The first gulps of water I’ve after a future are scrumptious. They’re refreshing and life-giving, sure, however the water additionally tastes good. It really tastes candy, to be extra exact.
Which, once I stopped to consider it mid-gulp sooner or later, I discovered odd. Isn’t water a famously, um, impartial taste? And why does it style totally different after one among my lengthy runs?
I’m not imagining issues: A systematic review of literature on the connection between style and train discovered that candy style depth and sensitivity will increase after acute train. Nonetheless, Jason Machowsky, an train physiologist and registered dietitian on the Hospital for Special Surgery in New York Metropolis, says why that’s really taking place isn’t so clear.
“There doesn’t appear to be any well-researched causes for it,” Machowsky says. “There are, nonetheless, a whole lot of theories.”
The primary speculation has to do with the concept of “heightened sensitivity.” Machowsky explains that there are minerals in water that do style candy to some folks, and so after a strenuous exercise, these minerals may style much more noticeably sweeter.
In a associated (however semi-gross) clarification, your post-workout water could possibly be dredging up previous meals particles or residue in your mouth that you simply’re re-tasting in a extra dramatic approach, because of that sensitivity.
Or one thing else could possibly be occurring fully. You might have heard of “ketosis,” the metabolic state during which the physique burns fats as an alternative of carbohydrates (attaining ketosis is the intention of the keto diet). This state happens when glycogen shops (which come from carbohydrates) are depleted, so the physique turns to fats for power. What, moreover the keto weight-reduction plan, may cause somebody to run via their glycogen shops and use fats as an alternative? Intense, extended train.
Being in ketosis can have some bodily manifestations, together with—watch for it—candy breath.
“A ‘candy’ taste or aroma to [the] breath is a byproduct of the breakdown of ketones for power,” says Machowsky. So ingesting water and noticing a candy taste may come from the interplay of water and your individual breath. Nonetheless, Machowsky notes that this may solely come about if somebody is adhering to a strict ketogenic weight-reduction plan, or if they’ve executed “sustained exercise to considerably deplete your glycogen reserves.” So not simply any previous exercise would trigger this—you’d possible should be doing cardio train for about an hour and 45 minutes earlier than hitting this level.
The ketogenic state leading to candy breath isn’t one thing it is best to essentially aspire to. Specifically, for folks with diabetes, a candy style or candy breath could be a warning signal that their glycogen shops are low.
“Those that have diabetes who train when their blood sugar isn’t nicely regulated or too excessive (>250 mg/dL) could expertise ketone manufacturing, indicating their physique isn’t correctly utilizing the glucose of their physique for power and could also be resorting to ketones as power,” Machowsky says. “Intense train can typically exacerbate that situation.”
That’s why Machowsky advises that “in case you are diabetic and your blood sugar is just too excessive, it could be finest to do low depth exercise (like strolling) or get your blood sugar again right into a safer vary earlier than beginning excessive depth train.”
It doesn’t matter what your post-workout water tastes like, you must agree that the best way our our bodies gas our motion is fairly miraculous. So be sure to’re giving your self proper nutrition and plenty of rest in between exercises so you possibly can maintain residing that candy life.
