I've never corrected my eating habits (well I did to some extent) but lost the weight anyway 4 years ago when I picked up cycling. Went from 208lbs to 150lbs at 5'7". I do the usual -/+5lbs depending on season so I've been 150-155lbs for a good couple years and change now.
I know 150 lbs isn't super low for my height as someone who rides 10 hours a week with 2 interval sessions per week, 4+ hours weekend endurance with some threshold efforts and couple of recovery rides every week but my main goal is not that number. It's my body composition. If the number comes down, great. I'll climb faster

I've hit a point where for all that work, it is kind of annoying to not have at least a low double digit fat percentage. I never measured it but I still definitely don't have an athletic build. Legs are rock hard. Arms skinny. Flabby stomach. I mean not just flabby. I feel 90% of my fat is in my stomach and chest area.
I know one way to tackle it is weightlifting and upperbody work but I really, REALLY hate every minute I spend in a gym. I'm not looking to be a chiseled greek god (Dennis Reynolds? Anyone?). I'm also aware that my genes aren't helping me much here. Just wanna loose some of the flabby parts and have realistic expectations.
This is my day one of not necessarily calorie cutting but careful what and when you eat plan. I will be eating most of my foods 2-3 hours before rides and jels/bars/etc on the bike depending on length of ride. Rest of the day will be healthy snacks and meals in moderation with light dinners and nothing after 7pm. See where that takes me.
Chip in with your experiences. Have you been stuck in my position and made a breakthrough?
EDIT:
After reading some posts here and deciding I need to work on some upper body strength training if I wanna see a significant change in my body, I signed up for a climbing gym.
Ok... Sooooooo... this is probably the best decision I've made since I picked up cycling in 2015.
I went to the climbing gym I signed up for with my girlfriend tonight. This was exactly what I was looking for.
I'm challenged by it. I have a lot of fun doing it. My upper body is DESTROYED in the best way possible. Gonna hurt like hell tomorrow.
I can NOT wait to go back.
Plan is to do it on my off days from the bike but honestly, I can see right away how I'll be tempted in rainy days to just climb instead of riding.
If I keep at this, I'm pretty sure my body will eventually have to change its composition a bit. Can take years but 4 years gone like NOTHING while riding. I'm sure same will happen while climbing too.
Thanks for all the input guys.
