Some fat has receptors that make it easy to burn, while stubborn fat has receptors that slow down burning, especially in the lower belly and hips.

“Part of the reason for this is not all body fat is created equal. Certain fat on your body is packed with beta receptors, which you can think of like a gas pedal, making it easy for your body to burn for energy. Most of the fat you burn off up to this point are from those areas. Whereas the stubborn fat left on your body is full of alpha 2 receptors, which instead work like a brake pedal, slowing down fat release. So your body always has some fat reserves to rely on. And typically the areas that have most of these receptors are going to be your lower abs, love handles, hips, and especially the glutes.”
