David John Castañeda was just 19 years old when he reached 464 pounds, around 210 kilos. On a typical day, he started with an omelet made with eight eggs, cheese, ham, and bacon, and that was just breakfast.

Afterward, he could eat an entire package of pasta, numerous slices of bread, and amounts of rice that he himself described as enough to “feed a village”. He ate until he felt pain and came to think that his body would not hold out much longer.

Nearly three years later, his appearance is completely different: he says he has lost 273 pounds, around 124 kilos, without using weight-loss injections. After trying different methods, he now maintains a calorie deficit, tracks his macronutrients, and trains regularly.

Now, at 22, he works as a weight-loss coach and uses his own transformation to help other people.
