You don’t have to exercise to lose weight, you don’t even have to drastically change your diet.
Eat. Less.
You can lose weight on a diet of pizza, donuts and laying on the couch if you simply eat less calories than you burn.
You quite frankly sound like one of the many enablers that wants to make every excuse possible about why it’s impossible to lose weight rather than taking responsibility for the countless poor eating decisions that lead to obesity. No one is born fat and no one wakes up fat, take responsibility.
