A Primer on Intermittent Fasting: Everything You Need to Start
Oct 08, 2023 By Nancy Miller

If you like to stay up-to-date with the fitness world trends, you must have heard about "intermittent fasting." Accompanied by impressive intermittent fasting before and after photos and testimonials, this dietary approach has garnered attention worldwide. Like all nutrition and health plans, it's important to understand the basic intermittent fasting rules before plunging in.

Intermittent Fasting

Traditional diets are not intermittent fasting (IF). Instead, it is an eating pattern. IF dictates when you eat, not necessarily what you eat. The idea is to cycle between periods of eating and fasting.

In essence, if you think about it, every one of us fasts daily during our sleep hours. Intermittent fasting can be as short or long as you choose within healthy limits.

Types of Intermittent Fasting

The diverse world of intermittent fasting can be a maze for newcomers. To navigate this world wisely, it's paramount to understand its varying strategies, each offering a distinct approach to the periods of eating and fasting. Here are some of the most popular methods:

16/8 Method (Leangains Protocol)

This technique, also known as the Leangains Protocol, entails abstaining from food for 16 hours straight and limiting eating to 8 hours.

This approach is lauded for its simplicity and ease of integration into daily routines. It's also been linked to enhanced fat loss and muscle gain when combined with resistance training.

Challenges: Some individuals might need more breakfast, mainly if they're used to a morning meal.

Typical Schedule: This may mean foregoing breakfast and eating all of one's meals between midday and eight in the evening. Those who aren't hungry first thing in the morning will likely follow this trend.

5:2 Diet (The Fast Diet)

In this strategy, five days of the week are treated as 'normal' eating days, while the remaining two days mandate a strict calorie limit of 500–600 calories. It allows flexibility on most days, which can be less intimidating for beginners. However, hunger can be more pronounced on low-calorie days, which might be difficult for some to adjust to.

Typical Schedule: You could choose Monday and Thursday as your low-calorie days, consuming just a light breakfast and dinner.


This entails a complete 24-hour fast, either once or twice a week. A 24-hour fasting window can induce a robust metabolic switch, promoting the use of fat stores for energy. However, enduring a day without meals is mentally and physically exhausting.

Typical Schedule: If you eat dinner at 7 p.m. on Tuesday, you'll eat again on Wednesday.

Alternate-Day Fasting

As the name suggests, you fast every other day. Some versions of this method allow about 500 calories during fasting days. This method is relatively straightforward – alternate between regular eating and fasting days.

On the brighter side, regular fasting days can lead to consistent calorie reduction. But, the frequent switch between eating and fasting might be challenging to adhere to in the long run.

Typical Schedule: Monday-Wednesday-Friday could be fasting days, with the rest being regular eating days.

Warrior Diet

This diet advocates for eating small amounts of raw fruits and vegetables during the day, followed by one large meal in the evening. The approach taps into our ancient eating patterns, aligning with how our warrior ancestors might have eaten. However, limited daytime eating might only sustain energy levels for some, especially those with demanding physical routines.

Typical Schedule: Snack on fruits and vegetables from morning to late afternoon, then enjoy dinner.

Each intermittent fasting method has its challenges and benefits—the best one for an individual hinges on personal preferences, lifestyles, and unique health conditions.

Intermittent Fasting Rules

Choose Your IF Method Carefully

Given the myriad methods, making an informed choice is pivotal and one of the major intermittent fasting rules. While the 16/8 method might seem palatable for novices due to its shorter fasting window, others might thrive on the rigorousness of the Eat-Stop-Eat approach.

Stay Hydrated

Regardless of the method, hydration is non-negotiable. While water should be your go-to, unsweetened herbal teas and black coffee (sans sugar or milk) are also acceptable during fasting windows.

Prioritize Nutrient-Dense Foods

Your eating windows should champion nutrient-rich foods, emphasizing whole grains, lean proteins, healthy fats, and a rainbow of fruits and vegetables. This ensures that even with reduced meal frequency, nutrient intake remains optimal.

Avoid Overexertion

While staying active complements intermittent fasting, overburdening oneself, especially during fasting periods, can be counterproductive. Opt for moderate exercises that suit your energy levels.

Listen to Your Body

Your body often knows best. If you're feeling excessively drained or hungry, it's a sign to reassess your fasting strategy. Sustainability should be at the heart of any IF approach.

Benefits of Intermittent Fasting

Weight Loss

This is the most flaunted benefit, and rightfully so. The combination of reduced meal frequency and altered hormone functionality often results in decreased calorie intake and increased fat utilization. Numerous intermittent fasting before and after narratives underscore this transformative journey.

Improved Metabolic Health

Beyond weight loss, IF boasts extensive metabolic advantages. By influencing various biomarkers, it reduces inflammation, optimizes cholesterol profiles, and stabilizes blood sugar levels, thus forming a formidable defense against chronic diseases.

Brain Health

The brain isn’t left behind, either. Fasting nudges the brain into producing more BDNF, a hormone critical for neuroplasticity and overall brain function. Preliminary studies even suggest a protective role against degenerative conditions like Alzheimer's.

Extended Longevity

While more research is warranted, especially in humans, the existing data from animal studies paints a promising picture. Regular fasting may reduce aging and provide a longer, healthier life.

Intermittent Fasting Meal Plan

An effective intermittent fasting meal plan will depend on the method chosen. However, for someone following the popular 16/8 method, here’s a sample meal plan:

Lunch (12:00 PM)

  • Grilled chicken salad with plenty of greens, tomatoes, cucumber, olives, and a vinaigrette dressing.
  • A serving of quinoa or brown rice.
  • A glass of lemon water or herbal tea.

Snack (3:00 PM)

  • A handful of almonds or walnuts.
  • Any fruit like banana or orange.

Dinner (7:00 PM)

  • Steamed broccoli, cauliflower, and carrots with grilled fish or tofu.
  • Chickpea salad or lentil soup.
  • A serving of whole grain, such as barley or farro.
  • Herbal tea or water.


Intermittent fasting has several health benefits and has helped people lose weight. The intriguing intermittent fasting before and after transformations certainly provides ample motivation. Follow your body, understand intermittent fasting, and choose a diet that fits your lifestyle and health demands, as with other diets. Doctors should be consulted before commencing new health routines.
