How to measure your body shape

There are many ways to calculate your size and weight. Weight is easy with a scale but the way to measure your size is usually done using the Body Mass Index, a measurement I have never been a big fan of. Here is that and more. This info is from Health Canada but even if you are not a Canadian I think it is still relelvent.

Body Mass Index
The body mass index (BMI) assesses body weight relative to height. You can calculate your BMI by taking your weight in kilograms and dividing

it by your height in metres squared (BMI = kg/m2) or your weight in pounds divided by the square of your height in inches and multiplying that number by 704.5 (BMI = Ib/in2 x 704.5). But you don’t need to do the math yourself. You can check your BMI on a standard BMI table found in many pharmacies and medical offices. If you have access to the Internet, there are many interactive BMI calculators that will do the math for you after you enter your height and weight.

How to measure your body shape

Once you know your BMI, you can use it to help determine how healthy your weight is in relation to your height.

  • BMI below 18.5 is considered underweight.
  • BMI between 18.5 and 24.9 is considered the normal, healthy range.
  • BMI between 25 and 29.9 is considered over­weight.
  • BMI over 30 is considered obese.

The BMI is only one indicator of a healthy weight. It has limitations and does not apply to children, pregnant women, or people with very muscular bodies. If your BMI falls outside what is generally considered healthy, ask your doctor what would be a healthy range for you.

Hip-to-Waist Ratio

Fat stored around the abdomen (the “apple­shaped” body) raises the risk of cardiovascular disease more than fat stored in the hip area (the”pear-shaped” body), so the hip-to-waist ratio (HWR) can be a useful tool in determining your risk of weight-related health problems.

To calculate your HWR, measure your waist at the smallest part-generally a few centimetres above your navel-then measure your hips at the widest point, including your buttocks. Now divide your waist measurement by your hip measurement to determine your hip-to-waist ratio.

Women with an HWR greater than 0.8 and men with an HWR greater than 1 .0 have a higher risk of developing heart disease and type 2 diabetes and should try to reduce their abdominal body fat.

Waist Circumference

Another easy tool for determining if your weight is in the healthy range is the waist circumference (WC). A WC of 88 cm (35 in.) or more in women or 102 cm (40 in.) or more in men carries a higher risk for health problems.

Achieving a Healthy Weight

To encourage healthy eating, Health Canada has developed Canada’s Food Guide to Healthy Eating, which outlines the four main food groups and explains which foods fall into which group and how many servings we should choose from each group every day. A copy of this guide is available at www.hc-sc.gc.ca/fn-an/food-guide­alimenVindex_e.html. Recently, the Food Guide was expanded to include a variety of multicultural variations. They are available in a number of languages at www.nutritionrc.ca/guide.html.

One of the keys to achieving and maintaining a healthy weight is portion control. A number of studies have shown that many people under­estimate the number of calories they consume daily, primarily because they don’t understand how much is in “a portion.” Here is a practical way of estimating the size of a portion of some common foods.

  • Vegetables fruit: about the size of your fist
  • Pasta or rice: about the size of one scoop of ice cream
  • Meat, fish, or poultry: about the size of a deck of cards or the size of your palm (without the fingers)
  • Cheese: about the size of a pair of dice or the size of your thumb from the tip to the base

Physical Activity

Although dieting alone can help you lose weight, adding exercise into your daily schedule can speed up the process. The goal of exercise in a weight loss program is to help burn more calories. Exercise itself, apart from its role in weight loss, has many health benefits-even for people whose weight is in the healthy range. But before you start any exercise program, check with your doctor to make sure that the activity you are planning is appropriate in terms of your age, overall health, and state of physical fitness.

The Limitations Of BMI


BMI is one of the most common tools for determining whether you’re too heavy in proportion to your height. Otherwise known as Body Mass Index, this is a calculation that helps to compare you to average weights and heights, to determine whether you’re in the normal range. It can vaguely tell you whether you have too much fat on your body.

The index can be very useful when deciding on what your ideal weight should be when you are trying to lose weight. However, as helpful as the BMI is, it also has its limitations. These are extremely important to know, as following BMI could actually sometimes take you in the wrong direction.

What’s Wrong With BMI?

There is no one scale that can truly determine what is the right weight for every single human on the planet. This is because everyone is different; people have different heights, weights, builds, activity levels, and so on.

When measuring one’s BMI index, the only two things that are taken into consideration are the height and weight of the person. Therefore, for those who have a big build or have a large amount of muscle mass, and those who those who are elderly and therefore have less muscle mass, the BMI scale is less dependable upon and can be very incorrect.


A person who has a larger amount of muscle mass is heavier, but this does not mean that the person has a larger amount of fat. Using BMI alone, you cannot determine if this person is actually normal or overweight.

Using Your BMI Measurement the Right Way

Therefore, when referring to the Body Mass Index to determine your ideal weight, do practice some common sense to decide what the right weight you should be aiming for is. If you have a larger build or are more muscular than most people, adding 10% to the ideal weight stated for your height is a more realistic aim. If you are of a smaller build, subtracting 10% off the stated weight can be your aim.

Measuring your body fat percentage is also a much clearer indication of whether you’ve got weight to lose. Even if you have a high BMI, having a healthy body fat percentage is what’s important to your health.

Besides doing this, keep an eye on how you feel when you get to a certain weight; if you have reached a certain weight but feel tired, fatigued, and generally feel you look too thin, then perhaps you have lost too much of weight and need to gain a little bit to be at the right weight.

Hopefully, you now know what the limitations of the BMI are and understand how you can get around these limitations. In the end, compared to weight, it’s your health that matters more; don’t set unrealistic targets for weight loss that will instead cause damage to your health and well-being.

How Do You Know When You’ve Lost Enough Weight?


Losing weight is often a long process and many people struggle on their journey. However, after reaching your earlier set goal weight, you may ask yourself; ‘Have I lost enough weight?â? When figuring out if you’ve lost enough weight, there are a few things you must consider such as your BMI, body type, and more.

First things first, remember that a doctor is the most qualified person to tell you if you’ve lost enough weight, especially if you’re doing so due to a health condition. If you want an idea at home, however, then here’s how to do it.

Check Your BMI

Although there are a number of limitations with BMI (Body Mass Index), it can be a useful measurement. To calculate your BMI, just divide your weight (in kilograms) by your height squared (in meters).

The normal range for your BMI would be between 18.5 and 25, but this may not apply to everyone. For instance, if you naturally have a big structure and heavy bones, your ideal BMI would probably be above 25, which actually makes you overweight by normal standards. On the other hand, if you have a small structure, your ideal BMI is probably lower than others.


Measuring Your Body Fat

Measuring your body fat percentage is another good way to make sure whether you’ve lost enough weight, and is more accurate than BMI. Always use this to verify that your BMI is telling the truth!

There are a few ways you can use to measure your body fat with the simplest method being using a skin fold caliper. You do this by pinching your fat (usually around your waist) and measure the thickness with a caliper. You then compare the measurement you get to a body fat percentage chart which you can easily find online. Alternatively, you can also use BIA (Bioelectric Impedance Analysis) where you step on a scale that then estimates your body fat percentage.

See How You Look And Feel

The best and simplest way to determine if you’ve reached your ideal weight is to just stand in front of a mirror and see how you look. If you have lost quite a bit of weight and you feel that you look good and healthy, then you probably are at your ideal weight. Ideally you should also not feel tired and must have enough energy to go through your day.

Of course, the main reason for you to lose weight should be to ensure your health is good, and that you feel good in yourself. Therefore, you can also decide to either stop or continue losing weight depending on how you feel health-wise.
