There are plenty of ways to give the impression that you take care of your body. One option, of course, is to actually take care of your body, but if that were something that interested you, you wouldn't be here.

So, instead, here are 12 alternative approaches to fitness and diet that require no real lifestyle alterations—but will convince the people around you that you've got it all together.

1. Wear a lot of workout gear.

It's cute, it's comfortable and it will make everyone think you're "Headed to the gym after this," even though you're totally going to get Andy's with your roommates.

2. Insist you don't drink soda when eating with friends.

Saying "I don't drink soda," is a not-so-subtle way of saying that you refuse to partake in one of the most unhealthy beverages available for consumption. Order a water with lemon, finish the meal, go home and crack open a Diet Coke in the privacy of your own home. Your caffeine dependency will be satisfied and your friends will be none the wiser.

3. Carry running shoes in your car.

"Oh, those? Yeah, I keep them with me at all times. For running."

4. Buy lavender scented home products.

Candles that smell like baked goods will leave house guests thinking of carbs. Candles that smell like lavender will leave them thinking of a yoga studio. Learned association—it's science.

5. Keep a fitness journal.

Leave it in plain sight while in class, at work or around your house. Write in it. Talk about it. Whip it out at brunch.

6. Tell people you're considering working out later, even when you know there is not a chance in the world you are working out later.

Friend: "What are you doing?"

You: "Thinking of hitting the gym in a few, what's up?" *Continues watching Netflix from bed for 3 hours*

7. Invest in a cool water bottle.

Show everyone around you that you take drinking water so seriously, you bought yourself a $30 receptacle just to do it out of.

8. Wear your hair in a pony tail more often.

It's sporty chic. It makes you appear to expect physical activity enough that your hair cannot fly into your face and impede your efficiency. It virtually eliminates any time needed to style your hair in the mornings. Win, win, win.

9. Shop at a health food store.

Nothing says "I avoid msg's and cancer" like a couple of Mama Jean's reusable shopping bags in your food pantry.

10. Carry around a green smoothie.

I don't know why—maybe it's the knowledge that the consumer is knowingly swallowing liquified vegetables —but this works 100 percent of the time.

11. Learn about sports. People are less likely to notice that you're on your fifth slice of pizza if you can contribute to the conversation.

12. Share fitness-related posts on social media.

Re-share an at-home workout video every now and then. Someone somewhere is bound to use it.
