There are scientific studies that shows the benefits of dieting or fasting, most of the medical community, however, still remains suggests 2,000-2,500 calories a day diet as the best possible choice in the long run.
The following is what is usually recognized as some of the most common consequences of fasting on the human body, so be sure to have a read through, before considering such a thing.
(1) Mood changes
This effect, of course, varies greatly from person to person. Generally speaking, though, it’s not rare to experience certain feelings of anxiety and anger at the beginning, particularly if you’ve never fasted before. At this stage, it’s also quite common to feel tired, as the body begins to get used to food deprivation.
(2) Reduction of cholesterol levels
As food intake ceases, the body is able to use cholesterol as a source of energy. As this process takes place, the amount of plaque being formed inside the arteries diminishes, thus reducing the risk of cardiovascular disease.
(3) Metabolic slowdown
Due to the lack of nutrients entering the body, metabolic rate also decreases in order to preserve energy resources. This slowdown is further influenced by the loss of muscle tissue. The whole process ensures that the energy produced by ketosis will be enough to sustain the body during fasting.
(4) Immune cells regeneration
New evidence suggests fasting may have a rejuvenating effect on the immune system. It also seems to help the body fight against certain conditions such as cardiovascular disease and cancer, while being able to alleviate the side effects of chemotherapy.
A study published in the Cell Stem Cell journal, showed that fasting for periods of 2-4 days at a time can reduce the number of white blood cells
(5) Weight loss
Lacking food as its primary energy source, the body starts by burning glycogen stored in the liver. Once this secondary source is up as well, ketosis starts (usually during the second day of fasting). This mechanism involves burning fatty acids instead of carbs in order to obtain glucose, which in time leads to weight loss.
