On day 1, lunch is 3 cups of spinach topped with 3 ounces of salmon or sardines; the greens are loaded with vitamins A and K, plus iron, while the fish supplies protein and omega-3 fats. Include some chopped veggies on your salad, like tomato, broccoli and bell pepper for fiber and vitamin C to help you absorb the iron. Have a salad again on day 5, but use romaine lettuce this time, and substitute cannellini beans for your protein and choose cucumber, carrots and asparagus tips as veggies. Opt for olive oil and red wine or balsamic vinegar for your dressing.
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.
