First of all, your colleague's remarks are definitely harmless, and at best they are joking, provided that the relationship between your is relatively good. For a person, body management has always been an increasingly important issue, especially with the growth of age, more and more attention will be paid to health and body shape. After all, no one wants to be pointed at by others, especially those with relatively fat bodies. The general intuitive feeling for most people is that they can't control their mouths, and then they will think that their self-discipline ability is poor, and a series of bad impressions will emerge immediately. He will say this, in fact, he is willing to risk being misunderstood by you, and kindly remind you that in the long run, he still cares about you.
In addition, please pay attention to your diet, work and rest regularly, and exercise frequently, which will be good for your health.
I hope so. Thank you.
