Is it normal that i'm a 23 year old male 5'7" and weigh 108 with 4% body fat?
Almost 23 years old. I'm 5'7" and currently weigh only 108 lbs with a body fat of 4%. I don't do anything to be this lean. I eat normal actually I eat pretty damn unhealthy but my weight never seems to fluctuate up or down. Been super light all my life and Ive always been extremely active with sports i.e. boxing karate kickboxing etc. I started eating healthy and worked out for a year and was only able to put on 8 lbs and reached 115 with the same body fat. If you look at me you would never guess I'm 108. You'd give me 120 at the very least. I'm not exactly skinny but lean instead. I look fairly muscular probably due to not having any fat on top of my muscles.
What is it in my body that I'm like this? I can't gain weight and I can't lose weight.
