Hungry means you crushed your workout!! Try to eat within one hour if possible. You want a nice protein-carb snack or meal (Greek yogurt with fruit, Turkey wrap, Tuna and whole-grain crackers, Protein shake with a banana). If you want to get super technical when it comes to exactly how many grams of carbs and protein to eat after your workout, here are some general guidelines I give my clients: 1 to 1.5 grams of carbs per kilogram (1 kg = 2.2 lbs) of bodyweight and 15-25 grams of protein. So a woman weighing 150 lbs would aim for 15-25 grams of protein and 68-102 grams of carbs. Hope this helps.
I would recommend a whey protein shake to quickly fuel your muscles. Include a healthy fat, such as 1/4 of an avocado, as well as a handful of spinach to add some greens. You can also add 1/4 cup of dry old fashioned oats, as a carbohydrate option. Once it's all blended together, this should satiate your hunger.
