I have found Dr Panda’s work and this book fascinating and helpful and would therefore invite you to explore more of his work if this short summary has sparked your interest.

These cells contain the photopigment melanopsin and their signals follow a pathway called the retinohypothalamic tract, leading to the SCN. If cells from the SCN are removed and cultured, they maintain their own rhythm in the absence of external cues. [81] Chellappa SL, Morris CJ, Scheer FA (January 2019). "Effects of circadian misalignment on cognition in chronic shift workers". Scientific Reports. 9 (1): 699. Bibcode: 2019NatSR...9..699C. doi: 10.1038/s41598-018-36762-w. PMC 6346005. PMID 30679522. Excellent book for information on the circadium rhythms of the bodies organs, brain, and how this effects how we digest foods, insulin spikes, hormonal weight gains and quality of sleep. As others pointed out the strength of this book was all in regards to Dr. Panda's timing research and how this directly impacts how much food effects us biochemically, and the downstream effects in regards to mood/energy/sleep. The SCN takes the information on the lengths of the day and night from the retina, interprets it, and passes it on to the pineal gland, a tiny structure shaped like a pine cone and located on the epithalamus. In response, the pineal secretes the hormone melatonin. [82] Secretion of melatonin peaks at night and ebbs during the day and its presence provides information about night-length.

The observation of a circadian or diurnal process in humans is mentioned in Chinese medical texts dated to around the 13th century, including the Noon and Midnight Manual and the Mnemonic Rhyme to Aid in the Selection of Acu-points According to the Diurnal Cycle, the Day of the Month and the Season of the Year. [7] Initially aim for an eating window of 12 hours, and work towards an optimal 8 hour window if manageable. Settle on what works best for you and your body.

Norwegian researchers at the University of Tromsø have shown that some Arctic animals (e.g., ptarmigan, reindeer) show circadian rhythms only in the parts of the year that have daily sunrises and sunsets. In one study of reindeer, animals at 70 degrees North showed circadian rhythms in the autumn, winter and spring, but not in the summer. Reindeer on Svalbard at 78 degrees North showed such rhythms only in autumn and spring. The researchers suspect that other Arctic animals as well may not show circadian rhythms in the constant light of summer and the constant dark of winter. [53] One was about melatonin supplementation. While supplementation is not required, it can be incredibly useful for people struggling with sleep. The author covers this but then mentions a dose between 1mg and 5mg. This is way too high. For most people, this will have unwanted side-effects, such as waking up in the middle of the night or still feeling groggy the next morning. The correct dose for most people is 0.3mg (Alexander, 2018). If we average out the dose the author mentioned, he was off by a factor of 8. In his defense, such a dose is widespread, and most supplements have that dose, but it is incorrect nevertheless, and he should have known better. Supposedly a high-protein intake is not good for your health, and more specifically harmful for your kidneys. Surprise surprise, it has been researched, this is bonkers. (Phillips, 2016; Juraschek, 2013; Antonio, 2018). If you have healthy kidneys to begin with, high-protein diets are safe and healthy.
