1. What are Calories? How to Determine Your Daily Caloric Needs?

Calories are a unit of measurement for the energy we receive from food and beverages. We use calories to sustain basic bodily functions such as respiration, cardiovascular activity, and movement. When we talk about a “1000 calories a day” diet, we’re referring to limiting daily caloric intake to just 1000 calories.

Each type of food contains a different amount of calories. According to experts, 1g of carbohydrates contains 4 calories, 1g of fat contains 9 calories, 1g of protein contains 4 calories, and 1g of alcohol contains 7 calories.

If the body receives enough calories each day, it will function normally. However, if you consume too many calories, you may encounter health issues such as weight gain, joint diseases, high blood pressure, respiratory and cardiovascular diseases. Conversely, if you do not receive enough calories, basic bodily functions can be affected, leading to fatigue, weakness, lack of focus, and decreased immunity.

So, how many calories does the body need each day for optimal health? The necessary daily calorie intake depends on several factors such as height, weight, age, and level of physical activity. The calculation for daily calorie intake (TDEE) is as follows:


In which: 

  • BMR is calories consumed..
    • For men, BMR = BMR = (13,397 x Weight) + (4,799 x Height) – (5,677 x Age) + 88,362.
    • For women, BMR = (9,247 x Weight) + (3,098 x Height) – (4,330 x Age) + 447,593.
  • R is the number of active calories per day.

If you lead a sedentary lifestyle (only eating, sleeping, and performing light office work), then your metabolic rate (R) is 1.2. If you engage in light physical activity (exercising 1-3 times per week), then R = 1.375. If you engage in moderate physical activity (3-5 times per week), then R = 1.55. If you engage in heavy physical activity (6-7 times per week, regularly participating in sports), then R = 1.725. If you engage in very heavy physical activity (manual labor, athletes training twice a day), then R = 1.9. 

Typically, adult women require approximately 1,500 calories per day, while men require around 1,800 calories per day. However, everyone has a different rate of energy expenditure and metabolism. Therefore, it is recommended that you consult with a nutrition expert to better understand your body’s mechanisms and plan a diet that suits your individual needs.

2. How Many Calories Should You Consume Daily for Weight Loss?

To effectively lose weight, experts recommend maintaining a calorie deficit, meaning the calories you consume daily should be less than the calories your body burns. For instance, once you’ve determined the necessary daily calorie intake for your body, you should reduce your calorie consumption by about 400 – 500 calories compared to that number. However, your calorie intake should not be reduced excessively to ensure your body still has enough energy to maintain basic activities such as respiration and cardiovascular function.

Weight loss should be carried out gradually and with a plan. If you lose weight too quickly, your body may burn muscle, bone, and water instead of excess fat. To lose weight healthily, you should participate in nutrition courses, learn about how to provide reasonable calories for the body, or seek advice from specialist doctors.

5. Frequently Asked Questions about the 1000 Calorie a Day Diet

Does a 1000 calories a day diet help with weight loss, and is it good for overall health? Here are some questions answered by a nutrition expert:

5.1 Can You Lose Weight by Consuming 1000 Calories a Day? 

Based on the BMR index, a woman typically needs about 1,500 calories per day, while a man needs around 1,800 calories. When you reduce your calorie intake to 1000 calories a day, you create a calorie deficit of 500 to 800 calories, which can aid in weight loss.

According to those who have tried it, the weight loss effects can be noticeable after a short period. If your body is prone to losing weight, you might lose 2 to 3 kg just after about 10 days. If you combine this with exercise, you could lose 4 to 5 kg.

However, remember that every body is different and the rate of weight loss will vary. This is just one method of weight loss and it may not be suitable for everyone. Before starting any diet, you should discuss it with a health expert or your doctor.

5.2 Is a 1000 Calorie a Day Diet Healthy? 

A 1000 calories a day diet can provide enough energy for the body’s basic activities. However, to ensure health, you need to focus on getting enough nutrients from food groups that are rich in protein, fiber, and vitamins. Additionally, combining this with exercise can help you lose weight more effectively and prevent diseases related to the cardiovascular system, blood pressure, and diabetes.

For men and those who regularly do heavy work, a 1000 calorie per day diet may not be suitable. In the initial stages, you may feel uncomfortable, hungry, and have cravings. Try to maintain this diet for about 7-10 days. Afterward, you can increase your calorie intake to 1,200-1,300 calories per day to maintain a stable weight. During the implementation of this diet, drink plenty of water, avoid alcohol and cigarettes to optimize weight loss effectiveness.
