Question about Keto!

D • 20

So I got the Keto app and I’m not a big eater, it set my calorie intake to close to 2000 I think?? Not exactly sure but I take in about 1000 a day so if I do the diet but only eat the 1000 a day will I still lose?

I weigh 154 and want to get to around 140-147 so it’s not a huge goal I already drink loads of water too
