I actually think its is even advisable or better recommended. I love me some chicken, however you can get quite sick of it especially on this diet that is supposed to have lean protein. Off course for chicken all you need to do is cut out the skin and you are set. Chicken is also very versatile you can have it as salad, in stew . roasted, boiled, grilled. They are just so many things that you can do with chicken, if you are in a Country where you can get it cheap you are very lucky.
For me chicken is preferred too - I find it's cheaper, more versatile, and I just like the taste of it! Similar to a lot of others who already commented, I use it for salads, on its own with veggies and quinoa as a side, stir fried and more. Loads of options for ways to use it!
Well chicken specially the breast part is high in protein and i think its good for your diet. Also you can try chicken based soup as an alternative for heavy meals. Because soup has more liquid than meat, its great for diets because you get to re hydrate and have all the nutrients infused in the soup.
