Science-Proven Benefits of Fasting


Fasting is withholding from all or some food or drink consumption for a fixed duration, typically lasting between 1 to 3 days. Around the world, fasting has been a crucial element to various religions and cultures as a centuries-old tradition. Another subtype of fasting, known as intermittent fasting, lasts for as little as a few hours or up to a few days and switches between fasting and eating. Among the numerous health benefits of fasting, weight loss is among the most noticeable.

Fasting regulates calorie consumption and increases metabolism to promote weight loss.

Fasting periods in animals short-term, as indicated by some research, may lead to weight loss and a possible increase in metabolism due to the rise in levels of norepinephrine, a neurotransmitter. In addition, it was demonstrated in another review that as much as a 9% reduction in body weight is possible through 24-hour fasting. During 3 to 6 months, body fat may also be drastically burned off. When long-term calorie limitation was compared with intermittent fasting in a different review, intermittent fasting had far more promising results in weight loss.

Fasting regulates triglycerides, cholesterol, and blood pressure levels and may support a healthy heart.

Around the world, nearly one-third (31.5%) of all deaths are attributed to heart disease, which has become the top cause of death worldwide. Improved heart health has been linked through research to routine periods of fasting. Compared between overweight individuals and a control group, according to one review, various risk factors associated with heart disease and total cholesterol levels may be lessened with alternate-day fasting.

Blood sugar levels are kept balanced with fasting.

To keep a constant supply of energy, the body gradually transitions from carb metabolism to fat metabolism during fasting periods, slowing down insulin production. Insulin resistance may easily be combatted by fasting intermittently. As the body's natural response to insulin improves, balanced blood sugar levels and fewer peaks and drastic drops will result.

Fasting may do wonders for your overall mood.

Fasting may provide relief for depression since it has a direct impact on your brain's supply of endogenous opioids, serotonin, and additional mood-boosting neurotransmitters. It's also been proven that an increased sense of elation and decreased negative feelings such as irritation and stress occur with fixed calorie consumption and fasting. In a review conducted in 2008 with individuals diagnosed with depression, symptoms of depression lessened over half a year when daily calorie consumption was reduced by 25 percent, and harmful side effects were not noticeable.

  • Bone health is also improved with fasting as it directly impacts the hormones that regulate bone metabolism and the reshaping process of bones.
  • As indicated by studies, appetite has been shown to remain the same or reduce during intermittent fasting periods generally.
  • Intermittent fasting diets generally are more successful in how long people stick to them than other diets, as short-term studies propose.
