Calibrate Weight Loss | How To Lose Weight Without Exercising | The Science Behind

The first thing you must understand about exercise is that just because you are burning calories does not mean you are burning fat; you can’t lose body fat just from burning calories.

To lose weight and get in shape, you must have a good diet and exercise regularly to burn fat. Your primary focus when you exercise should be losing body fat.

The Science Behind Losing Body Fat

When we exercise, our bodies will start burning calories, but the calories that are burned are the calories from carbohydrates in our body.  Please understand that if you continue to only burn calories from carbohydrates, you will lose mostly “water weight” which leads to a decrease in your metabolism.

To burn calories from your stored fat; your body requires adequate oxygen. There is a certain amount of oxygen that your body needs to start burning fat. 

The only way for you to measure the amount of oxygen needed for your own body is to keep up with your target heart rate during exercise.

The calories burned from carbohydrates are your energy calories. If you lose too many energy calories then your muscles will not receive enough energy to increase your metabolism which indirectly burns fat. Therefore you must increase your calorie intake when you are on an exercise program to replace your burned energy calories.

How To Burn Fat During Exercise

During aerobic(oxygen involving) exercise, your body goes through several stages before it reaches the point where you are burning fat. You will hear people say that you are only burning sugar (carbohydrates) not fat during the first 10 minutes of exercise. This is true to a certain extent.

When you exercise you must move at a steady pace (not too fast, not too slow) so your body will utilize your stored fat (not carbohydrates or sugar) as its energy source. I say this because you will continue to burn sugar past the 10-minute mark if you are not working out hard enough for your body to want more oxygen, or you are working out too hard and you can’t supply your body with enough oxygen for fat burning.

Also, remember that just because you reached the fat burning stage does not mean you will stay there. Staying at the fat-burning stage once again depends on if you are moving at a pace that is right for your body. Make sure that you are within your target heart rate range.

How To Burn Fat During Rest

The only way for you to continue to burn fat calories hours after you have finished working out is through weight training(anaerobic exercise). Weight training is an anaerobic activity that will cause you to burn more calories than aerobic exercise.

The calories that you are burning during weight training exercises are mostly calories from carbohydrates (meaning you must eat even more calories per day for energy), but the calories you burn at rest are mostly calories from fat.

weight training increases your metabolism which uses your stored fat as energy.

Summary

For your body to lose fat effectively, you must do aerobic (cardio) and anaerobic (weight training) exercises.
