What is suitable exercise to Gain weight?

Resistance training exercise is suitable and desired exercise for a weight gain program

You do not want to gain weight just in body fat. You need to add muscle mass. Resistance training exercise such as lifting weights help you increase the muscle size.

Do NOT engage in aerobic exercises (Running Stationary Bicycling). Aerobic exercise help you lose body fat (weight loss). With aerobic exercise, you may lose more weight than gain weight.

Underweight is a problem too

If being too fat is a health risk, you might think being too thin is good for you. But contrary to that old adage, "you can never be too rich or too thin," being overly skinny carries its own health risks.

Underweight is defined as having a body mass index (BMI) below 18.5. For example, someone who is 5'5" and weighs 110 pounds would have a BMI of 18.3, which is considered underweight.

While complaints of being "too skinny" may spark envy from those who tip the scales in the other direction, weighing too little can increase your risk of osteoporosis and fertility problems, weaken your immune system, and cause other health problems.

As well, if you aren't happy with your body - because you want more curves or muscle - being too skinny can make you feel self-conscious and reduce your self-esteem.

There are a number of reasons why someone may be underweight. Some people are just naturally thinner than others, because they tend to burn more calories or eat less. Other people may lose weight as a result of certain medications or an underlying medical condition. Sudden weight loss without trying can also be an indication of a health problem, so talk to your doctor.

For some people, being too thin is a self-induced condition, known as anorexia nervosa. Anorexia is a condition where sufferers may diet to the point of near-starvation or exercise excessively all in the name of weight control. Though anorexia is a psychological illness, it can have serious physical complications, including heart and lung problems, osteoporosis, and, in some cases, death.

Many people with anorexia do not see their weight as a problem and may go to lengths to hide their habits. If you believe someone you know is suffering from anorexia, encourage them to seek help for their condition.

Reasons for Being Lean / Underweight

While many people view being underweight as a sign of good health, in reality, it could be the sign of an underlying health condition. Being underweight can lead to infertility, osteoporosis and a weakened immune system, as well as having negative psychological effects such as a poor self-image. There are several reasons why a person can be underweight.

Naturally Thin

1. For some people, being underweight, defined as having a body mass index (BMI) of 18.5 or less, is a result of a high metabolism rate or habitually consuming less food than heavier people. Working at a job that requires constant walking or motion such as a police foot patrolman or warehouse worker causes a rapid burning of calories that also serves to keep weight off.
2. Eating Disorders
3. Eating disorders such as bulimia or anorexia can also result in a person being underweight. While the root cause of these conditions is psychological, the physical effects can be devastating since the body is often deprived of necessary nutrients for survival. It can also lead to cardiovascular, pulmonary and weakened bone conditions and, in some situations, even death.
4. Genetic Theories
5. There is a school of thought that being underweight is caused by a person's genetic makeup. Some genetic research has posited the theory that there are lean cells and fat cells, which could be why thinness and obesity can sometimes run in families. The theories indicate that a person' genetic disposition has a greater influence on weight than calorie consumption.
6. Health Conditions
7. Being underweight can result from health conditions such as a sudden illness. The body will use any excess calories to ward off disease, which results in a loss of weight. Thyroid conditions can also result in the inability to keep on or gain weight. If sudden weight loss occurs, a visit to the family doctor is advisable.
8. Gaining Weight
9. The most efficient way for an underweight person to gain weight is to increase the number of calories consumed per day. This can be achieved by first keeping a food diary for a week to determine what foods and how many calories are consumed, then swapping out the lower calorie items for higher ones. Rather than consuming mass quantities of food in two or three meals per day, it is better to eat several smaller meals throughout the day to avoid feeling bloated.
