According to a Harvard study conducted over twenty years, these 12 foods have been linked to a significant increase in weight... and combined, contributed to an increase in 17lbs. over 20 years. Sounds not-so-bad, however, the study was performed on 120,877 non-obese people. For each four-year period, food choices contributed to an extra four pounds while exercise cut less than two pounds.
1 = an increase of less than 1lb. a year
12 = an increase of ~2lbs. a year
3 - fried food
4 - refined grains (white rice)
5 - sweets & desserts
6 - potatoes
7 - trans fats
8 - processed meat (bacon, hot dogs, etc)
9 - unprocessed red meat (beef, steak, hamburger)
10 - sugar sweetened soda
11 - potato chips
12 - french fries
Naturally, I'm upset because french fries (ranked #12 here) are the worst food you can eat and simultaneously one of my favorite foods of all time. I just hope that pairing it with an unnatural amount of ketchup keeps my heart and waistline safe.
