Antonio Gutierrez still remembers the day he came back from the amusement park in tears. He was about to climb the roller coaster, but when he went to sit down, the safety harness did not close. "I had to get up and get out of the merry-go-round because I was too big," he said.This episode was the first of a series of turning points that convinced Gutierrez that it was time to be in good health. " Another serious incident took place at the airport, "he continues." I got on my plane and the belt did not want to close completely. I had to suck as much as possible my stomach for the plane to take off. I delayed the flight because I could not buckle my seatbelt. "

Gutierrez, now 28, who works as a store manager for a supermarket in Gardena, California, says he weighed nearly 355 pounds at its heaviest point. He was 27 years old and was suffering from both depression and suicidal thoughts. "I did not want to leave my house or talk to anyone, not even my wife or my son, I wanted to stay away from everyone and I hated taking pictures," he says. For Gutierrez, the seriousness of his situation really sank into an afternoon while he was playing with his four-year-old son. They were continuing in the house when Gutierrez, out of breath, had to stop. "Then I realized that I had to make a change," he says.

Until then, Gutierrez said that his diet was the main cause of his weight gain: he ate more than 8,500 calories a day, he said, the essential from food sweet and non-alcoholic drinks. "I would drink a two-liter container of soda for dinner alone, I would go home and watch TV with a big bag of potato chips and a plate," he says. "I can not explain how horrible I felt, just thinking about it scares me now."

Gutierrez had heard about the keto diet – which involves driving your body to burn fat as the main source of energy – and had decided to try it in December 2018. He had also decided to associate it with intermittent fasting, a diet that typically consisted of eating for eight hours and fasting for 16 hours on a given day. To stay consistent, he used an app – the LIFE Fasting app – in order to track the timing of his meals and determine when his body was in a state of ketosis, the stage of fat burning.
