Pulses and Weight Management
Pulses are the edible seeds of legumes such as lentils, chickpeas and dried beans, and their protein and fibre content makes them unusually filling for their calories.
Plain English
Patient-Friendly Explanation
Pulses are the dried seeds of the legume family: lentils, chickpeas, kidney beans, black beans, soybeans and dried peas. They contain both protein and a large amount of fibre, and the body digests them slowly, so a meal built around them tends to keep you full for longer than the same number of calories from white rice or white bread. They are also inexpensive and easy to find in Singapore. Adding about a cup a day, in dal, in soups, in salads or in place of part of the rice, is enough to make a difference.

Clinical Definition
Pulses contain 20 to 25 per cent protein by dry weight, 15 to 25 per cent dietary fibre, resistant starch and oligosaccharides, and have a low glycaemic index. Meta-analyses of randomised trials show that diets enriched with roughly 130 grams of pulses per day produce modest but statistically significant weight loss of about 0.3 to 0.5 kilograms over six weeks compared with control diets without deliberate energy restriction, alongside reductions in total and LDL cholesterol and improved glycaemic control. Postprandial satiety is increased through delayed gastric emptying, slower glucose absorption, short-chain fatty acid production from colonic fermentation, and stimulation of peptide YY and glucagon-like peptide 1. The main practical constraints are gastrointestinal: bloating and flatulence from oligosaccharides, which usually settle with gradual introduction, and phytate content, which reduces mineral absorption.
Key Insight
Why It Matters
For patients who need to eat less without feeling hungry, pulses are the cheapest lever available, and in a Singaporean diet dal, chickpeas and bean dishes slot straight into the existing cuisine.
