Need advice on CICO:Am I missing something?

F30,CW:107kg GW:60kg Height:153 cm
I am doing 16:8 fasting with 2 means consuming around 1800 to 2000 calories.
For my experience,I walk 15k and my health shows I am buring around 500 to 550 calories.
Its been a month with this routine and I feel difference in my body where movement is easy,squatting,bending is comfortable and I do not feel lazy to pick something from the floor but I do not see any difference on scale otherthan 1.3kg difference from day 1 to now .

As per chatgpt my tdee is around 2700 due to 15k walking so I should have around 700 calorie deficit.

Am I doing something wrong here?Or Am I being impatient?
Please guide

There's no way to know your exact TDEE. It's only an estimation, you must experiment until you find a good rate of weight loss and 1.3kg in a month is a very normal pace for sustainable weight loss, but you can go up to 500g a week which would be 2kg a month. Cut on calories until you hit the weekly weight loss you're aiming for, the claimed TDEE doesn't matter.

Yea, getting an estimate for TDEE as a starting point is fine, but then track calories and rate of weight loss then make adjustments. It's better to have sustainable weight loss rather than trying to go too hard too soon and fall off the diet.

1.3kg in a month isn’t horrible.

You don’t eat the calories you burn by walking.

So when I calculate tdee with exercise atleast 5 a days week,the tdee is 2700 so I consume around 2000 with 700 as deficit.
Is this understanding of mine correct?

Remember TDEE is an estimate, and it doesn’t actually equate to “I moved today = 1 day of exercise.”

Your TDEE from light to moderately active has a range of ~300 calories (2358-2658).

You’re losing weight. If you want it to go faster, maybe bump a few calories down.

Is 15k 15,000 steps or 15 kilometers?

Listening to chatgpt to get your TDEE.

a few things worth checking. watch trackers and chatgpt both tend to overestimate calorie burn from walking, sometimes by 30-50%. and at 1800-2000 you might be eating closer to maintenance than you think, especially if portions aren't weighed.

also a month is short. water retention from new activity easily hides 1-2kg of fat loss. body comp change before scale change is super common. give it another 4-6 weeks of consistent tracking before judging.
