Everyone has that one friend who can eat whatever they want and never go up another pants size. This is due to genetics. Everyone is born with a unique metabolic rate. So, just how some people can eat whatever they want in vast quantities and not have to worry about a growing gut there are others who have to be more careful about the kinds of foods they consume as well as the quantities.

Because of the variance in metabolic rates in individuals it is important to know yours well in order to avoid over-eating. If ones metabolic rate is too low it may be a sign of thyroid issues and a doctor should be consulted in order to increase metabolism.

Portion Size

Since the 1970s the average portion size in restaurants and recipe books has grown. It is also continuing to grow which signals that obesity in adults is only going to become more of a problem. Some studies have shown men are more likely to finish what is put in front of them than women.

Due to this the increase in portion sizes affects men's obesity more. Even a slight increase in portion sizes will have a cumulative effect on weight over months and years.


Lifestyle is another major cause of obesity in adults. Many men become inactive during their mid-twenties when they enter the work force. This causes the amount of calories they burn to go down. This is especially true for those males that work jobs where they are sitting for the majority of the time.

If you continue eating the same amount as you were before becoming less active weight and fat will slowly accumulate. A few pounds gained a year do not seem like much but it adds up and often leads to obesity and further medical complications. Lifestyle choices such as whether or not one participates in sports and outdoor recreational activities effects obesity.


With junk food and fast food being affordable and readily available it is no surprise that this is one of the leading causes of obesity in adults. Fast food is such a big contributing factor because it is packed full of calories and simple carbohydrates.

The high caloric content of these meals makes the food act on the pleasure centers of the brain making the consumer feel a sense of well-being. This is why binge eating of fast foods is a common phenomenon. Men should try to avoid junk foods and find a way to reduce appetite and decrease calories intake.

Obesity Management

Achieving obesity management goals is a very complex task. The most basic goal is to reduce body weight and promote healthy body composition by exercising, eating wholesome foods at a right quantity, and sleeping enough. Weight loss is achievable through many methods including diet and exercise.
Another challenge in obesity management is to reduce body fat. The goal is to lose the fat mass (body fat) that is more than three percent of lean body mass.
The challenge in the weight loss process is to achieve a good level of physical activity by including exercise in the day. To reach the goal, a person will need to learn to identify when and how to increase physical activity, and then to increase it to the highest level possible while avoiding all the potential negative consequences like heart rate and blood pressure.

While obesity is a complicated issue with multiple variables, such as gender, genetics, age and even nutrition, there's still one important variable that is common in all areas of life - calories. So how do you get started?

Calories in Obesity Management

Calories are critical! They determine the type of food you eat, the energy you expend and your body's response to exercise. Your goal is to create a healthy number of calories for you - this will be referred to as your BMR (Basal Metabolic Rate). Your BMR is also measured even when you're healthy: you're not overweight or obese because you eat right.
Your basal metabolic rate will continue to increase over time if you eat appropriately. The goal varies depending on how much fat you have to lose, how lean you are, and to what intensity you are at your workouts.
The most common way to get started on calorie maintenance and weight loss is through an online calorie-tracking platform. You would start by creating a profile and logging your workouts and your activities. You'd then track your calories, and after a month or so, you'd check the results to see how you're doing.

Once a person has achieved this target number of weight loss, he needs to maintain his weight loss.
