Melatonin: A Metabolic Engine for Insulin Health

“How This Nighttime Hormone Influences Fat Storage”

Most of us know melatonin as the sleep hormone that keeps circadian rhythm in check. But did you know it also plays a key role in how your body handles sugar and stores fat? Your body relies on insulin hormone to move glucose from your bloodstream into cells for fuel. If your cells stop responding, it causes insulin resistance. But, melatonin is about balance as it boost insulin to lower blood sugar levels but also produces glucagon to keep levels from dipping too low at night.

While short-term melatonin use can temporarily reduce insulin secretion, animal studies suggest it can actually increase insulin levels over the long haul by helping to heal and grow insulin-producing cells in the pancreas. In fact, a recent metareview of 15 human studies found that taking a melatonin supplement had positive effects on fasting blood glucose, insulin resistance, and overall blood sugar control. Just keep in mind that the dosage and timing matter most.

Indeed melatonin acts as a powerful metabolic engine for fat storage. Fact is, it encourages your body to convert white fat, which is good at storing calories, into beige fat that actively burns energy for fuel. By shifting fat out of storage mode, melatonin helps inhibit weight gain, reduces harmful visceral fat, and fights obesity-related inflammation. So, while you might be taking melatonin for a good night's rest, it's quietly working behind the scenes to keep your metabolism running smoothly.

How melatonin hormone affects blood sugar...

Understanding how melatonin affects your blood sugar can be a bit complicated, but it largely comes down to one key factor: timing. While your body naturally produces melatonin to help regulate your sleep cycle, it can also interfere with your glucose metabolism by making you less responsive to insulin. When your melatonin levels rise, it acts on receptors in your pancreas to inhibit the release of insulin. This process is actually designed to help your body maintain its natural fasting state while you sleep. However, this means that blood sugar can spike if you eat shortly before or after taking melatonin. Studies do suggest that both your body's natural nighttime melatonin production and supplements can lead to elevated glucose levels if paired with late-night food, so it‘s best to be mindful of midnight snacking habits when using this supplement.

PROTIEN-FIRST FOODS FOR BETTER INSULIN SUPPORT

Insulin is a highly crucial hormone that helps your body absorb glucose and balances your blood sugar levels. But, as discussed above, insulin resistance that occurs when your body’s cells cannot use insulin efficiently, can cause health issues, damage to organs, and loss of critical muscle mass. Protein-first foods that can support insulin sensitivity include non-starchy vegetables, nuts and seeds, lean protein-rich meats, fish, soy, unsweetened yogurt, and tart berries that are high in antioxidants.

On the other hand, there are foods and drinks that someone with insulin resistance should avoid as they are more likely to raise blood sugar levels. This naturally includes highly processed foods with added sugar or simple carbohydrates that raise blood glucose levels. These culprits include sweetened drinks, fruit juices, soda, alcohol, cupcakes, ice cream, chocolate bars, refined grains, white bread, rice, and flour-based foods that are lower in fiber than whole grain versions. Foods high in saturated fats and salts should also be limited.

As you might guess, following a personalized menu plan that includes a variety of nutrients can improve insulin sensitivity. One of the key ways to select your menu items to manage blood sugar and reduce insulin resistance is to eat foods with a low-glycemic index. For example, dark leafy greens are a better vegetable choice than starchy vegetables like potatoes, corn or plantains. Commonly used as a staple in many cuisines, starchy veggies have 3 to 6 times more calories than non-starchy varieties like broccoli. Plus, foods are healthiest when baked, boiled or steamed, rather than fried.

Whether released naturally or taken as a supplement, melatonin can directly affect your metabolism and body composition. Studies show it can increase insulin sensitivity, decrease inflammation, and encourage “browning” of white adipose tissue to convert fat that normally stores energy into brown fat that burns it. But, timing and hormonal balance are the keys to better rest at night. If you’re struggling to sleep, contact Metabolic Research Center SW Omaha/Papillion today. One of our weight loss coaches will be in touch to discuss how you can get a good night’s sleep and still enjoy the weight loss benefits of a protein-first, low carb diet. After all, the quality of sleep you get isn’t just about getting through your daily grind; your gut-brain-melatonin axis is directly linked to increased risk of heart disease, high blood pressure, diabetes, kidney disease, stroke, and obesity.

*NOTE: Generally speaking, melatonin supplementation should be avoided by pregnant or breastfeeding women, those with autoimmune disease, or individuals taking immunosuppressants, blood thinners, or certain blood pressure medications.
