1. Refined Sugar

Sugar digests almost instantly and goes directly into your bloodstream. Insulin makes your body to convert the sugar into fat. The body’s fat burning process is shut down so that the sugar that has just been ingested can be immediately used for energy. The excess sugars are then converted to fat and, just like the fatty acids released from the liver, they are stored as adipose tissue on our waistline.

2. Whole Wheat Bread

Unless it’s made from actual whole grains, it’s just as processed as white bread. Often, the whole wheat has been ground into a fine flour that’s easy to digest and spikes your blood sugar just as quickly as white bread. Look for 100% whole wheat, whole grain or instead.

3. Cereals

Cereals are a good source of fibre, calcium and protein but if you are not reading the label carefully, your cereal may actually be causing you to gain weight. Read the label carefully, one serving of cereal should contain at least 3-5 grams of fibre. Avoid buying cereals that contain honey, chocolate, refined sugar. One of the main problems is that refined, simple carbohydrates are quickly broken down in the digestive tract, leading to rapid spikes in blood sugar and insulin levels. This can lead to carb cravings a few hours later when blood sugar levels go down again.

4.  Energy Drinks

Most energy drinks are loaded with sugar and caffeine and easily contain 100-120 calories per can. Most people, on an average drink 3-4 cans per day because it gives them quick rush of energy and big crash afterwards when blood sugar goes low, they feel totally run down and exhausted and want more sugar  so they have to drink an another one in order to keep going which leads to fat storage

5. Processed Foods

Processed Foods Are High in Sugar and High Fructose Corn Syrup. Refined carbohydrates like breakfast cereals, bagels, waffles, pretzels, and most other processed foods quickly break down to sugar in your body. This increases your insulin levels and contributes to insulin resistance, which is the primary underlying factor of nearly every chronic disease and condition known to man, including weight gain.
