I am not a medical professional, and I advise you to consult one. The following is my non-expert opinion based upon my own personal experience while seeking a healthy lifestyle.
Being hungry is not normal. Examine your diet closely. You may have sugar, oil (even vegetable oil), refined carbohydrates, or other processed ingredients that can sabatage an otherwise healthy diet. Avoid diet drinks because of aspartame. In fact you'd do well to avoid all drinks but pure water. MSG is in many foods as is high fructose corn syrup. Commercially processed foods can present you with difficult to diagnose problems because of the sheer number of added ingredients. Wheat and soy are common allergens. Make sure to avoid these and use non-gluten and non-GMO legumes. Sometimes processed foods add dairy and animal based food products.
Please consider a pure diet to see if there is something you are allergic to. I'd avoid restaurant food, convenience foods, and food additives. You have an enormous variety of legumes, whole grains (not processed and non-gluten), green leafy vegetables (kale, collards), whole vegetables, and whole fruits. Of course take B12 and get Omega-3, preferably from flax seed. If you don't get enough sun, take vitamin D.
There is something wrong if you are still hungry on a high fiber, high plant protein diet. Perhaps your naturalpath can do some blood work and help advise you.
Read Dr. Neal Barnard or Dr. Caldwell Esselstyn, Jr. for advice about a balanced and healthy diet. My high fiber diet allows me to eat a big breakfast and big lunch. I am never hungry and I never eat between lunch and breakfast the next day. My blood sugar level at one point was out of whack when I was eating six meals a day, but now it's as steady as a rock with just two meals. A period of not eating allows my digestive system to rest. (Dr. Joel Fuhrman) I understand that water fasts are common practice in other countries, but not in America. My ravenous appetite was stilled after a five day medically supervised water fast.
Of course, consult a medical professional with some knowledge of nutrition and alternative medicine.
