The feast and famine cycle, also known as intermittent fasting or alternate-day fasting, is a dietary approach that alternates between periods of eating (feasting) and calorie restriction or complete fasting (famine). This method emulates the eating patterns of our hunter-gatherer ancestors, who experienced periods of food abundance followed by scarcity. The feast and famine cycle is considered by some to be the best diet to lose weight, as it forces the body to use stored fat as energy. This approach can also regulate insulin levels and reduce inflammation, both of which contribute to weight gain.
The Biological Basis of Feast and Famine
From a biological standpoint, humans haven't changed much since our hunter-gatherer days, so our bodies still have an instinctual desire to feast and famine. However, instead of experiencing periods of abundance followed by scarcity, we are blessed with a constant state of abundance. Unfortunately, we have an excess of highly processed and calorie-dense foods available. If not properly managed, consumption of these foods leads to weight gain and other health issues.
Understanding the Feast and Famine Cycle
The feast and famine cycle involves two distinct phases: the feasting phase and the famine phase.
The Feast
The feast part of the cycle refers to the period where you can eat normally without any restrictions. This usually lasts from 8-12 hours, depending on your personal preference and schedule. During this time, you can consume all your daily calorie needs and indulge in your favorite foods.
The Famine
The famine part of the cycle refers to the period where you restrict your calorie intake or completely fast for a set amount of time. This can range from 12-24 hours, depending on the type of fasting chosen. During this time, you are allowed to consume only a limited amount of calories, usually in the form of liquids such as water, tea, or coffee without sugar.

Intermittent Fasting: A Popular Form of Feast and Famine
Intermittent fasting is a form of the feast and famine diet that has become increasingly popular in recent years as a weight loss method. It involves cycling between periods of eating and fasting, with the most common schedule being 16 hours of fasting followed by an 8-hour eating window. Alternate-Day Fasting is another type of intermittent fasting diet that involves alternating between fasting and eating normally. On fasting days, solid food intake is restricted from somewhere between 0 and 25% of the typical caloric intake. On non-fasting days, individuals are allowed to eat as much as they wish. One of the main reasons for the increase in popularity is that most intermittent fasting programs don’t restrict what you eat, but rather when you eat. This can be appealing to many people who struggle with traditional diets that require cutting out certain foods or drastically reducing calorie intake.
How Intermittent Fasting Promotes Weight Loss
During the fasting period, your body exhausts its glucose (carbohydrate) stores and starts burning stored fat for energy. This process, known as ketosis, results in weight loss as your body breaks down fat cells. When our body is in ketosis, it becomes more efficient at using stored fat as energy. As a result, the body improves at breaking down and utilizing its fat stores for fuel. This is why the ketogenic diet has gained popularity as a weight loss tool.
Regulating Hunger Hormones with Intermittent Fasting
Intermittent fasting also helps to regulate hormone levels that play a role in hunger and satiety, such as insulin and ghrelin. This can lead to a decreased appetite and ultimately, fewer calories consumed. Insulin is a hormone produced by the pancreas that helps regulate blood sugar levels. When we eat, our bodies release insulin to help move glucose (sugar) from the bloodstream into our cells for energy. However, when we consistently consume high amounts of carbohydrates and sugars, our bodies can become resistant to insulin and require higher levels to be released in order to maintain stable blood sugar levels. This leads to overproduction of insulin, which causes an increase in fat storage and weight gain. Intermittent fasting helps regulate insulin levels by allowing the body to go longer periods without food, which gives the pancreas a break from constantly producing insulin. This helps improve insulin sensitivity, meaning our bodies become more efficient at using this hormone to manage blood sugar levels. As a result, our bodies require less insulin overall, leading to decreased fat storage and weight loss. In addition to regulating insulin, intermittent fasting also has an impact on the hormone ghrelin. Ghrelin is known as the “hunger hormone” because it stimulates appetite and increases food intake. When we fast for extended periods of time, ghrelin levels decrease, leading to reduced feelings of hunger. This makes it easier to stick to a calorie-controlled diet and avoid overeating. Moreover, intermittent fasting has been shown to increase the production of human growth hormone (HGH), which plays a role in metabolism and muscle growth. Higher levels of HGH have been linked to increased fat burning potential and improved body composition. Overall, intermittent fasting has a positive impact on hormone levels, leading to reduced appetite and improved metabolic health. This makes it easier to stick to a healthy diet and achieve weight loss goals.
Cardiovascular Benefits of Intermittent Fasting
Intermittent fasting has been found to reduce blood pressure levels. High blood pressure is a significant risk factor for heart disease and stroke, as it puts added strain on the heart and blood vessels. Studies have shown that intermittent fasting can lower both systolic and diastolic blood pressure, leading to a decrease in overall risk for cardiovascular disease. Intermittent fasting also helps reduce inflammation in the body. Chronic inflammation is linked to various chronic diseases, including cardiovascular disease. Studies have shown that intermittent fasting lowers levels of inflammatory markers in the body, reducing the risk of developing heart disease.
The Importance of Diet Variation
While there are numerous benefits to intermittent fasting, it is important to ensure that we are consuming enough calories during our feeding window. If we do not eat enough during the feeding period, we constantly remain in a catabolic state, where our body breaks down muscle tissue for energy. This is detrimental to our health over the long-term and cannot be sustained indefinitely. For true health, fasting has to coincide with feasting. Interchanging days of fasting with days of feasting, as well as varying the types of food we consume, is known as diet variation. One major pathway that is affected by diet variation is the mTor pathway. This cellular signaling pathway plays a crucial role in regulating cell growth, metabolism, and survival by acting as a sensor for nutrient availability and energy status in the body. During feasting, when there are plenty of nutrients available, mTor is activated, leading to cell growth and protein synthesis. However, during fasting, when nutrients are limited, mTor activity decreases. This decrease in mTor activity triggers a series of events that lead to a shift in our metabolism from using glucose for energy to using fat. This cycle of activation and inhibition of the mTor pathway during feasting and famine is essential for maintaining optimal metabolism and cellular health.

Common Diet Variation Schedules
The 5-1-1 diet is a popular diet variation method that consists of a weekly schedule of 5 intermittent fast days, 1 fast day, and 1 feast day. Other common weekly diet variations include the 4-2-1 (4 intermittent fast days, 2 fast days, and 1 feast day) and the 3-2-2 (3 intermittent fast days, 2 fast days, and 2 feast days).
The Benefits of Water Fasting
Water fasting, particularly for 3-5 days, has significant detoxifying benefits. By consuming only water, our body is given a break and can reset itself. This process not only cleanses the body but also promotes better digestion and gut health. Additionally, studies have shown that water fasts improve insulin sensitivity. This is because the body utilizes its fat stores for energy instead of relying on sugar consumption, leading to better blood sugar management. Water fasts also have profound effect on reducing inflammation in the body. A short break from eating allows our immune system to repair and regenerate, leading to a healthier body. However, it is important to note that water fasting should not be done continuously and must be accompanied by feasting days. This means that after completing a 5-day water fast, one must partake in sufficient feast days to replenish their body’s nutrients.
The Cellular Healing Diet: Optimizing Food Choices
Taking it a step further, successful weight loss is aided by consuming healthier food choices during the eating window. A balanced and nutritious diet like the Cellular Healing Diet focuses on the consumption of high-quality fats, moderate protein, and minimal carbohydrates. This aligns with our ancestor’s diets, which were primarily centered around nutrient-dense animal products. The pillars of a healthful diet include grass-fed meat, nutrient-rich bone broth, and organ meats. It is vital to choose animals that have been ethically raised naturally, as commercial farms typically use a cocktail of corn, grains, antibiotics, growth hormones, and other harmful chemicals in their livestock feed.
The Importance of Grass-Fed Meat
Grass-fed meat is a noteworthy source of protein, vitamins, minerals, and healthy fats. It is abundant in essential fatty acids like omega-3s and conjugated linoleic acid (CLA), nutrients deficient in grain-fed meats. Furthermore, grass-fed meat is far more nutritious than grain-fed varieties with its higher antioxidant, beta-carotene, iron, zinc, vitamin E, and B vitamin content. Associated health benefits include reduced inflammation, enhanced heart health, lower cholesterol levels, improved muscle mass, and better digestive health.
The Role of Fish in a Balanced Diet
Fish is another indispensable element of a balanced diet due to its rich concentration of omega-3 fatty acids EPA and DHA. These fatty acids are integral to brain function, cell membrane fluidity, and inflammation reduction. Oily fish such as salmon, mackerel, and sardines are especially beneficial due to their high DHA and EPA content. These have been extensively studied and found to decrease cognitive decline risk, enhance memory, and exhibit antidepressant properties.

Healthy Fats, Vegetables, and Optional Foods
Alongside animal products, healthy fats like olive oil and coconut oil are vital for maintaining cellular membrane health. Olive oil is filled with polyphenols, potent antioxidants that fight inflammation and safeguard against chronic diseases. Coconut oil, meanwhile, is brimming with lauric acid, possessing antiviral and antibacterial properties that aid the immune system. Non-starchy vegetables and organic leafy greens offer a wealth of essential vitamins, minerals, and dietary fiber. They provide vital antioxidants that mitigate inflammation and shield against free radicals. Nutrient-dense cruciferous vegetables like broccoli, cauliflower, and Brussels sprouts as well as dark leafy greens such as kale are particularly recommended for overall health. Although optional, incorporating certain foods in moderation can enhance dietary variety. These include beans, lentils, nuts, seeds, low-glycemic fruits, and dark chocolate. These nourishments provide supplemental nutrients, fiber, and healthy fats.
Transitioning to a Cellular Healing Diet
If you are not accustomed to eating a natural diet, initially start with a feast and famine diet of your liking. When you are ready, start incorporating foods from the Cellular Healing Diet to both lose weight and take your health to the next level.
Criticisms and Considerations
Despite the potential benefits, the feast and famine cycle, particularly in the form of alternate-day fasting, has faced criticism. A study in the American Journal of Clinical Nutrition monitored 16 subjects for 10 weeks and found that while dieters adhered to the diet for roughly 86 percent of the days and lost about one-and -a-half pounds a week, there were concerns. Dr. Jana Klauer, a Manhattan physician and research fellow at the New York Obesity Research Center at St. Luke's-Roosevelt Hospital, noted that the size and length of the study were both too small for anyone to draw a conclusion. She also worried that the lack of consideration given to medications and exercise in the study might have affected the results. Connie Diekman, director of university nutrition at Washington University in St. Louis, worried that the diet would lead to binging that would not ultimately lead to weight loss. Furthermore, a small study revealed that the alternate fasting day group had a significant elevation in low-density lipoprotein (LDL), an increase of 11.5 mg/dl as compared to the daily calorie restriction group. It's also worth noting that in this study, over time people in the fasting group ate more on fasting days and less on feasting days, and twelve people quit the alternate-day fasting group, with almost half citing dissatisfaction with the diet due to feeling uncomfortably hungry and irritable on fasting days.
Conclusion
The feast and famine cycle, encompassing intermittent fasting and diet variation, presents a compelling approach to weight loss and overall health improvement. By mimicking ancestral eating patterns and incorporating nutrient-dense foods like those found in the Cellular Healing Diet, individuals can potentially improve insulin sensitivity, reduce inflammation, and promote fat burning. However, it is crucial to approach this dietary strategy with caution, ensuring adequate calorie intake during feasting periods and considering individual health conditions. It is always advisable to consult with a healthcare professional or registered dietitian before embarking on any new dietary regimen.
