You Shall Not Make For Yourself a Weight Loss Idol

As the second commandment indicates, we humans have a powerful tendency to make and worship idols. That tendency does not stop at the spiritual realm. It shows up in how we picture the body we are trying to build.

Resist the temptation of carved images

In a media-saturated culture, we set ourselves up for failure by wanting to be somebody else — or at least to have somebody else’s body. We forget that each of us is unique, in height, in build, in personality and in talents.

Do not misunderstand me. There is a real aesthetic dimension to appearance, and body weight contributes to it. There is nothing wrong with having role models, or with having goals. But it matters enormously that the goals be realistic. It is not realistic to hope for a 30-inch waist when you are starting at 45.

Ten years after I first wrote this, the idols have changed. They are no longer only magazine covers and film stars; they are filtered, edited and increasingly synthetic images on a phone screen, delivered by an algorithm that has learned exactly which ones hold your attention. The research on this is now reasonably clear — exposure to idealised body imagery on social media is associated with greater body dissatisfaction, particularly in young women.³ The commandment has aged rather well.

What a realistic goal actually looks like

Most people beginning a weight loss programme have goals that cannot be met. A classic study of obese women entering treatment found that, on average, they hoped to lose 32% of their body weight. Their “dream” figure was 38%. They would be “happy” with 31%, would “accept” 25%, and would be “disappointed” with 17%.

After 48 weeks of treatment, 47% of them had not reached even their disappointing figure.¹ Not because the treatment failed — many lost meaningful weight — but because the target was set where almost nobody lands.

I know this sounds modest, and for some readers it will sound disappointing. Two things are worth holding onto. First, you do not stop at six months. Second — and this is the part that surprises people — the health benefits of a 5 to 10% loss are substantial and well documented:

• Blood pressure, cholesterol and insulin resistance all improve, and the risk of developing type 2 diabetes falls
• Tissue inflammation decreases
• Heartburn and reflux symptoms often resolve entirely
• Fatty liver improves
• Weight loss is the single most effective lifestyle change in obstructive sleep apnoea
• As little as 5% brings significant improvement in pain and function in knee arthritis

The Diabetes Prevention Program remains the cleanest demonstration. A lifestyle intervention targeting just 7% weight loss reduced progression to type 2 diabetes by 58% — considerably better than metformin in the same trial.² Seven percent. Not thirty-two.

There are plenty of reasons to celebrate what looks, at first glance, like only modest weight loss.

A note on the new medications

Something has changed since I first wrote this article, and it deserves an honest mention. The GLP-1 receptor agonists now produce average weight losses of 15 to 20% in trials — figures that were unreachable with lifestyle intervention alone and that sit much closer to what patients always said they wanted.

This does not retire the commandment. It relocates it. The idol was never really a number; it was the belief that a particular body would solve something. And the same questions apply to a patient on semaglutide as to one on a diet: what happens when the medication stops, what have you built in the meantime, and are you chasing health or chasing an image? If you are considering these drugs, that is a conversation for your own doctor — but bring the second commandment with you into it.

One more word about weight loss idols

The most destructive idol is not a celebrity. It is a version of yourself from twenty years ago, or a number on a scale that you have decided is the price of self-respect. That idol cannot be appeased. Set a target you can reach, reach it, then set the next one.
