Also, wanting to confirm that if you don't want to shoot yourself in the metabolism, you'll be honest with your activity level.

And your level is mostly unneeded stress, probably a good part of the reason for having problems.

Your strength training is probably not as strong as it could be if daily, your cardio isn't as good as it could be either. Unless you mean nice walking.

First week eating 100 extra daily - no exercise except 30 min of walking daily.
Second week eating another 100 - only lifting 3 x week.
Third week with another 100 daily - lifting 3x week and 30 min walking on non-lifting days.
You should now feel the difference in being able to really lift well when you haven't run your body down with no rest or food.
Fourth week with another 100 daily, lifting 3 x week and 30 min cardio at max Aerobic HR zone, no higher.
If you don't feel as strong on the lifting, you just proved what happens with too much cardio.

At this point your calories should be correct for Moderately Active TDEE. May need another week of 100 more again.

i have been adviced by my trainer to do light strength training daily along with cardio since it will be able to strengthen the muscle and there will be an inch loss..........
how long should i be increasing my calorie.... since i am gaining weight after increasing my calorie.. at present i am on a 1500 calorie diet,, should i increase till 2300 which is my TDEE or stop when my weight stops gaining and reduce 15% calories... really confused

No, don't stop when you stop gaining (unless you have reached your calculated TDEE), cause then your body will take this lower number as your new TDEE, which you do not want.

It is normal to gain, and your body will need some time to be able to trust you again. You have been starving yourself over quite a long time, so what your body does now, is storing every morsel of food that comes in, in case the next famine is around the corner. Once you feed your body properly over a longer period of time, and when your metabolism has reset, you will cut slowly 10-15% of your TDEE.Only if you fuel your body properly, even when you are cutting, it will start to willingly let go.

Please be sure to either read all the stickies, or better get the starter kit. It is essential, that you know, what to expect. It can be mentally challenging to gain weight. If you are prepared for what's to come, you will be able to deal with it better.

If you increase your cals slowly or jump to TDEE is up to you. everybody dies it differently. I went from 1200 straight to my cut value. Since I was not losing I upped to my TDEE. I personally found it easier to jump straight in, but I guess it depends on you. However you feel more comfy with, go for it. It will take longer though if you increase slowly, as you are supposed to eat at TDEE for 6-8 weeks, some people need even longer to reset.

Best of luck

Light strength training may not even maintain the muscle.

You lost a lot on that diet, you need to maintain.

You should be increasing your calories 100 extra a day, each week adding another 100 daily, until you reach your TDEE.

But - you need a new TDEE. You need to cut back on activity, and make that which you do really count for something. The body responds best to hard stress, great rest and recovery. Constant stress daily is NOT good.

Don't be confused, and stop being stressed about it. Think back to how long you have been wasting time and muscle mass on previous diet already with no results.

Ready to change your thinking that several weeks isn't that long?

I spelled out your first several weeks, recalc your TDEE based on ending with 3 x weekly weight lifting, and 3 x weekly walking up to 60 min. That's going to be your new TDEE if you want to cut out your stress.
That would be the Moderately Active TDEE, rounded down to nearest 100.

If already eating 1500 then start doing what I spelled out there.

the most funniest part ever ......... is my trainer advicing me not to eat till my TDEE calorie but to have some food tht will boost ur metabolism like green tea, tulsi leaves, oregano . etc. and maontain my 1300 calorie diet ........ but my BMR is 1445... now i am confused as to wht to do reset my calorie intake to TDEE or eat 1300 calorie diet planned by her.........

So you know what the BMR is right. Calories your body would like to burn taking care of and supplying energy to all the cells.

You are giving it less than that. Since it is literally spending energy on all the cells, it is needing that taken in for the most part.

It's not even getting that. So it's slowing down because it doesn't have the energy taken in to use.

So it can't speed up, or it would never have dropped in the first place.

A trainer is NOT a dietitian, and even some of them haven't kept up with current knowledge/studies. Neither do they many times follow their clients long enough to see how their plans fail.

If you speed it up artificially, meaning anything causing it to go faster than it normally would, then your body will just make sure you burn less energy on other things to make sure enough is left over for your increased metabolism, you will have no daily NET gain in metabolism.

Several studies have found that when you go too low eating, your body just slows down other activities.

So you burn 500 calories in an hr workout. You would have burned 100 during that time anyway with normal activity.
Net calorie burn 400.
Now you are tired later in the evening and what was 2-4 hrs of more activity doing stuff has turned into longer sitting time, normally would have burned 600 calories, now only 300 calories, so just lost 300 extra calories.
Net calorie burn is 100.

Studies have shown this happening. This is how your body balances out.

So please, take your trainers advice since you have great success so far, and head on back in 6 - 9 months after having 2 - 4 months of no weight loss or measurement changes and your trainer is convinced you are doing something wrong. Oh wait, you've already had 6 month plateau!

If not, you've been given plenty of good advice above to help decide which one you are going to wrap your mind around.

Or do some self-education and decide which way sounds more sustainable, also based on your past experience if you've ever lost weight before.
