Can You Do Weight Watchers And Intermittent Fasting At The Same Time

Transitioning towards a healthier lifestyle often includes considering different dietary approaches. Weight Watchers and Intermittent Fasting, both widely acknowledged methods for managing weight, have captured quite a fan base.

Now, the burning question is: Can you do weight watchers and intermittent fasting at the same time?

Let’s delve into the possibility of combining these two popular methods and discover if they can work hand-in-hand to enhance your path to well-being.

What Is Intermittent Fasting?

Intermittent fasting operates as a time-restricted eating regimen characterized by alternating periods of eating and fasting within a scheduled pattern1. It stands distinct from a conventional diet, as it primarily focuses on the timing of meals rather than altering dietary content. This approach doesn’t dictate what you eat but instead redefines when you eat2.

The premise of intermittent fasting revolves around consuming meals solely within a designated time frame. Whether it involves fasting for specific hours daily or restricting eating to one meal on selected days, this method is renowned for its potential to stimulate fat-burning and promote weight loss. Additionally, scientific studies indicate various associated health benefits3.

How Do You Do Intermittent Fasting?

There exist various intermittent fasting methods, all centered around the concept of setting specific, consistent periods for eating and fasting. For example, you might opt to consume meals only within an eight-hour window each day and abstain from eating for the rest of the time. Alternatively, you could follow a routine of eating just one meal a day for a couple of days weekly.

Some popular intermittent fasting approaches include:

  1. The Daily 12 Hour Fast, requiring fasting for 12 hours every day.
  2. The 16/8 Method, involving a daily fasting duration of 14–16 hours and confining eating to an 8–10 hour window.
  3. 5:2 Diet, permitting regular eating for five days a week and restricting calorie intake to 500–600 calories for two non-consecutive days.
  4. Eat Stop Eat, encompassing a 24-hour fast once or twice weekly.
  5. Alternate Day Fasting, in which fasting takes place every other day.
  6. The Warrior Diet, involving small portions of raw fruits and vegetables throughout the day, with one substantial meal consumed at night.

Health Benefits Of Intermittent Fasting

Intermittent fasting is an eating pattern that alternates between periods of eating and fasting. While individual responses can vary, there are several potential health benefits associated with intermittent fasting, supported by scientific research. Here are some of the key health benefits:

1. Weight Loss and Fat Loss: Intermittent fasting can be an effective strategy to lose weight. By restricting the eating window, individuals may naturally consume fewer calories, leading to weight loss. Additionally, fasting periods may increase the body’s reliance on stored fat for energy4.

2. Improved Insulin Sensitivity: Intermittent fasting has been shown to improve insulin sensitivity, helping regulate blood sugar levels. This can be particularly beneficial for individuals at risk of or with type 2 diabetes5.

3. Reduced Inflammation: Fasting periods may reduce inflammation in the body, which is associated with various chronic diseases. This anti-inflammatory effect may contribute to improved overall health6.

4. Heart Health: Intermittent fasting may have positive effects on cardiovascular health by improving risk factors such as blood pressure, cholesterol levels, and triglycerides. These improvements can lower the risk of heart disease7.

5. Brain Health and Cognitive Function: Some studies suggest that intermittent fasting may support brain health and cognitive function. It may enhance brain-derived neurotrophic factor (BDNF), a protein that supports brain function and may help protect against neurodegenerative diseases8.

6. Cellular Repair and Longevity: During fasting periods, the body initiates a process called autophagy, where cells remove and recycle damaged components. This cellular repair process is associated with longevity and may help protect against age-related diseases9.

7. Improved Metabolic Health: Intermittent fasting may help improve various metabolic markers, including blood sugar levels, insulin sensitivity, and lipid profiles. These improvements can contribute to better metabolic health9.

It’s important to note that while intermittent fasting offers potential health benefits, it may not be suitable for everyone, especially those with certain medical conditions. Before starting any fasting regimen, it’s advisable to consult with a healthcare professional to ensure it aligns with individual health needs and goals.

What Is Weight Watchers?

Weight Watchers, now known as WW International, is a weight loss program and community that focuses on a personalized approach to healthy eating and lifestyle. The core principle of Weight Watchers is based on a point system, where each food and drink is assigned a specific number of points based on its nutritional content. Members are given a daily and weekly allowance of points, and they track their food intake to stay within these limits. The program encourages a balanced and flexible approach to eating, allowing individuals to make food choices that fit within their allocated points10.

Over the years, Weight Watchers has introduced different versions of its program, including the SmartPoints system, which takes into account factors beyond just calories, such as sugar and protein content. The goal is to promote healthier food choices rather than just calorie counting.

Health Benefits Of Weight Watchers

Weight Watchers focuses on a holistic approach to health rather than just weight loss. Some of the potential health benefits associated with following the WW program include11:

1. Weight Loss: The program encourages healthier eating habits and increased physical activity, which can lead to weight loss. Shedding excess weight can reduce the risk of various health conditions such as heart disease, type 2 diabetes, and certain cancers.

2. Improved Diet Quality: Weight Watchers promotes the consumption of different food groups and nutrient-dense foods like fruits, vegetables, lean proteins, and whole grains while discouraging high-calorie, low-nutrient foods. This emphasis on a healthier eating pattern can lead to improved overall diet quality.

3. Behavioral Changes: The program focuses on behavioral changes and building healthier habits rather than just to count calories. This can lead to sustainable lifestyle changes that promote long-term weight management and overall health.

4. Support System: Weight Watchers provides a support system through meetings, online forums, and coaching, which can help individuals stay motivated and accountable.

5. Healthier Lifestyle: Participants are encouraged to increase their physical activity, which not only aids in weight loss but also improves cardiovascular health, muscle strength, and overall fitness.

6. Improved Self-esteem: Successfully reaching weight loss goals and adopting healthier habits can boost self-esteem and confidence.

7. Better management of Chronic Conditions: For individuals with conditions like diabetes or high blood pressure, losing weight and adopting a healthier lifestyle can help in managing these conditions more effectively.

It’s essential to note that the success and health benefits of Weight Watchers or any similar program can vary from person to person. Consulting a healthcare professional before starting any weight loss program is advisable, especially for those with underlying health conditions. Additionally, long-term success often depends on continued commitment to the principles learned during the program.

Can You Do Weight Watchers And Intermittent Fasting At The Same Time?

Yes, it’s possible to combine Weight Watchers and intermittent fasting, but it’s essential to do so carefully and in a way that suits your individual needs and preferences. Both approaches have different principles:

1. Weight Watchers (WW): Focuses on a point system where foods are assigned values based on their nutritional content. The aim is to stay within your daily allotted points to manage caloric intake and promote healthier eating habits.

2. Intermittent Fasting (IF): Involves cycling between periods of eating and fasting. Common methods include the 16/8 method (16 hours of fasting, 8 hours of eating) or the 5:2 method (eating normally for 5 days and significantly reducing calories for 2 non-consecutive days).

If you plan to combine these approaches:

Consult a healthcare professional: Before starting any new diet or fasting regimen, it’s crucial to consult with a healthcare professional, especially if you have underlying health conditions.

Adjust your eating window: If you’re practicing intermittent fasting, you may need to adjust your eating window to fit within the points system of Weight Watchers.

Stay hydrated: During fasting periods, it’s essential to stay hydrated. Drink plenty of water to support your body.

Listen to your body: Pay attention to your body’s signals. If you feel unwell or overly fatigued, reconsider the combination or adjust your approach.

Choose nutrient-dense foods: Whether you’re eating within a specific time window or tracking points, prioritize nutrient-dense foods for overall health.

Remember, what works for one person may not work for another. It’s crucial to find a balance that is sustainable and aligns with your health goals. Always prioritize your well-being and make adjustments as needed.


You’ve got the green light if you wish to combine Weight Watchers and Intermittent Fasting. However, let’s dive into the details a bit. People are wonderfully unique, and what works seamlessly for one might need a bit of tweaking for another. Your health journey is like a personalized recipe. Your individual preferences, health considerations, and lifestyle play a starring role.

So, while the “yes” is loud and clear, it’s the “but” that adds that personalized touch. Take a moment to consider what feels right for you. Experiment and find that sweet spot where both methods complement each other. And if you’re feeling a bit uncertain about the mix, reaching out to a healthcare pro or a nutrition expert can provide that extra dash of guidance.
