One Meal a Day

Tim Ferriss has discussed the concept of eating one meal a day (OMAD) with various guests on his podcast. Here are some insights:

1. General Stan McChrystal's Routine: General Stan McChrystal adopted the practice of eating one meal a day during his military service. He preferred this method as he found it easier to defer gratification and eat a substantial dinner after a long day. He drank coffee and other beverages throughout the day to maintain energy levels but occasionally supplemented with snacks like pretzels when necessary 1.

2. Practicality in Extreme Situations: Tim Ferriss shared that while working with General McChrystal, the one meal a day routine was often out of necessity due to demanding schedules and expectations within the organization. Although Ferriss mentioned that this practice suited McChrystal’s metabolism, he advised others not to feel pressured to follow it if it didn’t work for them 2.

3. Penn Jillette’s Approach: On a more extreme end, Penn Jillette spoke about his version of intermittent fasting where he fasted for 23 hours and had a one-hour feeding window. During this window, he consumed a large quantity of nutrient-rich but low-calorie foods. This method helped him manage his weight effectively while also satisfying his dietary needs within a short period 3.

These discussions highlight both the benefits and practical considerations of adopting an OMAD regimen. The suitability of OMAD highly depends on individual metabolic responses and lifestyles.
