The calorie deficit diet works by reducing daily calorie intake from food below what the body needs. This makes the body use stored fat because it burns more calories than it takes in, which leads to weight loss.
The calorie deficit diet has always been used for weight loss. You might think any diet causing a calorie deficit works, but that’s not true. Not all weight loss diets actually create a calorie deficit. There are many opinions and experiences about this diet. We’ll go through each of them in detail in this article.
First, to understand exactly how this diet works, we need to know:What is the energy our body gets from food used for?
-
Basic metabolic functions:
Part of the energy is used for the body’s basic vital functions. You can think of the human body like a machine that needs energy for each part to work. Basic functions needed to stay alive include breathing, sending signals, and more.
The amount of energy used by basic functions is called the basal metabolic rate BMR. It's the energy the body uses when resting and the digestive system is inactive for 12 hours. The faster your BMR, the more calories you burn and losing weight gets easier. BMR speed is linked to muscle mass. So athletes have higher BMR than regular people.
-
Food digestion:
The body uses 10-15% of calories taken to burn food and make energy. This depends on food type and is called the thermic effect of food TEF.
-
Physical activity:
Burning calories through activity is obvious. Every movement uses energy. These range from simple stuff like sitting and standing, to moderate like walking, to intense like sports. All need energy but each uses differnt amounts.
What are calories?
Calories are a unit of energy measurement. It's the amount of energy needed to raise 1 gram of water by one Celsius degree. Food gives us energy that our bodies burn to create heat and keep running even when resting.
The amount of calories we use daily splits into the three areas we mentioned before: basic metabolic functions, digesting food, and moving around. Lots of websites can calculate how much energy you should use daily. You can also join us at Fitness Garage to find out..
How do you create a calorie deficit?
Many people eat more calories every day than they need to keep their weight steady. Over time, this extra food turns into fat stored in the body.
You can create a calorie deficit by eating less energy (food) and so taking in fewer calories than your body needs to do its jobs. You can also raise calorie burning like working out. You can do both together.
When there is a calorie deficit, the body uses fat stores for energy to work. Burning fat this way causes weight loss.
How do you do a calorie deficit diet in a healthy way?
1- Cut down the amount of food you eat:
You can do this by eating less meals and avoiding snacks. If you lower your daily food intake enough to create a calorie deficit, you'll lose weight.
2- Increase your physical activity:
You can create a calorie deficit by increasing physical activity like walking and exercising enough to burn calories while keeping the same amount of food.
3- Combine increasing activity with eating less:
You can mix both ways to create a calorie deficit. Divide the calories you want to cut between food and activity for better weight loss results and body shape improvement.
Is the calorie deficit approach effective?
A big plus of this method is you can eat what you want without sticking to specific foods. This way, you can keep eating unhealthy food but still lose weight. So many think a balanced diet is better than just relying on a calorie deficit. You can also combine both methods if you want.
What are the harms of a calorie deficit diet?
Most harms from this diet come from lacking essential nutrients needed for good health. These harms include:
- Constant tiredness and fatigue.
- Paleness of the face.
- Weakened immune system.
- Brittle nails.
- Weak hair.
A severe calorie deficit causes more toxins in the blood which throws off your energy. Also, a severe calorie deficit with low protein intake breaks down muscles to get the protein the body needs. Losing muscle mass slows down metabolism (breaking down and building up processes).
How to lose weight without cutting calories?
1- Eat whatever you want but make it healthy:
Now you know where the energy you get from food is used. so only eat what you need without overeating. The food you eat daily must be a complete nutrition source, with proteins, carbs, fats (healthy fats only), plus vitamins, minerals, fiber, and other nutrients. When you eat complete nutrition, your metabolism speeds up and weight loss becomes faster. It also makes it easier to maintain weight without messing with metabolism.
2- There are rules for eating:
There are two key steps when it comes to eating and losing weight, which are:
-
Chew your food well:
You should chew your food 30-40 times before swallowing. This method improves digestion and makes your brain send fullness signals even with less food. So you feel full faster and avoid eating too much, which helps with weight loss.
-
Avoid distractions:
In the past, our grandparents used to eat quietly, enjoying their food in peace. Now we eat in front of the TV, holding our phones. This distraction makes us unaware of how much we eat, which can lead to weight gain.
3- This is the time to change:
Instead of cutting down food amounts, you can focus on improving food quality. Swap processed carbs for proteins. Replace unhealthy snacks with fruits and veggies.
Rely on foods that take longer to digest to keep you full longer and help build muscles, like proteins and fibers.
4- Water is your secret weapon:
Who hides the benefits of water? It’s the source of our existence. It also helps with weight loss. Water naturally suppresses appetite, speeds metabolism, helps flush out toxins, and drinking enough (8 cups a day) prevents water retention.
5- Sleep healthily:
Try to sleep well, away from stress and worry. Get 6-8 hours of sleep daily. healthy sleep has great health benefits and also speeds up metabolism.
6- Move:
The extra calories left after digestion and basic functions are used in physical activity. so you need to do any kind of movement to burn these extra calories instead of blocking them. Exercise also has other benefits like improving life quality, body shape, mental health, and overall physical health.
