From what you have stated, you are appropriately 30lbs overweight. You did not state your age so I am not sure how many calories you need a day. If you want to lose weight, it is done by eating healthy and exercise. You need to do is increase your physical activities to 1/2 hour or more a day. That 1/2-hour or more can be broken up through the day, 10 minutes here and 20 minutes there. For example, park your car in the back of the parking lot and walk to the store. That will give you additional walking. The foods you eat should come from other the food groups multi-grains (not wheat), fruits and dairy / meat. Eat low fat meats (chicken, fish, loin of pork) or non meat sources (soy products), low fat vegetarian combinations (rice & beans, pasta & beans, low fat cheese & pasta), fat free or low fat dairy products (skim milk, 1% milk, low fat cheese, low fat yogurts, low fat soy milk/yogurt), and eat a lot of fruits and vegetables. Eating daily high fiber breads and cereals (oatmeal). Eat 3 small meals a day with small snacks between meals. Portion control is important and here some general tips = ½ cup for all starches and vegetables; one piece of fruit or ½ cup of small fruits; 1 cup for low fat dairy products, and only 3oz of low fat meat or protein substitution a meal (only 6ozs total a day). To help eat less food pre-meal, eat about 7-10 almonds, 20 minutes before lunch and dinner so you will feel full faster and not eat as much food. Do not be discouraged, weight loss can be a slow process but the slower you loss, the higher chance it will stay off. Think of this new way of eating as your new healthy lifestyle and not as a diet. That will help you to keep your weight off, and keep your body healthy. Hoped that helped you.
hmm.. im not expert at this, but maybe you should try cutting calories not carbs..roughly for you(weight and height) you calorie intake should be 2000 to 2500 a day. and i was really surprised from what my calorie intake was before..but you dont have to take my advice,just trying to help!!!
good luck
