Diet Myth or Truth: Fasting Is Effective for Weight Loss

Fasting is an age-old practice, often done for religious reasons, but fasting for weight loss is still capturing the public imagination. You can find dozens of do-it-yourself plans touting the unproven benefits of fasting, ranging from flushing "poisons" from the body to purging 30 pounds of fat in 30 days.

It's true that fasting -- that is, eating little to no food -- will result in weight loss, at least in the short term. But the risks far outweigh any benefits, and ultimately, fasting can cause more harm than good.

Typical Fasting Weight Loss Plans

Fasting regimens vary, but the basic premise usually starts with a strict regimen allowing only water, juice and/or some kind of laxative concoction. Some plans allow a few solid foods, but are still called fasts because they provide so few calories.

Not all fasts are created equal. Some can be perfectly safe, such as medical fasts supervised by a physician. Religious and cultural fasts are typically undertaken as an act of devotion, last from 24-48 hours, and are not intended to promote weight loss.

Fasts lasting a day or two are unlikely to be dangerous for most healthy adults. But high-risk people, the elderly, anyone with a chronic disease, pregnant women, and children are advised against any type of fasting.

The real danger lies in staying on the fast for prolonged periods, anywhere from three days to a month.

Dangers of Fasting for Weight Loss

When you dramatically reduce your calorie intake, you will lose weight. But it can also cause all kinds of health problems, including muscle loss. Further, when you start fasting, your body goes into conservation mode, burning calories more slowly.

Keep in mind that the initial weight lost on a fast is primarily fluid or "water weight," not fat. And when you go back to eating, any lost weight usually gets a return ticket back. Not only do most people regain weight lost on a fast, they tend to add a few extra pounds because a slower metabolism makes it easier to gain weight. Worse, the weight that is regained is likely to be all fat -- lost muscle has to be added back at the gym.

Side effects of fasting include dizziness, headaches, low blood sugar, muscle aches, weakness, and fatigue. Prolonged fasting can lead to anemia, a weakened immune system, liver and kidney problems, and irregular heartbeat. Fasting can also result in vitamin and mineral deficiencies, muscle breakdown, and diarrhea. When you drink laxative concoctions during a fast, there is an increased risk of fluid imbalance and dehydration.

The risks get more complicated and severe the longer you stay on a fast, or if you repeatedly go on fasts.

When and How to Wash Your Hands

Handwashing is one of the best ways to protect yourself and your family from getting sick. Learn when and how you should wash your hands to stay healthy.

How Germs Spread
Washing hands can keep you healthy and prevent the spread of respiratory and diarrheal infections from one person to the next. Germs can spread from other people or surfaces when you:

• Touch your eyes, nose, and mouth with unwashed hands
• Prepare or eat food and drinks with unwashed hands
• Touch a contaminated surface or objects
• Blow your nose, cough, or sneeze into hands and then touch other people’s hands or common objects

Key Times to Wash Hands
You can help yourself and your loved ones stay healthy by washing your hands often, especially during these key times when you are likely to get and spread germs

• Before, during, and after preparing food
• Before eating food
• Before and after caring for someone at home who is sick with vomiting or diarrhea
• Before and after treating a cut or wound
• After using the toilet
• After changing diapers or cleaning up a child who has used the toilet
• After blowing your nose, coughing, or sneezing
• After touching an animal, animal feed, or animal waste
• After handling pet food or pet treats
• After touching garbage

During the COVID-19 pandemic, you should also clean hands:
After you have been in a public place and touched an item or surface that may be frequently touched by other people, such as door handles, tables, gas pumps, shopping carts, or electronic cashier registers/screens, etc.
Before touching your eyes, nose, or mouth because that’s how germs enter our bodies.

Follow Five Steps to Wash Your Hands the Right Way
Washing your hands is easy, and it’s one of the most effective ways to prevent the spread of germs. Clean hands can stop germs from spreading from one person to another and throughout an entire community—from your home and workplace to childcare facilities and hospitals.
Follow these five steps every time.

1. Wet your hands with clean, running water (warm or cold), turn off the tap, and apply soap.
2. Lather your hands by rubbing them together with the soap. Lather the backs of your hands, between your fingers, and under your nails.
3. Scrub your hands for at least 20 seconds. Need a timer? Hum the “Happy Birthday” song from beginning to end twice.
4. Rinse your hands well under clean, running water.
5. Dry your hands using a clean towel or air dry them.

Use Hand Sanitizer When You Can’t Use Soap and Water
Washing hands with soap and water is the best way to get rid of germs in most situations. If soap and water are not readily available, you can use an alcohol-based hand sanitizer that contains at least 60% alcohol. You can tell if the sanitizer contains at least 60% alcohol by looking at the product label. Sanitizers can quickly reduce the number of germs on hands in many situations. However,

• Sanitizers do not get rid of all types of germs.
• Hand sanitizers may not be as effective when hands are visibly dirty or greasy.
• Hand sanitizers might not remove harmful chemicals from hands like pesticides and heavy metals.

How to Use Hand Sanitizer

1. Apply the gel product to the palm of one hand (read the label to learn the correct amount).
2. Rub your hands together.
3. Rub the gel over all the surfaces of your hands and fingers until your hands are dry. This should take around 20 seconds.
