How long to ketosis after starting?
 

Once switching over to an Atkin's diet, about how long before my body would exhaust it's store of carbs/glycogen and start burning fat for fuel? I would hate to see my weight/waist climb while I'm eating high-fat foods, but before my body decides it wants to burn fat.

Fat doesn't make you fat, just remember that ;) Grams of fat have more calories then grams of carbs or protein so if you are worried you can count calories along with carbs.

For me it takes about 2-3 days to get into ketosis.
