A health-wrecking nutritional practice that subtly destroys health goals is that of eating very dense, ultra-processed, salty, and or sweet foods after 5 pm. This is primarily because human bodies are meant to metabolically manage and optimally digest their energy sources during the daytime hours. Once the sun sets, digestive organs begin to wind down and essentially shut down because the body enters a mode of recovery. Here are 8 reasons to stop consuming heavy foods after 5 pm for optimal health, longevity, and sleep:
The Circadian Decline of Insulin Sensitivity
As our insulin sensitivity is inherently highest in the morning and lowest towards the end of the day, we are more likely to suffer from postprandial hyperglycemia (after-meal blood glucose levels) and develop insulin resistance if we consume sweet and carbohydrate-rich foods after 5 pm.
Inhibition of HGH Secretion
Growth hormone, crucial for muscle repair, burning fat, and cellular repair and regeneration, is only released in peaks during the first full sleep cycle of the night. Consuming food at late hours with consequently increased insulin levels will inevitably suppress this anti-aging hormone.
Blocking Melatonin Production
Digestion is an energy-intensive process that leads to elevated body temperature. For your pineal gland to efficiently secrete melatonin (the signaling hormone for sleep), your core body temperature needs to be lowered significantly. Eating at late hours delays this necessary thermal drop, negatively affecting sleep patterns.
Stalled Migrating Motor Complex
The migrating motor complex is the body’s automatic housecleaning mechanism for the digestive system, which is activated when fasting. Eating at late hours will interrupt this critical sweeping function in the GI tract and keep undigested food particles and bacteria stagnant in the small intestines for extended periods, often leading to gas and bloating.
Enhanced Systemic Inflammation
Late-night meals composed of nutrient-poor, high-sodium, refined sugars, and inflammatory fats prompt a sustained inflammatory response. The absence of daytime activity to manage this process effectively leads to increased low-grade systemic inflammation during your body’s critical repair cycle at night.
Compromised Liver Detoxification
Your liver operates according to its own circadian clock, and at nighttime, it is in its metabolic and detoxification state. If we continuously drip fresh macronutrients into your body during this very important time of liver detoxification, we will cause congestion of the liver and completely disrupt the processes involved in detoxification, along with the cholesterol production process.
Fragments REM and Deep Sleep
Because your body and gut are working so hard together to digest a substantial meal, you are unable to progress into the deeper stages of sleep. Sleep is interrupted, causing you to wake up in the morning feeling groggy and unfocused, even if your body is technically resting.
The Silent Trap of Nocturnal Sodium Retention
So many pre-packaged evening meals and snacks are incredibly high in sodium, but you will likely not feel the effects of this late at night. Since the body naturally slows the circulation of fluids while sleeping, sodium consumed after 5 pm will promote the retention of water in the body, contributing to morning swelling and joint congestion.
