In this YouTube video, Eric Roberts recounts a two‑week self‑experiment where he ate at a 1,000‑calorie daily deficit. During the first week he experienced rapid weight loss, with the scale showing new lows each day. In the second week, despite continued weight loss, he noticed a sharp decline in workout performance, loss of strength and muscle, constant hunger, and zero energy. Frustrated, he increased his intake to a 500‑calorie deficit for the remainder of the experiment. The slower deficit resulted in a more moderate weight loss rate but restored energy levels, improved workout quality, and felt far more sustainable. He concludes by advising viewers to avoid extreme deficits and instead adopt a moderate, sustainable calorie reduction to maintain weight loss long‑term.
