The keto diet - a high-fat, moderate-protein, and low-carb eating approach - helps with weight loss and lower blood sugar.

The diet calls for consuming high amounts of fat, a moderate amount of protein, and a very limited amount of carbs. It's usually broken down to 75, 20, and 5 percent of your daily calories. Compare that with the typical American diet - which is usually 50 to 65 percent carbs - and it's safe to say this is a completely different way of eating.

After you follow the diet for a few days, your body enters ketosis, which means it has started to use fat for energy. Newbies on the diet find it helpful to track whether they're in ketosis with a urine ketone strip or a blood-prick meter, but you'll eventually learn what ketosis feels like and will know whether you're in it.

Here are some of the foods you may eat on keto:

• Oils (like olive oil, avocado oil, and coconut oil)
• Avocado
• Coconut (unsweetened)
• Nuts (almonds, macadamia) and seeds (chia seeds, flaxseed, sunflower seeds)
• Leafy green vegetables (romaine, spinach, kale, collards)
• Nonstarchy vegetables, including zucchini, asparagus, cucumber, broccoli, cauliflower, and bell peppers.
