Calisthenics Unity

Hello!
So i've been eating a lot for about 2 months now and i've gained 3kg.
I've been getting stronger and stronger but i'm noticing my veins aren't as visible as they used to be.
I had visible shoulder veins when i wasn't flexing and now i only see them when i flex, i've also been gaining fat on my belly and over core
In short, i want to get that vascularity back, get rid of belly fat(not so improtant cause there isn't much)
What can i do? I still want to build muscle and i have to eat alot to do that but i mean there was to be something.
Thanks!

Run at least one mile three times a week. Or do Chris's fat-burning routine that you can find on YouTube. Bottom line, at least three cardio sessions a week. You could do this:
Sunday: Run one mile
Monday: Full-body workout
Tuesday: Chris's fat-burning routine
Wednesday: Full-body workout
Thursday: Run one mile
Friday: Full-body workout
Saturday: Chris's fat-burning routine

And then start with the full-body workout on Sunday and then take it from there, I already set out the pattern. But it all depends on how you are feeling, too tired, too sore, too busy! Hahaha. Another thing, if you don't want to lose muscle, eat...........like.............a............panda. Hahahahaha, no really, I've heard that they spend like 90% of their awake time eating😂😂😂. Now I don't expect you to eat like that, but you get the point. Eat in calorie surplus to gain mass(let's hope in muscle) and do cardio to lose fat(and show veins, lol). Really, it's a win-win situation. Lose fat, gain muscle=lean bulk. It will take a while though, but it'll be worth it. Good luck!!!

P.S. Protein to gain muscle, especially after Full-body workout and right before going to sleep!

Great reply from Daniel. Well I do one thing for cutting, but I don't know if you can handle it or if it's the best way to go for you: Intermittent Fasting. You fast for 16 hours and eat your calories in a 8 hour eating window. This way the hormones that store fat are low, HGH is boosted, and another hormone that preserves muscle mass is also boosted (according to a few videos and researches), so you burn more fat.
But the best thing is to be in a slight calorie deficit just so you can burn fat but you can still eat a lot of the nutrients to preserve the muscle mass, which is the smartest way to go about it.

Cardio definitely helps at burning calories, start even with something light like 2 rounds of the Chris fat burning routine whether on YT or Plus which should take around ~8 minutes, like Daniel said, and add up if needed.
Well I've seen people cut with one meal a day (Post workout) (Little to no muscle mass lost), and people cut with 6+ meals a day (Same thing with the muscle mass). I don't think it matters when you eat as much as how much and what you eat (maybe exception for ectomorphs to get protein at night, but carbs after 7pm for example don't make you fat), but just really eat whenever you're hungry or whenever you need to accordingly. It's 70% nutrition 30% workout. Well I'd say it's 100% nutrition and 100% workout, as the quote says “The pain of regret is far worse than the pain of discipline."
