Eat your veggies.Especially green ones. Spinach in your salad will up your potassium, and some broccoli too. My hubby was skimping on the salads and he got charlie horses, while I never had any problem ( I had all the salad stuff here at home) Do a google search on potassium and vegetables, you'll see a huge variety. Even some nuts like Almonds, pecans, cashew, brazil nuts have potassium.

One other thing, the Atkins Advantage Shakes have a good bit of potassium, and only 1 net carb. You could have one of those for breakfast .
