Portion Control
Managing the amount of food you eat at each meal, a proven behavioural strategy for reducing calorie intake.
Plain English
Patient-Friendly Explanation
Portion control means being mindful of how much food you put on your plate, rather than eating directly from packages or oversized restaurant servings. Simple strategies include using smaller plates, measuring servings, and filling half your plate with vegetables — all of which help you eat fewer calories without feeling deprived.

Clinical Definition
Portion control is a dietary self-monitoring strategy that involves moderating the quantity of food consumed per eating occasion. Research demonstrates that portion size is a powerful environmental determinant of energy intake — larger portions increase consumption by 30–50% regardless of hunger levels, a phenomenon known as the portion size effect. Structured portion control is a core component of behavioural weight loss interventions and is associated with sustained caloric deficit.
Key Insight
Why It Matters
In Singapore's food culture, where eating out is common and restaurant portions have increased substantially, portion control is one of the most practical tools for weight management. It allows patients to enjoy local foods while maintaining a caloric deficit — a cornerstone of Dr Wang's personalised weight loss plans.
