Healthy Male, turning 29 in a couple of months. My weight does not increase beyond 45-48kg. I've always been underweight as a child. My height is 5'7".Perhaps a contributing factor to my issue is the fact that I've seen eating as a chore and have never had a perticularly healthy appetite. Where others my age can eat twice as much I simply get bored of eating and just eat a bare minimum. I don't exercise or do sports but I do enjoy cycling. Unfortunately I do feel I am more lethargic and less physically able than others my age. Although I am a relatively happy and content I do feel that this issue of being under weight has leads to a lack of confidence in some aspects of my life. At this point in life I feel I need the professional guidance of a qualified nutritionist, preferably male, as I would like to get this issue sorted. Any guidance would be very much appreciated. Thank you for your time.
