What is a high-protein diet?
A high-protein diet is one in which you get a significant portion of your daily calories from protein-rich foods, such as eggs, beans, meat, dairy, fish and tofu.3
High-protein diets typically mean getting a higher percentage of your total daily calories from protein sources than dietary guidelines usually advise. The guidelines generally recommend around 0.8–1g of protein per kg of body weight per day.4,5 For example, a 60kg adult would need 48–60g of protein per day.6
Because protein supports muscle growth and repair,1,2 high-protein diets are often popular and recommended among athletes.4 They may be suggested for other reasons too; for example, older people are recommended to eat between 1–1.5g of protein per kg of body weight to help support their ability to fight infection and promote wound healing.2
There’s a bit of a discussion around how much protein athletes need in their diets. Previously, it was thought that they didn’t need more than the standard guidelines. However, research now suggests that athletes might benefit from eating 1.4 to 1.8kg of protein per body weight per day.4
If you want to follow a high-protein diet, you would need to eat more than your recommended daily amount but make sure to consult with a medical professional or dietician first.
Some well-known high-protein diets include:
- Atkins diet
- Stillman diet
- paleo diet
- zone diet
- Dukan diet
- ketogenic diet
However, you don’t have to stick to a specific diet plan to increase your protein consumption.
