When does protein become too much protein?

High protein diets have long been considered one of the most effective ways to lose excess weight. However, new research suggests too much could be harmful to your liver, while not enough can leave your body without essential nutrients.

When it comes to how much protein we should consume there's no 'one size fits all' approach. Pensioners for example, don't need the same amount of protein in their diet as a teenager, while many people aged over 51 don't get enough in their daily diets.

A general rule of thumb is to eat 0.8 grams of protein per kilogram of weight. If you're more active, playing sports or going to the gym, then feel free to add a little more.

Protein is essential to the body's healthy functioning, including cell recovery and muscle composition. If you're a vegetarian then eggs, hummus and nuts are suitable replacements for meats.
