I lost 130 lbs so i know how you feel.
seems impossible but its actually pretty simple.
1- This weigh yourself the first day. now eat exactly like you do now, nothing different. the only thing different is that you need to write down everything you eat. everything. write down the time you ate it too and how much.
2- next week. do the same thing but this time try to eat the same stuff but now split it up into 6 meals per day. So instead of skipping breakfast and eating a giant lunch, eat that same food but onky eat like half for breakfast and the second half for lunch. Make sure you are aiming at about every 3 hours. Absolute worst case, you are still hungry and will eta again in 3 hours. not too hard to do that. write down everything you eat again.
3- Week 3. now start looking at those same meals figuring if you can trim the sizes of them some, maybe 1 slice of toast or no cheese, something simple like that. of course write it all down.
4- week 4. now you have been doing this for 3 weeks so you know you wont starve to death and you dont have to eat celery all day so start taking a closer look at those calories that you are really ingesting. Just by doing this and shopping smarter you can trim a huge amount and not feel like you are starving to death.
5- Now start dealing in the diet, calorie wise every meal. shoot for a target calorie intake every day and make sure you hit it. trying to outsmart it and not eat wont work so some days you will have to eat even when you arent hungry to keep the machine working properly. I would personally shoot for about 2500 cals per day as a starting point. everyone is different. the key is, if you eat that much per day all week and lose1-2 lbs, then its working so stick with it until you stop losing.
The trick is to write down everything and to be honest when you do it. you are only lying to yourself. Also, forget salad and veggies and all that jazz. i didnt and still dont eat any of them and lost weight just fine.
After this its just a matter of repeating this every day until you hit your goal.
you are going to be eating every day anyway so might as well lose some weight in the process.
