Reset Your Internal Clock to Restore Rhythm

“The Role of Melatonin in Managing Food Cravings and Metabolism”

Routinely resetting your internal clock helps avoid chronic health issues like poor digestive processes, hormonal imbalances, and impaired healing or recovery. Managed by your brain’s suprachiasmatic nucleus, the process of re-syncing your 24-hour biological clock with your environment can be challenging, but restoring this important rhythm is key to regulating your personal sleep-wake cycles. Once your rhythm is disrupted, it can take several days to a few weeks to succeed.

However, melatonin hormone does much more than just signal your body that it is time to sleep; it lowers your core body temperature (thermogenesis) and manages key metabolic activity while you sleep. As the master regulator of your body’s circadian rhythm, it flips your sleep-wake switch for you to prepare your body for rest, as natural and manual changes in light will trigger melatonin production to reduce alertness, energy, and wakefulness.

If you want to keep your circadian rhythm functioning properly, there are a few simple habits you can adopt. Start by maximizing your exposure to morning sunlight early on after waking up. In early evenings, avoid blue light from screens and stick to a strict, consistent sleep schedule each night, including weekends. Nonetheless, eating when melatonin levels are high, forces your body to digest food, impairs your body’s glucose tolerance, and increases cravings at night.

Melatonin’s impact on fat browning...

Disruptions to your circadian rhythm via shift work, jet lag or late-night snacking are linked to obesity, type 2 diabetes, and cardiovascular issues. Here’s where melatonin plays a surprising role in how your body processes fat and sugar. It actively helps convert standard white fat into metabolically active beige fat. This process, known as "browning," has a major impact on your energy balance and calorie expenditure. The effect of the darkness hormone on adipose tissue is significant, as it involves the conversion of white adipose tissue to metabolically active beige fat that burns calories to generate heat when activated by cold exposure or stress (cortisol). This conversion has a significant impact on energy homeostasis, including energy expenditure, metabolic balance, visceral fat storage, and unintended weight gain.

PROTEIN FIRST MENUS CAN BOOST SLEEP QUALITY

Did you know that the protein on your plate plays a direct role in how well you sleep? Healthy protein sources are packed with tryptophan. Your body uses this essential amino acid to create serotonin, the hormone that helps regulate your mood, appetite, and pain levels during the day. When the sun goes down and darkness sets in, your pineal gland converts that serotonin into melatonin—the crucial hormone responsible for managing your body's sleep-wake cycles. But, poor dietary habits can easily disrupt this delicate hormonal balance.

Consuming high-sugar foods, citrus fruits, and caffeinated beverages like coffee or energy drinks can hinder your natural melatonin production. Even alcohol is deceptive; while a nightcap might help you nod off initially, it ultimately disrupts your long-term sleep quality. By incorporating melatonin or tryptophan-rich foods or supplements into your routine, you can increase your sleep duration, reduce inflammation, and boost your body's glutathione levels. In fact, a drop in melatonin is often the hidden root cause behind many common sleep disorders.

So, what should you be eating to support better sleep? Depending on your specific nutritional needs, animal proteins are often a great choice because they are complete and easily digestible. While turkey is famous for making people sleepy, chicken breast actually provides even more of the tryptophan needed to synthesize these essential sleep neurotransmitters. If you follow a plant-based or restricted diet, there are still plenty of excellent options available. You can easily get your daily dose from tuna, soy, casein protein from milk, eggs, cheese, low-glycemic vegetables, and a variety of nuts and seeds.

Melatonin is often called the hormone of darkness and, as a master biological signal that synchronizes your internal clock with your external world, tells your body when it is time to rest. But beyond just inducing sleep, it serves as a critical link between your light-dark cycles, metabolic efficiency, and appetite control. Not a sedative, melatonin is the primary time-giver used by your brain’s master clock to regulate circadian rhythm.

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.
