Losing 20 kg of body weight is a significant challenge. It can take anywhere from several months to multiple years to achieve this goal, depending on a variety of factors. However, if you're eating 900 calories per day and spending an hour on a stationary bike each day, you may be able to reach your goal relatively quickly. Here's what you need to know about the process.
The Calories-in, Calories-out Model
The first step to losing weight is understanding the calories-in, calories-out model. This model states that for every 3,500 calories you burn, you will lose one pound of fat. This means that if you want to lose 20 kg, you need to burn 70,000 calories. It's important to note that while this model is simple, it doesn't take into account factors such as genetics, muscle mass, and body composition.
How Many Calories Do You Need to Burn?
In order to lose 20 kg in a reasonable amount of time, you need to burn between 500 and 1,000 calories per day. If you are eating 900 calories per day, you'll need to burn an additional 400-500 calories to reach your goal.
How Much Exercise Do You Need To Do?
The amount of exercise you need to do depends on several factors, such as your current weight and body composition. However, if you are eating 900 calories per day and want to lose 20 kg, you'll need to do at least an hour of moderate-intensity exercise most days of the week. This can include activities like walking, running, swimming, or cycling.
Will You Need To Make Changes To Your Diet?
In addition to exercising, you'll need to make changes to your diet if you want to lose weight. Eating 900 calories per day can help you lose weight, but it's important to make sure that the calories you're consuming are nutritious and provide your body with the energy and nutrients it needs. You should also avoid eating processed, high-calorie foods, as these can slow your progress and make it more difficult to reach your goal.
What Other Factors Can Influence Weight Loss?
In addition to diet and exercise, there are a few other factors that can influence your weight loss. Getting enough sleep is essential for maintaining a healthy metabolism and keeping your energy levels up, while stress can lead to increased levels of cortisol, which can prevent weight loss. You should also be aware that genetics and body composition can play a role in how quickly or slowly you lose weight.
How Long Will it Take Me To Lose 20 kg?
It's impossible to say exactly how long it will take you to lose 20 kg, as everyone's body is different. However, if you are eating 900 calories per day and exercising for at least an hour each day, you may be able to reach your goal within a few months.
