Hi, my name is Dr. Keegan Duchicela I’m the medical director of the Health Nucleus in San Diego California, and let's talk about why late-night eating is so bad for you. We've all done it. It’s 10:00p.m. you're exhausted after a long day, and you can't wait to sit on the couch and dig into some ice cream it tastes so good but you know deep down is probably not the best for you. We all know that highly processed foods and refined sugars will spike your blood glucose levels and while what you eat matters when you eat could be just as important. Our metabolism actually changes throughout the day. If you give somebody the exact same meal for breakfast lunch and dinner, you'd expect your blood sugar spikes to be similar, but they're not the lowest blood sugar spike is in the morning and the highest is in the evening, again for the exact same meal and quantity of food. So, what's going on at nighttime? It could be melatonin. In the evening about two to three hours before our bedtime our pineal gland secretes melatonin. Melatonin binds to receptors on the pancreas telling the pancreas to stop secreting insulin. It essentially tells the pancreas to go to sleep if there's no insulin your blood sugar stays high. This has implications not just for people with diabetes but for all of you with just borderline elevated sugars.
One study showed that people with high normal and borderline fasting blood glucose levels were associated with lower hippocampal volumes the structures in the brain that are involved in cognition and memory, and we know that hippocampal atrophy or shrinking of this tissue is associated with certain neurodegenerative diseases like Alzheimer's dementia. Just a quick note here genetics plays a role as well there's a variant of the MTNR1B gene that about a third of the population has that makes pancreatic cells more sensitive to the effects of melatonin, resulting in less insulin secretion in a higher blood sugar spike. Knowing you have this variant could make it even more vigilant about avoiding those late-night snacks. So, let's recap, why is it so awful to eat late at night? Well hours before you go to bed your brain releases melatonin, which tells your pancreas to stop releasing insulin. That sugar in your bloodstream from the ice cream stays elevated which over time is associated with hippocampal atrophy and a higher risk of Alzheimer's.
“we make very poor decisions with our late-night food selections”
So, my recommendation, try to have your last food intake at least a few hours before you go to bed and before that natural increase in melatonin. And let's be honest we make very poor decisions with our late-night food selections anyways, no one's on the couch watching their favorite TV show with a big bowl of salad at 10:00 p.m. it just doesn't happen. All right, so I hope you enjoyed this segment on why you should avoid late-night eating references and links to some really good studies are down below, and I encourage you to subscribe if you're interested in learning more about precision medicine and optimizing your health.I'm Dr. Keegan Duchicela. Take care and be well.

Answers:
Part 1: Comprehension
This video was created by the YouTube channel called Human Longevity. They made it to raise awareness of the dangers of eating late at night. Dr. Duchicela starts the video by introducing himself as a doctor based in San Diego and states that he is the medical director of the Health Nucleus. He then talks about the fact that while highly processed foods and refined sugar, will spike your blood glucose levels when we eat food can be just as important. The lowest blood sugar level spike is in the morning and the highest is in the evening, so Dr. Duchicela proposes that it’s a health risk for people to eat late in the evenings. Some health risks include diabetes and Alzheimer’s, and he recommends having your last food intake at least a few hours before you go to bed, and before the increase in natural melatonin.
Part 2: True or False
A: True B: False C: True D: False

Part 7: Writing (example)
Maintaining a healthy lifestyle is very important to me. I start my day with a morning routine of stretching exercises and a short meditation to clear my mind. For my diet, I focus on balanced meals with plenty of vegetables, fish, and rice, which is typical in Japanese cuisine. I also make sure to stay hydrated by drinking green tea and water throughout the day. Additionally, I enjoy regular outdoor activities like walking or cycling, especially in the serene local parks, to stay physically active. Mental health is equally important, so I often practice mindfulness and occasionally enjoy Onsen (hot spring) visits for relaxation. Lastly, I make it a point to get enough sleep each night, as it's crucial for overall health and well-being.
