Weight loss is a matter of balancing the intake of calories and expenditure of energy, according to the Mayo Clinic. The goal to successful weight loss is to burn off more calories than you consume. Although there are drugs and surgical procedures for weight loss, to keep off the weight, you need to make a long-term commitment to a healthy lifestyle that involves both diet and exercise. If you are overweight, losing extra pounds will make you feel better and look better. You’ll also decrease your chances of weight-related diseases such as hypertension, diabetes, osteoarthritis, heart disease and some types of cancers, according to Medical News Today. Before you begin any new program, consult your physician.
Diet
To lose 1 pound of fat, the National Institutes of Health states that you should consume about 3,500 fewer calories. Some of the ways you can do this include decreasing your portion sizes, avoiding high-calorie foods and limiting the amount of high-calorie drinks you consume. Most successful diet plans are low in fat and sugar but contain the essential nutrients to maintain a healthy body.
Exercise
To lose weight by exercising, you need to calculate the number of calories each activity burns for the amount of time you are involved. According to the National Institutes of Health, to lose a pound of fat, an average-sized adult would need to walk more than 30 miles. If you can walk two miles per day, you should be able to lose 1 pound in 15 days. The ideal exercise program for most people is a combination of cardiovascular training, strengthening and stretching.
Drugs
Although the best way to lose weight is with a combination of diet and exercise, the Mayo Clinic states that there are some people who can benefit from weight-loss drugs. Drugs are typically prescribed for people who are severely overweight and have an immediate risk of developing weight-related diseases. Keep in mind that once you achieve your weight-loss goal and get off the drugs, you will likely regain all the weight you lost unless you adopt a healthy lifestyle.
Surgery
You may be a candidate for weight-loss surgery that involves shrinking the size of your stomach if you are a man with 100 or more pounds to lose or a woman who needs to lose 80 pounds. This option is typically offered after other methods to lose weight have failed. After the surgery, you will be limited by the amount of food you can consume and digest. The typical person who undergoes this surgery loses weight quickly, and those who follow the doctor’s orders will be able to keep most of it off. Some of the complications may include blood clots, infection and hernias.
Unwanted Weight Loss
Some people experience unwanted weight loss. This can be the result of cancer, diabetes, heart failure, celiac disease, Crohn’s disease, HIV/AIDS or a number of other diseases. If you find yourself losing weight without wanting to, see your doctor immediately for diagnosis and treatment. It can make the difference between life and death or debilitation.
