According to many professional trainers and sports doctors, working out may not be enough to build muscle. When we eat and what we eat pre- and post-workout can impact how much muscle we build or don’t build. Some of the things recommended for exercise lasting 45-minutes or more are:
— Eat within one hour of exercising, both pre- and post-workout
— Eat proteins and some carbohydrates that digest quickly in order for the muscle-building nutrients to reach your muscles quickly. Muscles are made of proteins and amino acids which start to break down during intensive workouts so if you do not do this, your body may draw on existing muscle to replenish itself after exercise. 
The smoothie recipe below includes whole foods that can help build muscle. Just throw everything into a blender and blend on high speed for 30 seconds.
- Quickly absorbed proteins: Yogurt and Milk (1½ cups total combined) Not only does this contain the essential proteins touted by all as essential muscle-builders, but the good bacteria in the yogurt will help quickly breakdown all of the goodness in your smoothie. The yogurt to milk ratio depends on how thick the yogurt is because if the yogurt is very thick, the smoothie can start to taste like banana bread batter. If your yogurt does not contain pectin, use 1 cup cow yogurt and ½ c. cow milk. Cow milk contains the most amount of protein of the milk options. In addition, I could not find non-dairy cultured products that contain sufficient protein except for cultured soy but I cannot in good conscious recommend these soy products because of their effect on hormones. (Stay tuned for that blog…) If you are lactose-sensitive and/or trying to reduce your carbon-footprint, you might try cultured goat milk with almond milk. There is one in the New York City-area from Coach Farm that is delicious in this smoothie when combined with Pacific Food’s Organic Unsweetened Vanilla Almond Milk. The cultured goat milk is thin though so add an extra ½ banana if you go that route.
- Quickly absorbed carbohydrate: Banana (2 medium-sized bananas) Glycogen is derived from glucose, a sugar molecule, and it is the primary fuel for exercise. It depletes as you work out and is one of the primary things you want to consume in order to restore your energy. Bananas are an excellent source of easily accessed glycogen for your body according to personal trainer and exercise writer, Mike Samuels.  While loaded with nutrients, the fiber in whole grains can take a while to breakdown and can slow down the breakdown of proteins. Bananas however are a good source of carbohydrate post-workout because they provide the needed sugars of a carbohydrate without a lot of complex fibers. Bananas are also an optimal carb because they contain potassium which is said to support heart health. Some believe bananas prevent muscle cramping as well. 
- Vitamin B6: Pistachios (1 tablespoon) Vitamin B6 helps break down proteins and carbohydrates and help get these things to your muscles quickly. It is also said to reduce inflammation in addition to supporting the nervous system which is activated during workouts. 
- Anti-inflammatory: Turmeric powder (1 tsp.) This powerful powder typically used in curry blends is derived from a root similar to ginger. It has long been used for its inflammatory properties and a 2009 study showed that turmeric’s pain-relieving effects comparable to ibuprofen.  Part of what enables turmeric to work its magic is that it thins the blood. This may be of concern for some people who have blood-clotting issues or who have recently had surgery or will have surgery. Turmeric is also contra-indicated for gallstones. If this is you, check with your doctor about regular turmeric consumption.
- Electrolytes: Salt (a small pinch) As is commonly known, you lose essential salts through your sweat so adding a pinch of salt will not only replenish your eletrolytes but it will also make you subtly thirsty for more fluids. 
 There seem to be much debate about the precise window within which one should eat as well as the precise ratio of proteins to carbs but it seems clear that eating within one hour cannot hurt and waiting may hurt.
