By adding whey protein powder to your coffee, you’re able to get upwards of 20 grams of protein in the time it takes to boil water. For those working on building muscle, starting your morning with protein will put an end to your body’s overnight fast, restocking glycogen stores, and subsequently stopping muscle breakdown. But mixing protein powder with coffee isn’t just for athletes. Protein – especially in the morning – can also help support fat loss, increase energy levels and help with concentration.
