Over the years research has taken place to measure the number of calories burned by people who have a healthy weight, and also those that are overweight, when they are resting. The measurement taken in this instance is the oxygen that they breath in, and the carbon dioxide that is subsequently breathed out. This is to ascertain how much energy these people expend through just their bodies working normally, without any added movement. Many results have shown that those people who are overweight, use up more energy for this. The primary reason is that their bodies are larger, they have bigger muscles and organs that make up their composition.
However, once a difference in the size of people's bodies have been taken into consideration, there have been similarities shown in the metabolic rates of those with a lean, or thinner figure, and people who are deemed to be obese.
Somebody's basal metabolic rate can be affected by the size of their body, and how the size is constituted. Fat requires less energy to function than muscle. The trend with everybody is that as we age we will lose muscle from our body, but gain fat. This factor upholds the fact that our basal metabolic rate gradually decreases as we get older.
So two people who are of the same age and weight can have different metabolic rates if one is more muscular than the other.
Naturally we also use up energy each day as we move around while carrying out our daily activities. Basal metabolic rate and the energy needed for physical activity make up the total energy that we expend. Your total energy needs depend primarily on how active you are.
But you hardly eat anything right?
It is common for overweight people to believe that they eat very little, yet still put on weight. This is why many overweight people blame their weight on a 'slow metabolism'. However, research has shown people tend to eat more than they think they do.When people are asked to write down everything that they ate and drank in a day, often they will miss things out. The reason for this can be to give a different impression to those conducting the research, or because they honestly forgot some things. There is also the chance that after knowing that what they were eating was coming under scrutiny, they could have gone for healthier options.
The point is that if you consume more calories than you body requires, you will gain weight.
If you genuinely want to be able to lose weight then understanding your metabolic rate is critical, as this will lead to you knowing how many calories you need to be eating each day. Once that is clear and you are able to amend your diet and eating habits to suit this number, you are going to be going the right way to be able to lose weight and slim down.
This is the most simple and effective way to help your metabolism and achieve your weight loss goals. It beats fad diets and miracle pills that are sold to thousands of people looking for a quick fix, and subsequently failing.
