Intermittent Fasting: A Beginner’s Guide and Meal Plan

Intermittent fasting (IF), as defined by Sumona Mandal from University College London, refers to a dietary practice that alternates between periods of eating and fasting, commonly using time-restricted patterns like a 16-hour fasting window followed by an 8-hour eating window. Emerging evidence suggests benefits beyond weight loss, such as improved metabolic health and reduced systemic inflammation. The practice has ancient roots in various religious, cultural, and spiritual traditions, and it has gained modern popularity for its potential health benefits.

Intermittent fasting comes in several main types, each with its own set of rules and benefits. Time-restricted eating (TRE) involves a 16-hour fasting window followed by an 8-hour eating period, commonly known as the 16/8 method. Alternate Day Fasting (ADF) consists of switching between days of normal eating and days of complete fasting, while Modified Alternate Day Fasting (mADF) is a less stringent version that allows up to 40% of daily caloric intake on fasting days.

One of the primary benefits of these intermittent fasting methods is improved metabolic health, which includes better insulin sensitivity and reduced systemic inflammation. However, the main drawback is the difficulty in sticking to the diet, especially in social or family settings where communal eating is the norm.

This dietary approach is recommended for people aiming to improve metabolic health, lose weight, or simply explore a new way of eating. However, it’s not advisable for everyone, especially those with certain medical conditions or unique nutritional needs. Notable figures like Hugh Jackman, Terry Crews, LeBron James, and Jack Dorsey have publicly endorsed various forms of intermittent fasting, attesting to its growing popularity and potential benefits.

What is Intermittent Fasting?

Intermittent fasting is an eating pattern that alternates between periods of fasting and eating, often employing methods such as alternate-day fasting (ADF), the 5:2 diet, one meal a day (OMAD), or time-restricted eating (TRE). According to a 2021 study by Krista A. Varady from the University of Illinois at Chicago, these intermittent fasting methods can result in mild to moderate weight loss, ranging from 1-8% from baseline, and consistent reductions in energy intake of 10-30%. The study also highlighted that intermittent fasting is generally safe, without causing energy level disturbances or increased disordered eating behaviors.

A 2023 study by Hani Shalabi from the University of Jeddah further supported the efficacy of intermittent fasting, particularly for obese individuals aiming for weight loss, with minimal side effects like headaches, lethargy, and mood swings. Both studies indicate that intermittent fasting can be an effective and generally safe dietary strategy for weight loss and improved metabolic health.

What are the effects of Intermittent Fasting on women?

Intermittent fasting has been shown to decrease testosterone and free androgen index levels, while increasing sex hormone-binding globulin in obese premenopausal females, according to a 2022 study by Sofia Cienfuegos from the University of Illinois at Chicago. In this video, Dr. Jason Fung and special guest Megan Ramos discuss gender differences in fasting and offer three tips for women.

How does the Intermittent Fasting work?

Intermittent fasting works by restricting the time in which you can eat, leading to a decrease in overall calorie intake. This method of fasting allows your body to burn stored fat for energy, resulting in weight loss and promoting ketosis. Additionally, intermittent fasting has been shown to improve glycemic control and insulin sensitivity in individuals with type 2 diabetes. However, more long-term research is needed to fully understand the sustainable role of intermittent fasting in weight loss and overall health.

When asking about how intermittent fasting works for depression, we can reference a 2021 study by Elisa Berthelot from Aix-Marseille University. This study suggests that intermittent fasting may have potential benefits for treating depression, even though the exact mechanisms are not yet fully understood. The research indicates that intermittent fasting can improve mood and alleviate symptoms of depression, potentially due to metabolic changes such as increased ketone production and reduced inflammation.

How does Intermittent Fasting induce ketosis?

Intermittent fasting induces ketosis by restricting the availability of dietary carbohydrates, leading to a depletion of glycogen stores in the liver. Without an adequate supply of carbohydrates for energy, the body shifts to using stored fat as its primary fuel source. This metabolic adaptation promotes the production of ketone bodies, which are used by the body and brain as an alternative energy source during periods of fasting.

What are the health benefits of Intermittent Fasting?

The health benefits of intermittent fasting include improved weight loss, improved insulin sensitivity, reduced inflammation, improved cardiovascular health, increased autophagy, improved brain health, decreased oxidative stress, and extended lifespan.

intermittent fasting benefits
What are the health benefits of Intermittent Fasting?
  1. Improved Weight Loss: According to a systematic review by Stephanie Welton and colleagues from the Northern Ontario School of Medicine, published up to July 1, 2019, intermittent fasting shows promise in treating obesity. The review, which included 41 articles describing 27 trials, found that all intermittent fasting trials resulted in weight loss ranging from 0.8% to 13.0% of baseline weight, with no serious adverse events reported.
  2. Enhanced insulin sensitivity: According to a 2019 study by Yongin Cho from Inha University School of Medicine, intermittent fasting diets (IFD) were found to significantly improve insulin sensitivity, glucose regulation, and other glucometabolic parameters. The study concluded that IFD led to notable decreases in body mass index (BMI), fasting glucose levels, and insulin resistance, thereby reducing the risk of type 2 diabetes.
  3. Reduced inflammation: As per a 2020 meta-analysis led by Xiaoli Wang from the Tongde Hospital of Zhejiang Province, intermittent fasting has been shown to significantly reduce C-reactive protein (CRP) concentrations, a key marker of inflammation. This reduction was particularly notable in overweight and obese individuals and in interventions lasting eight weeks or more. However, the study found that intermittent fasting did not significantly affect other inflammatory markers like tumor necrosis factor-α and interleukin-6.
  4. Improved cardiovascular health: According to a 2021 meta-analysis by Mohammed Allaf and colleagues from Imperial College London, intermittent fasting was found to be superior to ad libitum feeding in reducing weight, although the clinical significance was not substantial. The study also revealed that intermittent fasting did not show a significant clinical difference compared to continuous energy restriction in improving cardiometabolic risk factors to reduce the risk of cardiovascular disease.
  5. Increased autophagy: A 2023 review by Roya Shabkhizan and colleagues from Tabriz University of Medical Sciences found that intermittent fasting or calorie restriction can induce adaptive autophagy, increasing the longevity of eukaryotic cells. The study suggests that while short-term calorie restriction promotes beneficial autophagic responses, prolonged calorie restriction with excessive autophagy can be harmful and may lead to type II autophagic cell death.
  6. Improved brain health: In a 2023 study by Zhao Liu and colleagues from Chongqing General Hospital and Chongqing Key Laboratory of Neurodegenerative Diseases, intermittent fasting was found to have neuroprotective effects and improve long-term brain health, particularly in the context of cerebral ischemia in rats.
  7. Decreased oxidative stress: In a 2015 study by Martin P. Wegman and colleagues from the University of Florida College of Medicine, intermittent fasting was explored for its effects on oxidative stress and genes related to aging. The study, which involved healthy individuals following a modified intermittent fasting diet, found that intermittent fasting marginally increased the expression of SIRT3, a gene associated with aging, by 2.7% and decreased plasma insulin levels.
  8. Extended lifespan: In a study by Valter D. Longo and colleagues from the University of Southern California, intermittent fasting lasting from 12 to 48 hours and repeated every 1 to 7 days has the potential to prevent and treat disease while affecting cellular aging. The research also discusses how these fasting methods are linked to major nutrient-sensing signaling pathways and focuses on the benefits and side effects of fasting in relation to various diseases, including cancer, autoimmunity, and neurodegeneration.

How effective is Intermittent Fasting for weight loss?

The effectiveness of intermittent fasting for weight loss is inconclusive, with some studies showing no significant benefits and others indicating clinically meaningful weight loss. In a 2023 meta-analysis led by Giovanni Antonio Silverii from Florence University and other researchers from Careggi Hospital in Italy, which analyzed 9 randomized controlled trials involving 540 patients, found that intermittent fasting did not show a significantly greater reduction in body weight or BMI compared to control diets or continuously restricted diets.

On the contrary, in a 2022 review published in Nature Reviews Endocrinology, Krista A. Varady and colleagues from the University of Illinois at Chicago noted that intermittent fasting diets have gained significant popularity for their ability to produce clinically meaningful weight loss. The paper summarized preliminary findings on the health benefits of intermittent fasting, specifically focusing on its effects on body weight and risk factors for cardiometabolic diseases, while also assessing the safety of these diets and offering practical advice for implementation.

Is intermittent fasting effective for diabetes management?

Yes, intermittent fasting shows potential as an effective strategy for diabetes management by improving weight loss, insulin sensitivity, and metabolic markers. However, according to a 2021 study by Michael Albosta from Central Michigan University College of Medicine, more research is needed to fully understand its effects and to determine the best approach for implementing intermittent fasting in diabetes treatment.

  11. Two Meals A Day (TMAD)
  12. Alternate-Day Fasting (ADF)
  13. 36-Hour Fast
  14. 48-Hour Fast

16:8 Intermittent Fasting

In the 16:8 intermittent fasting method, also known as leangains diet, you fast for 16 hours and limit your eating to an 8-hour window each day. This is one of the easiest fasting methods to follow, and it aligns well with a typical daily routine, making it sustainable. Some people find it hard to consume enough nutrients within the 8-hour eating window, and social or family gatherings may fall outside of the designated eating times.

18:6 Intermittent Fasting

In the 18:6 intermittent fasting method, you fast for 18 hours and eat within a 6-hour window each day. This method may offer greater weight loss and blood sugar control benefits due to the longer fasting period. However, the limited 6-hour eating window could make it difficult to meet nutritional needs and may interfere with social activities involving food.

20:4 Intermittent Fasting

In the 20:4 intermittent fasting method, you fast for 20 hours and eat during a 4-hour window. The long fasting period can yield significant metabolic benefits. However, the short 4-hour eating window may not provide sufficient time to meet nutritional needs.

The Warrior Diet

In the Warrior Diet, similarly to the 20:4 intermittent fasting method, you fast for 20 hours and eat a large meal during a 4-hour window, focusing on whole foods. The focus on whole foods can improve overall nutrition, and the extended fasting period may offer metabolic benefits. However, the limited eating window can make it difficult to meet all nutritional needs.

12:12 Intermittent Fasting

In the 12:12 intermittent fasting method, you fast for 12 hours and eat during the remaining 12 hours of the day. This is the least restrictive method, making it easy to adopt and maintain. However, the benefits may be less pronounced compared to other, more restrictive intermittent fasting methods.

5:2 Diet

In the 5:2 diet, you eat normally for five days of the week and reduce your calorie intake to around 500-600 calories on the remaining two days. This method offers flexibility and allows for more normal eating patterns on non-fasting days. However, the extreme calorie reduction on fasting days can lead to hunger, irritability, and reduced energy levels.


In the Eat-Stop-Eat method, you fast for a full 24 hours once or twice a week. This method offers significant calorie reduction, potentially leading to quicker weight loss. However, a full day without eating can be very challenging and may cause extreme hunger and fatigue.

Random Meal Skipping

In the Random Meal Skipping method, you skip meals spontaneously, without a set schedule. This offers the most flexibility and can easily be adapted to different lifestyles. However, the lack of a set schedule could make it hard to track caloric and nutrient intake.

Fasting Mimicking Diet (FMD)

In the Fasting Mimicking Diet, you consume very limited calories for five consecutive days per month to mimic the effects of fasting. This method aims to offer the benefits of fasting without completely abstaining from food. However, it may be difficult to adhere to due to the complexity and strictness of the diet plan.

One Meal a Day (OMAD)

In the One Meal a Day method, also known as the OMAD diet, you fast for 23 hours and eat one large meal in a 1-hour eating window. This method is simple to follow and can lead to significant calorie reduction. However, consuming all daily nutrients in one meal can be challenging, and this extreme approach isn’t suitable for everyone.

Two Meals A Day (TMAD)

In the Two Meals A Day method, also known as TMAD, you eat two meals a day with fasting intervals in between. This method offers a balance between fasting and eating, making it easier to meet nutritional needs. However, some people may find it challenging to only eat twice a day, leading to potential overeating during meal times.

Alternate-Day Fasting (ADF)

In Alternate-Day Fasting, you alternate between days of regular eating and days of fasting. This approach can yield significant weight loss and improvements in metabolic health. However, the frequent shift between eating and fasting can be hard to maintain and may cause mood swings.

36-Hour Fast

In the 36-hour fast method, you fast for a full 36 hours, typically once a week. The extended fasting period could lead to significant weight loss and metabolic benefits. However, going a day and a half without food can be extremely challenging and may result in severe hunger and fatigue.

48-Hour Fast

In the 48-hour fast method, you abstain from eating for two full days, usually done less frequently, like once a month. This method offers the potential for significant calorie reduction and weight loss. However, it’s a very extreme form of fasting that could lead to nutrient deficiencies and is not recommended for everyone.

What is the best intermittent fasting method for losing belly fat?

Time-restricted feeding (TRF) with a feeding window of 4–12 hours is the most practical intermittent fasting method for losing belly fat, as it is effective in reducing body weight and waist circumference. However, individual results may vary, and it’s advisable to consult a nutrition coach or dietician for personalized guidance.

How long does it take for the 16/8 intermittent fasting method to show results?

It is difficult to determine the exact time it takes for the 16/8 intermittent fasting method to show results. However, some studies have shown weight loss ranging from 0.8% to 13.0% of baseline weight after participating in intermittent fasting for a period of 2 to 26 weeks.

What results have people reported from intermittent fasting?

People have reported various results from intermittent fasting. While weight loss and improved sleep are common goals, some individuals have experienced significant improvements in their athletic performance, such as cycling. These improvements include faster times on personal bests and increased fitness levels, even without changes in training or equipment.

What are some success stories from intermittent fasting?

Some success stories from intermittent fasting include improved physical performance, faster personal best times, and increased energy levels. While individual results may vary, many people have reported positive effects on their weight management and overall health. It’s important to note that intermittent fasting should be approached with a balanced and healthy lifestyle.

Who are some famous people who follow intermittent fasting?

Five famous people who follow intermittent fasting are Hugh Jackman, Kourtney Kardashian, Jennifer Aniston, Jimmy Kimmel, and Halle Berry.

Is intermittent fasting considered healthy by medical professionals?

Yes, Intermittent fasting is considered a potentially healthy approach to weight loss by medical professionals, as it has shown promise in studies for promoting weight loss and improving glycemic control in patients with type 2 diabetes. However, more long-term research is needed to fully understand its sustainability and overall health effects.

What makes Intermittent Fasting different from other diets?

Intermittent fasting differs from other diets primarily in its focus on when to eat rather than what to eat. Traditional diets often involve calorie counting, food restrictions, or macronutrient balancing, whereas intermittent fasting cycles between periods of eating and fasting. This approach allows for more flexibility in food choices during eating windows and emphasizes metabolic health benefits like improved insulin sensitivity.
