Battling Obesity

The BMI (Body Mass Index) has become a useful tool in managing weight and body fat percentage in the last 20 years. Calculating it requires only simple arithmetic and can be performed by anyone. It’s important because it provides an objective measurement that, combined with the appropriate scale for age and body type, helps someone manage their body weight more scientifically.

Judgments about body weight can easily become clouded by emotionalism. It’s good to be passionate about managing your body, but you need to get a good grounding in facts, first. BMI is an important tool for achieving that goal.

Nutrition and health science is constantly evolving, and it often seems as if the latest study contradicts earlier ones. It’s hard to know what to believe. But, over the last few decades, a wide array of independent studies has tended to confirm some conclusions about the relationship between excess body fat and associated health risks.

The basic conclusion is that anyone who is considerably overweight is at higher risk for a number of potential health problems. These include various forms of heart condition, high blood pressure, diabetes, colon cancer, liver damage, gallstones and others.

Women are the major consumers for weight loss programs and diets. Men tend to focus more on exercise. But either topic is, and should be, popular with both sexes. Men, too, need to concern themselves with proper diet and nutrition as part of a rounded program of weight loss and health.

Particularly with the onset of middle age, diet becomes a greater concern for men. Calorie needs are typically highest in the mid-20s and taper off about 2-4% with every passing decade. For an average-sized male (say, 5 ft 9 inches and 170 lbs), the average number of appropriate calories per day, 2500, reduces to 2200-2350.

Nearly everyone today worries about being overweight. We’re constantly inundated with messages from TV and the Internet about widespread obesity and the risks of being obese. Whether it’s health issues or social acceptance, no one wants to be fat.

But if you look at it from an evolutionary aspect, the ability to store excess calories in the form of fat cells is a very life-serving ability. When a person consumes more calories than the body uses for muscle movement, internal temperature maintenance and cellular repair the remainder is stored in the chemical bonds of fat cells. Technically, it’s stored in something called ‘adipose tissue’.

If you are trying to lose weight or just maintain a healthy weight, you should understand the connection between the energy your body takes in and the energy your body uses. Energy is taken in through food you eat and beverages you drink. Energy is used by activities performed. To lose weight you have to use more calories than you take in. To maintain, you have to match the calories you take in with those that you use. Eating a healthy diet and being physically active can help you reach either goal.

The number of calories you need each day depends on your age, activity level and whether you are trying to lose, gain or maintain your weight. Your diet should include the most nutritious foods including fruits, vegetables, whole grains and fat free or low fat milk and dairy products. Foods should be rich in vitamins, minerals, fiber and other nutrients.
