Week 3 is coming to a close with more changes coming in week 4.
Remain consistent and close out this week strong. As with any long term goal the key is consistent action and hanging in there when you don't want to.
Remember it's important to intake adequate protein for recovery and supporting muscle mass.
In a caloric deficit going long periods without eating will burn muscle mass that you worked so hard to gain.
Try to space your meals every 3-4 hours
