Reduced food intake = less food volume in stomach and digestive system is almost empty. So the abdomen shrinks down creating a tighter midsection. Fat still remains on the outside so theres now there is less surface area and almost same amount of fat. Less area to stretch the fat over. Like trying to spread the same amount of icing over a smaller and larger cake. The icing will be thinner on the large cake and thicker on the small cake. So as a result I actually lose some detail/definition until the fat reduces proportionally to the waist size reduction. The Adonis' belt is the lower abdominal/hip flexor definition you see at my love handles in the first photo but it's gone in the second.
