Can I exercise while fasting?

You can work out while in a fasted state, but you certainly don’t have to. One study published in the Journal of Exercise Science & Fitness showed that overweight and obese young adult males who engaged in a six-week fasted aerobic workout routine improved their body shape, reduced fasting insulin levels, and increased tissue cell sensitivity to insulin ( 15 ). Their counterparts who participated in the same fitness routine but were not fasting also improved all body weight, shape, and blood lipid metrics, except the insulin sensitivity markers. If you exercise while fasting, stay hydrated and do not work out too intensively. Being hungry during strenuous activity may lead to lightheadedness or reduced workout performance.

How long should I fast according to my age?

Many look for a fasting chart by age on the internet. However, you don’t need to fast according to age. You should focus on choosing one of the various IF patterns and finding the one that works best for you.

What is the hardest stage of fasting?

There is no research on the most challenging stage of intermittent fasting. However, many people new to intermittent fasting claim that the second and third days are the hardest because they feel hungry.
