Study confirms dietary advice to aid weight loss

Purdue University

People who are attempting to lose weight in preparation for obesity treatment might be interested to learn that eating three square meals a day will help them feel fuller while they lose weight.


Conducted by a team from Purdue University, the research confirmed that eating fewer, regular-sized meals with higher amounts of lean protein, will help people to feel fuller than if they were to eat smaller meals more frequently.


Published in the journal Obesity, the research looked at 27 overweight and obese men, who were divided into a high-protein group and a normal-protein group.


They were all given a calorie constricted diet for 12 weeks, but the normal-protein group derived 14 per cent of their energy from protein, 60 per cent form carbohydrates and 26 per cent from fat.


Meanwhile, the high-protein group received the same amount of fat but 25 per cent of their energy from protein and 49 per cent from carbohydrates.


Assistant professor of nutrition and exercise physiology Heather Leidy worked on the study.


She commented: "Although we found that daily hunger, desire to eat and preoccupation with thoughts of food were not different between the normal- verses higher-protein groups, the higher-protein group experienced greater fullness through the day."


Professor Leidy added that the men who were eating higher amounts of protein while trying to lose weight eventually also experienced a reduction in late-night desire to eat and had fewer thoughts of food.
