If you’ve been following my Metabolic Fat-loss Program (or even if you haven’t), you’ll know how often I mention protein sources – foods being high protein or foods having a good protein / carb balance.

What I’m probably a bit rubbish at talking about is why! Why is it important to eat more protein? How does it affect your health and weight loss? How do I eat more?

Protein is important because it helps you feel fuller longer. Having protein around slows down digestion making you more satisfied. If this happens over the course of multiple days, calorie savings can help with weight loss.

A high protein diet has a number of health benefits. It works to stabilise blood sugar levels, improve the ability to learn and concentrate, reduce brain fog and boost energy levels.

It’s a scientific fact that the body cannot effectively burn and use fat as energy if it doesn’t have help from either carbohydrate or protein. Having adequate protein coming in from food, fuels fat burning while preserving calorie-burning lean muscle.

7 healthy (and cheap) protein sources

1. Natural Peanut Butter
Peanut butter is full of protein. A two tablespoon serving provides 8 grams of protein. Aside from being a great source of protein, peanut butter can be used in many ways. Pair it with fruit and oats or add it to your favorite smoothie for a protein boost.

2. Eggs
Eggs are one of the most nutrient-dense foods on the planet. Not only are they full of vitamins, minerals and healthy fats, but they are also packed with protein. One large egg contains 6 grams.

3. Edamame
This tasty, bright green bean is an amazing, low-priced source of plant-based protein. Edamame beans are immature soybeans that are sold both shelled or in the pod. They are a delicious snack and make a great addition to meals like salads and stir-frys.

4. Black Beans
Black beans are one of the most convenient and affordable forms of plant-based protein that you can buy. One serving of black beans (150g / 5oz) contains over 15 grams of protein.

5. Sunflower Seeds
Although sunflower seeds are tiny, they contain an impressive amount of protein. Just one ounce contains about 6 grams of plant-based, vegan-friendly protein. These nutritional powerhouses are packed with protein, as well as nutrients like vitamin E and magnesium.

6. Lentils
Not only are lentils a highly nutritious and affordable food, but they are also a great source of protein. These tiny legumes can be cooked and added to a variety of recipes like soups, stews and curries.

7. Oats
Oats are a hearty, gluten-free grain that is very inexpensive. They also happen to be much higher in protein than other grains. A 40g serving provides 7 grams of protein.
