Need some clarification

this helped me to see the light.

I'm at the higher end of my health weight range (currently 70kg) and I'm looking to lower my body fat by about a 1 kg per week. My job is sedentary, but I'm very active outside of work. This week I burned nearly 6000 calories through exercise and that's only going to increase over the next few weeks. My net daily calories is consistently less than 1200, sometime way, way, way less. I'd lose body fat faster if I consume most, if not all, of my exercise calories, correct?

In theory yes.
MFP calculates our total daily calorie intake WITHOUT exercise to lose 1 pound or so per week.
And after we log exercises, our daily calorie limit increases.
Why?
Because MFP telling us to eat our exercise calories.
Large deficits are unhealthy, because while you will lose weight, what's the quality of the weight loss?
In many cases you'll lose lean body mass - MUSCLE - which LOWERS your metabolic rate, making weight loss harder.
These crash diets work well for a season -- and sure enough, the pounds melt away. But when you eat so
few calories, you train your metabolism to slow down. Once the diet is over, you have a body that burns calories
more slowly -- and you gain weight.
Be smart.
Exercise well both cardio and resistance, and eat back the calories.
The exercise will RAISE your metabolism and burn more fat at rest.
