Why Potassium Matters on Low-Carb and Ketogenic Diets
On a low-carb or ketogenic diet, your body sheds water and critical electrolytes faster than on a standard diet. Potassium is one of the most important minerals lost, often dropping below the 4,700 mg daily target recommended by health experts. This depletion contributes to fatigue, muscle cramps, heart palpitations, and the dreaded keto flu. In my book The CFP Weight Loss Method, I emphasize restoring potassium early to prevent these issues, especially for adults over 45 dealing with hormonal shifts and joint pain that make starting any new plan feel overwhelming.
Many beginners fear potassium chloride supplements because of past failed diets, but when used correctly they become a reliable tool. The average American already falls short on potassium, and cutting carbs reduces intake from fruits and starchy vegetables even further. Replacing lost potassium supports stable blood sugar, healthy blood pressure, and better insulin sensitivity—key concerns when managing diabetes alongside weight loss.
