Not eating between meals has always been a good practice.
But this article is a good reason to limit your feeding time and increase your fasting time.
As my favorite Optimal Ketogenic Living guy, Raymund Edwards, says: “Feed well and Fast well!” In the linked article, P.D. Mangan documents the benefits of complete fasting for 16-18 hours daily between meals: “It reduces inflammation and oxidative stress, leads to increased numbers and quality of mitochondria, and increases autophagy, the cellular self-cleansing process.” Fasting also Lowers insulin and promotes more fat burning. Yay for that!
Per Ted Naiman(1), there is a sweet spot between 16-18 hours for insulin reduction from fasting. Most people only fast for the 6 hours they sleep at night, if that. I have done both intermittant fasting and longer (up to 5 day) fasts. Fasting is both rejuvenating and healthy. Worth doing if you want to live a healthier lifestyle.
To really step it up, couple intermittent fasting with a very-low carb ketogenic diet and you will live in the optimal insulin state, the blue band in the chart above. Something we all should do, in my opinion. Recent science is proving this idea to be correct.
