I don't lose weight at 1200 cal, so I try 1100, never below 1000.
Everyone is slightly different. The more you have to lose, the more calories you're using to maintain your weight so start with a hight daily amount.
My tip is, be patient. Don't try to go from eating whatever you want to a struct daily total. Instead, allow yoursrlf time to adjust. I suggest taking a week or two just to conciously cut down only a comfortable amount. Start making healthier choices, but don't calorie count.
Then, stage 2. Continue to try to cut down a little more, and begin to count calories. Don't aim yet for a speific total, rather, count what you're eating to get an idea what you're actually consuming.
Stage 3. Now start counting calories. Write down everything. Just a list add ip as uou go through the day. Don't get discourage dif you go over a little. If you get to the stage where you're utterly miserable and ready to gnaw at a table leg, eat something. A slice of toast, an apple, a couple of rice cakes. Just
something. Stay sane!
How to count calories easily and accurately- don't guess, use scales.
I have a list, a column for fruit, for veg, for protein, for treats. Each food item has the number of calories next to it. Examples Grapes, 20 cal per 30g.
Apple 40 in 89
0g, so half the wright in grsms = the calories. Soon you know what there is in your portion without looking it up.
Don't divide your daily calories into 3 ewual meals. Make at least 2 meals smaller, then you have spare calories for a couple or three snacks.
Finslly weighing.
Only weight once a week. Weigh at the same time, dressed or preferably undressed. Go to the loo first. DH & I weigh after bathroom, before breakfast.
Then write it down on your date/ weight list.
This approach really works. DH has lost a stone so far, I've lost 10 lbs. DH often loses 2lbs I often only lose half or 1 lb. Doesn't matter, it's going in the right direction!
It's perfectly normal to have a week or two when you lose very little or no weight. Sometimes even, your weight might go up. Of you have honedtly kept to, or very close to your target calories, it may just be you've retained more fluid that day.
Good luck!
