The calories in chicken thighs vary depending on the brand and the way the chicken was reared. Most boneless, skinless chicken thigh comes in between 30 and 60 calories per ounce.
Calorie counts for natural products are always subject to variation, and chicken is no exception. Because calories are usually given by weight, the calorie amount is influenced by whether the chicken is raw or cooked when weighed. The calorie count also varies widely depending on the provenance of the meat, the amount of water added during preparation and the method by which it is cooked. However, skinless chicken thighs typically remain a relatively low-calorie, high-protein option.
