It's a hot trend, but what do the health experts say?

The Paleo diet is a hot diet trend that advocates eating like humans did in the Palaeolithic era, claiming that our genetics are mismatched with our modern diet. Also called the caveman or Stone Age diet, Paleo emphasises lean meats and plant foods while eliminating grains, dairy products and legumes. It claims to not only induce weight loss but also help control glucose levels, blood pressure and cholesterol.

So is the Paleo diet all it’s cracked up to be? At nib, we’re not just your insurer, we’re your health partner and we work with the experts to get the tips and programs to help you live healthier than ever. So, we spoke with Bayley Houston, accredited practising Dietitian and Allied Health Coach at Honeysuckle Health to find out everything you need to know about eating Paleo-style.

Does Paleo help with weight loss?

“There have been some small studies that support the claims about weight loss, but currently there is no strong evidence to back these claims or about the long-term effects of the Paleo diet,” says Bayley. “We currently can’t make any scientifically backed claims about its benefits.”

While you may initially lose weight on the Paleo diet, its restrictive nature can make it hard to follow in the long term. “The evidence suggests that most of the weight loss from dieting is regained following the completion of the diet,” says Bayley.

A typical day’s Paleo meal plan

“The Paleo diet encourages the consumption of lean meats, oily fish, non-starchy vegetables, fruits, seeds and nuts,” says Bayley. “Yet it restricts the intake of core foods like grains, legumes and dairy which play an important role in bodily functions, muscle and bone strength, bowel health, blood cholesterol control and glycaemic control.”

Some variations of the Paleo diet include a small amount of gluten-free grains such as rice and oats, but Bayley doesn’t believe these versions are any more nutritionally sound. “There has been no evidence to suggest a gluten-free diet improves health in people who aren’t coeliac or gluten intolerant,” he says.

“There also isn’t any evidence that including a small serving of grains improves health more than meeting the recommendation of five servings of grain foods per day.”

A typical day on the Paleo diet might look like this:

Breakfast: Almond-milk smoothie with avocado, kale, banana and apple

Lunch: Fried fish fillet with mixed salad leaves, pumpkin seeds and an olive oil dressing

Dinner: Roast chicken with a stuffing of carrots, onions and rosemary

Paleo food list

Not quite sure what the Paleo diet entails? Here’s a list of foods it includes and a list of foods that it suggests you avoid (although remember to chat to your health professional before trying a diet like this to give you personalised advice).

Foods to eat on the Paleo diet

  • Lean meats (especially grass-fed meats)

  • Fish and seafood

  • Fresh fruit

  • Fresh vegetables

  • Eggs

  • Nuts and seeds

  • Healthy oils (olive, avocado, and canola)

Foods to avoid on the Paleo diet

  • Grain (cereal) foods (wheat, oats, rice, rye, barley, millet, quinoa and corn)

  • Legumes (including peanuts)

  • Dairy products

  • Potatoes

  • Refined sugar

  • Processed foods

  • Overly salty foods

  • Refined vegetable oils

The bottom line

While Bayley doesn’t believe there is enough evidence to support the Paleo diet, he recommends seeking the help of a professional if you want to try it. “As a dietitian, I'm against recommending restrictive diets unless there is strong evidence behind their therapeutic effects,” he says. “But if you still want to follow a Paleo diet, seeing an accredited practising dietitian for assistance is the safest way to do so.”
