY diet as long as you have trained them so that the abs are there loll...and your bf is low enough...im not sure where you got the idea that you had to do low-carb or keto to get abs??
NO SKIM MILK ON KETO
NO SOY MILK ON KETO
NO MILK PERIOD
If doesnt list the amount of carbs on package of food....and its not fresh meat/oil/fat...then DONT EAT IT....Even if it does, read ingredients cause alot of the "no carb" foods have sugars etc added but they dont list them. If it has sugar, corn syrup, etc..dont eat it. Get some keto-stix from pharm to check ketone levels...it may take up to 4 days to get into keto but after a while your body will get in quicker after carb-up(if doing CKD).
As for the heavy whipping cream its ok...but NOT .5C....that has enough carbs to keep you out or bump you out of ketosis...
Also why not just do BOTH cardio and KETO...your fat loss will be excellent if done right....just keep cals at or below maintence....i do 10 x bw.
