My experience with intermittent fasting finds that’s it’s best to start with a 16 hour fast (i.e. 8PM one evening to 12PM the next day) for the first 1-2 weeks. Once you are comfortable with this schedule, you can increase the amount of time you spend fasting. Do this by adding 30 minutes to each fast until you get to where you are fasting for 20 hours at a time.
Soft drinks, fruit juice, muffins, white rice and white bread are technically low in fat, for example, but the low-fat group was told to avoid those things and eat foods like brown rice, barley, steel-cut oats, lentils, lean meats, low-fat dairy products, quinoa, fresh fruit and legumes. The low-carb group was trained to choose nutritious foods like olive oil, salmon, avocados, hard cheeses, vegetables, nut butters, nuts and seeds, and grass-fed and pasture-raised animal foods.
