Unpopular opinion from a sports dietitian: most people don’t need added electrolytes and here’s why 👇
Water is often enough for the vast majority. If you are dehydrated, it’s probably from lack of fluid..not lack of electrolytes. Oral “rehydration solutions” (LMNT, Liquid IV, etc.) will help people that are dehydrated and sweat excessively to rehydrate. During exercise, you lose fluid + electrolytes through mostly sweat. Research consistently shows that performance deficits begin when you are losing around 2% of your body weight from dehydration (cardiovascular strain rises, perceived effort increases, endurance performance declines, etc.)
But here’s the nuance most people miss: most workouts won’t get you to that point of dehydration.
To reach that 2% body mass loss, you typically need:�⏱️Longer duration (60-90+ min)�💦High sweat rates (often 1–2+ L/hour)�🥵Heat/humidity or high intensity
It’s important to state that added electrolytes DO matter…when physiology demands it. HOWEVER, if you’re mostly at a desk, doing short workouts, or just trying to “stay hydrated”…you’re probably not losing enough sweat to meaningfully deplete electrolytes. The avg diet already provides more than enough electrolytes to replace losses. �
🍉🥬🥛Instead, eat whole food often and aim for 1/2 your weight in ounces daily of fluid! Let’s try not to solve a problem that we don’t even have! Save your money and drink water with lemon if you need to spice it up 😉
