From TikTok glow-ups to viral transformation videos, looksmaxxing has become one of the internet’s fastest-growing self-improvement trends. But how much of it is grounded in science and how much is extreme advice disguised as optimisation? As a registered dietitian, I’m seeing increasing numbers of young adults turning to restrictive dieting, supplement stacks, and unrealistic standards in pursuit of aesthetic perfection. In this article, you’ll learn what looksmaxxing really means, the hidden risks behind the trend, and 10 evidence-based strategies to improve your appearance safely and sustainably.
What is looksmaxxing?
Looksmaxxing is an online term used to describe efforts to maximise physical attractiveness. It typically includes skincare, grooming, fat loss, muscle gain, orthodontics, and fashion. In more extreme online communities, it can also involve aggressive dieting, unregulated supplements, and cosmetic procedures.
At its healthiest, looksmaxxing simply means taking care of yourself. However, some corners of the internet promote rigid beauty standards and quick-fix interventions that lack clinical evidence.
From a healthcare perspective, sustainable aesthetic improvement is rooted in physiology. When nutrition, sleep, movement, and mental well-being are optimised, physical appearance often improves as a secondary benefit.
Why is looksmaxxing trending now?
Short-form video platforms have intensified comparison culture. Algorithm-driven content repeatedly exposes users to curated and filtered appearances, creating unrealistic expectations.
Emerging discussions around social media and body image have highlighted how digital comparison impacts confidence and self-worth.
Research links high social media exposure with increased body dissatisfaction, particularly among adolescents and young adults. The National Institute for Health and Care Excellence guidance on eating disorders warns that dieting behaviours driven by appearance rather than health can escalate into disordered eating patterns. Self-improvement becomes harmful when it is rooted in shame rather than well-being.
The risks of extreme looksmaxxing advice
Before discussing healthy strategies, it is important to recognise common red flags seen in online glow-up culture:
Severe calorie restriction
Elimination of entire food groups without medical indication
Excessive reliance on supplements
Use of unregulated fat burners
Compulsive exercise
Obsessive body checking
The British Dietetic Association frequently cautions against fad diets and unregulated supplement marketing, particularly those promoted online.
Extreme approaches may produce rapid aesthetic change, but they often disrupt hormones, reduce metabolic rate, affect mood, and increase the likelihood of rebound weight gain. True optimisation protects long-term metabolic and psychological health.
Looksmaxxing vs. Healthmaxxing
A more sustainable framework is what I call healthmaxxing, prioritising internal health first. Improved skin clarity, better muscle tone, stable weight, and stronger hair are often visible outcomes of:
Adequate nutrient intake
Structured resistance training
Quality sleep
Stress regulation
Rather than chasing aesthetic perfection, focus on improving biomarkers, energy levels, and resilience. Appearance becomes a by-product of physiological balance.
10 evidence-based ways to improve your appearance naturally
1. Prioritise adequate protein intake
Protein supports muscle maintenance, collagen production, wound healing, and hair structure. For most adults, 0.8-1.2 g per kilogram of body weight per day is appropriate, with higher needs during resistance training.
Distributing protein evenly across meals improves muscle protein synthesis and contributes to a firmer, more toned appearance over time.
2. Support skin health with omega-3 fats
Omega-3 fatty acids have anti-inflammatory properties and contribute to skin barrier integrity. Oily fish such as salmon, sardines, and mackerel are key sources.
The NHS healthy eating guidelines recommend at least one portion of oily fish weekly. Plant sources such as flaxseed and walnuts provide alpha-linolenic acid, though conversion rates are lower
3. Do not eliminate carbohydrates unnecessarily
Very low-carbohydrate diets are common in online transformation advice. However, carbohydrates support thyroid function, training performance, and mood regulation.
Whole grains, fruits, and legumes provide fibre and antioxidants that support gut health, and the gut-skin axis is increasingly recognised as a contributor to skin clarity.
4. Check iron and B vitamin status if symptomatic
Hair thinning, brittle nails, fatigue, and pale skin can indicate micronutrient deficiencies. Iron deficiency is particularly common among women of reproductive age.
If symptoms are present, testing through your GP is preferable to self-supplementation. Food-first strategies remain the safest approach.
5. Hydrate consistently throughout the day
Chronic dehydration can exacerbate dull skin and fatigue. Regular fluid intake supports circulation and skin elasticity. Aim for pale yellow urine as a practical hydration marker rather than relying on arbitrary water targets.
6. Strength train to improve body composition
Muscle mass significantly influences overall body shape and posture. Two to three structured resistance sessions per week can meaningfully improve body composition.
Strength training enhances insulin sensitivity, bone density, and long-term weight stability, all of which contribute to sustainable aesthetic change.
7. Protect sleep quality
Sleep deprivation elevates cortisol and disrupts appetite-regulating hormones. It also contributes to dark circles, reduced skin repair, and increased cravings. Most adults require 7-9 hours of consistent sleep for optimal physiological function.
8. Increase antioxidant intake
Fruit, vegetables, nuts, and seeds provide vitamins C and E, polyphenols, and carotenoids that support cellular protection.
The World Health Organization's healthy diet recommendations advise consuming at least 400 g of fruit and vegetables daily to reduce chronic disease risk, and these same foods support skin vibrancy.
9. Be cautious with beauty supplements
Collagen powders, high-dose biotin, and “detox” teas are heavily marketed in glow-up culture. Evidence remains mixed, and excessive supplementation can interfere with laboratory testing or cause adverse effects. Dietary adequacy should always be assessed before investing in supplements.
10. Improve posture and body language
Confidence, posture, and grooming strongly influence perceived attractiveness. Strengthening the posterior chain, reducing prolonged sitting, and maintaining neutral spine alignment can subtly but significantly change how you present physically. Confidence is often behavioural before it becomes emotional.
When to seek professional support
If looksmaxxing behaviours lead to:
Food anxiety
Social withdrawal
Compulsive training
Rapid weight fluctuations
Obsessive body checking
It may be time to seek support from a GP, registered dietitian, or mental health professional. Early intervention prevents long-term complications
Start your journey with science, not extremes
Improving your appearance does not require starvation, punishing workouts, or expensive supplement stacks. It requires consistency, nourishment, and respect for your physiology.
