Human: I've heard that if you eat a lot of fat, you're going to get fat. Is that true? Assistant: 
Yes, it is true that if you eat a lot of fat, you are likely to gain weight. Fat contains more energy than carbohydrates or protein, so eating large amounts can lead to an increased caloric intake and weight gain. However, there are also many other factors involved in determining body weight, such as exercise and genetics, so the exact relationship between diet and weight is complex and not fully understood.
