When you exercise or actually when you just move, you spend your energies. Energy is needed for the body to move and stay alive and grow to keep the body warm.
Energy comes from all the foods and drinks you eat. Things like carbohydrates, proteins and fats are mainly the macro-nutrients.
How much energy depends on many things like your gender, body composition, and your activity levels. Energy expenditure is often referred as the sum of the basal metabolic rate (BMR) which is the amount of energy used while being 100% rested, you also need energy to digest and absorb food and that is called the thermic effect. Lastly the energy you spend in sports physical activity.
Sticking to the same body weight will require that the energy intake and expenditure are roughly the same. If you eat a
They are both used to estimate how much calories you burn in a resting state but RMR has more factors than BMR. BMR measures your basal energy expenditure (BEE) which is an estimation on how much calories you burn by doing the basic things your body needs to survive such as breathing circulating blood, repairing cells and growing. Resting energy expenditure (REE) shows you the amount of calories you burn in 24 hours doing the basic body functions, but it also has the calories burned while eating and the small activities that you do daily.
Meaning RMR is slightly higher than BMR, but by only a very significant amount. According to the National Research Council is less than 10% difference but BMR is more accurate as its procedures are more strict.
Children have a higher BMR then adults as they are growing at such a rapid rate, as well as men have higher BMR than women because they contain more muscles needing more energy. The elderly will have lower BMR because their muscle mass decreases with age. The average adult needs about 1.1kcal each minute to keep all the basic body functions
This is called a plateau and further weight loss can be hard to achieve without some help.

Glycemic index is the measure of how quickly blood glucose rise after eating a particular kind of food. This is used by estimating the how much each gram of carbohydrate consumed raises a person’s glucose level. During intense exercise, the body uses glucose as energy source before it starts relying of fats. “Prolonged exercise can only be continued when there is an adequate amount of carbohydrate available to fuel muscle and the brain”(William,2004). This shows that the amount of carbohydrate/glucose that is found within the body’s tissue has a significant amount of influence to play on how effective the early hours of an exercise would be. Glycemic index helps one to know how effective the carbohydrate/glucose within the body is functioning during exercise.

When something gives us energy, it means more than to just give us the required power to work or move along for such a specific task. In biological terms, it means to have your energy be transported through your body and placed by cells into biomolecules. Biomolecules such as lipids and carbohydrates. It then stores that energy in our body.
Our metabolism, “the totality of an organism’s chemical reactions”, manages energy usage and production of cells. We use energy constantly and our metabolism breaks down food through complex chemical reactions into energy our cells
AIM: - the aim of this experiment is to find out what the effects of exercise are on the heart rate. And to record these results in various formats. VARIABLES: - * Type of exercise * Duration of exercise * Intensity of exercise * Stage of respiration
My resting heart rate is 64 bpm and my bleep test score (which I aim
When a person exercises the body uses either sugar or fatty acids as fuel to create energy. During the beginning of an exercise most of the sugar that is used as fuel comes from the bloodstream or the muscles. After about 15 minutes the fuel starts to come from the liver. When one exercises after 30 minutes the body receives energy from free fatty acids and glycogen gets stored resulting in a decrease in blood sugar levels. Glycogen is the sugar stored in the liver and muscles.
It was once commonly believed that all calories were essentially the same, and that controlling your weight was simply a matter of keeping the total number of calories in the right range. Many people still do believe this, even though it is clearly false.

There are twenty four hours in one day yet often times we feel like we don't have enough time to get everything done. As humans we come up with excuses on why we can't do things. A lot of feel like we just don't have enough time to go workout, but did you know research shows you’re more likely to get more done after working out, than if you don't work out at all. People that take time for exercise on a regular basis are more productive and have more energy throughout the day. We often take time out of our day and invest our time and money into some sort of "energy boosting" product when we have the cheaper and more effective solution the outdoors....
Exercise, or physical activity helps your body in many ways. For example, exercise helps control the weight of a human. It helps prevent people gaining unwanted weight and helps people who have unwanted weight to lose it. (mayoclinic.com) When we eat, we are taking in calories, and then when we exercise we burn off those calories taken in before. This helps us control the amount of calories by burning them off, otherwise our body would have stored them away as fat. (fitday.com)
