Fasting and Weight Loss: Does Fasting Help You Lose Weight?


When it comes to weight loss, it seems that there are countless fad diets and workout regimes out there.

But what about fasting?

Is fasting really a viable weight loss strategy?

In this article, we’ll take a look at the science behind fasting and see if it really helps you lose weight.

What is Fasting?

Fasting is a practice where you abstain from food or drink for a certain period of time.

The length and frequency of fasts can vary, but they are typically done for religious or spiritual reasons, to improve health, or as a weight-loss tool.

While fasting has been shown to have many benefits, it’s important to remember that it’s not a one-size-fits-all approach.

Some people find that intermittent fasting works better for them than complete fasting, while others find that traditional fasting approaches work better for them than modified fasting.

Types of Fasting

There are a few different types of fasting, which can help with weight loss.

1. Short-term fasting refers to eating fewer than 600 calories per day for two or more consecutive days.

This type of fasting has been shown to help people lose weight and improve their overall health. (1)

2. Intermittent fasting is a way to fast intermittently, meaning you eat between meals instead of all at once.

This type of fasting can also help you lose weight and improve your overall health. (2)

3. Long-term fasting is a more extreme form of intermittent fasting, where you fast for extended periods of time (more than 24 hours).

While long-term fasting is not recommended for everyone, it has been shown to help people lose weight and improve their overall health. (3)

The Benefits to Fasting for Weight loss

There are many benefits to fasting for weight loss namely:

1. It helps you break your addiction to food.

When you fast, your body begins to burn fat instead of glucose, which is the main source of energy for our cells.

This can help you lose weight because your body is using stored fat instead of glucose to fuel its activities.

2. Another benefit of fasting is that it can help reduce inflammation throughout your body.

High levels of inflammation are linked with obesity and chronic diseases, so fasting can be a powerful way to reduce your risk of these conditions.

3. By fasting, you also improve your blood sugar levels, which can help prevent obesity and type 2 diabetes.

4. Finally, fasting can also help improve your mood and mental well-being.

When you fast, your body releases substances called ketones, which have been shown to have positive effects on mood and cognitive function.

How does Fasting help You Lose Weight?

Caloric restriction (fasting) promotes weight loss because of increased ketosis.

After the first day or two, blood glucose, insulin and the nutrient signaling pathways that are regulated by mTOR kinase protein become inactive.

This fasting process switches the body’s energy source to fat, causing it to produce ketones on their own. It also stimulates metabolic function and can lead to weight loss and as well as many other health benefits.

With ketosis, you can continue your weight training routine without needing protein to fuel the process.

Ketosis offers an additional bonus of burning fat stores, which makes it possible to enter a state of caloric restriction in a more sustainable way.

How to fast for weight loss

There is a lot of talk about fasting and whether or not it can help you lose weight.

The answer, according to some experts, is yes – but it’s not as simple as just skipping breakfast or dinner.

The steps below as discussed by Jenna Fletcher include:

1. Set your goals

People who are trying to lose weight, improve their health and metabolic health typically have a specific goal in mind.

For example, they may want to focus on losing weight, improving overall health, or helping with metabolic issues by fasting.

This will help them decide on the most suitable fasting method, plan out how many calories and nutrients they need to consume.

2. Choose between different fasting methods to try

It is generally advised that a person should stick with one fasting method for at least one month before trying another.

During fasting, you can use a variety of methods to enable your body to fall into a fasting state. Pick the one that seems most suitable for you and stick with it.

These fasting methods include:

  • Eat Stop Eat
  • Warrior Diet
  • Leangains
  • Alternate Day Fasting

To test the effectiveness of one fasting method, people usually need to follow it for at least a month.

It’s important that individuals who are under medical care seek advice from their health care providers before beginning any new fasting strategy.

You do not need to eat certain kinds of food, or avoid other foods. It is possible to follow a diet that will help promote overall health and weight loss.

One specific way to achieve this is through the intake of vegetables, which make up a healthy part of the diet in general.

Binging on sugar and junk food on fast days can make it easier to gain weight, prevent health progress, and make it difficult to lose weight.

On top of this, it is also important to drink water or other no-calorie beverages every day during the fast days.

3. Calculate your calorie needs

No special diet is required when on a fast, but this doesn’t mean calories don’t count.

People who want to lose weight need to create a calorie deficit, while those looking to gain weight need to consume more calories than they use.

There are many tools that allow people to track their caloric needs and determine how many calories they need to consume each day in order to either gain or lose weight.

A person could also speak to their healthcare provider or dietitian for guidance on how many calories they need.

4. Figure out a meal plan that works for you

A person trying to lose or gain weight has the option of planning their daily diet and what they will eat.

By planning ahead and constantly checking your diet, you can manage caloric intake and make sure that the diet you are following is nutrient rich.

Meal planning helps people maintain their calorie count, but also create a well-stocked pantry — perfect for cooking and snacking.

5. Make your calorie intake count

The amount of calories that your body can consume when fasting largely depends on the type of nutrients and macronutrients that are consumed.

There’s no reason to give up junk food altogether. But people should think about what they’re eating, and choose healthy options so that they can get the most benefits from their meals.

When should you fast for weight loss?

There is no one-size-fits-all answer to this question, as the best time to fast for weight loss will vary depending on your individual goals and body composition.

However, there are a few general principles that can help you fast effectively for weight loss.

The first thing to remember is that fasting is not magic – it won’t work if you only do it sporadically or without having a well-planned plan in place.

Rather, fasting should be part of a comprehensive weight loss strategy that includes diet and exercise.

In fact, research has shown that fasting can actually help you lose more weight when combined with a healthy diet and regular exercise.

To get the most out of fasting for weight loss, make sure to follow the following guidelines:

1. Start with short fasts

If you’re just starting out, shorter fasts (between 24 and 48 hours) are generally more effective than longer fasts (more than 72 hours).

This is because they allow your body to transition more easily from an energy storage mode (carbohydrate reserves) to an energy use mode (fat stores).

Additionally, shorter fasts allow you to keep more of the nutrients your body needs while still losing weight.

2. Follow a calorie-controlled diet

Fasting without a well-planned, calorie-controlled diet is not going to be very effective in terms of weight loss.

In fact, you might even see some negative effects, such as increased hunger and cravings.

Instead, make sure to follow a healthy diet that includes plenty of fruits, vegetables, and whole grains while also limiting processed foods and saturated fats.

This will help you stay on track while fasting, and it will also help you lose weight more consistently overall.

3. Exercise regularly

Another key component of fasting for weight loss is exercise. Not only does exercise help burn calories, but it can also help improve your mood and energy levels.

In addition, regular exercise can boost your metabolism so that you burn more calories even after you’ve stopped fasting.

What to eat while fasting for weight loss

The foods to eat while fasting for weight loss include:

1. Fruits and vegetables: A variety of fruits and vegetables are a great source of vitamins, minerals, and antioxidants, which can help promote weight loss.

2. Lean protein: A good source of lean protein can help keep you feeling full while you are fasting, helping to promote weight loss.

3. Low-fat dairy products: Low-fat dairy products contain calcium and other nutrients that can help support your weight loss efforts.

4. Whole grains: Whole grains are a good source of fiber, which can help to reduce the amount of calories that you eat.

5. Low-sugar snacks: Snacks that are low in sugar can help to reduce the amount of calories that you eat.

6. Fat-free beverages: Including fat-free beverages in your diet can help to reduce the amount of calories that you eat.

The Pros and Cons of fasting for weight loss

There are a few pros and cons to fasting for weight loss.


1. Fasting can help you lose weight by helping you burn more calories.

2. Additionally, fasting can improve your overall health by helping you cleanse your body and boost your immune system.


1. First, fasting can be difficult to do over a long period of time.

2. It can also be difficult to stick to a strict fasting schedule, which can lead to weight regain if you discontinue fasting.

3. Additionally, fasting may not be the best option for everyone. Some people may find that it’s too restrictive and uncomfortable to fast every day.


If you’re looking to lose weight, fasting may be a good way to start.

The metabolic process during fasting is different than when we are eating. When we eat, the body breaks down food and burns off calories.

But with fasting, the body gets energy from stored fat instead of from food. This means that your body will burn more calories while you’re fasting and help you lose weight.

However, there are some things to keep in mind before embarking on a fast diet:

1. Make sure to talk to your doctor first about whether or not fasting is right for you.

2. Follow the guidelines strictly so that you don’t end up gaining any weight back afterwards.

3. Enjoy your healthy foods while fasting!
