Jenny Craig BMI Formula – Height and Weight

In the mid 1800s, Belgian astronomer, mathematician and statistician Adolphe Quetelet developed ‘social physics’ for measuring healthy weight. The theories were further developed in a 1972 paper by Ancel Keys, published in the Journal of Chronic Diseases. The term Body Mass Index (BMI) was coined at this time to simplify the relationship of height and weight for indicating relative obesity. The Jenny Craig BMI formula has been a transformative weight loss tool for decades, allowing anyone to ascertain their own BMI score prior to embarking on a tailored diet and exercise plan.

How does your weight and height affect your BMI?

As the term implies, body mass index (BMI) provides insight into satisfactory weight levels according to height. For most people carrying extra kilos, fatty tissue is the culprit, skewing BMI scores into overweight and obese territory. Losing excess weight results in diminished fatty deposits for better overall health and vitality along with improved appearances.

The Jenny Craig BMI formula uses a simple mathematical equation that takes both height and weight into consideration. If maths isn’t your forte, don’t fret as the Jenny Craig BMI calculator does the math for you. The result is your personalised BMI score and an opportunity for tailored weight loss for genuine improvement. Using height as an additional measurement tool provides insight into personal health that can’t be gained using bathroom scales alone. With BMI, people of both sexes of any height can better appreciate relative weight in comparison to others.

What is a healthy weight for your height?

BMI measurements are represented differently to weight in kilograms typical of most weigh scales. The Jenny Craig BMI formula provides a score that is relative to different weight categories, from underweight to obese. Scores can be viewed in table, chart or graph form, allowing individuals to understand exactly where they stand and the amount of weight loss required to reach healthy weight targets. Your BMI score will place you in one of the categories below.

  • 18.4 or less (underweight)

  • 18.5 – 24.9 (healthy weight)

  • 25.0 – 29.9 (overweight)

  • 30.0 or more (obese)

Underweight, overweight and obese people understand that weight and health issues go hand in hand. In most cases, the problems can be reversed and optimum health attained. Jenny Craig has been assisting men and women transform their health since 1983 by overseeing meal plans personally designed for every individual. BMI assessments are ideally used in tandem with portion and calorie-controlled Jenny Craig meals designed by celebrity chefs and prepared by qualified professionals.

What other factors influence the BMI formula?

BMI scores provide reliable measurements although the formula isn’t suitable for everyone. BMI isn’t an alternative to professional medical advice, particularly for people suffering serious illnesses or ailments. For people whose weight gain is primarily caused by fat however, BMI is an invaluable tool when used appropriately. Your BMI score provides superior insight to the bedroom mirror, allowing individuals to reach realistic weight loss targets according to natural body shape.

There are differences between women and men also, although the same BMI calculations are generally used for both sexes. Men naturally carry a greater percentage of muscle than women, and an honest appraisal of your muscle/fat composition will assist when developing a weight loss plan. Growing children and teens can also use BMI charts coupled with percentile rankings that rate healthy weight status among peers of the same age and gender.

BMI isn’t suitable in most cases for pregnant women, the elderly and muscular athletes, while certain ethnicities such as Pacific Islanders exhibit higher BMI scores on average than other groups. BMI remains incredibly useful, and when overseen by Jenny Craig, a tailored weight loss plan can be put in place for satisfying, successful, stress-free results.
