Fasting may have a wide range of positive effects on the body. It can improve mental acuity and concentration. It can also improve blood sugar levels and cholesterol levels. There are two types of fasting: intermittent and periodic fasting. Intermittent fasting involves a single full day of fasting once or twice per week. Periodic fasting, on the other hand, involves a few days of fasting in a row.
It May Improve Mental Acuity and Concentration
According to science, intermittent fasting may boost mental acuity and concentration. It is a time-restricted eating regime wherein the intake of food is restricted to six or eight hours. However, the length of the fast depends on the individual and their lifestyle. It is not suitable for everyone because fasting can lead to various side effects, including back pain, nausea, and fatigue. In addition, it is also important to maintain a proper fluid and salt intake and a healthy balance between exercise and rest.
It May Improve Blood Sugar Levels
Many people with diabetes suffer from high blood sugar levels. This can lead to a dangerous condition called ketoacidosis. The symptoms of this condition include excessive thirst and passing large amounts of urine. If you experience any of these symptoms, you should seek immediate medical attention. Fasting may help lower blood sugar levels in the short term.
It May Improve Cholesterol Levels
Studies suggest that fasting may improve cholesterol levels. This may be because a fast reduces insulin levels and impairs the absorption of sugar in the body. In addition, fasting increases glucagon, which releases stored sugar into the bloodstream and causes the liver to mobilize fat and convert it into energy.
It May Improve Insulin Sensitivity
According to recent studies, fasting can improve insulin sensitivity and blood sugar control in people with diabetes or at risk for developing diabetes. Researchers have found that fasting on alternate days significantly reduced blood glucose levels, as well as the resistance to insulin. This decrease in resistance allows for more effective transport of glucose throughout the body and prevents blood sugar spikes. The effect of fasting on insulin sensitivity may depend on several factors.
A recent study of healthy men found that fasting for 16 hours a day for a month helped their gut microbiome to become more diverse. This increase in beneficial bacteria was linked to a reduced risk of obesity and improved metabolic health.
