Tag: O2

While the human body requires oxygen to burn calories for energy, the oxygen molecule itself contains zero calories. So, how many calories does O2 have? This fact is fundamental to understanding metabolic health and the role of fuel versus a reactant in energy production.

According to the World Health Organization (WHO), oral rehydration therapy has been a global success in reducing child mortality from diarrheal diseases. For individuals seeking to replenish fluids, the question often arises, **should I take O2 on an empty stomach?** The answer is more nuanced than it appears, largely depending on whether 'O2' refers to a hydration product or a medication, and how your body responds to rehydration solutions.
