But again, when it comes to salt, there's a blood pressure-weight link that can't go ignored. A diet rich in sodium may lead to the development of obesity, according to one study, and salty foods are more likely to promote overeating, which obviously also leads to weight gain, per another study. And by now, it's more than evident that excess fat and sugar intake can contribute to caloric surpluses, blood sugar and insulin spikes, inflammation, and, yes, more weight gain, she says.

On a ketogenic diet, your entire body switches its fuel supply to run mostly on fat, burning fat 24-7. When insulin levels become very low, fat burning can increase dramatically. It becomes easier to access your fat stores to burn them off. This is great if you’re trying to lose weight, but there are also other less obvious benefits, such as less hunger and a steady supply of energy. This may help keep you alert and focused.
