"You need 2500 to maintain"
No I don't - this is a guideline for men who actually do something? I just tell people off on the internet for 8 hours a day :)
"maybe 1500 to 2000 to lose weight ?"
I probably need something like 1800 to maintain.
"You'd be starving yourself in 900. I'd do nothing but think of food and wonder why I was doing this to myself on 900 a day."
That's where the willpower comes in! It's porridge for breakfast, soup for lunch and a massive salad for dinner. I don't feel starved now that I know what actually being hungry feels like.
Have a go at this and see what you come out with:

This doesn't ask about activity levels and puts me at about 1916 cal.
This one gives something closer to your estimate:

Thing is, I simply don't believe them - or the labels - or my counting - so it's better to be a bit harsher with myself.
There's nothing wrong with being a bit hungry :)
My BMI is is now 23.2, which means I am almost safe. I would like to take a little more off to improve my cycling performance up hills though.
"I'm still using the old WW system I succeeded with many decades ago. It works out as either 2142 calories and no saturated fat a day or 0 calories and 120 grams of saturated fat a day (?!?) or a practical combination in between :-) The reality is though that I am rarely under, usually a bit over, and a lot over at weekends. Thus no real progress since I dropped down into the 'overweight' category."
Maybe you need to update? :)
I've cut out fat almost entirely as well as most carbs and meat. To be honest, I feel so much better for it. Much less "processing" I feel!
