I think I have a way for you to get out of this situation.
Fat storage in the body is controlled by insulin. If you have a lot of insulin in your blood then you store fat. When you can drop the insulin levels then you can burn fat. Insulin gets released into the blood stream when you have high blood sugar. And you get high blood sugar when you eat carbs - sugar, but also bread, wheat, flour, pasta, rice, potatoes, etc.
So don't eat carbs at all!
That'll keep your insulin low and you'll burn fat.
Now eat plenty of non-starchy vegetables - green beans, broccoli, brussel sprouts, cucumbers, lettuce, cauliflower, asparagus, carrots, kale, etc. These are packed with vitamins and have low calories. You need low calories now because of your slowed metabolism. The vitamins will tell your body that the starvation period is over and they will start speeding up your metabolism.
So you should be eating platefuls of non-starchy vegetables and no carbs - do this for breakfast, lunch and dinner. It's very hard to consume too many calories if you're eating non-starchy vegetables.
You need to also include a moderate amount of protein per day. 2 grams of protein per kilo of body weight per day. Also split this over three meals. Bacon is a good choice for breakfast.
As your metabolism starts to improve you might find yourself getting hungry. That's the best sign that your metabolism is improving. When you feel hungry after your vegetables and protein do not start eating carbs. Instead eat some good fat - eggs, nuts, avocados, cheeses.
If you can do this you'll continue to improve your metabolism without spiking your blood sugar. You lose the weight you need and you'll fix your metabolism. You'll feel a whole lot better.
