For weight loss, drink two glasses of cold water on an empty stomach several times a day.
Drinking 2 cups (0.5 liters) of water causes the adrenal hormone noradrenaline to surge into your bloodstream, raising your metabolic rate by up to 30%, just as if you had smoked a few cigarettes or drank a few cups of coffee. . % in less than an hour, as shown below and at 0:22 in my video “Optimize your water intake to lose weight.” When tested in a randomized controlled trial, it was found to accelerate weight loss by 44%, making drinking water the safest, easiest, and cheapest way to boost your metabolism.
Now, if you are taking beta blockers, this whole strategy can fail. (Beta-blockers are typically prescribed for heart disease and high blood pressure and tend to end in the letter lol, such as atenolol, nadolol, and propranolol, and are sold as Tenormin, Kogard, and Inderal, respectively.) Below and my At 0:59 in the video, see when people are given the beta-blocker metoprolol (sold as Lopressor) before drinking 2 cups (480 mL) of water.the increase in metabolism is effectively prevented. This makes sense because the “beta” blocked by beta blockers is the beta receptor triggered by noradrenaline. Otherwise, drinking water should work. But what are the optimal doses, types, temperatures, and timing?
Just one cup (240 mL) of water is enough to activate the noradrenergic nerves, but drinking two or more cups (480 mL) will provide additional benefits. Remember: Do not drink more than about 3 cups (710 mL) of fluid per hour. This is because your kidneys begin to handle more water than they can handle. If you have heart or kidney failure, your doctor may want you to avoid drinking any extra water, but even if your kidneys are healthy, drinking more than three glasses of water per hour can damage your brain. The electrolytes in your body begin to dilute significantly, with potentially serious consequences. . (In How Not to Diet, I talk about a devastating and harrowing experience I had as an intern in a hospital. One patient had committed suicide by drinking water. Suffering from a neurological disease that causes thirst, I knew enough to order.His fluids were restricted and the sink was closed, but I didn’t turn off the water in his toilet. I didn’t think so.)
Let’s get back to the topic. What kind of water are we talking about? Does it have to be plain water? It shouldn’t matter, right? No matter how flavored or sweet your diet drink is, isn’t water still just water? In fact, it’s important. If you’re trying to prevent fainting before donating blood, drinks like juice aren’t as effective as plain water. If you want to avoid getting dizzy when you stand up, water helps, but adding salt to the same amount of water doesn’t, as you can see below and at 2:40 in my video. what happened?
We used to think the trigger was tummy tuck. When we eat, the body shifts blood flow to the digestive tract by releasing norepinephrine to draw blood from the extremities. This is called the gastrovascular reflex. Therefore, drinking water was considered a calorie-free way to stretch your stomach. But if you drink 2 cups (480 mL) of saline (basically salt water) instead, the metabolic boost disappears, so gastric distension alone can’t explain the water’s effects.
I now realize that our bodies seem to sense osmotic pressure, or the concentration of substances in fluids. Detection of plain water versus another liquid was demonstrated by monitoring the production of sweat, a surrogate for noradrenaline release, when liquids of different concentrations were smuggled into people’s stomachs via feeding tubes. . Since we see less release of noradrenaline in liver transplant patients (patients who have had their liver’s nerves severed), it is possible that this is a spinal reflex, either preserved in quadriplegic people or taken up by the liver. There is a gender. Either way, our bodies can tell. Did you think we only have five senses? The current number is over 33.
My Daily Dozen recommendations rank certain teas as some of the healthiest drinks. After all, they’re all water with the bonus of antioxidants. But from a weight loss perspective, plain water may be more advantageous. This may explain a study that found that when overweight and obese people were randomly assigned to replace diet drinks with water, they lost significantly more weight. This is meant to eliminate all artificial sweeteners, but instead diet drinks may have been too concentrated to have the same water-induced metabolism-boosting effects. As you can see below and at 4:29 of my video, diet soda, like tea, contains approximately 10 times the concentration of dissolved substances compared to tap water. Therefore, plain water may be best on an empty stomach.
Does water temperature matter? In an academic journal published by the American Society of Mechanical Engineers, an engineering professor proposed that the “secret” of a raw food diet for weight loss is the temperature at which the food is served. “Raw foods, by their very nature, are consumed below room temperature.” To bring two cups (480 mL) of room-temperature water up to body temperature, you need to dip into your body’s fat stores and burn 6,000 calories, he says. has been calculated. Do the math, he says. A calorie is defined as the amount of energy required to raise the temperature of 1 gram of water by 1°C. In other words, 2 cups of water is about 500 grams, and the difference between room temperature and body temperature is about 12 degrees Celsius, so the required calories are about 500 x 12 = 6,000 calories.
Can you see the mistake? A “calorie” in nutrition is actually one kilocalorie, which is 1,000 times larger than the same word used in other sciences. It’s confusing, right? Even so, I was surprised that the paper was published.
In other words, drinking two cups of room-temperature water actually takes only 6 calories to warm you up, instead of 6,000 calories. Now, if you’re a hummingbird drinking cold nectar that’s four times your body weight, you could use up to 2% of your stored energy to stay warm, which doesn’t make that much of a difference to us.
So what about really cold water? A letter published in the Annals of Internal Medicine called the “Ice Diet” states that eating about 1 quart (1 liter) of ice (like a giant shaved ice without the syrup) removes 150 ml of ice from our bodies. We estimate that you may be deprived of more than just calories. “The same amount of energy as the calories you burn to run one mile.” However, it does not directly burn fat to heat water. By restricting blood flow to your skin, your body only traps more of the waste heat it would normally release. How is it done? norepinephrine.
Comparing drinking body temperature water, room temperature water, and cold water, blood flow to the skin is significantly constricted after room temperature water and cold water, as seen below and at 6:39 in my article. That’s all. video.
Additionally, as you can see here and at 6:45 in the video, neither hot nor lukewarm water can increase your metabolic rate as much as cold (refrigerator temperature) water. When we drink cold water, our bodies end up burning more calories (at least indirectly).
Therefore, drink 2 cups of cold water on an empty stomach several times a day. Is it okay anytime? Yes, watch my evidence-based weight loss lecture to see how drinking water right before a meal can add the benefit of a negative calorie preload.
Too good to be true? no. Check out three other videos about water and weight loss in the related articles below.
