If you are a dieter, I’m sure you know that there are both good and bad foods for a six pack abs diet. The key to burning fat and getting a flat stomach eventually boils down to your ability to differentiate between the two and make the right foods choices everyday.

Foods that are considered good for a six pack abs diet will turbo-charge your metabolism, while those that are deemed bad will make your body prone to storing fat and your body structure soft and flabby.

Steer clear of these 12 worst foods for a six pack abs diet that I have listed below.

1) First on the list of the worst foods for a six pack abs diet is margarine. It is loaded with trans fats, which are the worst kind of fats that one can ever eat, and it has a high caloric content. Health problems, including cancer, high cholesterol, and heart disease, have been associated with eating margarine.

2) White bread is devoid of all the nutrition that whole grain bread provides, making it one of the worst foods for a diet. It should serve as a complex carbohydrate, but it acts more like a simple sugar; as a result, white bread raises your insulin levels and causes your body to store more fat.

3) High in trans fats and carcinogens, French fries are also one of the 12 worst foods for a six pack abs diet. Many health experts suggest that even moderate consumption of French fries could be harmful for the body.

4) Next on the list is processed cheese—one of the worst foods for a six pack abs diet. With almost no nutritional value, processed cheese is rich in fat, salt, and calories. In fact, the law requires that most manufacturers of processed cheese label their products as “cheese food” or “cheese product.”.

5) Whole milk contains 3.7 percent fat and, per glass, has twice as many calories as skim milk. Choose skim milk over whole milk for the best results.

6) Also on the list of the worst foods for a six pack abs diet are bacon and sausages. One slice of bacon has about 100 calories, and to top that, most of these come from fats. In addition, the nitrates in bacon are converted into cancer-causing agents, so bacon must be avoided.

7) Cookies and crackers are definitely one of the worst foods for a six pack abs diet that you can eat. Eating a whole box of these is not a difficult task, albeit they have no nutritional value. Just like white bread, they are high in simple sugars that keep your blood sugar levels unbalanced and contribute to fat storage.

8) You’ll want to steer clear of high-sugar breakfast cereals as they are most definitely not good foods for a six pack abs diet. If you want a healthy breakfast cereal, look for one that’s made from 100% whole grains and is completely sugar-free.

9) Commercial peanut butter is one the list of the 12 worst foods for a six pack abs diet because it is high in fat and very calorie dense. Rather than eating commercial peanut butter that is loaded with unhealthy additives like hydrogenated oils and high fructose corn syrup, its better to consume small amounts of natural peanut butter.

10) Everyone knows that donuts are not good foods for a six pack abs diet. Packing on pounds is easy if you eat one of the worst foods for a six pack abs diet of any kind—the delicious donut, which is high in fat, sugar, and calories.

11) If you’re drinking most of your calories, you should know that this is not a very good idea; in fact, soft drinks should be avoided altogether when you’re following a fat-loss program. These are loaded with sugar and calories, with zero nutritional value.

12) Most of the calories in ice cream come from a combination of saturated fat and simple sugar, and you should know that ice cream dishes have a lot of calories. Ice cream also contains artificial flavorings, preservatives, and fillers; obviously, it is one of the worst foods for a six pack abs diet.
