In this short talk, Eric Roberts explains that the most challenging phase of a weight‑loss journey often comes after the scale finally stops dropping. While people are losing weight they receive frequent dopamine hits from seeing the scale go down, clothes fitting better, and compliments from others. When the weight stabilises, those rewards disappear, leading to feelings of doubt and a sense that something is wrong. Roberts argues the solution is to incorporate regular weight‑lifting, because strength training provides continual, measurable progress—adding a few pounds to the bar or a few extra reps each week— which restores the dopamine feedback loop and keeps motivation high even after weight loss plateaus.
