Although we know we can't target where weight comes off, if someone gained 20 pounds of fat and then lost 20 pounds of fat with no muscle gain or loss, would they look the same as before? Could it go on the stomach but be lost from the butt?
In my training I tend to have periods when I deload and just enjoy all kinds of food. That would typically happen during holidays when I give my body full rest for couple weeks. At these moments I gain enough fat to lose any track of my six pack(which happens to an extend because of muscle atrophy as well) and then after I get back on track I am quickly getting rid of all fat once again.
I have noticed and pointed out on many occasions that I tend to gain fat in a certain manner and lose it the same way. For example - I firstly put fat on the sides of my stomach, then on my abs, then on my arms. When I lose fat it starts from my arms, then my abs and lastly lose the fat from the sides and lower back.
I hope my answer helps you. :)
