How Much Should You Weigh?

Many of us have a preconceived idea of how much we should weigh.  What prompts us to arrive at that number?  Do you want to lose “x” amount of weight so you can weigh what you weighed in college?  Or, have you arbitrarily assigned yourself a number?  Because there isn’t an ideal number, we’re left to decide for ourselves.  Using body mass index (BMI) gives you a general guideline for how much you should weigh.

BMI is not without it’s faults, but it is a simple method to determine body mass based on weight and height.  Physicians use the number as a risk factor for developing obesity-related diseases such as diabetes and heart disease.  BMI is classified the following ways:

Underweight:  <18.5
Normal weight:  18.5 – 24.9
Overweight:  25 – 29.9
Obesity:  >30

Click here to discover your BMI using the American Council on Exercise (ACE) web-based BMI calculator.

If you fall outside of the “normal weight” category, don’t fret.  Losing as little as five pounds could improve your score.  Dr. Cedric Bryant, ACE’s Chief Science Officer, states, “The key point to keep in mind is that to determine their ideal body weights, individuals should not rely solely on a bathroom scale, height-weight tables, BMI or even percent body-fat measurements. Sound nutrition and exercise science principles, along with common sense, mandate that individuals should avoid setting “hard and fast” body-weight goals. Rather, they should strive for achieving a level of body weight that is compatible with a healthy lifestyle (e.g., sensible eating, regular exercise).”


Jillian Michaels Gets Sued: From A Trainer’s Perspective

Jillian Michaels is being sued for false advertising.  If the name doesn’t ring a bell, she’s one of the personal trainers on the TV show “The Biggest Loser.”  Michaels endorses the diet supplement Jillian Michaels’ Maximum Strength Calorie Control as well as other supplement products.  “Sadly, Michaels has decided to exploit her fame and goodwill by collaborating with Thin Care and Basic Research to promote a weight loss supplement that purportedly will cause weight loss by itself, without any additional effort on the part of the consumer,” the lawsuit alleges.  The plaintiff is seeking to prohibit the sale of the product as well as damages.

Before you start calling the plaintiff names, consider that these products exist because people do buy them.  There are those that truly believe there is a miracle pill.  Many people respect Jillian for the work she’s doing on the reality TV show.  So, why not trust her when she says a supplement will help you lose weight?

My biggest issue with this is Michaels has stepped outside of ethical practice for personal trainers.  Respectable trainers do not recommend supplements.  It is outside our scope of practice.  We know that pills do not cause you to lose weight.  It is the job of nutritionists and registered dieticians to prescribe foods.

Many fitness professionals are members of the group IDEA Health and Fitness Association.  The IDEA Code of Ethics for Personal Trainers states, “As a member of IDEA Health & Fitness Association, I will be guided by the best interests of the client and will practice within the scope of my education and knowledge. I will maintain the education and experience necessary to appropriately train clients; will behave in a positive and constructive manner; and will use truth, fairness and integrity to guide all my professional decisions and relationships.

‘Always be guided by the best interestes of the client.

Remember that a personal trainer’s primary responsibility is to the client’s safety, health and welfare; never compromise this responsibility for your own self-interest, personal advantage or monetary gain.

Recommend products or services only if they will benefit the client’s health and well-being, not because they will benefit you financially or occupationally.'”

I believe Jillian knows better, but money talks.  The take home message:  Weight loss pills DO NOT work.  Do not buy them.  Do not believe anyone, even if it’s your personal trainer, who suggests using them.

Healthy Body Fat Percentages

I just read an article that was promoting a workout routine in which a client had “literally lost 100% of their body fat.”  This is not only extremely unlikely, but completely irresponsible of the author!  Please, I beg you, if you see these programs being advertised, run.  We’ve all heard the message that fat is bad.  So, now we’re pursuing ways to lower our body fat percentages.  And, with the obesity rates in America, we should be concerned about losing fat.  But, to the point where you have none is ill-advised.  Having some fat is good.

Lots of research is being done about the benefits of having fat.  What we know is that fat cushions the organs, helps regulate body temperature, contributes to metabolism, and provides an energy source for the body.  Fat also is the home for the hormone adiponectin.  Adiponectin is a beneficial hormone which reduces cell inflammation and improves HDL, the good cholesterol.  It’s when there is too much fat that it causes problems.

So, what is a healthy body fat percentage?  Well, it differs between men and women.  The American Council on Exercise (ACE) provides this table.  Women should be in the range of 21-31%.  Men, 14-24%.  Notice the classification of “essential fat.”  Yes, some is essential.  Even athletes are encouraged to have body fat.

Please look to reputable sources like ACE and the American College of Sports Medicine for recommendations about fitness.  For more information about fat and losing weight, read these posts.
