Paleo + vegan diet = the Pegan food plan
The Paleo diet could be phased out thanks to a new regime that combines the so-called caveman diet with a vegan lifestyle.
When people go Paleo, they vow to eat only things our ancestors could have got their hands on. That means anything processed (bread, sauces, chocolate) is out, but meat, fish, eggs, vegetables and fruit are all on the menu.
Meanwhile vegans rule out any animal products, so no meat or dairy, and load up on grains, fruits, nuts, seeds and vegetables instead.
Now Dr Mark Hyman of the Cleveland Medical Centre in the US has come up with the Pegan way of life, which incorporates both of these diets.
"A Pegan diet mixes the principles of Paleo while incorporating more fibre and grains, adding to a more fibre-rich diet overall," Sydney-based dietician Susie Burrell told Daily Mail Australia.
The great thing about Pegan is that it combines all the food groups you need, such as protein, grains and good fats. However, it avoids diet baddies like dairy and sugar.
Pegan also monitors meat intake, which is very different to the Paleo approach, where followers can pretty much eat as much as they like. Meat has been linked to health problems, including cancer, and limiting your intake can help control your weight.
One thing you need to watch out for is your calcium consumption. As vegan rules out any animal products, it can mean followers struggle to get enough calcium, which you'd normally take in through milk and cheese.
Need some inspiration for your first day on Paleo? Why not start off with a healthy breakfast of scrambled egg with avocado, then tuck into a chicken salad with at least five types of vegetable at lunch. Snack on fruit and nuts, then finish with a healthy dinner of fresh fish, quinoa and green beans.
