For sustainable weight management, which deficit is typically recommended?

• A. Severe restriction of 40% below maintenance
• B. No deficit
• C. Very aggressive weekly weight loss
• D. A moderate deficit through portion control and increased activity

Answer: (D)

A modest energy deficit is the best approach for sustainable weight management. When you combine sensible portion control with increased activity, you reduce daily calories enough to lose fat while still meeting your nutrient needs, keeping hunger, energy, and mood more manageable. This balance supports adherence over the long term, which is crucial for lasting results and preventing rebound weight gain. In contrast, extreme restriction is hard to maintain, can cause fatigue and nutrient shortfalls, and often leads to loss of lean mass and a stalled or reversed pace of progress. No deficit means no real weight change, and trying to lose weight too quickly is unsafe and unsustainable.
