What is a negative net intake of calories?

Is a negative net calorie intake a good thing, bad thing, or it depends?

Today I have been working on the house constantly. I recorded it as 'Housecleaning , light" because i could not find an equivalent. MFP calculated an overall negative calories.

(This may change. The family wants to eat at cracker Barrel tonight. I think they even serve their salads with Sawmill Gravy.)

Having low or negative calories is not a good thing, no.

It's like expecting a car to drive on an empty tank. Your body requires a base amount of calories just to sustain basic life functions. Take that away, and where does that leave you??


As for MFP's database, I'd eat back 50% of those calories, since MFP is notorious for overestimation.

Go to Cracker Barrel, have something yummy, enjoy your time out and just remember to log it. /end

Oh, you know my spouse? The "E" on the gas gauge is a suggestion, not a statement.

Okay, to be more specific... will one day of negative calories hurt you? Probably not. But if continued for an extended amount of time, yes, you will begin to experience negative effects.

Here's a good thread with some studies linked (scroll down a few comments for the info):
