  • It goes without saying that the diet of early humans was very different from your current ones.

  • Having to hunt and gather their food meant they ate what they could when they could.

  • Which sometimes resulted in long periods without much toeat.

  • Pizza bagels were much bigger back then, but also more vicious!

  • While I imagine they would be thrilled to live in today's world with tons of readily available foodfor most people, there may be some health benefits to restricting the time you spend eating.

  • Let's dive into that more, shall we?

  • Hey there! Welcome to Life Noggin!

  • I'm not talking about extended fastingwhen you don't eat for multiple days attime and then… I don't know, go spearfishing?

  • Maybe that's only if you're Chris Hemsworth.

  • This video is about fasting for short periods of timealso known as intermittent fasting, and it can be done in a few different ways.

  • In time-restricted eating (TRE), you eat during a set window of time.

  • common example is when you eat for 8 hours during the day and fast for the remaining 16.

  • There's also alternate day fasting (ADF), where you have days of eating and days of fasting.  

  • For instance, in the 5:2 method, you have two nonconsecutive days of fasting each week.  

  • These could include a 500-600 calorie mealor just drinks like water, tea, and coffee.

  • In both cases, you go many hours without eating.  

  • This causes a lot of changes within your body, like its energy source.

  • After 10-16 hours, the energy provided from your food will run out and your body will start to break down its fat stores.

  • Which is why most people think of intermittent fasting as a diet.

  • However, while researchers have found that it's just as effective for losing weight as restricting your calories, it can do much more.

  • In your liver, fat is turned into ketone bodieswhich control the activity of many proteins and molecules that influence health and aging.

  • Researchers have also found that cells not only adapt but are improved by intermittent fastingwith increased antioxidant defensesDNA repair, protein quality controland autophagy - the process of breaking down and recycling old or damaged cells.

  • In addition to weight loss, studies in humans have found that intermittent fasting can improve insulin resistance, cholesterol levels, blood pressure, and inflammationall of which lead to better health.

  • And animal studies have shown that it can improve physical endurance and coordination, as well as cognitive abilities like memory and learning.

  • But it's really important to note that intermittent fasting isn't for everyone and can be super dangerous if you're under 18, have certain health conditions, are pregnant or breastfeedingor have a history of eating disorders.

  • So, before you try any of these methods, you should talk to your physician.

  • This really isn't something you try without consulting a professional.

  • If your doctor does give you the green lightthey'll probably recommend you start with less restrictive methods before trying to go a full day or more without eating.

  • For the first monthyou may feel hungry, nauseous, irritable, or have difficulty concentrating as your body adjusts.

  • But if you're interested in trying it out or want to learn more, check out the work by one of the pioneers of intermittent fasting, Valter Longo, a member of the Lifespan advisory board.
