Is it bad to do weight lifting and not do cardio at all? Will that really effect me or will ti mean it will be easier to bulk?

Muscle breakdown is extremely inefficient and in itself takes energy. To use muscle as an energy source it must be broken down into aminos, then stripped of the amine group so the useful CHO's can be used, then those CHO's have to be turned into glucose where it can THEN be used as energy.
The body would much prefer to use the glycogen already stored and ready for use in the muscles, as well as the fat that only has to be stripped of the glycerol which can be used for energy.
Using muscle is somewhat of a last resort. There is speculation that the body starts getting rid of muscle to make you lighter so as to make the job easier, but I don't really buy that.
Long story short, there are too many mechanisms for energy for the body to resort to the least efficient of them all. Do cardio, it's good for your heart. Don't do it on lifting days, however.

Because weight lifting is an anabolic process, and cardio is catabolic. You don't want to force your body to be catabolic when it should be anabolic (post workout when the body starts recovering).
I've seen many guys do some light-moderate cardio for about 10 minutes post workout. That should be fine. Just save the more intense cardio for your off days.

I am not the right person to post here since I am on a double edged effort to lose weight and gain muscle but losing weight is a priority. I will give my 2 cents anywayze. What I noticed is if I am giving in equal efforts of both my body feels fine, better actually. But every now and then I go a week or two focusing on just one of those things ( just a way to mix things up)...so during the week I only do weights and no cardio my body feels a lot heavier and muscles and back ache a lot more
... so yea to answer your question cardio is deftly good. Bodybuilding is not natural you are forcing your body to grow beyond its original mass (same with obesity) so you need to give your skeleton and bones a break by reducing fat. They dont want to have carry out extra baggage all day

im sorry but thats the most stupid thing ive ever heard, when you lift weights your muscle fibres tear then your body uses protein to repair the micro tears and overcompensates and add a little more on to adapt to that certain weight. how that is not natural i don't know its just the bodys way of adapting of the stress/demand its put under
exactly the same principle with wolffs law and bones☆☆☆UK Crew☆☆☆
