No. Unless you’ve been specifically told by a physician that you need to reduce sodium intake due to high blood pressure or another specific medical condition, there’s NO reason or need to limit your sodium.
Your body loses a lot of sodium via sweat, especially if you live in a warm climate. It’s important to replenish sodium to support rehydration and for proper execution of essential functions within the body. A healthy individual is able to efficiently purge all of the sodium s/he consumes.
Absolutely. There is no limit or restriction on these, as herbs and spices contain zero calories.
That depends:
Add up all of the grams (in weight) of the protein and carb powders you put into your shake. Multiply this amount by 12.5, and that’s the amount of water in milliliters that you need to pour into the shake to make it the fastest-absorbing and most-hydrating 8% solution. For ounces, take that milliliter number and divide it by 29.6.
For example, if your protein and carbs together weigh 90g, then you’ll multiply that by 12.5 to get 1125mL of water for your shake. Dividing that by 29.6 gives you 38 oz of water.
