Alternate Day Fasting Vs OMAD? Which should you use?

Alternate day fasting vs OMAD

Alternate day fasting is an intermittent fasting schedule that calls for 36-hours of fasting accompanied by a normal day of eating then fasting again.  Just like other intermittent fasting schedules, it comes with lots of health benefits and can help you lose weight too. Alternate day fasting has been praised for its weight loss effects, and it’s easy to see why. With this eating approach, you’re missing out on an entire day of eating. This helps you create and maintain a calorie deficit week after week allowing you to lose weight. A common alternate-day success story is that of Sumaya, a woman who lost 50 pounds in 8 months with alternate-day fasting.

 

OMAD, also known as the one meal a day diet, is another extreme intermittent fasting schedule that calls for 23-hours of fasting and 1-hour of eating. With this eating approach, all your food is consumed as part of one big meal. OMAD diet can help lose weight because there’s only so much you can eat within 1 hour. However, many critics say it’s likely that you’re not getting all the nutrients you need due to its limited eating window.

How to do alternate day fasting

With alternate day fasting, you fast for at least 36-hours before eating. If your last meal is an 8-pm dinner on Monday, your next meal will be after 36-hours, Wednesday at 8 am. On your eating day, you eat all your meals, breakfast, lunch, and dinner.  It’s very much a fast-eat–fast-eat approach. On fasting days, you’re only allowed zero-calorie drinks such as water, coffee, and tea. However, these have to be plain with no added sugar or creamer. As you’re missing out on several full days of eating, you can lose 2 pounds a week, if not more. Another way to get started is with the modified alternate-day fasting. This schedule allows you to eat at least 500-calories on your fasting day, about 20% – 25% of your total daily calories. This approach makes it easier for beginners to adjust their eating habits.

OMAD also known as one meal a day is an intermittent fasting schedule that calls for 23-hours of fasting and 1-hour of eating. Like other intermittent fasting schedules, it’s not about what you eat but about when you eat. On this diet, all your food is consumed as part of one big meal during your 1-hour eating window. During your fasting window, you are allowed zero-calorie drinks such as tea, coffee, and water. Staying hydrated is a good way to reduce hunger pangs and fatigue when fasting. Your one meal can either be breakfast, lunch, or dinner. Experts recommend that you schedule it after your most active part of the day to avoid breaking your fast due to hunger. For example, if you go to the gym at 4 pm and are on the OMAD diet, it’s better to schedule your meal after your workout.

 

Alternate day fasting and weight loss

Alternate-day fasting is often praised for its quick weight loss effects because it helps create and maintain a calorie deficit. When eating on alternate day fasting, you’re missing out on a full day of eating several times every week.  For example, for someone eating about 1500 calories a day, with alternate-day fasting, they’re missing out on at least 3- 4 days. That’s a 4500 – 6000 calorie deficit.  To lose 1 lb, you need to burn at least 3500 calories. Alternate day fasting allows you to achieve this caloric deficit due to the many days you forego eating. Expect to lose at least two-pound every week.

OMAD and weight loss

To lose weight, you need to create a calorie deficit. You can do this by burning off extra calories consumed or limiting the number of calories you consume. With the OMAD diet, the number of calories you consume is limited due to the short 1-hour eating window available. There’s only so much you can eat within that 1-hour eating window. This is what allows you to lose as much as 2 pounds per week on the OMAD diet like other intermittent fasting schedules.

 

Alternate day fasting pros

  • Promotes weight loss

One of the reasons alternate day fasting is so popular is that it can help you lose weight. Studies have shown that this eating approach is just as effective as calorie reduction. With 36-hours of fasting, you’re going for a full day without food several times each week. This creates a calorie deficit that allows you to lose weight. Expect to lose at least two pounds every week. If you don’t like counting calories for weight loss, alternate day fasting is a better alternative. Here is one of the best alternate-day success stories from Sumaya, a woman who lost 50 pounds in 7-months with alternate-day fasting.
