Environmental toxins, such as endocrine-disrupting chemicals found in plastics, pesticides, and industrial products, have been increasingly linked to obesity. These toxins can interfere with hormone regulation, affecting processes such as fat storage, appetite control, and metabolism. Exposure to chemicals like BPA (bisphenol A) and phthalates, particularly during critical periods of fetal development or early childhood, may increase the risk of developing obesity later in life. These toxins can alter the way the body stores fat, leading to excessive weight gain. To reduce the risk of obesity caused by environmental toxins, it is important to minimize exposure by using safer, non-toxic products, supporting policies to regulate harmful chemicals, and promoting healthier lifestyles. Reducing toxic exposure is a key component in preventing obesity and improving public health.
