The Shift

Gary Foster · 2023
83/100
👍 Worth It

Gary Foster brings genuine clinical credentials — decades of obesity research, Temple University's Center for Obesity Research, Chief Scientific Officer at WW — and the book reads like it. The seven mindset shifts are grounded in cognitive behavioral therapy rather than wellness trends, and the emphasis on self-compassion over willpower is both scientifically sound and genuinely useful for readers stuck in diet-culture cycles. A national bestseller that earns the attention.
