Weight loss: The no-diet approach
Whether you are trying to lose five pounds or more than 50, the same principles determine how much weight you lose and how fast your weight loss will occur. Remembering the following simple healthy eating guidelines and putting them into practice can lead to weight reduction without the aid of any special diet plans, weight loss programs, fitness books, or medications.
Our body weight is determined by the amount of energy that we take in as food and the amount of energy we expend in the activities of our day. Energy is measured in calories. Metabolism is the sum of all chemical processes within the body that sustain life. Your basal metabolic rate is the number of calories (amount of energy) you need for your body to carry out necessary functions. If your weight remains constant, this is likely a sign that you are taking in the same amount of calories that you burn daily. If youre slowly gaining weight over time, it is likely that your caloric intake is greater than the number of calories you burn through your daily activities.
Every adult is in control of the amount of food he or she consumes each day, so our intake of calories is something we can control. To a major degree, we can also control our output of energy, or the number of calories we burn each day. For some people, due to genetic (inherited) factors or other health conditions, the resting metabolic rate (RMR) can be slightly higher or lower than average. Our weight also plays a role in determining how many calories we burn at rest -- the more calories are required to maintain your body in its present state, the greater your body weight. A 100-pound person requires less energy (food) to maintain body weight than a person who weighs 200 pounds.
Lifestyle and work habits partially determine how many calories we need to eat each day. Someone whose job involves heavy physical labor will naturally burn more calories in a day than someone who sits at a desk most of the day (a sedentary job). For people who do not have jobs that require intense physical activity, exercise or increased physical activity can increase the number of calories burned.
As a rough estimate, an average woman 31-50 years of age who leads a sedentary lifestyle needs about 1,800 calories per day to maintain a normal weight. A man of the same age requires about 2,200 calories. Participating in a moderate level of physical activity (exercising three to five days per week) requires about 200 additional calories per day. It is important to look for a plan that includes strategies for maintaining weight loss. There is nothing worse than regaining the weight that took you an enormous amount of hard work and patience to lose.
Most popular diets are considered fad diets. There is no clear definition for what constitutes a fad diet. Merriam-Webster defines a fad as a practice or interest followed for a time with exaggerated zeal. Fad diets often promise quick results with a short time commitment. Long-term success requires permanent changes in behavior, diet, and activity. The best approach for weight loss is reducing the number of calories you eat while increasing the number of calories you burn through physical activity. To lose 1 pound, you need an expenditure of approximately 3,500 calories. You can achieve this either by cutting back on your food consumption, by increasing physical activity, or ideally, by doing both.
For example, if you consume 500 extra calories per day for one week without changing your activity level, you will gain 1 pound in weight (seven days multiplied by 500 calories equals 3,500 calories, or the number of calories resulting in a 1-pound weight gain). Likewise, if you eat 500 fewer calories each day for a week or burn 500 calories per day through exercise for one week, you will lose 1 pound.
