Jane Litfin

Gym Geek’s health and fitness editor.

Hello! I'm Jane Litfin, health and fitness editor, writer and researcher. As Gym Geek's editor, I oversee our weight management guides, expert workout routines and exercise guides. I'm passionate about evidence-based weight management and strength training, with a talent for simplifying complex scientific topics into clear, practical advice for dieters and fitness enthusiasts.

In addition to my role at Gym Geek, I also advise other Recoreo brands and have previously contributed to Mamene.co.uk, a weight loss and calorie counting app. Prior to my role here, I also made freelance contributions to health and fitness publications in the United Kingdom and Canada.

My Expertise & Background

My writing is driven by a deep interest in weight management and strength training, blending the most reliable scientific research with real-world experience. My expertise includes:

  • A degree in Sports & Fitness Management, giving me a strong foundation in exercise science and business management.
  • Completion of Nutrition Science: Obesity and Healthy Weight Loss with the University of Aberdeen, expanding my understanding of safe and sustainable weight loss.
  • Over 10 years of writing, research and editing experience tailored to dieters and gym-goers.
