I agree with @Dr_C that 1200 is too low.
@Billkaulitz29 Here is the complicated explanation:
Your weight is 175 or 79.5 kilograms. To maintain 79.5 you need to eat
79.5 X 24 = 1908
not very active we multipy by .3 = 572
1908 X .1 = 191 for SDE
Add it all up 3052. Meaning you are probably eating around 3000 calories a day currently, and if you are gaining weight every week, it is going up and up.
If you want a goal of 140, and increases your exercise (I am assuming you don’t exercise/not active much now, I could be wrong) you need to consume 2267, less if you don’t increase your exercise. What his means is if you can figure out a “diet” that you are happy with that is around 2200 calories, you will eventually get down to 140 and will maintain it, instead of gaining the weight back like most do. You can cut more, will see more weight loss, but will have a hard time staying on the diet I think. The biggest problem in teh weight loss world is people lose weight, but the stop their diet and go right back to gaining weight, back to their old weight eventually.
My original suggestion was to cut around 3500–4000 a week and increase your exericise, if you remember, so that would be around 2400 calories. But, you will have to eventually cut down again to get down to 140, because 2400 calories a day does not equal a weight of 140, it is more.
Not sure if I explained it well.
What matters is figuring out what weight you should be for your height, or what weight you want to acheive, and then how to get to that weight. Each weight, almost regardless of how tall you are requires a certain amount of calories to acheive/maintain.
