The StoWicks Conversations

Carolyn and Seth Wicks
Seth: There's a funny scene in The Office where Michael decides that in order to win a 5K, he needs to eat a massive bowl of fettuccine Alfredo right before the race. As you can probably guess, he looks and feels like death half an hour later. We all know that eating that many carbs right before physical exercise is a recipe for disaster. Timing matters.
We've done a few newsletters about protein, fiber, and what you should eat, but what about when you should eat? Our bodies don't run the same at 6 AM as they do at 10 PM. Insulin sensitivity, digestion, and your circadian rhythm all run on a clock, and the clock will determine how your body handles its next meal.
So instead of a food list, let's figure out what your body needs throughout the day (hint: stop eating 2 minutes before sleeping).
Carolyn: Picture this: your body hasn't had food or water in 7-9 hours. You wake up dehydrated, and your cortisol, the hormone that's supposed to spike in the morning to make you alert, is already doing its job. That's a good thing. It's your body's natural wake-up call. The problem is that most of us bombard that natural alertness with a coffee and a sugar spike before we've had anything else. Now you've got cortisol and caffeine and a blood sugar rollercoaster all firing at once, and your body is in chaos.
So what does it actually want? Water first, you're already behind on hydration when you wake up. Then protein, fat, and something with real nutrients (eggs, avocado, berries) not cereal, not a granola bar, not "coffee counts as breakfast." Real food gives your body something to actually build energy from.
Seth: Insulin sensitivity is highest earlier in the day and tapers as the hours go on. That means the same meal is metabolized more efficiently at noon than it would be at midnight, as your cells are simply more responsive to insulin's signal to gobble up glucose.
Movement adds a second, independent pathway. Muscle contraction pulls glucose out of the bloodstream on its own, which is why a 10-minute walk after lunch or even just standing and stretching at your desk does real metabolic work. It helps lower the post-meal glucose spike whether or not insulin is fully cooperating. Studies on post-meal walking have shown meaningful reductions in blood sugar spikes from a walk as short as 10-15 minutes.
During the day, pair your meals with movement while your body's insulin sensitivity is already working in your favor.
Carolyn: I've been saying this for years, but it's so much better to day-drink than drink late at night. (Because then you get to bed on time!) Not that you should go out and day drink, but my logic actually makes sense: your insulin sensitivity is winding down for the day, right as most of us are getting ready to go out and party. So that 9pm glass of wine and bowl of pasta doesn't get the same efficient handling the noon version would, it just sits in your bloodstream longer, doing less. And evening is exactly when the average person will do their heaviest damage: the biggest meal, alcohol, zero movement, whether that's the couch after dinner or happy hour with friends after work.
So what should you do? Go lighter. Notice that I'm not telling you to skip dinner, but to just get a smaller portion, less alcohol (it messes with both blood sugar and the sleep you're trying to protect), and putting the phone down way earlier than you think you need to. Your body's already telling you it's time to downshift. Evening is not the time to eat your heaviest meal or flood your eyes with overstimulating content. Focus on calming your nervous system and keeping the lights low.
Seth: Digestion and deep sleep are competing for your blood flow, energy, your nervous system's attention. Go to bed with a full stomach and your body has to choose: help you digest, or help you get deep, restorative sleep. It can't fully do both, and your sleep cycles will pay the price. That means less time in the deep stages that matter most for recovery.
Remember the insulin sensitivity curve from earlier? It's highest in the day, and declines as the hours pass? Poor sleep does leave you tired, but it also blunts that curve further, making you less insulin sensitive the next day, before you've eaten a single bite. A bad night's sleep tonight sets up a harder day for your glucose regulation tomorrow, which makes the next evening's wind-down that much harder to get right. Morning, day, evening, night - they're all a part of the same system, and each part sets up the next.
Carolyn: If it's not obvious, by the 89th newsletter we have sent, yes, we want you to eat healthy. But we also want you to realize when you eat matters just as much, relative to what your body's already doing. I'm all for a bowl of pasta and a glass of wine, just not at 10pm. And if 10pm pasta is your thing, live your life, we just want you to be aware of the trade-off you're making.
That's really the whole point of this newsletter: morning wants fuel, not caffeine, the day wants movement, and the evening wants to downshift. Remember, you're a clock, running all day, and every meal either works with it or against it. Seth and I are always looking for small ways to work with our biology instead of against it (hello weightlifting!) and if timing my meals a little differently means I sleep better, I'm less bloated, and my digestion's happier, that's an insanely easy decision. I feel better, I sleep better, and I probably look better. Who wouldn't want that?
Seth: One last note: research suggests it's large meals at night that cause the most problems. So if dinner's going to be your biggest meal, try moving it earlier and splitting it up.
Carolyn: Tell us your worst meal-timing habit: 10pm pasta, dinner at your desk, coffee before water. We'll read every reply and pretend we're not judging.
