Body Adapts Gradually Causing Plateaus
- Weight loss usually tapers gradually as the body adapts rather than stopping suddenly.
- Dr. Stephen Cabral describes typical weekly losses falling from ~2–3% to ~0.2–1% as metabolism downregulates over time.
Quitting Often Causes Rebound And Lost Muscle
- Stopping after losing 15–20 pounds often leads to regaining weight and losing muscle and bone mass.
- Cabral warns that quitting without resistance training makes the initial losses harder to maintain and may cause rebound gain.
Lower Calories Trigger Metabolic Slowdown
- Eating fewer calories lowers metabolic rate as the body reduces thyroid, testosterone, and DHEA production.
- Cabral explains a 2,000 kcal baseline can shift down (e.g., to 1,600 kcal), so the same intake stops producing weight loss.
