Nutritional Considerations

Intermittent fasting can have a significant impact on nutritional intake, and it is important to ensure that nutrient needs are being met during the periods of eating. I usually recommend a superfood drink mix, MCT oil, and a protein drink while on an intermittent fast. These supplements can also prevent overeating during the “eating phase” and ensure adequate nutrients are consumed.

Eat Nutrient-Dense Meals

Eating a nutrient-dense diet during intermittent fasting is essential for several reasons. When you fast, your body undergoes various metabolic changes, and during the eating window, it is crucial to provide your body with the necessary nutrients to support these processes and maintain overall health. A nutrient-dense diet is composed of foods that provide a high amount of vitamins, minerals, and other essential nutrients relative to their calorie content. Let’s discuss the science behind the importance of a nutrient-dense diet during intermittent fasting.

Preventing nutrient deficiencies

As intermittent fasting involves periods of restricted food intake, there’s an increased risk of nutrient deficiencies. A nutrient-dense diet helps ensure you’re meeting your daily nutrient requirements, which is essential for maintaining optimal health and preventing deficiencies that can impair metabolic processes and increase the risk of various diseases.

Maintaining muscle mass

Consuming adequate protein during the eating window is essential to preserve muscle mass, promote muscle growth and repair, and support overall physical performance.

Enhancing immune function

A nutrient-dense diet provides essential nutrients, like vitamins A, C, D, and E, and minerals like zinc and selenium, which support a healthy immune system and help protect against infections and diseases.

Supporting brain function

Nutrient-dense foods, such as those rich in omega-3 fatty acids, antioxidants, and B vitamins, support cognitive function, memory, and mood.

Promoting satiety and weight management

Nutrient-dense foods, such as those high in protein and fiber, can help promote satiety, prevent overeating, and support healthy weight management during intermittent fasting.

Adequate Hydration

Adequate hydration is essential during intermittent fasting for because it’s involved in numerous physiological processes.

Water is essential for maintaining the body’s fluid balance, which is vital for various functions such as digestion, circulation, temperature regulation, and nutrient transport. During fasting, fluid intake from food is reduced, making it even more important to ensure adequate water consumption.

Dehydration can cause various symptoms, such as dizziness, fatigue, headaches, and constipation. The brain is highly dependent on water for optimal functioning. Dehydration can negatively impact cognitive function, leading to problems with concentration, memory, and mood.

Water is involved in the breakdown of nutrients and the elimination of waste products. Proper hydration during fasting can help maintain efficient metabolism and facilitate the body’s natural detoxification processes. The kidneys play a crucial role in filtering waste products from the blood and regulating electrolyte balance. Adequate hydration is essential for proper kidney function and helping to prevent the buildup of waste products.


If you find that you need to snack during your feeding window, there are some tips that can help.

Choose healthy, nutrient-dense snacks

Opt for snacks that are high in protein, fiber, and healthy fats, such as nuts, seeds, hard-boiled eggs, veggies with hummus, or a small piece of fruit.

Avoid high-carb, high-sugar snacks

Snacks that are high in refined carbohydrates and sugar can lead to blood sugar spikes and crashes, which can disrupt your energy levels and hunger cues. Avoid snacks like candy, chips, or sugary drinks.

Plan ahead

Have healthy snacks prepared and easily accessible so that you’re not tempted to grab something unhealthy or break your fast with an unplanned snack.

Practice mindful eating

Take the time to savor your snacks and eat them slowly, paying attention to how they make you feel. This can help you tune in to your hunger cues and avoid overeating.
