Low carb, high protein. Keto this, keto that. Sure, it might help you lose a few quick pounds, but that doesn't mean its healthy or sustainable.

Our bodies run on glucose and break down carbs for energy and muscle protection. We have a reliance on them for good reason and when you take that away, sure you might lose some weight, but you're putting yourself at risk for muscle loss, fatigue, constipation...not pretty. Plus, who really wants to not eat carbs? Low carb diets are just that, diets. Fads.

They're not sustainable, and you're going to eventually go back to eating them or incorporating at least lower amounts.

So the results are temporary.

Your body has a tolerance for carbs, but when you reintroduce after going cold turkey it's very probable you'll gain all the weight back and then some because you've caused an imbalance in that tolerance. Plus, a lack of clean carbohydrates and whole foods including fruits and vegetables means depriving your body of a whole lot of nutrition and nourishment.

Nutrition Solutions puts it plainly: "Your body can only exist in a restricted deficit for so long, and when, not if, you introduce carbs back in your diet, your body basically freaks out and goes into fat/water storing mode in a valiant effort to super overcompensate for the hell you’ve put it through."

Just because they help you lose weight, doesn't mean they're healthy by any means. Don't tell me that greasy, fatty bacon and buttered up steak is better for you than some pasta, veggies, potatoes, and fruits. Many people doing these diets aren't even incorporating healthy proteins like certain vegetables, but are instead using taking advantage of eating as much meat as they can.

Maybe you're losing some weight, but that doesn't mean your arteries aren't clogging and your cholesterol isn't high.

Being thin or "in shape" doesn't always reflect whats on the inside.

Diets high in protein are also related to heart disease. Samantha Heller is a clinical nutritionist at New York University's medical center and says while these diets are attractive because of a quick pound shed and allow people to eat as much bacon and steak as they like, they pose a lot of risks.

Heller says diet's high in animal protein are linked to increased risks of colon cancer, diabetes and heart disease:

"Research suggests that the connections between a high intake of animal foods and health may be related to how the meats are processed, how we cook them and how our bodies use them."

So before you refuse to eat a slice of bread, rice or some high carb fruit, think about what that bacon wrapped chicken is really doing for you.
