The theory behind intermittent fasting is that our early ancestors ate with fasting cycles, and that our shift into eating three meals a day goes against our natural instincts and needs. A look at this backstory gives insight into when intermittent fasting might be helpful.<\/p>\n\n\n\n

Intermittent Fasting Returns Us to Our Natural Way of Eating<\/h2>\n\n\n\n

In Fast This Way<\/em><\/a>, Dave Asprey explains the theory behind intermittent fasting. He writes that <\/strong>our modern eating habits differ dramatically from our ancestors\u2019. <\/strong>Most of us believe we need food more than we really do, and thus we eat three meals a day\u2014or more. Asprey argues that this pattern of eating isn\u2019t driven by our natural needs but instead is a product of the Industrial Revolution<\/a>, when people adjusted their eating habits to fit factory and train schedules.<\/p>\n\n\n\n

(Shortform note: The American norm of eating three meals a day may date back further than Asprey suggests, with some experts tracing it back to the colonization of America by European settlers<\/a>. The Native Americans had a flexible and seasonal approach to eating, which the Europeans saw as \u201cuncivilized\u201d and inferior. So, to distinguish themselves as more cultured and civilized, the Europeans adopted a more rigid eating schedule that the Industrial Revolution\u2014and the lifestyle changes it brought about\u2014later reinforced. Thus, experts argue that this meal regimen not only has little basis in our body\u2019s metabolic needs but may also have emerged as a result of racial prejudice.)<\/p>\n\n\n\n

Asprey argues that by intermittent fasting (alternating between specific windows of eating and not eating), you can eat according to your body\u2019s true needs<\/strong>\u2014you\u2019re biologically programmed to get energy from food and then allow your body to rest and heal. Our ancestors used to eat in this way as they regularly cycled between feast and famine depending on the availability of food.<\/p>\n\n\n\n

(Shortform note: Some experts argue that just because our ancestors ate in a certain way, it doesn\u2019t mean it\u2019s good or healthy for us today<\/a>. They point out that people had much shorter lifespans back then and often suffered from nutrient deficiencies. They also counter the assumption that our bodies haven\u2019t evolved to handle modern food, arguing that evolution occurs quicker than we often think. Because of this, they question whether we (who live longer and have more control over our eating) would benefit from adopting our ancestors\u2019 diet. In other words, while fasting may have its benefits, it\u2019s not necessarily because it mirrors our ancestors\u2019 lifestyles.)<\/p>\n","protected":false},"excerpt":{"rendered":"
