OMAD

With so much research on the health benefits of intermittent fasting (IF), it should come as no surprise that fasting has become such a popular health trend. The unique thing about intermittent fasting is it has benefits no matter how long you fast but can vary based on this time frame. Most forms of intermittent fasting consist of a fasting window (i.e. 20 hours) and a fed window (i.e. four hours), but OMAD (one meal a day) is slightly different.  

 

What is OMAD?

O.M.A.D. stands for one meal a day. This is a form of intermittent fasting where you consume all of your calories and nutrients in one meal. Typically this meal is large and considered a part of a one-hour feeding window, followed by a 23-hour fasting window. 

 

What are the Benefits of Only Eating One Meal A Day?

The health benefits of OMAD parallel those of traditional intermittent fasting. Some of these benefits include: [1] [2]

  • Improving blood glucose and insulin sensitivity
  • Reducing inflammation
  • Reducing bloating
  • Improving GI health
  • Reduced caloric consumption (fat loss)
  • Improved cognitive functioning & mental clarity
  • Reduced oxidative damage
  • Promoting longevity & healthy aging
  • Better sleep.

Why Would You Only Eat One Meal A Day?

Eating only one meal a day can be beneficial for busy, on-the-go people. Restricting your eating window to one set timeframe, the time spent eating and prepping meals is reduced. This can also help reduce anxiety around eating, how much to eat, overeating, and snacking. 

If you are the type of person that tends to eat while bored or finds themselves snacking all day, OMAD might be helpful. 

 

Is OMAD Safe?

As with any dramatic change to your diet, it is always recommended that you first speak with your physician. Intermittent fasting, however, has been shown by research to be safe. There are a few health concerns, however, that you should be aware of. 

It is important to make sure that you are obtaining all of your necessary nutrients during the feeding window. This can be tough when eating only one meal a day. That means enough calories, macronutrients (specifically fat and protein), and micronutrients (vitamins and minerals). [3]

 

OMAD Tips & Recommendations

If you want to try OMAD here are a few tips and tricks that might make the experience a little easier:

  • Drink plenty of water during your fasting window
  • Pre-plan meals so that you make sure you are getting the right nutrients your body needs
  • Try adding electrolytes and/or bone broth to your feeding window to help prevent any electrolyte deficiencies
  • Add plenty of salt to your food in order to maintain sodium levels
  • Try a fasting app (like Zero) to help time your fasts better
