Plant-Based Diets for Weight Management

A plant-based diet focuses on foods from plants — vegetables, fruits, whole grains, legumes, nuts, and seeds — while reducing or eliminating animal products. These foods are naturally lower in calorie density and higher in fibre, which helps you feel full on fewer calories. Studies show that people who follow plant-based eating patterns tend to have lower body weight and find weight loss easier to sustain.

Plant-based dietary patterns — ranging from flexitarian to vegan — are characterised by high intake of minimally processed plant foods and low energy density, typically 0.6–1.2 kcal/g versus 2.0–4.0 kcal/g for animal-based and ultra-processed foods. The weight-management benefits are mediated through multiple mechanisms: increased dietary fibre promoting satiety via slowed gastric emptying and GLP-1/PYY release, lower fat and higher water content reducing caloric density, favourable gut microbiota modulation increasing short-chain fatty acid production, and improved postprandial insulin sensitivity.

Singapore’s diverse food culture — from economical rice to hawker centre favourites — makes plant-forward eating both accessible and culturally compatible. Dr Joseph Wang at Accord Medical can guide you on incorporating more plant-based meals into your weight management plan without sacrificing the flavours you love.
