I agree with @Blueroses. Portion control is the hardest part of maintaining a diet.
Three reasons: we are hungry for nutrients we don’t recieve so our body keeps “feeding” us the hungry signal.
The types of food we eat encourage use to eat more. Chemicals: msg, aspartame etc.
Packaging we eat what is in front of us without awareness or taking the time to monitor our fullness. Starts with childhood clean your plate to prepackaged foods and busy daily lives.
Obviously I agree with @livelaughlove21 on this. Eh I like carbs and think they are necessary though. It is more diet. If you don’t have the proper fuel how are you going to be able to maximize and maintain goals.
Also worth noting muscle adds weight. It speeds up your metabolism and changes you shape so clothes fit better. But if you are going by weight alone there will be plateaus and sometimes you might even gain. But in a good way.
Every one is different. And exercise releases endorphins which raise seratonin levels. Which might work to make you eat less and be more conscious about what you put in your body.
I would say 67 diet and 33 exercise for me.
