If you plan your shopping list and stick to it, you are likely to be more successful in your weight loss goal. After all, if you are stocked with the right foods at home, you are not going to end up eating unhealthy foods every time you open refrigerator. Foods that are high in fat and sugar are not going to do your diet or your body any good. Hence, some form of advance planning on your meals will greatly help!
When you go grocery shopping, ensure that all the items in your shopping cart are only the items on your list. Avoid impulse buying while at the store. As long as the list contains only the food items that are allowable on your diet, there is no chance of going wrong.
Having some knowledge of what healthy foods are also helps in your selection. It is not enough to know which food items are OK to buy such as bread and cereal, fruits, vegetables, dairy, meat, fish and poultry, you must also know which kinds of these foods to purchase in each of these food categories. An example is bread and cereal, instead of buying just any old bread or cereal buy whole wheat or high fiber bread and cereal and instead of any cut of meat buy lean meats.
Having an idea of how you are going to prepare your foods is also important. In this manner, you also get the right ingredients for cooking. Go for the grilled fish, baked chicken instead of fried and forget the bacon and spareribs. Hence, ensure that you have the ingredients for low fat cooking.
Never, ever shop while you are hungry. Consume a healthy snack before leaving for the store, so that you reduce the chance of stomach grumbles that will tempt you to buy foods that are not on your list.
Avoid bulk buying as you may end up with too much food to stock up. Also pay close attention to coupons. The coupons are usually for food items that are the most fattening or that contain sugar. While it may appear that you save money with using these coupons, it may not really be so in the long run. You are saving money on health related costs associated with obesity issues.

I personally lost a good deal of weight(40 lbs) by simple diet and exercise. While I made a lot of changes to my life, the food impulses required a more drastic approach. I used Methadrene, I think it has ephedra in it, but I didnt see anything about it on its website http://vitabodyextreme.com/order-methadrene-25/ but Im very sure it has some. I also took a complete multivitamin as I was worried about not getting enough nutrients and minerals. I would jog a mile a day and follow up with some free weights. I would also eat less than 2,000 calories and drink lots of fresh green tea sweetened with artificial sweeteners. I dropped nearly 10lbs a month, and would of continued... but I ran out of vitamins and suppliments. Hope this helps someone
