Greetings for the day!!
When our biological clock is affected, our metabolism gets affected. This leads to various problems like hormonal imbalance, weight gain, stress, inflammation in the body. Working night shift regularly tends to disturb our biological clock. We need to give more attention towards maintaining our body metabolism through a healthy lifestyle. This change to healthy lifestyle cannot happen over night, you would need the guidance of a qualified professional. You have also mentioned about
thyroid problem, hypothyroidism tends to slow down your metabolism leading to weight gain. A customized diet plan from a nutritionist will help you loose weight easily.
Thank you
