Hi and thank you so much for this query. I am so sorry to hear about this weight concern that you have expressed. For real, your BMI is less than 18 which is considered to be normal and desirable above this. With you eating right per your evaluations, I will suggest that you follow up with a dietitian to see if you do eat enough calories adjusted for your daily activities. There are also conditions like diabetes, hyperthyroidism, etc. that may cause weight loss. They would also be investigated to make sure we are not missing out on something here. I hope this helps. I wish you well. Feel free to ask for more information and clarifications if need be.
