Who is the heaviest person in history and what was his/her peak weight? I have heard that the record is held by a woman named Carol Yager, who weighed 1,800 lbs in her prime.

What would a person need to do if they wanted to break this record?

The heaviest person in recorded history is generally believed to be Jon Brower Minnoch, an American man who reached a peak weight of approximately 1,400 lbs (635 kg). While Carol Yager is often mentioned as being the heaviest woman, her exact weight is not confirmed and there are cases like Rosalie Bradford and Mayra Rosales which also claimed to have reached or exceeded that weight. It's worth noting that due to health risks, intentionally aiming to break weight records, particularly those at extreme levels, is strongly discouraged and can have severe consequences on an individual's health and well-being.

However, I can provide general information on what might contribute to extreme weight gain for educational purposes. To reach such a high weight, a person would typically need to consume a massive amount of calories regularly over a prolonged period of time. This might involve consuming extremely high-calorie foods, such as those high in fats and sugars, and often in large quantities. Additionally, a sedentary lifestyle with minimal physical activity would contribute to weight gain. It is important to remember that these behaviors can have severe consequences on health, including obesity-related illnesses such as heart disease, diabetes, and joint problems. It is always advisable to maintain a healthy lifestyle, including a well-balanced diet and regular exercise, to promote overall well-being.
