If you've ever scrolled through social media, you know how crazy diet trends can be.

One week bacon is good for you, the next week it's off-limits. One month carbs are evil, the next month people remember that we need them to live. One year....eh, you get my gist.

To clear up the confusion, I spoke with Rachel Soderquist, a Registered Dietitian at Del Sol Community Wellness about the recent diet trends that I've seen popping up on my online feeds.

We started with the ketogenic diet, more commonly known as 'keto.' This diet a low-carb, high-fat eating plan that is designed to push your body into ketosis, or a "starvation state."

Unsurprisingly, this diet is an effective way to lose weight, but it is not meant to be sustainable.

"It's pretty extreme, so the chances of being able to follow this diet for a long time are slim," said Soderquist. "We also don't have many studies that show the effects of what happens when you're in ketosis for a long time...it's hard to say whether or not it's safe in the long-term."

However, in the short term, the keto diet is generally safe for those who do not have other health issues, and are working closely with a dietitian or doctor.

Fasting, on the other hand, can be done in a variety of ways.

Some people choose to not eat two days out of the week, and then eat whatever they want for the other five days. Others choose to fast everyday, but only for a certain period of time.

Again, there is limited research on the effects of fasting, as most of the studies have been conducted on animals.

"It does mess with your metabolism again, pushing it into the starvation state," said Soderquist.

In her opinion, the best method of dieting is to choose something practical that you can sustain for a long time.

She recommends consuming everything in moderation, so that you can have the occasional glass of wine without feeling guilty...although, increasing your fruit and veggie intake never hurts.

Overall, the most important thing is to do your research and listen to your body.

"Don't listen to everything you see on social media," said Soderquist. "Everyone's metabolism is different and you need to find what works for you...not just what you're favorite Instagram star is doing."
