Recent studies have also shown that garlic supports blood-sugar metabolism, and helps control lipid levels in the blood. What’s more? Eating garlic can help boost your immune system, help ward off heart disease, fight inflammation, increase memory retention, and lower blood pressure, so consider adding some to your next meal. At the very least, it is preferable over salt, which can lead to water weight gain and bloating.
Forget old low-carb diet plans that focused on processed protein bars and shakes. This year, the keto diet got high marks for low carb. Keto, short for "ketogenic," is all about training the body to burn fat for fuel. How? By eating fat—and lots of it. Most keto diets recommend getting at least 70 percent of your daily calories from fat and the rest from protein. The goal is to eat as few carbohydrates as possible. Proponents say it helps them drop weight fast with little or no hunger in addition to perks like more energy and mental clarity. (Interested? Here's everything you need to know about the keto diet.)
Finally, people eat about nine servings of fruits and vegetables a day on a Mediterranean diet. (1) Produce packs an array of disease-fighting antioxidants, and people who fill their diet with these foods have lower risk of disease. Yet as the National Institutes of Health points out, it’s not known if it’s the antioxidants or other compounds (or general healthy eating patterns) that are responsible for these advantages. (5)
At the end of this 12 week study, scientists observed similar loss in body fat and overall body weight in all three diets. However, they noted that the VLCARB ketogenic diet was “more effective in improving tracylglycerols, HDL cholesterol, fasting and post-meal glucose and insulin concentrations. More specifically, triacylglycerols decreased by 39.9% in VLCARB subjects, 4.0% in VLF subjects, and 9.6% in HUF subjects. 
A ketogenic diet helps control blood sugar levels. It is excellent for managing type 2 diabetes, sometimes even leading to complete reversal of the disease. This has been proven in studies. It makes perfect sense since keto lowers blood-sugar levels, reduces the need of medications and reduces the potentially negative impact of high insulin levels.
