I'm not going to eat at regular intervals
Is there a reason behind that?
I feel I can change my weight this way.
There is no one stopping you from doing that. You should make sure to eat in a healthy pattern, though. A diet like intermittent fasting can be good, but starving could be harmful.
I should have the right to not eat at regular intervals.
You definitely have that right. It's best to do it in a healthy way, though. It's healthiest to listen to your body's cues and maintain a safe eating habit instead of focusing on weight.
