Molly Knudsen, a Registered Dietitian with roots in Texas and a master’s from Tufts, has a point we usually miss. We obsess over sleep hygiene. Chill the room. Ditch the screens. Build a routine. It’s fine. But you are ignoring the elephant in the bedroom. Or rather. The plate on your table.
Research keeps saying it. What you eat—and when—dictates your slumber.
Protein matters more than you think
Most Americans are starving their brains for sleep by skimping on protein. The average diet hits 16 percent calories from protein. That is low. Linked directly to poor sleep.
You want depth in your sleep? Aim higher. Get at least 30 grams per meal. Some folks need 50. Protein slows digestion. It keeps you steady. Eat that steak two or three hours before you lie down. Don’t scarf it down at 10 p.m. and wonder why your night is fitful. Discomfort isn’t conducive to dreams.
Fiber is the quiet helper
Here is a grim statistic. 95 percent of Americans fail to meet fiber goals. The recommendation sits between 25 and 38 grams. We average 16.
Low fiber equals lighter sleep. Less restoration.
Fiber stabilizes blood sugar. It feeds the gut. And your gut talks to your brain. A 2023 study broke this down. Fiber metabolism in the colon triggers reactions that improve the gut barrier. It calms inflammatory pathways. It boosts serotonin. Which becomes melatonin. Which makes you sleepy.
Eat beans. Eat grains. Eat fruits and veggies. If you aren’t already. Start today.
Magnesium works if you take the right kind
Magnesium gets the hype for a reason. It’s in over 300 bodily processes. Including muscle function. And energy. But for sleep. It’s the calm anchor.
It activates GABA receptors. That’s the neurotransmitter that says chill.
The trick is the form. Magnesium bisglycinate absorbs well. It’s gentle on the stomach. This is the stuff behind mindbodygreen’s sleep support+. They pair it with jujube seed extract and PharmaGABA®. Jujube has a history in traditional medicine for sleep issues. PharmaGABA is clinically shown to help you sleep soundly.
Take it one to two hours before bed. Let it do its work.
“I’ve always had difficulty with falling and sticking around asleep… This sleep support really works and keeps the sleep going all night.”

Sugar ruins the rhythm
Sneaking that ice cream? It’s a trap. Sugary snacks spike your blood sugar. Suddenly you have energy. Your body gets confused. The signal to slow down gets buried under a sugar high.
Then comes the crash. Your body pumps cortisol to save you. Cortisol wakes you up. At night. That’s backwards. Circadian rhythms want low cortisol when the moon is out.
Swap the cookie for something else. Try the no-sugar truffles mentioned earlier. Or a sleep-friendly smoothie. Your midnight self will thank you.
Water is heavy. Literally
Waking up to pee destroys sleep continuity. We know this. But we drink anyway. Right before bed.
Urologist Vannita Chiang, M.D., puts a number on it. Stop drinking three to four hours before bed. That means no giant glasses right as you hit the sheets. Spread your intake out during the day. If you have more than 8 ounces right before lying down, expect a trip to the bathroom later.
Not ideal for sound sleep.
The wrap
It isn’t just about dark rooms. It’s about what you feed that system. Eat the right protein. Load the fiber. Skip the sugar late at night. Time the magnesium. Respect the bladder.
If you are pregnant. Or on meds. Check with a doctor first. Supplements aren’t candy.
Otherwise. Just start. Maybe tomorrow. Maybe tonight.
