Calories are NOT created equally! Quality matters. 100 calories of a sugary holiday beverage will affect your body much differently than 100 calories of roast turkey. In fact, as healthy and appealing as good protein is, we're hardwired to prioritize calorically dense sweets as a way to survive times of famine, with bodies that are well adapted to quickly store the sugary/starchy stuff as fat for the future. Most animals are the same, from fruit flies to us humans . Think of bears fattening up on honey and blueberries before hibernation, or birds eating fruit before migrating long distances. Craving sweets is a built-in plan to save us during times of scarcity but instead, it's become quotidian, part of the Standard American Diet. How many desserts/cookies/treats have you been offered since Halloween? Think of how many more you'll be offered from now until New Year's Day–not to mention, all of the sugar that's been added to things like your jarred pasta sauces, yogurt, and prepared convenience foods!!
