Considering the financial troubles, what I have to offer may be what you are looking for. I could tell the whole journey, but, that is likely for a better time.
From overly complex, I have just tried to keep things on the simple end, though, the results are not simple, and fine tuning these habits has taken me many crashes, and many attempts to get everything in place as it must, and make it flexible enough to where I can make it succeed with a variety of resources, including time.
Diet
Mode: day A day B, every 7th to 8th day, take a break to get things like dairy, extra protein in you and things generally to raise proteins and fats. Not recommended to eat crazy stuff like cookies, cake, and the like, as this is waste of calories, considering we have a goal(s) we are trying to attain here.
Day A
1/2 cabbage green or purple, purple is better in my opinion, fresh
2-4 apples
Water throughout the day, bubbly diet sodas, teas, and coffees are good too. I generally limit myself to 1 coffee with creamer, or a tea with an artificial sweetner and creamer to make something of a one off milk tea
I hold off on water an hour or some more before beginning meditations and yoga, among other exercises.
I generally always eat in a 30 minute to 1hr window sometime after I get dressed and that is generally it for the day.
If at all you're feeling faint, I would recommend eating more and drinking more water, and as I have noticed in myself, eventually the body, mind, and likely soul as well adjust from the "needing a fix" feeling that you are trying to overcome. I have been there, and the less excuses you make, the better. Understand, in the case of weight loss, less is more, but you have to do it right so you aren't killing yourself instead of actually just losing weight and building your physique like you want to. I am still doing full physical workouts every single day, and only skip days if I am absolutely exhausted as soon as I am off work, unfortunately lots of stuff can get skipped on those days, but I try to eat a little more to atleast eek out a half rep workout session.
Note you see 3 of Day A and 3 of Day B, if you feel comfortable stretching this sequence before your more relaxed eating day, be my guest, but be very careful. I do notice a mood shift nearing and especially if I pass the 7th/8th day, especially if you have it designated and you are expecting it. Good food is good haha, but again, less is more counts here, and the goal here is to lose weight first, then gain muscle after your body has transformed in the direction of weight loss, if of course, that is truly what you wish.
Day B
1/2 Cabbage
2-4 apples (adjust amounts to what works for you ultimately) But I have accomplished alot in the less is more environment surrounding a goal that is all about losing weight, not gaining it.
800-1000 calories of protein, be it some kind of roasted meat as a good example. Not from dairy, or anything else. If all you have is protein bars, well, I have been there too, and I hope the best for you if that is how you accomplish that. The roasted meat, like a store bought rotisserie chicken portioned out to that calorie serving is a better specific example, though again, could be deli meat, try to not push the fats too hard, they aren't bad, but, less is more here when you are trying to lose weight.
Again, eaten all at the same time, drinks throughout the day to keep hydrated. I have run it down to around 500 calories of protein a day, but, I bumped it up.
7th/8th Relief Day
I eat a lot of meat, sometimes a sandwich, though fried chicken is cheap enough and generally hits the spot with bbq sauce, I mix up the calories and I generally eat till I am full. I allow dairy on these days, maybe even a protein bar if I want to torture myself. Protein shakes are good sometimes, but any of those bars/protein powders are still a trip to the indigestion zone, and atleast on my end, cause me a lot of grief, I would rather just drink a cup or two of whole milk, and be totally fine. I still eat the apples and cabbage. Again, I try to eat this all at once, then, generally nothing for the rest of the day besides keeping hydrated, as I will still be doing Yoga, Meditation, and other exercises that require a generally not full stomach.
Then reset to Day A, and repeat. It is hard at first, and learning to say no to others when they offer you food you should not be eating can be difficult, but you eat every day, and I would say the cabbage and apples fill you up well, whole packs of celery are good too. If I have celery, i eat a whole pack(bundle of stalks) per day.
So, no I do not eat the cabbage and celery by itself. Generally I dip it in a bunch of ceasar dressing and balsamic vinaigrette, I mix cayenne hot sauce into the ceasar at times too and I really love it. Other sauces I would permit as well, but those 2 are my choices.
That is what it is, and with my workout I will mention, you should be able to take that and the diet, along with some good resolve if you truly want to accomplish the goal(s), and be able transform your body to where later down the road you can focus more on tuning your muscles and physique after the fat is burned off.
The workout.
I have done alot before developing this workout, I believe the Gods had eventually lead me to the diet and the workout routine after I had struggled in a good way to get set up on both with regularity that allow me to do the workouts to completion while still allowing me to accomplish my Spiritual Goals to include but not limited to Yoga(s) and Meditation.
From start to finish and adjust your reps to what you can handle, AND what you can do every day. Since the weightloss set up allows for it to eventually be moved to the background so you do have time to do Spiritual advancement, you need to focus on what you can do readily and complete without too much struggle, every day. You can mix things up as well, but I try to train everything, every day, and for me it has been working quite nicely.
I do ONE set of each, and the reps, I keep around 15 for some, and others near 30, the weight and reps may differ for anyone using this, so do not use my rep as some golden standard, because it is not. Like I said, weight and reps can be adjusted, and everything should be easy enough to complete the whole track of workouts once, every day. Difficulty can be increased gradually over time.
Legs
Bodyweight squat jumping
Bodyweight squats
Bodyweight lunges
Core
Hanging leg lifts, v raises, or knee tucks. Eventually the V raises will come if you cannot do them immediately. The Hanging Knee tucks are an excellent way into eventually getting to the lifts/raises, V raises, and other workouts of higher difficulty.
Leg raises on your back
Knee tucks on your back
If you do not have a place to do hanging exercises, raise the reps on the leg raises and knee tucks after you get comfortable with them.
Shoulders
dumbell overhead press
dumbell side flys
dumbell front flys
barbell upright row ( I keep my hands centered more in the middle)
If you can do handstands in your house, I would do these. Eventually you can train for handstand pushups, which I would recommend over the dumbell work, but likely if I had the choice I would add the handstand work to the dumbell work. Crow stands keep you closer to the ground but still allow for training the wrists, shoulders, and balance.
dumbell shoulder shrugs, I use heavier weight for these, but when I use lighter, I shrug up and down with a certain rotation, like moving the shoulder back then up, forward, then down, or in the reverse of that
Lats/Back
Bent over row, I use heavier weight for this, make sure the back is straight and you have your other arm somewhere planted for good support.
Pullups if you have a place to do them, I will always recommend pullups and chinups, play with the grip and notice how it effects how the muscles engage, eventually one handed pullups can be attained. Losing weight helps get to this as well and gives a new starting point to accomplish new things with the lower weight.
Biceps
dumbell hammer curl
standard dumbell curl
barbell bicep curl
Pullups and row exercise also work these
Triceps
bent over dumbell tricep extension
overhead dumbell tricep extension
overhead barbell skull crusher (my favorite), but prefer doing them laying on a bench, current situation does not allow.
overhead barbell press
Chest
Pushups, for me, is all I do, considering my situation
But if you have a bench you can do some great workouts like pec flys
dumbell chest press
bench press
and so on, one day again hopefully for me but I'm making this work
I do ONE set of each of these, and you can see some overlapping areas as well. If anything, especially if you have a small leg problem you are trying to overcome, double up on the leg workouts, and settle with that. Unweighted squat jumping has done some incredible things to my legs over time, though later I may try to tackle this with a weighted vest. Ultimately, you want to be able to do these every day, I accomplish this in about a 30 minute period of time minimum, maybe an hour maximum, without rushing, but generally, constantly moving, but with stability, and an efficiency i have gained with experience.
If anything, try it one by one, workouts that is, and first see how your body reacts, and lift weight that you are not only comfortable with, but is easily manageable. You can always work up later after discovering yourself better. Be very patient, because even with light weights there will still be results. Don't worry about building muscle, as it will probably happen as you lose the weight, and you can get your body fat as low as you are comfortable with, before figuring out a way to integrate more good calories into this same diet for muscle growth if that is your goal later. But that is immaterial here, where the focus is weight LOSS, rather than gaining.
Don't step on the scale, just get away from it. Stay away from the mirror too. Focus on just doing. Getting the tasks done. Building the energy. Getting the habits in place. You aren't lying to yourself by staying away from these, just switching your focus to what matters more, especially when starting out. Check yourself out and flex on yourself more later when you have actually attained good results.
Modify this to your comfort, but as far as it goes, this is what i do personally, and it has worked wonders. Everyone is different, and my body and experience may differ from others here or there, but I can tell you, with confidence, that this works.
Some days are harder than others. Some days you may not have the energy to pull through. These days, i eat a bit more and I reduce ALL of the reps on my workouts by HALF. If a day is so crazy I lay on my bed and I almost immediately fall to sleep, I just do that. There will be the next day, and I am still on the diet, so it will help you to continue to lose weight anyways, even if you have some necessary rest days for workouts. This I have noticed, with the Spiritual side of things, even research on the ToZ, if you are already in the habit of doing these things constantly, advancing constantly, the days missed are far and few in between the actual days you're actually hitting, and truly making real progress, even if it just baby steps at times. It is not a goal to miss days, but life happens, be reasonable with yourself.
I do not mean for this to feel overwhelming, but, it is what it is, and if I wrote about how I got to this point, well, we would be here for a long time because it has taken a lot of fighting to find a good way to tackle this.
I have been fat before. A few times now

lol, but every time i come back to strike at dieting and continuing to hammer forward in my progress, ultimately towards the Godhead, I make it a bit farther, and now I have finally developed into the dietary plan I have created, evolving it into a lifestyle, and enjoying the fruits of my labors (which continue! they don't end just because you reached your goal, thats another part of what makes life so great, theres always something to work on, some how, some where, etc). I am happier living this way, rather than eating pizza and other stuff for months and then feeling like shit about myself after, it began to be that, when I ate the pizza, I started to feel that way before i was even finished with it, since I knew eventually what would become of myself. Its more worth it to make the better choices for the right reasons and not be feeling shitty about ourselves in some endless cycle. We have to get up and do something about it, and cheers to you if thats what you really want to do. There is a lot of tasty food out there, and dieting doesn't mean we have to throw it all out, but in the weightloss portion of dieting, less is more. Until you get to a point to where more calories and muscle building is a goal after you have cut down to a good bodyfat %.
I still eat quite a bit on our Zevist Holidays, thats in the cookies and cake department too lmao, but I still maintain workout schedules every day, at minimum half reps for everything. I also still keep my physique at this point. I believe a limitation on the days of feasting if you will, likely should be pursued if you have a goal to accomplish, or refrain from stuffing yourself with anything but lots of protein as the top priority, which I also do haha.
Some notable effects within the first month of this, though, I have been dieting a decent amount of time now, has been that acid reflux pretty much goes away and the pukey overwhelming feeling that comes with it. This would happen to me, even when lying down, it was terrible. 10/10 do not recommend, but we are far away from that now. My energy levels shifted for the better, and perhaps that is that the body is really starting to excavate and burn off the fat. The fat is of course burned off in a % from everywhere on your body, spot loss is not a thing. This is another reason why i have avoided the scale for the most part and introduced the mirror later on in moderation. The scale can become a habit that can be more destructive, similar to the mirror, and in the beginning as you already know where you are, and so you need to do the work on where you want to go. Hyperfocusing on how you look now kind of hurts moving forward where you actually want to be I have noticed, but at the same time, do your best to feel good that you are now making the right decisions to move forward and improve yourself. Moderation is important here, and it is a combination of finding what is wrong, then formulating a solution to fix what is wrong, then living in that solution, perhaps finding better ways from there.
If there is health issues involved, which in my case fortunately there has not been, you could go to a doctor to ask on this first.
As far as how far to go, I am personally going to go until I am comfortable with the results, as low as possible without any negative side effects. I would imagine this would vary from person to person. Then reintroduce higher amounts of protein and carbohydrates to begin shifting to steady muscle building on a level where the body is better suited for the task.
That is my bit on that, I will be interested in testing muscle growth after I have dropped my weight even more, that will be a new experience considering I have never been this light with as much muscle as i have accumulated.

With low fat percentage it will be easier to zero in on muscle groups and imbalances that I wish to rectify and grow.
I am not gong to take away from the recommendation of supplements, but I have done without, only relying on eating and drinking well. Protein powder is pretty expensive in those tubs too, along with protein bars.
Take Care, I have been meaning to post something like this for a little while now, so now I have. I hope that with some good reasoning in applying what I have posted, some good can come out of this for you and others here.
Hail Satya.
Hail Zeus.
Hail Andras.
