Hey Claireelis
What you are describing with your body temperature and slow bloodflow thru your hands (cold hands) could be due to a slow thyroid. Have your doctor tested you for this? Because an underproduction of thyroid hormones gives you cold feet and hands but also often causes a mild or sever depression, hairloss, acne, slow circulation (and about 100 less kcals/day burned). People with a slow thyroid often gain weight but NOT due to a very slow metabolism, that is a myth, the real cause for the weightgain is that the need to comfort oneself with food increases because of the depression. Get tested so you know, its easy
Your cold hands and feet could just be due to slow circulation tho, wich is nothing to worry about, we are all individual, some people just naturally have colder temperatures than others. And as RRM said, its another big fat myth/missunderstanding that the fatburning metabolism remains low for a long period of time after youve stopped with your eatingdisorder. The body is a remarkable machine when it comes to adapting to calorie intake right away, and also the heavyer you are the more fat(calories) you burn all day long, so actually heavvy peoples basic-metabolism always burn more than skinny ones. And if you have lost alot of muscles you will get your bodys healthy normal musclemass back as soon as you start eating normal again.
When it comes to excercise, only do it if you think its fun and it gives you a feeling of well beeing, my personal experience is that most people Ive trained with gets really hungry from weightifting and you might end up gaining fat or struggling as h*ll to just maintain the caloriebalance. This is because of when you do weighlifting or intervalltraining the body releases growth hormones that stimulates overeating to secure growth, and those hormones will make it harder for you to loose the weight. So rather choose walks or something similar.
