When it comes to burning fat, you might think of strenuous exercise and dieting, but understanding Resting Metabolic Rate (RMR) is also key!

Don’t underestimate RMR, as it accounts for 60-75% of daily total energy expenditure. This means even if you don't exercise, most of your calorie burn is determined by RMR (though we still recommend maintaining an exercise habit!). Therefore, for those managing their weight, understanding and boosting RMR becomes very important.

Resting Metabolic Rate (RMR) is the energy your body needs to maintain basic functions while at complete rest, including breathing, blood circulation, and temperature regulation. In other words, even if you lie on the couch all day binge-watching shows, your body still needs to burn some calories to sustain these basic functions.

Several factors affect RMR, including age, gender, body composition, genetics, and hormones. More muscle mass means a higher RMR, as muscle tissue requires more energy to maintain. RMR gradually decreases with age, which is why many people find it harder to manage their weight as they get older. Men typically have a higher RMR than women, mainly because men usually have more muscle mass. Genetics also play a role, with some people naturally having a higher metabolic rate. Additionally, thyroid hormones significantly regulate RMR.

Can Drinking Water Increase My Resting Metabolic Rate?

So, what role does water play in this? Can drinking water really help you burn fat?

Drinking water can help you burn fat more efficiently. When your body is well-hydrated, metabolic processes are more efficient, and the rate of fat breakdown increases. This is because water is involved in many metabolic reactions, including fat breakdown.

Many studies support that drinking water can increase RMR. For example, one study found that drinking about 500 milliliters of water (about two cups) daily can increase RMR by approximately 24 calories.¹ This means that drinking more water every day can help with fat burning and weight management over the long term.

Additionally, water intake can cause a phenomenon known as "water-induced thermogenesis." Simply put, when you drink water, your body needs to expend energy to heat the water, which burns extra calories. When you drink a glass of water, your body uses energy to bring the water to body temperature. While the energy used is not a large amount, it adds up and can be beneficial.

Drinking water also helps control appetite and reduces unnecessary calorie intake. Sometimes, the feeling of "hunger" is actually "thirst." Next time you feel hungry, try drinking a glass of water first and see if the hunger persists. This way, you can avoid unnecessary calorie intake, further aiding in weight management.

Drinking water not only quenches your thirst but also helps you reach your health and weight management goals more easily. Remember, the next time you feel hungry or tired, drink a glass of water to keep your body in optimal condition.
