Hi
@TonyBlue,
Were you able to eat when you had the virus? Some illnesses take away all appetite and give extra symptoms if food’s eaten. You may find that your weight creeps a bit up naturally now that you’re well.
If you want to add to it then maybe having a bit to eat between meals would help: just bolus for any carbs. Also, try piling a bit more on your plate or adding an extra something at lunch and dinner.
You don’t say what kind of things you’re eating now so it’s hard to suggest just what to add for weight gain.
Good luck.
