Unless you're Michael Phelps or an olympic athlete burning 6000 calories a day training.
But Colin007 is right. Caloric deficits are the only way you're going to lose weight. You shouldn't starve yourself, but you shouldn't be eating 6000 calories a day either.
The biggest thing is finding the tools/motivation that works for you. Mine was medical issues(HBP), I'm down 53lbs since January and use intermittent fasting and calorie counting to lose weight. Within 10lbs of my goal weight. I did use Keto for the first 25 lbs. but was concerned about the fat levels and my liver enzymes.
