Many people skip breakfast, which is a bad habit for their general health and fitness, but it can also adversely affect their brains. Never skip breakfast and make a habit of eating a nutritious breakfast at the start of every day.
I do intermittent fasting for more than 2 years now and breakfast is no longer a meal for me.
I don't know if my brain is affected by intermittent fasting but I feel great much more compared to my past lifestyle of eating 3 meals a day and with snacks between meals.
