30 Days Weight Loss Results on Intermittent Fasting: Here’s What to Expect

Intermittent fasting (IF) is one way to restrict your calorie intake for weight loss. While this approach doesn’t dictate what you eat, it certainly outlines when you should eat. You’re required to stick to a specific eating window, which has the potential to reduce your calorie intake.

There is a lack of long-term studies on the effectiveness of intermittent fasting for weight loss.  However, shorter studies have shown promising results in terms of weight loss and other potential health benefits. IF may actually be just as effective as traditional dieting for many people (4).

You may be wondering how soon you can see results if you start intermittent fasting and what changes can you expect in your body after 30 days of following this eating pattern. Let’s find out.

How Much Weight Can I Lose in 30 Days of Intermittent Fasting?

Most health authorities recommend aiming to lose 1-2 pounds a week, which is considered healthy and sustainable (8). As most months are a little over 4 weeks, you can expect to lose around 4-8 pounds in a month with intermittent fasting or any other weight loss strategy.

However, this can vary depending on your starting weight, chosen fasting schedule, food choices during the eating window, adherence to the fasting schedule, and activity level.

Here’s a closer look at why your 30-day weight loss intermittent fasting results may vary:

Starting Weight

The more weight you have to lose, the more likely you are to see significant changes in your body during the first 30 days. This is because when you have a higher amount of excess fat, it’s easier for your body to burn that stored energy than for someone who has less stored fat. 

Therefore, if you have a lot of weight to lose, you may see a bigger difference on the scale after 30 days of intermittent fasting. At the same time, if you’re already close to your ideal weight, it may be more challenging to see drastic changes in just one month.

Fasting Schedule

The length of your fasting window can also impact your weight loss results. Some people follow a 16:8 schedule (fast for 16 hours and eat within an 8-hour window), while others may opt for a more rigorous approach such as alternate day fasting or the 5:2 method (fasting for 2 days and eating normally for 5 days). 

Generally, the longer your fasting window, the more likely you will be to lose weight. However, it’s important to choose a schedule that is sustainable and healthy for your body. You need to reduce your overall calorie intake to lose weight, so whatever schedule helps you most easily do that without interfering with your life will likely work for you.

Food Choices

Intermittent fasting doesn’t dictate what you eat during your eating window, but it’s still important to make healthy food choices for optimal weight loss results. 

Consuming a balanced diet with plenty of fruits, vegetables, lean protein, whole grains, and healthy fats will help with weight loss and provide essential nutrients for overall health (6). 

At the same time, indulging in highly processed and calorie-dense foods during the eating window can hinder weight loss results.

Adherence to Schedule

Consistency is key when it comes to intermittent fasting. Skipping or cheating on fasting days can disrupt your progress and delay weight loss results. It’s important to remain committed to your chosen schedule for best results.

Activity Level

Regular physical activity is essential for weight loss, and it plays a significant role when paired with intermittent fasting. Engaging in moderate to vigorous exercise during the eating window can boost your metabolism and help with weight loss (7).

In addition, higher activity levels can lead to muscle gain, which can affect your overall body composition, although this may not be reflected on the scale.

What Happens to the Body After 30 Days of Intermittent Fasting?

In the first few days of intermittent fasting, you may experience some hunger and cravings as your body adjusts to the new eating pattern. This is completely normal and can be managed by staying hydrated and distracting yourself with other activities. 

You may also feel more tired or have difficulty concentrating as your body adapts to using stored fat for energy instead of glucose. This is known as the “keto flu” and should go away after a week or so. If your symptoms are persistent and/or affect your quality of life, you should stop fasting immediately and talk to your healthcare provider.

After 30 days, a number of changes may occur in your body as a result of intermittent fasting, including:

Reduction in Body Fat

Intermittent fasting helps to create a caloric deficit, contributing to weight loss and a decrease in body fat percentage. This is because alternating between periods of eating and fasting typically results in eating fewer calories overall (4).

That said, it isn’t automatic and still depends on your overall calorie intake during the eating window.  Some reasons why you may not experience significant weight loss after 30 days of intermittent fasting include:

• Consuming too many calories during the eating window – if you’re overcompensating for fasting by consuming more food, you may not be in a calorie deficit after all. Without a calorie deficit, weight loss won’t occur.
• Choosing unhealthy, high-calorie foods during the eating window – Eating mostly high-calorie food during your eating window can sabotage your weight loss efforts (2). You may experience cravings, overeat, and not see any significant changes in your weight.
• Not being consistent with intermittent fasting – skipping days or not sticking to the designated eating window can also hinder weight loss results.
• Underlying medical conditions – Certain medical conditions can make losing weight difficult, even when you’re following a strict eating pattern such as intermittent fasting. You should consult your doctor if you have concerns about your weight loss progress.

Increase in Lean Muscle Mass

Due to its potential to preserve muscle mass, intermittent fasting may also lead to an increase in lean muscle mass. It is possible that your body will produce more human growth hormone (HGH), which plays a role in muscle maintenance and growth, during the fasting period (3). 

In addition, engaging in regular exercise, particularly resistance training, during the eating window can also contribute to muscle gain.

It’s not easy to tell whether you’ve gained muscle mass simply by looking at the scale, which is why it’s important to focus on other progress markers such as how your clothes fit and body measurements.

Increased Energy

It may seem counterintuitive, but many people report feeling more energized and focused after a few weeks of intermittent fasting. This could be due to metabolic improvements that are associated with weight loss, or simply a subjective experience (1).

Is It Safe to Fast for 30 Days?

A 30-day fast is dangerous and downright unhealthy. Prolonged fasting such as this can lead to many health complications, including:

• Nutrient deficiencies – Fasting for extended periods can lead to nutrient deficiencies, as your body is not getting the necessary vitamins and minerals it needs.
• Muscle loss – Going without food for a prolonged period can lead to muscle loss, which affects physical appearance and overall strength and mobility.
• Dehydration – Not consuming enough fluids during a fast can result in dehydration, leading to dizziness, fatigue, and other health issues.
• Compromised immune system – Prolonged fasting can weaken the immune system, which can make you more susceptible to illness and infections.
• Disordered eating patterns – Fasting for 30 days can also trigger disordered eating patterns and an unhealthy relationship with food.
• Overall health risks – Fasting for extended periods can increase the risk of other health complications such as heart disease, low blood pressure, and electrolyte imbalances. Some of these can be life-threatening. 

Rather than prolonged fasting, you should consider incorporating shorter periods of intermittent fasting into your routine. For example, try starting with a 16/8 schedule (fasting for 16 hours and consuming all meals within an 8-hour window) and gradually increase the fasting period if desired.

You should understand your body’s limits and consult a healthcare professional before you attempt any type of fasting. Remember, the goal of intermittent fasting is to promote a healthier lifestyle, not extreme weight loss or deprivation.

How to Lose 30kg with Intermittent Fasting

The best way to lose 30 kg with IF is gradually (starting with smaller goals) and sustainably (by incorporating healthy eating habits and regular exercise). Here are some tips to help you on your weight loss journey:

• Start with a realistic goal – Instead of setting a goal to lose 30 kg in 30 days, you should aim for sustainable weight loss of 0.5-1 kg per week.

• Focus on whole, nutrient-dense foods – It’s essential to prioritize nutrient-dense and low-calorie foods during your eating window to see significant weight loss results. This includes lean proteins, complex carbohydrates, healthy fats, and plenty of fruits and vegetables.
• Stay hydrated – Drinking enough water is vital for your overall health and can also help control hunger during the fasting period.
• Incorporate exercise – Regular physical activity is essential for weight loss and overall well-being. Try incorporating a mix of cardio and strength training into your routine to see the best results.
• Be patient and consistent – It’s important to remember that weight loss takes time, and it’s important to be patient and consistent with your efforts. Focus on progress rather than perfection.
