I am 33 yrs old. Height is about 5'10. My current weight is 63 kgs. I was 76kgs or so about year and a half ago. Then I was diagnosed with hiatus hernia. Hence I started having smaller meals and my weight reduced to 68kgs. From last couple of months, it has gone down to 63kgs. I wish to increase it just a couple of more kilograms in order to not look very thin. I follow a vegan diet. Please someone point me in the right direction.
