How much weight would you lose if you didn’t eat anything for a day? and two days? and three days? – Wel.nl


Whether you want to lose weight for the sake of your health or just to shed a few pounds, sometimes there seems to be no end to the various weight loss methods suggested. One of these methods is known as fastingWhere you do not eat food for a certain period of time. The idea behind fasting is for the body to then get into ketosis, where it starts breaking down fat for energy instead of the usual sugar. But how effective is fasting for weight loss? And how much weight can you lose after one, two, or three days without eating?


Not eating for a day usually results in a significant amount of weight loss, but that loss is primarily water weight, not fat. Fasting causes insulin to decrease and adrenaline to increase, which in turn causes water to be released from the kidneys. This is exacerbated by carbohydrate loss when your body is deprived of energy from food. Thus, a one-day fast can lead to weight loss from 0.5 kg to 2.5 kg, depending on the person’s weight and metabolism.

Fasting for two consecutive days will increase the amount of weight loss. In addition to the benefits of the fasting day, the body will continue to break down stored fat for energy instead of muscle. As a result, fasting will have a greater effect on reducing fat. After two days of not eating, weight loss can reach 2.5kg to 4.5kg, depending on the person.

After three days of fasting, your body produces more progesterone to regulate your metabolism, which reduces the effect of ketosis. The body will then begin to break down muscle to provide itself with energy. While this means your body will burn less fat, you will still lose significant weight. Weight loss can be as low as 3.5 kg to 5.5 kg, depending on the individual.

It is important to note that fasting alone is not sufficient for long-term weight loss. Fasting must be combined with a balanced and healthy diet, as well as regular exercise. Fasting can also be harmful to certain groups such as pregnant women, children, the elderly, and people with certain health problems. In addition, fasting can lead to dehydration and negatively affect the metabolism.


Although fasting for one to three days results in significant weight loss, it is not a magic bullet for weight control. However, fasting as part of a balanced and healthy diet can help reduce calorie intake and increase metabolism, which can ultimately lead to weight loss. If you are considering fasting, be sure to do so under professional supervision, and only if it is appropriate for your health, age, and lifestyle.
