Counterpoint - when I started working out, I started feeling less hunger and ate less automatically. Shit's connected. Just start somewhere, don't think about what's the most efficient and just do it.
Well, the narrative is that fat people are lazy and simply need to exercise more to lose weight. But this is not scientifically true. I'm posting this video again because it summarizes the scientific study situation in just 6 minutes.
Nah, I just felt like a non-verified personal anecdote that tells you the opposite of scientific facts should be corrected. I found the video while looking for a quick, credible proof and edited it in my first comment because it is exactly what I was looking for.
You still need to workout if you live a sedentary lifestyle. Research has shown that being sedentary has a worse effect to health compared to smoking. Also, don't forget about the mental health benefits to working out.
