Gaining Weight the Healthy Way

According to the National Heart, Lung, and Blood Institute criteria, a body mass index (BMI) of less than 18.5 is considered underweight. See the BMI Calculator on the McKinley web site to determine your BMI. Significant underweight is associated with negative health effects including loss of menstrual function, complications with pregnancy, complications with surgery, and slow recovery after illness.

Some individuals want to gain weight or muscle mass even if they are not underweight. Athletes may want to increase muscle mass to help them perform their sport better. No matter what the reason for wanting to gain weight, taking steps to gain weight healthfully is recommended.

A sound weight gain program combines exercise to boost muscle development along with a balanced diet to provide nutrients for energy and muscle growth. The addition of 250-500 extra calories per day will cause a weight gain of approximately 0.5-1 pound per week. This number may vary because of activity level and genetic makeup.

What is a balanced diet?

Consuming more calories than you expend will cause weight gain, no matter what type of food you eat. However, you will be more nutritionally sound if you get most of those calories from the following groups:  grains, fruits, vegetables, dairy or non-dairy substitutes, meat and/or plant proteins.

What’s the best way to increase calories?

Expensive, specialized weight gain formulas are usually unnecessary for most healthy persons. Extra calories can easily be consumed through food. To avoid feeling stuffed, make small additions of food to your normal diet. Those extra calories will add up! Here are some ideas to get you started.

The following foods can help you boost your calorie intake:

Strength Training for Weight Gain

Strength training is the best way to add lean muscle tissue to your frame. A balanced program should include exercises for all the major muscle groups: chest, back, abdominals, biceps, triceps, shoulders, quadriceps and hamstrings. Example exercises include: bench press, seated rows, crunches, bicep curls, overhead tricep extensions, leg press and leg curls.

Your program should include at least one exercise for each of these muscle groups. Depending on what your goals are, you can increase the number of exercises for a particular muscle group to 2-3.

You should work up to doing 2-3 sets of 4-8 repetitions of each exercise in your program. Once you can easily complete 8 repetitions in each set, increase the amount of weight you lift.

Don’t cut out cardiovascular exercise altogether when trying to gain weight. Try to get 2-3 workouts in each week, but you can keep them short, 20-30 minutes, and of a moderate intensity.

Note: Gaining weight is easier for people with certain body types. Realize you may be limited to some extent by your genes. You may not be able to look like a body builder, but eating extra calories and working out will help you grow stronger and become more fit. Appreciate the body you have and care for yourself as well as you can.
