Has Optimisation Culture Gone Too Far? | Sarah Ann Macklin

What It Covers

Registered nutritionist Sarah Ann Macklin, founder of the Be Well Collective, argues that the $8.5 trillion wellness industry is producing sicker, more anxious people because it ignores the foundational variable underneath all health practices: the quality of the inner dialogue driving them, and the level of self-compassion a person brings to their own health behaviors.

Key Questions Answered

• •Perception shapes physiology: Three studies demonstrate that mindset directly alters biological outcomes. The Stanford Milkshake Study showed that believing a 300-calorie shake was indulgent versus diet produced measurably different hunger hormone responses. Harvard's chambermaid study found hotel workers who were told their daily tasks equaled gym exercise lost 10% body weight and reduced blood glucose — without changing behavior.
• •Self-compassion vs. self-esteem: Self-esteem fluctuates based on comparison to others, making it an unreliable health metric. Self-compassion remains stable regardless of external benchmarks. Macklin recommends applying the "friend filter" — before acting on self-critical thoughts, ask whether you would direct that same language toward a close friend. Most people would not, revealing a correctable double standard.
• •Three-stage compassionate decision framework: When facing health decisions, Macklin applies a sequential process: first, self-empathy (check hunger signals, drink water, ask whether the choice serves you); second, mindfulness (take deep breaths to engage the rational brain and avoid reactive low-road decisions); third, shifting into resilience by choosing the long-term beneficial option over the immediate dopamine response.
• •Name your inner critic: The inner critic is typically not your own voice — it originates from a former caregiver, partner, or authority figure embedded in the subconscious. Macklin recommends assigning it a distinct name to create psychological dissociation. Once named, negative thoughts can be acknowledged, thanked, and consciously dismissed rather than unconsciously obeyed, accelerating the development of self-compassion as a trainable skill.
• •GLP-1 medications require mindset intervention: Eighty percent of GLP-1 users regain weight within twelve months of stopping, and 40% of weight lost includes muscle mass. Macklin argues this reflects the absence of inner dialogue work alongside the medication. Without addressing the self-critical patterns that drive eating behavior, hunger signals return unchanged and the underlying psychological drivers simply redirect toward new targets like body dysmorphia.
• •Wearables can increase health anxiety: A condition called orthosomnia — documented in people using sleep-tracking wearables — shows that over-reliance on devices to define how one feels increases health anxiety rather than reducing it. Macklin recommends reviewing wearable data once weekly as a reference point rather than allowing real-time metrics to override internal body signals, which remain the more reliable and accessible primary data source.
