French Fries

A larger portion of fries (around 170 grams) has almost 550 calories and about 259 grams of fat. A tub of French fries will easily make you fat since an adult should have only about 65 grams of fat per day. If you eat a large serving of French fries and a mayo-laden burger at McDonalds, you'll be consuming almost 1500 calories. That's the maximum amount of calories you should be having in one day in a single meal.
Diet Foods

Many foods claiming to be diet-friendly are actually hidden calorie traps packed with sugar and syrups. In fact, ‘healthy’ cereal bars can contain as much fat, sugar and calories as an average chocolate bar. Research by the Texas Health Science Center at San Antonio found that those who consumed diet drinks daily experienced a 70% greater increase in waist circumference than those who drank none.
Salad Dressings

There's nothing better for you or your waist than naked veggies, but the shredded cheese, candied nuts, croutons and globs of dressing often make salads as caloric dense as an oversized dish of pasta. And nutritionists are quick to point out that innocent-sounding vinaigrettes, though not as fattening as ranches, can have almost as the same amount of high-calories.
Potato Chips

The results of a new study in the New England Journal of Medicine about weight loss will blow your mind. By analyzing the eating and exercise habits of 120,877 people over many years, the doctors concluded that downing a whole bag of potato chips makes one fat faster than just about anything else, ice cream and soda included.
Sugar-sweetened Beverages

Sugary drinks contribute to obesity because they are high in calories but don't satiate the appetite, and so people often do not cut back on the calories they eat to compensate for those they consume in liquid form.
Bottled Teas

Most store-bought brands are souped up with sugar or honey, which are very high caloric sweeteners. One bottle can contain two or more servings, bringing the calorie count to almost 200, similar to a bottle of soda.
Wraps

No matter what you put in it, the average wrap is a major offender packing up to 300 calories. Since the surface area is way bigger than two slices of bread, you coat it with a lot more mayo or dressing than you would a sub or sandwich.
Dried Fruits

Dried fruit has five to eight times more calories than the fresh kind because it has been dehydrated and made much denser. Fresh grapes, for example, have 60 calories per cup, while raisins have 460. Many brands add sugar, increasing the calorie count even more.
Veggie Burgers

Depending on what you put in your diet-friendly veggie burgers, you could easily end up housing more than 1,000 calories. The cheese that often binds the veggies together and the huge size of the burgers are anything but diet-friendly.
Bran Muffins

Whether it's plain bran or mixed with apples or bananas, the fiber fills you up, sure, but considering all the sugar and butter it delivers, a bran muffin is basically just a round slice of cake. One weighs about 20 grams of fat, 420 calories and 34 grams of sugar.
