Preheat an electric grill on high. Grease the grill grates with two tablespoons of oil.
Rinse the meat under cold running water and pat dry with a kitchen towel. Place on a clean work surface and slice into half-inch thick slices. Rub each slice first with oil and then with lemon juice. Season with salt and pepper.
Using long tongs, place chicken breast on the preheated grill. Grill for 4 minutes, or until lightly charred. Flip and grease with some more oil. Continue to cook for 3-4 minutes.
Serve immediately with a low carb salad or leafy greens and your favorite low carb sauce/dip.
Notes
*To increase fat, you can use chicken thigh or chicken breast with skin on. You can serve with a few avocado slices or fatty sauce such as mayonnaise.
