Social media, and especially trends like #SkinnyTok, have become part of everyday life for many women. They present “ideal bodies” that appear to be achieved effortlessly, creating intense pressure and constant comparison. Psychology and neuroscience show that these trends can reinforce mental health difficulties and eating disorders.
1. The Psychology of Comparison
Social comparison is natural, but when it happens constantly through images on TikTok, it activates cognitive biases:
The phenomenon of self-evaluation through images leads to reduced self-esteem.
Continuous exposure to “perfect bodies” reinforces mental patterns of self-criticism, which often lead to anxiety or depression.
Studies show that women who regularly view such images have a higher likelihood of developing eating disorders and experiencing emotional distress.
2. The Neuroscience of Body Image 🧠
Body image is not purely social—it also has a neurobiological basis:
The prefrontal cortex (PFC) processes social evaluation and can reinforce self-critical thoughts.
The insula and the amygdala are strongly activated in individuals with anorexia or bulimia when viewing body-related images, triggering intense feelings of distress and anxiety.
The dopaminergic reward circuit is involved in the vicious cycle of dietary restriction or binge eating: the “ideal body” becomes the reward, but not achieving it leads to stress.
3. Psychological Risk Factors ⚠️
Certain factors increase vulnerability:
Low self-esteem and linking personal worth to appearance.
Perfectionism, which is associated with an increased risk of eating disorders.
A history of school or social pressure, bullying, or body-related criticism.
4. Practical Prevention Strategies 💪
Psychoeducation: Understanding how social media influence the brain and emotions.
Separating self-worth from appearance: Structured work through CBT or mindfulness.
A healthy relationship with food: Focusing on nourishment and enjoyment, not restriction.
Support from your social network: Talking with friends, family, or a psychologist to reduce pressure.
5. Conclusions
Trends like SkinnyTok are not harmless entertainment: they can activate mechanisms of self-criticism, anxiety, and eating disorders. Understanding the psychology and neuroscience behind these phenomena is the first step toward body acceptance and mental well-being. The power lies in self-compassion, cognitive restructuring of negative thoughts, and the conscious selection of content on social media.
