We always hear about many exercise and diet trends that are backed up by science or not. Fasting has become a popular trend by refraining from food and drink for a period of time. However, fasting has been seen in many religions and cultures in the past century.
There is plenty of research conducted mostly on animals, but the results have been clear. There are different types of fasting: intermittent, longer, and extended fasts. One of the major differences is how long a fast is done. Usually, the fast is done intermittently. Those considering fasting should consult with their doctor before attempting any type of fast. There is clear evidence that there are health benefits to fasting.
Fasting Benefit #1: Improves Body Composition
It makes sense that less consumption of caloric intake will help one to lose weight. However, fasting is not the same as starvation. It means that the duration of eating is shorter, but the amount of nutrients and daily caloric needs are still being met.
In a study involving 24 participants, they were to exercise and participate in intermittent fasting during an eight hour window. For the next 30 days, participants were assessed with weight training and ingesting calories during the intermittent fasting time frame. It was concluded that their lean mass from the first day to the last was significant in resting energy expenditure. Intermittent fasting along with resistance training can decrease body fat and enhance body composition.
