Evolution is a slow and gradual process. Since the typical modern diet does not resemble the diet humans have followed for the majority of history, our metabolisms are designed to work best on a “feast or famine” schedule. Our bodies store fat when food is plentiful, and burn it off in times of scarcity. Since most Americans do not experience periods of fasting, we retain that body fat and gain weight. Because of this, intermittent fasting is a very effective way to lose weight. Not only will our bodies burn off fat stores while we fast, but fasting has also been shown to reduce inflammation in the body, speed up metabolism, reduce blood pressure, and lower risks for type 2 diabetes.
Kourtney’s not the only Kardashian who’s been a devotee to the low-carb lifestyle. Kim has jumped on the bandwagon, too, and, according to a story published in June 2016 in People, reportedly lost 60 pounds (lbs) after having her son, Saint, while on the Atkins 40 diet. Atkins 40 is a version of the Atkins diet designed for people with less than 40 lbs to lose, and has been around since the 1970s. Atkins is essentially the original keto diet and involves a very limited intake of carbs and high amounts of fat. The main difference is that on the Atkins diet you’ll slowly reintroduce carbs, so ketosis likely will only come into play during phase 1. 

It isn’t so much the metabolism slowing in my 50’s as it is the bad habits associated with youth. A box of Mac and Cheese was not a bad choice when competitive and highly active, I needed the carbs. But the mindset that a full box is a single sized serving remains despite the slow down in activity and metabolism. That’s where the real challenge lies. Too many years of eating rabbit food only after it was processed into a rabbit (or steer preferrably) with potato or corn as the only acceptable vegetable.
