Hey, welcome to the group!
Are you doing any training right now? Weight training, cardio, or sports?
Those will play a role in how muscular or how lean you are and can help tone up.
As far as eating, I would take in more calories, especially if you are doing some training. I know a lot of us on here eat between 3000-5000 calories a day, but we also train so it doesn't get stored as fat.
I would focus on eating clean foods, natural, whole plant-based foods.
For me, I stay in pretty good shape all year round and I pretty much eat the same style all year round. When I get ready for a competition (bodybuilding) I cut out the junk foods like vegan ice creams, cookies and stuff like that.
I like to focus on fruits such as oranges, apples, bananas, berries, peaches, etc.
I also really like vegetables like broccoli, spinach, potatoes, carrots and others.
Beans are great also and I eat kidney, green, garbazo and pinto beans on a regular basis.
I also eat nuts, grains, seeds, some tofu and soy products too. I take barely any supplements, mostly just a multivitamin and vega (www.myvega.com
Best of luck and I'm sure others will give you some great ideas as well.
Take care and please stop by the introductions page and introduce yourself to the group
