Drawbacks

16/8 intermittent fasting may be associated with many health benefits, but it does come with some drawbacks and may not be right for everyone.
Restricting your intake to just eight hours per day can cause some people to eat more than usual during eating periods in an attempt to make up for hours spent fasting.
This may lead to weight gain, digestive problems and the development of unhealthy eating habits.
16/8 intermittent fasting may also cause short-term negative side effects when you’re first getting started, such as hunger, weakness and fatigue — though these often subside once you get into a routine.
Additionally, some research suggests that intermittent fasting may affect men and women differently, with animal studies reporting that it could interfere with fertility and reproduction in females (5Trusted Source).
However, more human studies are needed to evaluate the effects that intermittent fasting may have on reproductive health.
In any case, be sure to start gradually and consider stopping or consulting your doctor if you have any concerns or experience negative symptoms.
SUMMARY
Restricting daily food intake may cause weakness, hunger, increased food consumption and weight gain. Animal studies show that intermittent fasting may impact men and women differently and may even interfere with fertility.
