Role Of Metabolism In Our Body
METABOLISM
"Metabolism is the process by which your body converts what you eat and drink into energy. During this complex biochemical process, calories in food and beverages are combined with oxygen to release the energy your body needs to function."

FAST METABOLISM
If you're blessed with a fast metabolism, your friends may tell you how jealous they are that you can eat whatever you want and not gain weight. Genetics may be the major player in your fast metabolism. If you're a muscular man, you may have an innate higher metabolism, but your higher calorie burning may also be due to hard work. Working out and building muscle pay off when it comes to your metabolic rate, which is why athletes and body builders get to eat large quantities of food.your metabolism rate is how quick you break up food. Say if you just had a very big dinner and in two hours your hungry again, means your metabolism rate is very high (Not a bad thing.)
If you want to lose weight so try to increase metabolism in your body.
Body size, age, gender and genes all play a role in determining your metabolic rate.
Muscle cells require more energy to maintain than fat cells, so people with a higher muscle to fat ratio tend to have a higher BMR.
As we get older, we tend to gain fat and lose muscle. This explains why the BMR tends to decrease with age.
In general, men tend to have a faster metabolism as they have more muscle mass, heavier bones and less body fat than women, which is why their daily calorie allowance is higher.
Your metabolism may be partly determined by your genes, although this is not yet fully understood. Genes definitely play a role in muscle size and your ability to grow muscles, both of which affect your metabolism.

If you're cutting calories to lose weight, don't go too low. Dipping below 1,200 calories for women and 1,800 calories for men may cause your metabolism to stall, essentially creating a slow metabolism. Bring the calories back up to increase your calorie-burning power.
Adding muscle to your frame might give your slow metabolism a boost. Strength-train twice a week using free weights or body-resistance exercises such as squats, lunches and push-ups, to build calorie-burning muscle.
Getting more cardio is another way to jump-start your metabolic rate. Also, find more ways to be active. Up your daily walk from 30 to 60 minutes. Take a walk around the office every hour. Pace when you're on the phone. Stand at a counter to type your emails and letters.

SLOW METABOLISM
A slow metabolism may mean having to ease up on portion sizes. ... The higher your metabolic rate, the more calories you burn performing these chemical processes. A fast metabolism can help with weight loss, as it means you can eat more calories while still burning fat and dropping weight.With some diets, your body is forced to break down muscle to use for energy. The lower your muscle mass, the slower your metabolism. With less muscle and aslower metabolism, it then becomes a lot easier to put body fat back on after coming off the diet.
If you're putting on weight while eating the same kinds of food you've eaten for decades, your metabolism may be slowing down. Muscle burns more calories than fat tissue, but as you get older, you may be less active and your calorie-burning muscle turns into fat, leading to the metabolic slowdown. This is also one reason why women generally have slower metabolisms than man -- genetically they have less muscle. Eating too few calories can also cause a drop in your metabolic rate, as much as 30 percent, according to the University of Illinois McKinley Health Center.
If you're having a difficult time gaining weight or can't stop losing due to your fast metabolism, you need to eat more calories. These extra calories should come from nutritious foods to promote overall good health and weight gain. For extra calories, eat whole-grain bagels and dense whole-grain bread; cheese and whole milk; eggs, fatty fish and beans; avocados and 100-percent fruit juice; peas and potatoes and nuts, seeds and oils.
Add high-calorie snacks such as 1/4 cup of dry-roasted mixed nuts for 200 calories or 1/4 cup of hummus with a 6-inch whole-wheat pita for 260 calories. A high-calorie nutrient-rich smoothie such as a 6-ounce container of yogurt blended with a medium banana, 1 cup of sliced strawberries and 2 tablespoons of almond butter for 480 calories can up your calorie intake.
