If you're looking to lose fat or build muscle (or both - it's possible to achieve both simultaneously), keeping your protein intake up is really important.
Losing fat comes down to being in a calorie deficit (taking in less energy than you're expending), and eating enough protein helps your body hold on to muscle in the process, which is something I found when I cut my body fat percentage in half.

Protein is also great for keeping you full as it's so satiating, and it's important for helping your muscles repair after a workout.
Over the past couple of years, I've lost a little more fat and built muscle, a journey that's been helped by keeping my protein intake high.
"The majority of people in the western world eat a sufficient amount of protein on a daily basis (i.e. at least 0.8g per kg of body weight a day), however, some people do struggle to consume adequate amounts, particularly if they are exceptionally active or follow a plant-based or vegan diet," registered dietitian Nichola Ludlam-Raine told Insider.
If you're into your fitness, experts generally recommend consuming 1.6-2.2g of protein per kg of bodyweight per day.
While in an ideal world we'd all get sufficient protein from whole foods, I personally find this tricky at breakfast, so sometimes add protein powder to my first meal of the day.
Here are seven of my go-to high protein breakfasts, approved by Ludlam-Raine - whether you lose or gain weight comes down to your overall energy intake over the course of the day, so vary portion size to suit your lifestyle, body, and goals.
