A Guide to How Many Calories to Eat During Intermittent Fasting 16/8

Intermittent fasting (IF) is becoming popular among dieters and health fanatics all over the world and for good reason. It is one of those fad diets doctors say "that actually works." There are many ways to fast on the IF regimen, but one of the most common fasting methods is the 16/8 fasting protocol, which involves fasting for 16 hours and restricting your eating to an 8-hour window.

But what about calorie consumption during this fasting period? How many calories to eat during intermittent fasting 16/8 to achieve your health and weight goals? In this comprehensive guide, we'll explore the key factors to consider when determining your calorie intake during a 16/8 intermittent fasting regimen.

Determine Your Daily Caloric Needs

Everyone is going to have different caloric needs based on a wide variety of factors. There's no way to give one calorie intake number to everyone who is doing intermittent fasting. Some things to keep in mind are:

Basal Metabolic Rate (BMR): This is the number of calories your body needs to perform basic functions while at rest. Factors like age, gender, weight, and height influence your BMR.

Activity Level: Your level of physical activity plays a significant role in calorie expenditure. Active individuals require more calories to maintain their weight.

Goals

Whether you want to lose, maintain, or gain weight will also determine your caloric needs. Weight loss requires a calorie deficit, while weight maintenance and gain requires a surplus.

To get an estimate of your daily caloric needs, you can use an online calculator that takes these factors into account. Once you have an approximate daily calorie requirement, you can use it as a reference point for your 16/8 intermittent fasting plan.

Adjusting Calorie Intake During the Eating Window

During the 8-hour eating window, your goal is to meet your daily calorie requirements while adhering to your health and weight management objectives. Here's how to determine your calorie intake during this time.

Weight Maintenance

If your goal is to maintain your current weight, you should consume your estimated daily calorie needs during the 8-hour eating window. Ensure you include a balance of macronutrients (carbohydrates, proteins, and fats) to meet your dietary requirements.

Weight Loss

If you're aiming to lose weight, you'll need to create a calorie deficit. A common approach is to consume 70-80% of your daily calorie needs during the 8-hour eating window.

This deficit encourages your body to burn stored fat for energy. However, it's essential to maintain a healthy and sustainable calorie intake. Extreme calorie restriction is not recommended and can be detrimental to your health.

Weight Gain

For those looking to gain weight or build muscle, you'll need a calorie surplus. Aim to consume 110-120% of your daily caloric needs during the eating window.

This surplus provides the extra energy required for muscle growth and overall weight gain. Combine this with a well-balanced diet rich in protein and healthy fats.

Monitor Portion Size and Nutrient Quality

Regardless of your goal, portion control and the quality of nutrients you consume are paramount. It's essential to prioritize nutrient-dense foods that provide essential vitamins, minerals, and antioxidants.

Here are some additional tips for managing calorie intake during the 8-hour eating window:

Focus on Whole Foods: Incorporate fruits, vegetables, whole grains, lean proteins, and healthy fats into your meals to maximize nutrient intake. Minimize the consumption of highly processed and high-calorie, low-nutrient foods, which can lead to excessive calorie intake.

Use Smaller Plates: Serving your meals on smaller plates can help control portion sizes and prevent overeating. Study after study has shown that the bigger your plate, the more you will end up eating.

Practice Mindful Eating: Pay attention to your body's hunger and fullness cues. Eat slowly, savor your food, and stop when you feel satisfied. Try not to eat your meals while you are watching television or reading a book. It distracts you from your meal and you don't realize how much more you end up eating.

Stay Hydrated: Drink water throughout the day to help control appetite and prevent dehydration during the fasting period. Most people are walking around dehydrated and don't even know it. It's easy enough to carry a reusable bottle around with you and take a sip every few minutes even if you aren't thirsty. Remember, by the time you get the thirst signal, you are already dehydrated.

Adjust to Your Individual Needs: While these guidelines provide a general framework, it's essential to tailor your calorie intake to your specific needs and preferences. Everyone's body is unique. Individual factors such as metabolism, activity level, and health goals can influence how many calories you should eat during the 8-hour eating window.

If you ever start feeling weak or unwell while on the IF diet, then you need to stop immediately. Don't push yourself further than you need to. As with any diet plan, it is crucial to consult with a healthcare professional or registered dietitian before starting intermittent fasting, especially if you have underlying health conditions or specific dietary requirements.
