That said, Atkins is on this list for a reason. When you follow Atkins, you’re not necessarily eating in a well-rounded way. That’s because Atkins teaches consumers to restrict certain carbs to lose weight. In truth, restricting entire food groups can come with health risks.

According to the Mayo Clinic, “it's…possible that restricting carbohydrates to less than 20 grams a day -- the level recommended for phase 1 of the diet -- can result in ketosis. Ketosis occurs when you don't have enough sugar (glucose) for energy, so your body breaks down stored fat, causing ketones to build up in your body. Side effects from ketosis can include nausea, headache, mental fatigue and bad breath.”

So don’t rule out this plan altogether. But steer clear of Atkins if you have kidney issues.

The Baby Food Diet

Celebrities swear by The Baby Food Diet. In fact, Reese Witherspoon, Lady Gaga and Jennifer Anniston are said to have tried it.

According to Shape magazine, “The diet reportedly involves replacing breakfast and lunch with about 14 jars of baby food (about 25 to 75 calories each), and then eating a sensible dinner.”

The problem is that this diet is nearly impossible to stick with. Really, who wants to eat baby food? There’s a reason it’s made for infants. Pureed mixtures of foods that just don’t go together are anything but satisfying. That’s why we say this diet is a no-go.
