301lb Man Loses 140lb in 10 Months Through Running and Meal Prep: ‘Be True to Yourself’ It became the lightbulb moment for him, making him realize that he needed to change his ways. To start shedding pounds, Conor Hegarty, 24, a management consultant, adopted a diet and lifestyle overhaul, including a gym regime, running, and meal preparation. Not even lockdown could slow him down; after 10 months, he had lost an incredible 42 percent of his body weight. Conor now hopes to continue his transformation by toning up even more. He wants to run his first marathon in June 2022. Conor told Men’s Health that he remembers always being heavy. Yet his weight gain “crept up” on him slowly.
