Simple Ways to Eat Healthy

I’d like to start eating healthier. I want to fuel my body with healthier stuff, lose weight, and maybe build some muscle. I’m willing to work out, and I’m willing to eat stuff besides my favorite (unhealthy) foods. But what I’d really like to avoid is putting a ton of time and effort into what I eat. I feel like I’m busy enough, and I also feel like I would quickly lose interest if I had to track a bunch of vitamins and stuff.

Is there any way to develop better eating habits without putting in a whole lot of effort?
