According to a 2023 study, skipping meals and shorter meal intervals were associated with increased cardiovascular disease and all-cause mortality risk in adults. So, is OMAD fasting safe given the extreme restriction involved?

Most One Meal A Day (OMAD) fasters adhere to a 23-hour fasting window, leaving a 1-hour period for eating. This popular form of intermittent fasting has gained traction for its simplicity, but understanding the correct duration is crucial for both safety and effectiveness.

According to a study on healthy men, autophagy markers, like the protein LC3-II, rise significantly after just 16 hours of fasting. This scientific finding confirms that consuming just one meal a day can indeed trigger autophagy, a vital cellular recycling process.

In recent studies, a 2022 review noted that restricting eating to a small window can aid weight loss by creating a calorie deficit. While this is a known benefit, many wonder: how long can I safely do OMAD, and what are the long-term implications of this extreme dietary pattern?

While some short-term studies show potential benefits, most healthcare professionals do not endorse OMAD as a long-term strategy, citing concerns like nutritional inadequacy and rebound weight gain. Understanding how long you can safely do OMAD requires balancing its appeal with significant health risks.
