Drink Water to Lose Weight | NutritionFacts.org

Start drinking cold water on an empty stomach to boost weight loss and encourage weight reduction. Try this strategy multiple times each day until the weight starts dropping off!
After drinking two cups (half liter) of water, your bloodstream may experience an immediate surge of the adrenal hormone noradrenaline similar to what would occur from smoking cigarettes or sipping coffee, potentially increasing metabolism by up to 30 percent within an hour as shown below and in my video Optimizing Water Intake to Lose Weight at minute 22 of my video, thus speeding weight loss up by 44 percent and making water drinking the safest, simplest, and cheapest method available to increase metabolism.

Now, this entire strategy may backfire if you’re on a beta-blocker drug (typically prescribed to treat heart conditions or high blood pressure, these tend to end with “ol” like atenolol, nadolol and propranolol; sold under Tenormin, Corgard or Inderal respectively.) As seen below and at 1:59 in my video, giving people metoprolol (sold as Lopressor) before drinking their two cups (480mL) of water effectively prevents metabolic boost. Otherwise drinking should work; what are its optimal dose, type temperature timings and timings?

One cup (240 mL) of water may be enough to boost noradrenaline nerves, yet reaping additional benefit may require two or more (480 mL). Reminder: Never consume more than three cups (710mL) in one hour as that exceeds what your kidneys can handle. If you suffer from heart or kidney failure, consuming extra water may not be recommended; but even with healthy kidneys, any more than three cups per hour could severely dilute electrolytes in your brain and potentially have detrimental consequences. (In my book How Not to Diet, I describe an emotionally draining hospital experience as an intern: when one of our patients literally drank themselves to death through water intake due to neurological thirst syndrome; while I knew enough to restrict his liquids intake and shut off his sink and toilet in time)
Back on track. What kind of water are we discussing here? Does plain, regular water have to be the focus here, or can other variations like diet drinks be just as effective at helping reduce fainting before blood donation? Actually it does matter; plain water has shown itself far superior when trying to prevent fainting prior to blood donation while juice or carbonated drinks don’t do the same job in keeping people from becoming dizzy when standing up compared with similar volumes with added salt in them – see images and video at 2:40 for examples of both options below and 2:40 in my video at 2:40! What gives here? What gives?

At first, we thought stomach distention was to blame; when eating, our body shifts blood flow toward digestion by secreting noradrenaline into our veins that pulls blood from other parts of our bodies (known as gastrovascular reflex). Therefore, drinking water was thought of as an effortless way of expanding stomach size without adding additional calories; but, ironically, when sipping two cups (480 mL) of saline solution instead (essentially salt water), any metabolic boost vanished completely and thus cannot explain this phenomenon of water effect!
Now we understand our body can detect osmolarity – the concentration of material within liquid – using hidden feeding tubes slipped into people’s stomachs with different concentration liquids, detection was demonstrated through sweat production as an indirect measurement for noradrenaline release – this may come via spinal reflex, like preserved spinal reflex in quadriplegics, or through liver receptors if their nerves had been severed – either way our bodies know and we now count 33 senses!
My Daily Dozen recommendations name certain teas as some of the healthiest drinks; after all, they offer all the hydration benefits of water while offering antioxidant support as an added perk. But from an overall weight-loss standpoint, plain water may provide greater advantages. Studies involving overweight and obese participants who swapped out diet beverages for water lost significantly more weight. This change may have been attributable to cutting down on artificial sweeteners; however, it could just as likely been related to my drinking less diet drinks that contained too much concentrated dissolved substances than could offer similar metabolic support as drinking tap water directly would do. I could see at 4:29 of my video that diet soda (like tea!) contained about 10x the concentration of dissolved substances than tap water did and so drinking just plain water on an empty stomach may offer greater metabolic advantage than diet drinks or tea could.

Does water temperature really make a difference for weight loss? According to research presented at an American Society of Mechanical Engineers journal meeting, an engineering professor noted that an important element in any raw food diet for weight loss might lie within its serving temperature. Raw foods should generally be consumed at room temperature or lower. In order to bring two cups (480 mL) of room-temperature water closer to body temperature, Dr. Li estimated that our bodies would have to use up 6,000 calories from stored fat reserves.” “Do the math,” advises Mr. Wood: A calorie is defined as the energy required to raise one gram of water by one degree Celsius; since two cups of water weigh roughly 500 grams each and there’s typically an approximately 12-degree temperature difference between room temp and body temps, that amounts to 500×12= 6,000 required calories for increasing temperature change by one degree Celsius.
Do you see where I made a mistake here? Nutrition uses “kilocalorie” rather than the more familiar “calorie”, making this paper even more confusing to understand than before it was published! I was honestly taken aback that they managed to publish such an error-filled piece!
So drinking two cups of room temperature water takes only 6 calories to warm up instead of the more commonly perceived number of 6. If we were birds sipping nectar four times their weight in temperature-sensitive nectar instead, up to two percent of their energy reserves could be expended warming it up in doing this process; but for humans it won’t make such an impactful difference in warming it up!
So how about really cold water? A letter published in Annals of Internal Medicine called the Ice Diet estimated that eating one quart (1 L), like eating an enormous snow cone with no syrup on it, could sap our bodies of over 150 calories–equivalent to burning an equal number while running one mile. Your body doesn’t directly burn fat to warm the water either–instead, your blood flow to skin becomes restricted which releases waste heat that leads to greater noradrenaline release from within your system and off your body–reincorpusin keeps more waste heat out from leaving our bodies than it normally gives off; your body simply corrals more waste heat off by constricting blood flow to skin thereby controlling waste heat production from within yourself–all thanks to noradrenaline!
Comparing body-temperature water, room-temperature water and cold water for drinking purposes only shows significant restriction to skin blood flow in room-temperature and cold water environments, as can be seen below and at 6:39 in my video.

As demonstrated at 6:45 in the video, neither warm or tepid water could increase metabolic rate as much as drinking fridge temperature water does, leading us to burn off more calories indirectly through metabolism.

Does drinking two cups of cold water on an empty stomach several times daily matter for weight loss? Absolutely; my Evidence-Based Weight Loss lecture can show you the power of negative-calorie preloading by drinking that water shortly before meals.
Too good to be true? Nope – check out my other videos about water and weight loss below in related posts! if(f.fbq=function()n.callMethod??>
