Intermittent Fasting for Weight Loss: A Proven Strategy | The Fair Flow

If you are looking to lose weight, you may have heard of intermittent fasting. This eating pattern involves alternating periods of fasting and eating, with the goal of reducing your overall calorie intake. Even though it may seem intimidating, many people have achieved weight loss success with intermittent fasting. 

In this article, we’ll discuss the science behind intermittent fasting and how it can help you achieve your weight loss goals. We'll also provide tips to help you get started with an intermittent fasting plan that works for you.

Intermittent Fasting for Weight Loss

What is Intermittent Fasting?

Intermittent fasting involves eating during specific times and abstaining from eating during other periods of time. It is not a diet, but rather a way of scheduling your meals to optimize your body's ability to burn fat.

Types of Intermittent Fasting

Some of the most common approaches to practicing intermittent fasting are:

  • 16:8 method: This method involves fasting for 16 hours and eating during an 8-hour window each day. 
  • 5:2 diet: This method involves eating a normal diet for 5 days of the week and then restricting calories to 500-600 for the other 2 days.
  • Eat Stop Eat: This method requires fasting for 24 hours, once or twice a week. 
  • Alternate-day fasting: This method involves eating normally one day, and fasting or eating less than 500 calories on the next day. 
  • The Warrior diet: This method involves eating a small portion of raw vegetables and fruits in the evening and then fasting until the next day. 

It is important to note that while intermittent fasting can be an effective way to reduce body weight, it is not for everyone. If you plan on trying intermittent fasting and have a history of disordered eating or serious health concerns, it is recommended to seek advice from a healthcare professional beforehand.

Additionally, it is important to make sure that you are still getting enough nutrients during your eating periods. It can be easy to overeat or make poor food choices when you are not eating regularly, so it is important to plan your meals carefully and make sure you are getting the nutrients your body needs.

Research on Intermittent Fasting

There is some evidence to suggest that intermittent fasting can help with weight loss. A systematic review and meta-analysis of randomized controlled trials found that subjects who followed an intermittent fasting diet lost more weight than those on a traditional, calorie-restricted diet*. Another study in obese individuals showed that after 12 weeks of following an alternate-day fasting schedule, participants had a significant reduction in body fat, BMI, and waist circumference.

In addition to helping with weight loss, there are some studies that suggest intermittent fasting can have positive effects on other health markers as well. One study found that participants with type 2 diabetes who followed an alternate-day fasting schedule experienced improvements in insulin sensitivity and blood pressure.

Intermittent Fasting To Lose Weight

Intermittent fasting helps with weight loss by triggering changes in your metabolism. During periods of fasting, your body begins to use stored fat for energy rather than the carbohydrates and sugars that it normally gets from food. 

This shift in metabolic activity can help you burn more calories and over time lead to greater weight loss. Additionally, intermittent fasting can help reduce levels of insulin in the blood, which may lead to improved fat breakdown and increased weight loss.

Benefits of Intermittent Fasting for Weight Loss

Intermittent fasting can be an effective weight loss tool for several reasons. First, it will reduce your overall calorie intake: eating during certain hours of the day results in eating fewer calories, which can lead to weight loss. 

Second, intermittent fasting does not entail complex meal preparations or rigorous calorie tracking, as is necessary with a typical low-calorie diet. Instead, it simply encourages you to skip meals during designated fasting periods. In fact, research has shown that intermittent fasting can be just as effective as continuous calorie restriction for shedding pounds. 

Third, intermittent fasting can help you lose fat while preserving muscle mass. This is important because losing muscle can slow down your metabolism and make it harder to lose weight in the long run. 

Finally, intermittent fasting can help reduce inflammation in the body, which can contribute to weight gain and other health problems. By giving your body a break from constantly digesting food, you can reduce stress on your digestive system and allow your body to focus on repairing and healing itself.

Starting intermittent fasting for weight loss

An intermittent fasting pattern is typically based on a specific time frame of fasting and eating. Before beginning your weight loss journey, it is important to choose an intermittent fasting routine that works best for you and your lifestyle. 

Tips for Starting Intermittent Fasting

Starting a new diet can be challenging, but these tips can help make the transition to intermittent fasting easier:

  • Start Slow: Begin by fasting for a shorter period, such as 12-14 hours, and gradually increase the fasting window over time.
  • Stay Hydrated: To avoid dehydration during periods of fasting, it is recommended to drink plenty of water and other calorie-free drinks.
  • Eat Whole Foods: Focus on consuming nutrient-dense, whole foods during eating periods to ensure you're getting adequate nutrition.
  • Listen to Your Body: Pay attention to how your body feels during fasting periods and adjust as needed. If you feel lightheaded or unwell, break the fast and eat.
  • Stay Busy: Keep yourself occupied during fasting periods to avoid focusing on food. Try reading, going for a walk, or engaging in another activity.

Keep in mind that intermittent fasting alone is not the solution for losing weight. It's important to combine it with a balanced, healthy diet and regular exercise to see the best results. 

What to Eat During Intermittent Fasting

Foods to Eat

When it comes to intermittent fasting, it's not just about when you eat, but also what you eat. During your eating window, it's important to consume foods that will provide your body with the necessary nutrients to function properly. Here are some healthy foods to eat during intermittent fasting:

  • Lean proteins such as chicken breast, beans, and tofu
  • Fruits like apples, berries, and oranges
  • Vegetables such as spinach, broccoli, and cauliflower
  • Whole grains like brown rice and quinoa
  • Healthy fats such as nuts, seeds, and olive oil
  • Dairy products like cottage cheese, and Greek yogurt

Foods to Avoid

While there are plenty of healthy foods to eat during intermittent fasting, there are also some foods that you should avoid. These include:

  • Processed foods like chips and cookies
  • Sugary drinks like soda and juice
  • Fried foods like french fries 
  • High-fat meats like bacon and sausage
  • Refined grains like white bread and pasta
  • Alcohol

By avoiding these foods, you can make sure that you're getting the most out of your intermittent fasting regimen. Remember, the key to losing weight with intermittent fasting is to focus on healthy, nutrient-dense foods during your eating window.

Possible Risks and Side Effects

Intermittent fasting can be an effective way to lose weight, but it is important to be aware of potential risks and side effects:

  • Hunger: Skipping meals can lead to feelings of hunger, which may be difficult to manage. This can lead to overeating during the eating periods, which can counteract the weight loss benefits of intermittent fasting.
  • Headaches: Some people may experience headaches during fasting periods, especially if they are new to intermittent fasting.
  • Low Blood Sugar: Fasting can cause your blood sugar levels to drop, which can lead to dizziness, lightheadedness, and fatigue.
  • Dehydration: Not drinking enough water during fasting periods can lead to dehydration, which can cause headaches, fatigue, and other symptoms.
  • Constipation: Some people may experience constipation during the fasting periods, especially if they are not eating enough fiber-rich foods during the eating periods.
  • Bad Breath: Fasting can cause bad breath, especially if you are not drinking enough water or if you are consuming sugary or acidic beverages during the eating periods.

Before beginning an intermittent fasting regimen, it is recommended that you consult with your healthcare provider. It is important to listen to your body and stop fasting if you experience any severe or persistent symptoms.

Overall, intermittent fasting can be a safe and effective way to lose weight, but it is important to be aware of the risks and side effects. By staying hydrated, eating a balanced diet, and listening to your body, you can minimize these risks and enjoy the benefits of intermittent fasting.

fasting and weight loss


Intermittent fasting can be an effective tool for weight loss, but it is not a magic solution. It requires discipline and a commitment to sticking to a fasting schedule. If you are considering intermittent fasting, it is important to consult with a healthcare professional to ensure it is safe for you.

There are many different approaches to intermittent fasting, so it is important to find one that works for you and your lifestyle. 

Remember that weight loss is not the only benefit of intermittent fasting. It has also been shown to improve insulin sensitivity, lower inflammation, and improve overall health. However, it is important to approach intermittent fasting as part of a healthy lifestyle that includes regular exercise and a balanced diet.

Finally, it's crucial to have patience and set realistic goals. Intermittent fasting is not a quick fix, and sustainable weight loss takes time and effort. Stay consistent with your fasting schedule and focus on making healthy choices, and you will see results over time.
