This is a question we get A LOT! And it's an answer we don't have until we have a lot more information from you!
What's working? What's not working? What are your goals? How's your energy? What's your lifestyle like? Work schedule? Workout regimen?
Not to mention.... your height, weight, age, gender, health history, medications.......
Regardless of the above answers, you have to know where you are starting in order to get where you want to go so take a self audit. Track your intake without any changes for a full week. Start with calories. Add them all up and divide by 7. That's your average daily intake. From there, make small, sustainable adjustments to start the process towards your goal(s)!
