Think protein shakes are just for beefcakes? Nope - more and more women are using them to fire up their regime. Why? "Protein is essential for the growth and repair of muscles," says Charlotte Kennedy, a sports nutritionist at Etixx. But our bodies can't store it, so we need to keep topping up. Will they bulk you up? Not unless you're "doing substantial exercise," adds Kennedy. And whatever you need, there's a shake for you.
The Big Green by RhianStephenson, nutritionist and CEO of Psycle London
250ml almond milk
1 scoop vanilla-flavoured plant-based protein (pea, rice or hemp)
1 frozen banana, chopped
½ handful blueberries
Juice of ½ lemon
1 handful spinach
½ tsp spirulina
WHY IT'S GOOD: Spirulina is protein-dense, high in Omega-3, iron and potassium, and can help lower cholesterol. The spinach is an excellent source of vitamin K and A (for strong bones), plus the lemon will dose you up on vitamin C and aid digestion.
WE SAY: From its cool-mint hue to its fresh flavour, this is a great breakfast shake to start the day.
