&gt; A few friends of mine fast intermittently and train in the morning before eating but it&#x27;s beyond me how that is not just pure torture.<p>It&#x27;s just habit. I stopped eating breakfast in primary school and always preferred doing sports in the morning. Currently doing fasted weightlifting&#x2F;cardio 5x a week first thing in the morning.<p>I&#x27;m currently doing only one big meal a day for lunch so technically that&#x27;s fasting since 2pm the previous day.
