Bedtime hunger is common, especially during full throttle Spartan training. Dinner has long come and gone, and that growling stomach is becoming increasingly assertive. “Feed me, feed me,” it demands.
You resist, of course, because you’ve been programmed to believe that late-night snacking causes weight gain and sluggishness. This is pure fiction. And the happily-ever-after to this bedtime story is that pre-sleep snacking is not just okay, but beneficial—especially in the pursuit of your obstacle course racing dreams.
However, before you order delivery (or DiGiorno), here’s a caveat: Protein before bed is a great nighttime snack for athletes. This snack should be moderately portioned and eaten about an hour before sleep. Depending on your size and energy expenditures, aim for a snack with 10 to 20 grams of protein and 200 to 300 calories. Here are some guidelines and ideas.
How Protein Before Bed Helps
Encouraging muscle growth is perhaps of the biggest benefit of protein intake before nodding off. According to experts, consuming protein between dinner and bedtime can help repair, maintain, and build new tissue in muscles that have been stressed by physical activity.
It’s true that eating a protein-rich snack within one hour of intense activity helps muscles recover and grow, but there’s also a window of opportunity to tap into the power of protein while you sleep. During the deep REM sleep stage, your body sends out its biggest blast of growth hormone. Consuming protein before crashing for the night helps feed the furnace to optimize workout gains. Eating a protein-rich snack can also help to stabilize blood sugar, keep you from waking up starving, increase metabolism, and promote weight management because more muscle burns more calories.
Why Casein Is King
Not all proteins are created equal when it comes to late-night noshing. Animal proteins like beef, chicken, fish are slower to break down and get put to good use by the body, seemingly sitting in the stomach all night. This fullness can make it hard to fall asleep or stay asleep if you’re easily bothered by reflux or heartburn. Even plant proteins like beans can cause uncomfortable gastrointestinal stress.
Protein powders, especially casein protein powder, and low-fat dairy products (naturally high in casein) are great late-night snack choices. Research shows that consuming casein protein before bed is a better choice than whey and other popular picks as it’s digested and absorbed by the bloodstream at a slower rate, keeping muscles in a non-cannibalizing, anabolic state. This extended nutrient delivery is ideal for those 7 or 8 hours you are snoozing, recharging for your next day full of Spartan training.
Which Bedtime Snacks Are Best?
Try various smoothies, shakes, and “sundaes” using low-fat varieties of milk, Greek yogurt, or cottage cheese, all of which are high in casein protein. Add a handful of berries or tablespoon of nut butter for flavor. You can also try freezing smoothies in ice cube trays or pop molds for a frozen treat. Milk with granola or protein-fortified cereal is an easy fix.
If in the mood for something savory, half a sweet potato with cottage cheese is a great choice. Or, how about a mozzarella cheese stick for the simplest of snacks? Those who are lactose-intolerant can safely consume casein in a non-dairy format; just look for casein protein isolate powder on the health food aisle of your market.
Casein and lactose are two completely different parts of milk—the former being milk proteins and the latter being milk sugars. Oh, and another benefit of eating or drinking dairy for a nighttime snack: The calcium and tryptophan found in dairy work together to manufacture sleep-inducing and -regulating melatonin.
