Lots of possibilities – Here are just a few:

1) “Hormonal” type drugs, such as Prednisone and Depo-Provera, can cause weight gain.

2) High sodium diet – ie. Campbell soup, “Soup is Good Food” Sodium attracts water and will add to your weight. You will be surprised that alot of foods labeled as “Healthy”, “Nutritious”, “Whole Grain”, and “Organic” are actually bad for you. The best way is to calculate just how much sodium you are taking on a daily basis. It should not be more than 2000 mg per day.

Do note that a low sodium diet (below 1000 mg per day) can lead to a lack of blood flow and make one more prone to infections.

3) Insulin Sensitivity – Even if you are not diabetic, this is something worth paying attention to because this will tell you just how well your metabolism is working. The norm is that after a carb meal, the insulin will respond quickly. A diabetic will not respond to insulin after a carb meal without some medical intervention.

How do you tell? Eat some white rice and look at your tummy. If your tummy bloats and stays bloated for a half a day, you’ve got some concerns and may want to talk to your doctor about it. Ask the doctor to administer a random blood glucose as oppose to a fasting blood glucose test.

This will indeed tell you if your metabolism is working well or not.
