The influence of social media on body image and eating behaviour

May 20

Social media is a double-edged sword. Simply put, what we consume often shapes how we think, behave, and even how we eat. It can help us grow or slowly harm our mental and physical well-being. The choice often depends on how we use it and the kind of content we engage with. Have you ever wondered why people mostly tend to show their positive side on social media? Perfect selfies, glowing skin, healthy meals, and ideal lifestyles flood our feeds every day. Rarely do we see the struggles, failures, insecurities or emotional breakdowns behind those posts. Why people rarely share their unhappy moments? The answer is simple; they do not want to be judged or criticized. This is why believing everything that we see on social media gives us only half picture. We need to understand that there is a bigger picture hidden behind the screen. What we see or follow on social media decides mainly what decisions we take, for example if you follow someone documenting their weight loss journey, we would probably get inspired to copy their diet, exercise routine, or even medication. However, what we don’t see is the reason behind the transformation, the medical condition, the body type, access to healthcare, stress levels or personal environment. Blindly following trends without understanding the individual differences can negatively affect both body image and eating behaviour. Constant exposure to unrealistic beauty standards may lead people to feel dissatisfied with their appearance, develop low self-esteem or adopt unhealthy eating habits in an attempt to look perfect.

The culture of “perfect image” on social media

Perfect image has become a growing trend nowadays. People often follow unverified diets, wear body tightening garments, or even undergo risky cosmetic procedures just to achieve the so called “perfect look”. There is so much pressure to look attractive that quick results are valued more than genuine health and well-being. People prefer instant transformations without understanding that it demands investing time in physical activity, stress management, balanced diet and overall healthy life style habits.

Social media platforms are filled with edited versions of people’s daily lives which gives a false sense of hope to those who follow them. They start to compare themselves with so- called influencers, celebrities, or even to their peers online. This comparison creates a sense of insecurity and pressure to change one’s appearance in unhealthy ways. Over time, this desire to achieve a perfect image may negatively impact both body image and eating behaviour.

Impact of social media on body image and eating behaviors

Depending upon the type of content, social media can have both positive and negative impact. Research has found that social media is a risk factor for development of eating disorders. One survey also found that there was a link between social media use and signs of negative body image. A study on TikTok and diet culture found that popular TikTok content often promotes disordered eating habits to viewers, presenting thinner body types as more ideal, often known as “thinspiration”. Social media exposes users to such content that leads to body dissatisfaction, anxiety, and depression. One study of teen girls found that the more time they spend using social media, the more likely they are to experience body dissatisfaction and even depression. Teens are not the only victims of social media; everyone is prone to concerns about their appearances or having certain features they wish they could change. Excessive and uncontrolled use of social media has been associated with various health problems, including disordered eating behaviors. The frequent sharing of food related content and advertisement for unhealthy foods on social media can adversely influence individuals’ eating behavior. Though, social media also presents positive opportunities for health professionals and public institutions to promote healthy lifestyle and raise awareness among individuals. But many a times, unscientific and unverified content with a catchy title gains more views than those coming from the experts.

The algorithm trap

The algorithm makes it worse by showing the content that a person once searched again and again. Someone who watches one weight loss video is served dozens more. Over time, this constant exposure can reinforce insecurities and unhealthy beliefs about body image and food. Algorithms are designed to keep users engaged for longer periods, as a result the users may unintentionally become trapped in cycles of comparison, self-criticism and unhealthy eating behaviors.

Not all social media is harmful

Although social media is often criticized as promoting harmful content, but it also carries genuine potential for good. Social media can be used as a powerful platform to spread awareness about mental health, body positivity, balanced nutrition, and healthy lifestyle. A study found that body positive movements on social media advocate for diverse body acceptance and challenge unrealistic beauty standards. Research has found that eating disorder awareness campaigns on social media can help reduce stigma and promote early detection and treatment.

How to use social media effectively?

Limiting your time on social media can reduce the engagement in harmful eating habits and might boost your body image. A study found that students who halved their social media usage for a few weeks experienced improvements in their body image. Social media usage can be limited by following ways:

Deleting social media applications particularly image-based platforms, like Instagram, and TikTok and accessing them through browser when needed.
Turning off social media notifications.
Monitoring your screen time and setting limits.
Cultivating hobbies that do not require you to use phone, for example, gardening, meeting friends, or going for a walk.

Social media is both a boon and bane. While it helps us to connect, inspire, get awareness on different topics of interest. It can also expose us to such content that can negatively impact our both physical and mental well-being. Therefore, it is essential to use social media mindfully, and consume content critically. We must remember that what we see online is often a carefully edited version of reality.
