That shouldn't be too much, considering that a banana has about 500 mg of potassium and a potato has something like 750.

Don't go taking 7 potassium pills, though.

One thing that can deplete your potassium is going crazy on the water. Yes, you have to drink a fair bit when you're low carbing, but don't go overboard. Don't force yourself. Enough is good, more-than-enough isn't.

Too much sodium won't help, either. Try to minimize the prepackaged meats and stuff like that.

Try to cook your vegetables by steaming or microwaving, instead of boiling.

Just throwing out some suggestions.
