You should avoid to eat these foods
Dairy
via agrodaily.com
Dairy products like milk, ice cream, or frozen yogurt are common ingredients in smoothies, but they are chock full of extra calories. There are exceptions, such as raw milk and plain, full-fat Greek yogurt, which is high in protein and low in sugar, but most dairy should be avoided.
Fruit juice
Juice is often high in sugar and calories and low in nutritional value, especially store-bought products. Many contain added sweeteners, and all have lost the fiber of the whole fruit. A limited amount of 100 percent juice is fine, but too much will just increase your total (bad) calorie intake.
Canned fruits or vegetables
Fresh produce is always best, but when you can’t find what you want, turn to frozen foods before cans. Canned fruits and vegetables often have added preservatives or sweeteners that increase the amount of calories. They have also lost a significant amount of their nutritional value. Fresh and frozen veggies and fruits maintain nutrient content much longer than canned products.
White Bread
White bread is highly refined and often contains a lot of added sugar.
It is high on the glycemic index and can spike your blood sugar levels
One study of 9,267 people found that eating two slices (120 grams) of white bread per day was linked to a 40% greater risk of weight gain and obesity.
