Introduction: 800 Calories Per Day Diet

Starting an 800 calories per day diet can be a challenging yet rewarding journey. If you want to know what consuming 800 calories a day looks like, especially in your first week, you’re in the right place. This guide will provide you with detailed insights and practical tips on the Fast 800 diet.

Day 0: Preparation and Motivation

Like many, I indulged in emotional and stress eating during the strict lockdown period. However, it’s time to regain control. Investing in a good set of scales, which can connect to an app for tracking progress, can be a great motivator. Remember, the primary goal is not just weight loss but also overall well-being. Personally, I sleep better and have more energy when I maintain a healthier weight.

Day 1: The Beginning of the Fast 800 Diet

Starting the Fast 800 diet requires meticulous preparation. Begin by taking three measurements: your weight, waist circumference, and resting heart rate. These metrics will help you track your progress effectively. On the morning of Day 1, my weight was slightly less than the previous day, which was encouraging.

Adjusting to the Diet: Days 1 to 3

The first three days of the diet can be challenging as your body adjusts to the reduced calorie intake. Incorporate light exercise to help manage weight and maintain energy levels. Working from home can make it difficult to stay active, so aim to take morning walks to achieve at least 10,000 steps a day.

Supplements and Nutrition

While following the Fast 800 diet, consider taking supplements to ensure your body gets the necessary nutrients. My regimen includes vitamin D spray, a multivitamin, collagen, prebiotics, magnesium, and biotin. These supplements support overall health, especially when consuming a low-calorie diet.

Overcoming Challenges: Days 4 to 6

By Day 4, you might start feeling hungrier than usual. Staying hydrated by drinking plenty of water, tea, and black coffee can help manage hunger pangs. Despite the challenges, losing 2 kilograms in three days was a significant achievement. Remember, it’s important to stay focused and not give in to cravings.

Positive Changes: Day 6

By Day 6, you may notice positive changes, such as improved sleep quality. During the lockdown, I struggled with poor sleep due to my unhealthy diet. However, after six days on the Fast 800 diet, I was sleeping better and feeling more refreshed.

One Week In: Day 7 and Beyond

By the end of the first week, it’s normal to experience a plateau in weight loss. My intake averaged around 800 calories for five days and 1,000 calories for two days. The most satisfying result was losing 3 centimeters around my waist, a significant reduction in unhealthy fat.
