Mallory King is a 27-year-old certified trainer and nutritionist with her own wellness blog, but she wasn’t always this focused on being healthy. She shares with POPSUGAR that she remembers being overweight ever since she was in elementary school. She was constantly teased about her weight, she said, and heartbroken about it. It wasn’t until a doctor warned her at age 16 that she was “on the road to obesity” that she started her weight-loss journey and taking better care of herself.
