The other more common reason is that you are putting on weight. Tight Undergarments Your undergarments give you the first fat gain symptoms. When your bra strap suddenly seems a lot short and your lingerie is too tight for you, it could only mean that you have gained weight. Double Chin Your face is one of the first places on your body where you put on weight. If you suddenly start noticing a double chin, it is a definitely sign that you are getting fatter. Some people have a tendency to have double chin, but it always gets much worse with weight gain. Jammed Rings When your rings suddenly seem too tight on your fingers and you have literally struggle to get them off, it is time to hit the gym. Old Photos Your old photos can be the best eye opener ever. If you take a photo that is about one year old and compare it to your present photo, you are bound to get the hints that you have been busy gaining weight. The Dancing Belly When you gain weight in an unhealthy way, you will be gaining only loose fat.
