Question About MFP

I like to. For example when I drink tea, I add 1 cup of water to my H20 log and then add the tea type (which is usually 0-5 calories) to my food log.

Its good to track drinks even if all you drink is water. Its good to know that you are hydrating properly.

Because MFP is set up to tell you how many calories you need to lose weight without exercise. When you then exercise and burn more calories, your deficit (the difference between what you eat and what you burn) gets bigger, so you're supposed to eat some of those calories back otherwise your deficit will be too aggressive (leading to hunger, lack of energy, too-fast loss, muscle loss etc). It does over estimate though, so general consensus is only to healf half of those back.

I log the drinks that have calories, it can definitely add up pretty quickly if you drink juice, milk or soft drinks like sweetened tea. Beer has tons of calories too! You could be going way over your goal without even knowing it. For me, MFP only works if I log every single thing!
