Meals Skipping: Routine vs. Random: Weight Loss or Weight Gain

Almost all of us have skipped a meal or two in the hope of losing a few pounds. The overall experience for most people in the end is that its been it’s of little help. However, some individuals skip meals much more regularly.  Does this behavior help weight loss or even weight maintenance?  Are there any dangers or real benefits? In order to answer these questions, you need to understand the three types of skipping meals:

1. Routine skipping meals: Skipping 1 or 2 meals on most days. 10% of Americans never have breakfast( in males age 18-34 its 28%) while 35% of Americans skip lunch.

Meal skipping in this group includes people who report that are “not hungry” at breakfast or have no time for breakfast.The “not hungry” group eats late at night or in the middle of the night and is truly not hungry on awakening. A less frequent skipping patterns is  seen in those that work through lunch or work odd hour  or  night shifts. Often lunch is skipped in these groups. Usually this is associated with weight gain.

2.Random meal skippers: 50% of Americans skip breakfast and/or lunch once or twice a week. Not having enough time is the usual reason for missing a meal. When it occurs rarely, often not planned is probably harmless.

3. Alternate day fasting: Another group of people attempt to lose weight by intermittent fasting.This pattern of meal skipping is more of a fad than a proven weight loss technique. Less than 1% of the population has tried this. While the weight loss results have been variable, it appears to offer a safe and effective technique for some people.

Skipping Breakfast or Lunch Leads to Overeating and Loss of Control Day’s Food

Eating breakfast everyday is the first critical step on the path towards successful weight loss. Skipping breakfast remains the most common mistake made by people attempting to lose weight. Breakfast, especially one including proteins such as eggs, ham, cheese, bacon or high-protein bars or cereals, stabilizes the blood sugar for the rest of day and ensures better choices at lunch.

The National Institutes of Health reports: ” Skipping breakfast, in particular, has been associated with obesity in several scientific studies, implying that missing a meal can make you so hungry you’ll consume double or triple a normal meal’s calories when you eat next”

When you skip any meal  your blood sugar falls throughout the day and you arrive at the next meal  not only hungry but with a low blood sugar. The result is a low energy level, less exercise and physical activity.   Making bad choices like eating at fast food restaurants or having large meals is the result. Experiencing low blood sugars at lunch or late in the afternoon when lunch is skipped often leads to overeating and loss of control.  Individuals working in schools or offices who skip breakfast and are hungry by lunch are often vulnerable to the “bad choices” that coworkers make and are likely to go-along with the crowd.

Published in Appetite in 2008: ”   subjects who skipped lunch or dinner most often burned fewer overall calories and spent less total time exercising than subjects who rarely skipped those meals.”

Here are the scientific results of several studies regarding skipping, metabolism and weight loss or gain:

Effect of Skipping Breakfast(and /or lunch) on Metabolism

In 2007 researchers at the National Institute of Health studies healthy normal weight subjects for 16 weeks. For  two months, the  subjects ate three meals a day. For another eight-week period, they skipped two meals but ate the same number of calories in one evening meal. They essentially starved themselves or 8-10 hours. Each subject consumed the same amount of calories each day regardless of whether they ate one or three meals, and all subjects maintained their body weight within 2 kg of their initial weight throughout the 6 month period . Most physiological variables measured, including   heart rate, body temperature and blood chemicals, were unaffected by meal skipping. However, they found that during the skipping phase there was slowing of metabolism and elevated glucose and insulin indicating pre-diabetes. There was no weight differences at the end of the skipping period.

Skipping meals slows the metabolism down. When the meal finally arrives at the end of the skip the food transforms into fat more readily and gets deposited often around the belly. When your body enters into starvation mode, it looks for new sources of energy. Your metabolism starts transforming fat into energy. This is often associated with:

  • nausea
  • constipation
  • fatigue
  • kidney stress
  • low blood pressure
  • low blood sugar
  • irritability

 Effect of Skipping Full Days Food on Body Weight

Researchers at Louisiana State University and the National Institutes of Health Studied the effect of alternate day eating on subjects with asthma. Over the course of the study there was an 8% reduction in body weight compared to subjects eating the same calories every day. Improvement in lung function, asthma and mood and energy was found in the alternate day eaters. They had “lower cholesterol and triglycerides, “striking” reductions in markers of oxidative stress and increased levels of the antioxidant uric acid. Markers of inflammation were also significantly lower.”

skipping meals and weight changes

The conclusion, say the authors of the  alternate day meal-skipping study, is that skipping meals as part of a controlled eating plan that results in lower calorie intake can produce weight loss and improvement in some measurements of health. However, the weight loss did not apply to those people who randomly skip a meal or even those that regularly skip breakfast.

Summary of Studies on Skipping Meals and Weight Loss:

1. Routine skipping of meals produces no weight loss and even weight gain.
2. Random skipping of meals  (1-2 times a week) is insignificant–no weight gain or loss
3. Alternate day fasting: may be helpful but for only limited number of dieters
