Approximately half of obese individuals suffer from fatty liver disease. The liver synthesizes triglycerides, yet it possesses limited storage capacity for excess lipids. In obese individuals, the balance between triglyceride synthesis and transport becomes disrupted. High fatty acid intake leads to increased liver-synthesized triglycerides, causing massive accumulation within the liver. This accumulation ultimately results in fatty liver disease.
Gallstones
Low-calorie and low-fat diets for weight loss carry a risk of gallstone formation. This occurs because when fat and cholesterol intake suddenly decrease, causing hunger, the gallbladder cannot deliver sufficient bile to the small intestine. Bile stasis and supersaturated bile salts promote stone formation.
Increased Diabetes Risk
Obesity is a major risk factor for diabetes. Among type 2 diabetes patients, 80% are obese. Moreover, the longer obesity persists, the greater the likelihood of developing diabetes.
Causes Bone and Joint Diseases
Osteoarthritis, diabetic osteoarthropathy, and gouty osteoarthropathy. Among these, osteoarthritis is the most prevalent and harmful. Obesity-related osteoarthritis primarily affects the knees, followed by the hips and finger joints.
Cancer
Epidemiological studies indicate obese women face higher risks of endometrial cancer and postmenopausal breast cancer, while obese men are more prone to prostate cancer. Additionally, obesity increases susceptibility to colon and rectal cancer in both sexes. The severity of obesity correlates directly with higher incidence rates of these cancers.
Hair Loss
Recently, an increasing number of people have experienced hair loss due to dieting, with 20%-30% being young women aged 20-30. Since hair primarily consists of protein and trace elements like zinc, iron, and copper, individuals who diet by eating only plant-based foods may suffer from insufficient protein and trace element intake. This can lead to severe nutritional deficiencies in the hair, resulting in hair loss.
