Some one-meal-a-day diet plans, also referred to as intermittent fasting, are known as Skipped Meal, Condensed Eating Window, Early and Late, Single 24, and the Alternating Day Fast, reports Marks Daily Apple, a health resource website from former elite endurance athlete Mark Sisson. However, eating one meal a day can have negative effects and is not the best way to lose or maintain weight, according to SFGate.
Several variants of one-meal-a-day diet plans are available on Marks Daily Apple. The Skipped Meal diet plan involves missing meals on an unplanned basis. This is based on the premise that people are not always hungry at mealtimes and should not eat as a matter of routine. A skipped meal can also be planned at a convenient time. In the Condensed Eating Window plan, food is consumed within a set number of hours every day, depending on the person's schedule and preference. The Early and Late diet plan involves dividing the daily intake of food into an early morning and late afternoon meal.
The Single 24 fast involves eating a normal meal at dinnertime and then fasting until the following evening, explains Marks Daily Apple.The Alternating Day fast is a more stringent diet plan that involves eating either normal or reduced-calorie food on one day, followed by complete fasting with only small amounts water, juice and tea the following day. This can be undertaken once or twice a year.
Consuming one meal per day rather than the traditional three meals per day is feasible for a short duration, but it can significantly increase cholesterol, blood pressure and morning fasting blood sugar levels, reports the United States Department of Agriculture. Eating one meal a day can have adverse medical consequences, including a weaker immune system, warns SFGate.
