Critically Speaking

May 12, 2021

Obesity and its accompanying health problems clearly are associated with overeating, especially of high sugar and fatty foods, and a sedentary lifestyle. But it turns out that while we need to be careful with respect to what we eat, when during our waking hours we are eating also has a significant effect on weight gain and general health. The same amount and types of calories can have vastly different health effects depending upon when they are consumed. The light-dark cycle influences our sleep wake circadian rhythm, but the time of day we eat controls another metabolic circadian rhythm. Today we talk with a discoverer of this eating-mediated circadian rhythm, Dr. Satchin Panda of the Salk Institute in La Jolla. Dr. Panda has laid this system out for us in his book, “The Circadian Code : Lose Weight, Supercharge Your Energy, and Transform Your Health from Morning to Midnight.”


 Key Takeaways:

  • The same amount of calories consumed throughout the day leads to more weight gain that does eating them meals within a 10 hour time frame. 
  • This is called time restricted eating or TRE.
  • In addition, a number of health indicators are better with TRE, leading to reduced risk for diabetes, heart disease and stroke.
  • Consuming ice cream before bed, or raiding the refrigerator in the middle of the night, are among the worst practices. Better to have the ice cream earlier in the day.


"The field of nutrition science, over the last 100 years, has verified and validated that the quality and quantity of nutrition are extremely important for health. And now this new concept also tells us that the timing of food is equally, or even more, important." —  Dr. Satchin Panda
