Two Trains of Thought on Water Temperature & Weight Loss
If you’re like us, you’ll be surprised to learn that there are actually two trains of thought on this topic—and they’re directly opposed to one another. The first theory states that because your body has to warm up the iced water, it has to expend calories. If you replace all 8 glasses of water with iced water, you would “burn” about 75-100 a day.
The other theory, though, says that when iced water hits your stomach it only serves to lower your core body temperature so much that your body responds by lowering its metabolic rate. In other words, instead of “burning” calories, your metabolism would actually drop.
So which theory is right? Who knows? The most recent study we could find was a 2006 study published in the Journal of Clinical Endocrinology and Metabolism. It found that room temperature water didn’t increase energy expenditure at all and refrigerated water caused only a small response but that this response was insignificant. Their findings: ultimately, water temperature doesn’t play a real role in weight loss.
