TDEE Question....

I could really use some help as well. I'm 5'5 and 205lbs. I'm a stay at home mom with a 12 year old, a 9 year old and a 10 month old. I am currently keeping my calories under 1000 a day and doing cleaning everyday, and light exercise 3-4 times a week for 30-40 minutes and I haven't lost any weight yet. I don't know what I'm not doing or doing wrong. Can someone please help me?

It sounds like you are eating too little.You need to figure our your BMR, there are calculators online, you can goolge BRM calculator.
The BMR shows how much you need to eat to keep your organs and body functioning. It is the very lowest level needed and doesn't take into account daily habits such as cleaning, walking, etc. For a 35 year old woman, her BMR is about 1600 calories. I personally wouldn't eat that few of calories, only because I don't think I could sustain the hunger. So I eat at my BMR of about 1600 calories. And all of the exercise and walking and cooking and cleaning counts as extra calories burned. You TDEE shows the number of calories you burn per day, it takes into account your BMR and your daily activities. You can find a TDEE calculator online. MY TDEE is 2200. That's how much I burn a day, so if I only eat 1600, I should see weight loss that is steady.
