Common food allergies such as peanuts, milk, and wheat can make you feel itchy, nauseous, or even gasping for breath. Being sensitive to food on the other hand can cause stomach cramps, bloating, and discomfort. Those who are sensitive or allergic to certain foods may report feeling lighter in weight after avoiding trigger foods. A recent report states that being allergic or sensitive to foods may not make you gain weight directly. Due to bloating, discomfort, and not feeling well, such conditions can make your pants feel tighter and make you feel less like engaging in exercise, which in turn can lead to weight gain. This study suggests that those who are allergic or sensitive to food can avoid such trigger foods to feel better inside and out.
