You're wrong, and the science backs that up. Come back when you have peer-reviewed studies to support your argument.
This research demonstrates that exerting self-control in one area can deplete a person's "willpower" resources, making them less able to resist temptations, such as unhealthy food, in subsequent situations, regardless of their mood.

Three studies were conducted to test the behavioral consequences of effortful self-regulation. Individuals with chronic inhibitions about eating were exposed to situations varying in level of self-regulatory demand. Subsequently, participants' ability to self-regulate was measured. Two studies...

This study links higher consumption of ultra-processed foods to structural changes in brain regions that regulate appetite and reward, suggesting that the very design of these foods can rewire our brain to encourage more eating, independent of conscious choice.

This research shows that after weight loss, the body experiences persistent hormonal changes (e.g., increased hunger hormones like ghrelin and decreased satiety hormones like leptin) that actively promote weight regain, making sustained weight management incredibly challenging even with conscious effort.
