What Is Clean Or Dirty Fasting

Surprisingly, you can follow a clean fasting schedule or play it out a little bit dirty.

These terms refer to defining what kind of foods break the fast. The clean path defines a zero-calorie approach: you cannot drink or eat anything other than water, plain black coffee, green tea, or any type of herbal tea.

While dirty fasting, you might consume drinks that contain less than 50 calories, such as lemon water, coffee with MCT oil, bone broth, or zero-calorie drinks. You might even enjoy a piece of gum or an occasional mint.

Both of these methods are valid. As a beginner, you might want to start fasting dirty and go clean once you get a handle on your new routine.

To maximize the potential health benefits of your diet, its important to stick to nutritious whole foods and beverages during your eating periods.

Filling up on nutrient-rich foods helps round out your diet and supports a healthy weight. Try balancing each meal with a wide variety of whole foods, such as:

  • Fruits: apples, bananas, berries, oranges, peaches, pears, tomatoes, etc.
  • Veggies: broccoli, Brussels sprouts, cauliflower, cucumbers, leafy greens, etc.
  • Whole grains: barley, buckwheat, quinoa, rice, oats, etc.
  • Healthy fats: olive oil and avocados
  • Protein sources: eggs, fish, legumes, meat, poultry, nuts, seeds, etc.

Drinking calorie-free beverages like water and unsweetened tea and coffee, even while fasting, also helps control your appetite while keeping you hydrated.

Its best to avoid ultra-processed foods like packaged snacks, deep-fried items, sugary drinks, and most frozen meals. These negate the positive effects of 16/8 intermittent fasting and may harm your health.


To begin 16/8 intermittent fasting, choose an 8-hour window and limit your food intake to that time span. Be sure to follow a balanced diet based in whole foods.


Animal and human studies suggest that intermittent fasting may increase weight loss, improve blood sugar levels, and extend longevity.

The Ketogenic Diet Keeps You Satisfied


Another great perk of the keto diet is its high level of satiety.

Not only does ketosis itself tend to stifle hunger, but the high level of healthy fat in the keto diet also makes it much easier to stay satisfied in a fasted state and eliminates those intense feelings of hunger and cravings throughout the day.

This is perfect for someone doing intermittent fasting.

How Does Intermittent Fasting Work

There are many different intermittent fasting schedules.

Mattson says that after hours without food, the body exhausts its sugar stores and starts burning fat. He refers to this as metabolic switching.

Intermittent fasting contrasts with the normal eating pattern for most Americans, who eat throughout their waking hours, Mattson says. If someone is eating three meals a day, plus snacks, and theyre not exercising, then every time they eat, theyre running on those calories and not burning their fat stores.

Intermittent fasting works by prolonging the period when your body has burned through the calories consumed during your last meal and begins burning fat.

Hour Fast Benefit #: Improved Cognition

Pin on intermittent fasting

Studies show that intermittent fasting boosts several hormones, notably Brain-Derived Neurotrophic Factor , that are neuroplastic and neurodegenerative in nature.

In other words, fasting provides the perfect fuel for your brain. Increased BDNF levels are associated with improved mood, cognition, productivity, memory, and creativity. Harvard neuropsychiatrist John J. Ratey calls BDNF Miracle-Gro for the brain.

Its not known why intermittent fasting boosts BDNF so powerfully, but our evolution may give us some hints.

Throughout human history most tribes and people groups wouldve gone long stretches without food, say before their next successful hunt. During this time, peak physical and mental performance wouldve been paramount to securing the next meal and the body wouldve met this need.

To this day its thought that the human body perceives fasting as a healthy stressor and responds by forming new neurons that prime your body to learn new skills. In this type of emergency situation, BDNF allows our brains to form new neural networks quickly.

Q1: What about kickstarting your metabolism?

Well, unless your scooter is called Metabolism, you dont have to kickstart anything. It is probably true that breakfast used to be the most important meal.

But when it comes to the actual need of calories before lunch time , history has changed. Breakfast was considered the most important meal of the day when hard physical labour was the norm in most occupations. Now, due to how little physically demanding modern day labour has become, that logic no longer applies. It is also commonly believed you need breakfast to kickstart your metabolism. It is true that our metabolism will increase, not start, during periods of digestion. However, the peak is relative to the number of calories eaten. Thereby, your metabolism during 24 hours is affected by how many calories you eat, not when. Q2: Will intermittent fasting automatically result in fat loss? Fasting has no magic weight loss properties, other than helping you in a calorie deficit. Meaning, even if you implement fasting but are still eating too many calories you wont lose weight.

In a 2015 systematic review of intermittent fasting researchthe largest study on the topic to date compared the effects of intermittent energy restriction to continuous energy restriction on body weight and body composition.

The result? Both diet styles resulted in the same outcomes. Q3: What about morning / night workouts?

Forms of intermittent fasting like the 16:8 diet rely on the concept that fasting reduces oxidative stress on the body, which can decrease inflammation and the risk of chronic diseases.

Its also theorized that fasting gives your vital organs, digestive and absorptive hormones, and metabolic functions a break, according to a recent study published in Cell Metabolism. Since our bodies secrete insulin to help our cells absorb sugar, fasting is linked to reducing our susceptibility to insulin resistance over time.

However, research has also linked fasting to increases in LDL cholesterol . Intermittent fasting can make you feel dizzy and nauseated and cause periods of low-blood sugar and dehydration. Despite the fact that most 16:8 enthusiasts drink water during fasting periods, it may not be enough .

I also have a much deeper concern about the disordered eating behaviors that may arise from intermittent fasting. Research shows that fasting for a period of time followed by a limited window for eating primes you to overeat.
