How BMI Works and What You Can Do to Get Up to a Healthy Weight
You have a BMI of 15-18, now what? The term Body Mass Index or BMI is very prevalent nowadays as people put more focus on their health and reaching and maintaining a healthy weight. But what is BMI? What is a healthy BMI? How do you calculate it? And what does your BMI mean? This article will explain more about BMI and, specifically, a BMI of 15-18.
What is Body Mass Index (BMI)?
Body Mass Index is a measure of healthy body weight for a given height. Calculating your BMI will tell you what category your body composition falls into. If your BMI is less than 18.5, which we will be talking about here, you are considered underweight. A BMI of 18.5 to 24.9 is in the healthy weight category. 25 to 29.9 is overweight, and a BMI of 30 or higher is considered obese.
How Do I Calculate BMI?
The BMI Formula is simply dividing your weight in kilograms by your height in meters squared. When using pounds and inches, again, divide your weight by height squared but then multiply by 703 to convert the units back to kilograms and meters.
BMI of 15-18: The “Underweight” Category
If your BMI works out to 15-18, you are in the underweight category. This is the designation just below the healthy weight category. For example, a healthy weight for a 6-foot tall man is between 140 and 183 lbs. If that person has a BMI of 15-18, that means they will weigh between 114 – 140 lbs, which is considered underweight.
Health Risks of Being Underweight
It is not just obesity or being overweight that can cause health problems. Being in the underweight category can also put you at risk for certain ailments. People who are underweight are at risk of suffering from health issues such as:
- – Nutritional deficiencies
- – Weakened immune system
- – Fertility problems
Tips to Gain Weight and Increase Your BMI
If you are underweight and need to put on some pounds to get up to a healthy weight level, the main ideas are the same as for weight loss. You need to consume a more thoughtful diet and exercise in the right way. Here are 3 quick ways to start to gain healthy weight and increase your BMI.
1. Consume More Than You Burn
The secret to gaining weight is simple. You need to consume more calories than you burn. While that sounds easy, it may not be for some people whose bodies burn a lot of calories. Keep track of the calories when you eat and set a goal of consuming 500 – 1,000 more a day. This will put you on track to gain a healthy 1-2 pounds a week.
2. Don’t Just Eat More, Eat More Often
It is easier to eat small meals than big meals so you will not feel stuffed. If you eat 4 – 5 meals a day, it will be much easier to consume the extra calories you need. Just be careful of the kind of calories you take in. Foods that are high in protein, carbs, and healthy fats are much better than empty calories from junk food.
3. Lift Big
Skip the cardio and even the sculpting type weight lifting like curls. You need to go right to the heavy, high-muscle building activities like bench press, deadlifts and squats to put on dense muscle.
