Soda should pretty much be avoided at all times, but especially after a workout. “Soda is straight sugar,” says Foodtrainers nutritionist and registered dietitian Carolyn Brown. Just one can of soda has the equivalent of 10 packets of sugar, according Aronson. Fruit drinks are also very high in sugar. Your body needs a gradual, steady recovery from its workout but consuming so much sugar does just the opposite. If you usually crave something other than water after you work out, Aronson suggests having iced herbal tea on hand. “Either have it ready in advance (just make fruit tea and refrigerate) or buy iced tea bags (Celestial Seasonings makes iced fruit tea bags where you just add cold water and steep).” Pass on the diet soda as well. "After exercising, you want to replenish and refuel your body, even if weight loss is your goal," Brown says. "So consuming something made of artificial ingredients and chemicals is not the answer -- water and electrolytes are." If you’re not keen on water, she suggests coconut water or EBOOST -- both are healthy and all natural.
