Weight loss tick for Paleo diet

The Palaeolithic, or paleo, diet has been found to be more effective for weight loss than the Australian Dietary Guidelines

Researchers from Edith Cowan University have found the Palaeolithic, or paleo, diet more effective for weight loss than the Australian Dietary Guidelines.

The study by ECU’s School of Medical and Health Science involved 39 healthy women, with half eating a paleo diet while the rest were assigned the Australian Guide to Healthy Eating (AGHE) diet over a four week period.

The paleo group lost an average of 2kg more over the period than the AGHE diet group.

Lead researcher Angela Genoni said the study also examined the impact on cardiovascular health and found no significant difference between the paleo and AGHE diets.

“While both groups lost weight over the period, the paleo group lost an average of 4.3% of their body weight over the testing period, compared to 1.6% for the AGHE group,” she said.

“Despite the greater weight loss, we should be cautious about advocating a diet that cuts out entire food groups.

“Significantly, the paleo diet markedly reduces the calcium intake relative to the AGHE diet because it excludes all dairy products, which could have a negative impact on bone strength, particularly in older people.”

Study participants sought

Associate Professor Amanda Devine, who also contributed to the research, said that more research was needed to fully understand the health implications of the paleo diet.

“There is much more to health than simply weight, so dietary patterns that exclude entire food groups are likely to impact overall health due to a reduction in food variety therefore further research is required in healthy subjects to assess the long term health impacts.”

Professor Devine said a further study was planned that would particularly focus on the impact of the paleo diet on gut health.
