Regardless of how much you work out or how much you deserve a “cheat day,” there are some things that should still be forbidden. Tim McComsey is a registered dietitian and weight-loss specialist, and shared with Men’s Fitness 8 food to avoid at all costs: I had 6 out of 8 of these this wknd. Whoops!

1. Doughnuts
The amazing taste of donuts don’t come without an enormous cost to the body. These sticky and sweet treats are high in calories, fats, and carbs. Plus, because of added preservatives, they can sit on store shelves for extended periods of time without losing its taste or spoiling. The result? Rapid weight gain and poor digestive function.

2. Bagels
Bagels have a massively high glycemic index which increases insulin and inflammation in the body, as a result, the possibility of accelerating aging, worsening acne, and rosacea. One bagel alone often contains 2-3 servings of carbohydrates, so the added pounds will come on quick.

 

3. Sugary Cereal
Want a surefire way to ruin your body inside and out? With the the high amount of inflammation-causing sugar and gluten content, most cereals will do the trick. Gluten alone can increase skin breakouts and inflammation of the stomach lining. Skip out on the sugary cereals if you’d rather spare yourself the gut-aches and crummy skin.

4. Chips
Most chips are deep fried with trans fats that can increase cholesterol levels and increase the risk of coronary heart disease. Trans fats are made by adding hydrogen to vegetable oil through a process called hydrogenation, which makes the oil less likely to spoil. Using trans fats in the manufacturing of foods helps foods stay fresh longer, have a longer shelf life and have a less greasy feel.

 

5. French Fries
Just like chips, french fries are often, if not always fried in oils and trans fats. The potatoes themselves are high on the glycemic index leading to an increase in insulin levels which are both harmful to our health, and our waistlines. French fries, along with chips, contain acrylamide, a known carcinogen that is formed when foods are baked or fried at high temperatures which is known to cause cancers.

6. Fast-Food Burgers
It’s approximated that the meat used to make burgers is 2% or less actual meat. The other 98% of the burger are industrial chemicals that our bodies are highly unlikely to use at all. These chain-made burgers are also high in saturated fats, and may even contain trans fats.

 

7. Microwave Popcorn
Microwave popcorn contains carcinogens, cancer-causing free radicals in the bags that holds the kernels. Perfluorochemicals, or PFC’s, are added to the bags to make them more greaseproof even though they’ve have been linked to thyroid disease and ADHD, among other illnesses. Another cancer-causing chemical, diacetyl is hidden in the artificial fats.

8. Margarine
Margarine is marketed as a cholesterol-free, healthy alternative to butter, but it’s the ultimate source of trans fats, which actually elevate cholesterol and damage blood vessel walls. To play it safe, read food labels to make sure the foods you’re eating use omega-3 fats or butter over margarine.
