Being underweight can pose many health problems. But before we leap in to tackle the problem one should know what is exactly meant by being underweight. This is decided if the Body Mass Index(BMI) is less than 18.5. According to WHO(World Health Organization) the BMI is calculated by weight in kilograms divided by the square of the height in meters (kg/m2). For example, an adult who weighs 70kg and whose height is 1.75m will have a BMI of 22.9.
BMI = 70 kg / (1.75 m)2 = 70 / 3,0625 = 22.9
WHO's BMI Scale
18.4 and below = Underweight
Between 18.5 and 24.9 = Normal
25 and above = Obese.
But one should not assume that these values are correct. They are just approximate inexpensive methods to quickly check if a person is underweight or overweight. Even though the factors that decide the body mass is mainly adipose tissue where the fat is stored, the muscle mass and water percentage in the body and bone density also contribute to BMI as much. So if the person has high percent of any of the above factors other than adipose tissue doesn’t mean that he is obese. So an alternate to BMI, Body Volume Index (BVI) was devised in the year 2000. It is a computer based measurement which calculates the location of the fat in the body.
Once we know that a person is underweight we need to chalk out the common reasons which can be -Malnutrition, Stress/depression/anxiety, Anorexia nervosa/bulimia nervosa, Tuberculosis, HIV/AIDS, Hyperthyroidism, Ulcers, Malfunction of digestive organs, Drug use.(treatment,overdose,stimulants), Type1 diabetes, Cancer, Genetically underweight. Puberty (height increases, body cannot catch up with muscle/fat growth), High Metabolic rate, Low appetite, excessive cigarette smoking etc. Being genetically underweight is considered normal provided a physician's assessment rules out any other anomalies. Because the fat cells in the body are genetically determined no matter what you do you cannot get rid of them or increase them. For example - fat people who follow a diet chart for a month may successfully lose weight but not their fat cells, cause in this case the fat cells are not gone they only got shrunk. But once the calories come back they grow back too.
The risks that you can be exposed to being underweight can be
· Pregnancy complications- a woman must have certain amount of body fat to sustain a healthy and growing baby throughout pregnancy. Low fat levels in the body can lead to still births,pre-term labor, if not least the restricted growth of the baby.
· Infertility in women- where dysfunctional ovulation impedes pregnancy,
· Osteoporosis- meaning porous bones. This is a particular insidious consequence, (when bones become fragile and break easily) because the affected persons do not notice the danger. After the occurrence of first spontaneous fractures the damage is often already irreversible.
· Amenorrhea- absence of menstruation
· Anemia-lack of adequate blood.
· Low blood pressure
· and unconsciousness.
After we are thru with the pros and cons of underweight, we can proceed to set the weight gaining goals. It is helpful to understand that to gain weight one must consume more calories than one burns. Online calorie calculators can help determine how many calories an individual is burning during certain activities and how many average calories are contained in a food item. However simply taking high calorie foods that lack nutritional value will not solve the problem. These foods cannot provide the fuel that body needs and instead you can end-up having unhealthy increase of body fat. The point is to increase quality calories as well as quantity.
Dietary supplements provide a larger number of calories in a smaller volume. Intake of starchy grains and vegetables, including rice, oats, whole meal pasta, potatoes, corn, carrots, pumpkin, natural fruit juices, skim milk and fruit smoothies are helpful. Vitamin D that our body can produce by itself when exposed to the Sun helps to process calcium to increase bone density (helps in cases of osteoporosis.) Healthy fats, so-called, are found in nuts, apricots, raisins, prunes, dates, dried figs, avocadoes, fish and olives which also provide additional healthful nutrients. Fats from animal products (fatty meats, butter and cheese) and tropical oils (coconut cream and palm oil), common in fast foods, on the other hand, could lead to a raised LDL cholesterol levels that are unhealthy fat and calories.
And increase in muscle mass is as much healthy through regular resistance training( also known as strength training or weight training). This type of exercise is completely opposite to fitness training like running, walking or swimming. These exercises use your muscle to lift, push or pull against a resistance. The resistance could be anything from sand bags, pin loaded weight, hydraulic resistance apparatus or just water. Performing this training regularly stimulates optimum muscle growth also the bone density. Small amounts of aerobic activities (such as walking or running) are important for your cardiovascular health, but any more than 20-30 minutes three times a week will be counterproductive to weight gain. Extra activities will burn off the extra calories you are eating, preventing weight gain. Recording your calorie intake and exercise regimen will keep your inspiration up and most importantly to keep your weight in check.
