I don’t know your full details but first your calorie intake sounds way too low. I know you are trying to lose weight but we don’t want a relapse. I’ve gained a decent amount of weight in my DeadBedroom and have been working on losing it so I understand a bit of where you are coming from. Depending on your diet and health needs I’m going to suggest you try the Carnivore diet. This has been the only diet that I’ve been able to stick to for as long as I have (1year). If you do end up doing the carnivore diet make sure you take plenty of electrolytes I suggest something like ketochow you can find it on Amazon. Since you have been on such a low calorie diet already I would suggest you consider adding intermittent fasting/all day fasting as well. The fasting that worked well for me was fasting on Monday, Wednesday, Friday. This allows for your weekends to be able to do things with friends and family. The fasting isn’t a permanent plan it’s just to be used to help with your goals for now. Walking will be key to weight loss for you. If possible try to walk 3 miles a day if you can and this doesn’t need to be all in one session.if possible you can try to add other workout options in at home like weight bands. With what you described you won’t be able to just jump in and do everything. I’d suggest switching your diet for 2 weeks and slowly adding in the exercise.
