This is the first tenet of the naturopathic oath we all take on graduation day from college, and the most critical.
As naturopaths we strive not to add to the burden of problems of our patients. To refrain from damaging their physical, mental, or emotional wellbeing. To not intervene in ways that harm.
In many ways, we are good at abiding by this foundational tenet...
- We know not to prescribe a herb that will interact dangerously with a client’s medication.
- We avoid recommending restrictive elimination diets when a gentler, more balanced approach will suffice.
- We double-check safety in pregnancy before recommending a herb or an essential oil
- We withhold a liver detox protocol when a client’s constitution is already depleted.
- We understand that sometimes less is more - that doing nothing is better than doing something that could cause harm.
And yet… there's something insidious going on within the naturopathic profession that has not been called out. Despite our best intentions, it's doing serious harm to our clients, our profession, and ourselves.
That thing is a weight-focused approach to health, also known as the weight-centric health paradigm (WCHP) (O’Hara & Taylor, 2018). Whether directly or indirectly, promoting weight loss does irrefutable harm.
Even if it’s weight loss “for health.” Or “for fertility.” Or just because “who doesn’t want to be a bit leaner?”
Rejecting Diets is Doing No Harm
Diets don’t just fail in the long run. They cause measurable harm.
- Metabolic harm: In the famous “Biggest Loser” follow-up study, participants showed a sustained metabolic slowdown of around 700 calories/day, persisting six years after the intervention (Fothergill et al., 2016). This adaptive thermogenesis increases the risk of weight regain and long-term metabolic disturbance.
- Weight cycling: Repeated weight loss and regain (very common after diets) increases risk of hypertension, insulin resistance, and cardiovascular disease - independent of BMI (Montani, Schutz, & Dulloo, 2015).
- Disordered eating: Dieting is one of the strongest predictors for the onset of eating disorders. Even “moderate” restriction can lead to binge-restrict cycles and clinical eating disorders (Stice, Marti, & Durant, 2011).
- Psychological harm: Dieting is associated with increased body dissatisfaction, food preoccupation, depression, and lowered self-esteem (Polivy & Herman, 1985).
- Nutrient deficiencies: Restrictive diets often reduce intake of essential micronutrients such as iron, calcium, and B vitamins (depending on which diet), particularly when multiple food groups are excluded (O’Hara & Taylor, 2018).
Given this evidence, how can we possibly collude with diet culture and still claim to practice do no harm? To prescribe or promote weight loss is not neutral; it is a harmful intervention that undermines health.
