Dieting Makes You Healthier, But It Also Causes Depression
Controlling your diet and what you eat is one way to stay fit — and you would think that having a healthier body would leave you happy, or at the very least content with yourself. But a new study from researchers at the University College London have found that dieting leaves you more depressed.
“Resisting the ever-present temptations of unhealthy food in modern society takes a mental toll, as it requires considerable willpower and may involve missing out on some enjoyable activities,” said researcher and lead author Sarah Jackson in a university press statement. “Anyone who has ever been on a diet would understand how this could affect wellbeing. However, mood may improve once target weight is reached and the focus is on weight maintenance. Our data only covered a four-year period, so it would be interesting to see how mood changes once people settle into their lower weight.”
In the study, which was published in the journal PLOS ONE, people who lost weight were twice as likely to feel tired, lonely, and sad. The researchers note that one of the reasons is that the advertising world sends the message that people will be transformed when they lose weight and in most, if not all cases, that does not happen. The disappointment they feel after realizing that their life has not changed is what leads to the symptoms of depression.
“We do not want to discourage anyone from trying to lose weight, which has tremendous physical benefits, but people should not expect weight loss to instantly improve all aspects of life,” Jackson said. “Aspirational advertising by diet brands may give people unrealistic expectations about weight loss. They often promise instant life improvements, which may not be borne out in reality for many people. People should be realistic about weight loss and be prepared for the challenges.”
