The relationship between basal metabolism and weight is complicated, however, Pontzer says. But each individual cell is not more active or burning more calories per minute just because there are more cells, Pontzer says. How much energy each of these cells uses depends on its role in the body.
Cells forming muscle, nerves or liver tissue use more energy than those forming fat. Although some factors can cause temporary changes in energy use, cells generally hum along at a rate that is sufficient for their role. One way to nudge the metabolism needle is to change the amount of some cell types by building more lean mass or muscle.
More muscle means more metabolically demanding muscle cells, which translates into a higher resting metabolism. Individual differences in this mass underlie most of the variation in metabolism from person to person, according to Urlacher.
Two people with the same body weight but different proportions of lean mass to fat can eat the same number of calories and still have different weight-gain outcomes. In terms of weight loss, the timing of a gym visit also might make a tiny difference, Urlacher says.
A resting heart rate of 50 beats per minute for one person versus 70 for another just means the heart with the slower resting rate might be more efficient at getting oxygen to tissues, Pontzer says. Bumping up an exercise regimen to burn through more calories may also seem like a sure way to boost metabolism and lose weight.
A high metabolism means you'll need to take in more calories to maintain your weight. That's one reason why some people can eat more than others without gaining weight.
A person with a "low" or slow metabolism will burn fewer calories at rest and during activity and therefore has to eat less to avoid becoming overweight. Lean people tend to be more active during everyday activities than people who are overweight. They may "fidget" more — that is, they tend to be in motion even when engaged in non-exercise activities.
Whether this tendency to move more or less is genetically programmed or learned remains uncertain. But it can add or subtract hundreds of calories each day. Obese people expend more calories, on average, than lean people during most activities, in part because it takes more effort to move around.
But they tend to be more sedentary, which makes it harder to get rid of body fat. It's part truth and part myth that metabolism is the key to weight.
The rising tide of obesity in this country cannot be blamed entirely on an inherited tendency to have a slow metabolism. Genes do not change that quickly. Something environmental — particularly, changes in diet and exercising too little — are much more likely culprits.
Age can be a factor, too, although new evidence suggests metabolism reaches a peak earlier in life and slows down much later than previously thought. The reality is that for most people, excess weight is not all due to bad luck, thyroid trouble or some other unexplained, uncontrollable external factor.
For most of us, calories in, calories out has a strong influence on changes in weight over a lifetime. Regardless of whether your metabolism is fast or slow, our bodies are designed to store excess energy in fat cells.
So, if you eat and drink more calories energy "intake" than your body expends energy "output" you will gain weight. So if your goal is to lose weight, you need to eat fewer calories, burn more of the calories you eat, or even better, do both.

Top of the page. Overview How is it that two people of the same age, gender, and height can eat the same foods and be equally active, but one gains weight while the other loses it? The age-metabolism-body fat equation As you age, your metabolism naturally slows down.
Metabolism refers Metzbolism all the chemical processes going on continuously inside your body that allow life metabolsm normal Promote a heart-healthy lifestyle maintaining Metaboljsm functioning in metabolis, body Boosted fat metabolism potential called homeostasis. Metabolixm processes include those that break down nutrients from our food, and those that build and repair our body. Building and repairing the body requires energy that ultimately comes from your food. The amount of energy, measured in kilojoules kJthat your body burns at any given time is affected by your metabolism. Achieving or maintaining a healthy weight is a balancing act.

One piece of the puzzle is metabolism. How well your body burns energy to keep up basic functions like heartbeat, breathing, and thinking is called your basal metabolic rate. We often just call it "metabolism. Can you change your metabolism? Whether you're born with a fast, average, or slow metabolism, there are things you can do to speed yours up or slow it down.
