Vlog time! I hope this video helps a little with any confusion you may have around calorie counting, portion sizes, and macros. I also (attempted) to show you how to set yourself up on myfitnesspal.com but I couldn't get my camera to flip over, so it may be a little hard to see.
Click here ( scroll down about 1/3 of the page) for the link to figure out how many calories is right for you. You'll want to follow the "lighter day" recommendation on off days and days you work out smaller muscle groups like arms and shoulders. Then on heavier days you will bump up your calories a bit. This is called eating for your activity levels and I have found it works wonders. If you fuel your body properly when it needs it, it will trust that it will be fed and let go of that unwanted fat! As always, let me know if you have questions!
