What good does sugar fasting for 14 days actually do?
You might want to cut sugar off for two weeks
Sugar sneaks into anyone’s daily food intake in various ways: Drinks, fruit yogurt, cereal, cocktails, dressings, and more. Depending on the amount one consumes, added sugar has effects on the body that influence appetite, digestion, sleep, liver fats, insulin resistance, and energy levels.
Removing added sugar from any daily diet however, can be more than rewarding, says Harvard trained Dr. Saurabh Sethi.
What happens when you remove added sugar for 14 days?
According to Dr. Sethi, once you remove added sugar from your diet for two weeks, the brain goes through a recalibration process. Along the way, side effects including headache, fatigue, brain fog etc. can be observed. However, in the end, these fade away and a recalibrated system commences in the body. Stabilized energy levels, less bloating, better insulin response, higher sleep quality, and less sugar and food urges to fill the unnecessary craving.
It can be considered a metabolism reset rather than an extreme diet program like keto. Cutting added sugar is a minor modification with high reward to achieve a healthier diet Dr. Sathi implies.
