Fat and body function

Fat is not just a passive storage of calories. It's an active organ that produces hormones and neurotransmitters that affect many processes in the body. Excessive levels of body fat can disrupt these signals and lead to health challenges.

Health complications

When the body carries extra weight, it can lead to a number of health challenges, including heart disease, type 2 diabetes and certain types of cancer. These conditions can worsen if the excess weight is not managed effectively.

Genetics and the environment

While some people are genetically predisposed to have a higher body weight, environment also plays a big role. This includes diet, physical activity and even the social environment, which can influence our eating and exercise habits.

Mental aspects

Being overweight can also have psychological effects. Some people may experience low self-esteem, depression or anxiety due to their weight. It's important to address these feelings and seek support if needed.

Treatment options

There are many ways to manage obesity, from diet and exercise to medication and surgery. The best approach depends on the individual's situation and needs. A healthcare professional can provide guidance on the most effective strategies.

Prevention and lifestyle

Preventing or managing obesity often requires lifestyle changes. This can include healthier eating habits, regular exercise and stress management. These habits can not only help with weight management, but also improve overall wellbeing.
