The 16:8 method of intermittent fasting is sometimes also referred to as 18:6 fasting or time-restricted fasting. With this type of intermittent fasting, your food intake will be restricted to an eight-hour window, followed by a total fast for 16 or 18 hours.
This method of intermittent fasting can be a good option for helping to maintain your weight after completing a weight loss programme.
What you can eat during intermittent fasting depends on the specific diet plan you’re following. For example, the Eat Stop
Eat diet plan allows you to continue eating the same foods that you usually do, whereas the 16:8 and 5:2 diet plans encourage you to reduce your daily calorie intake, focusing on lean protein and non-starchy fruit and veg. You might also choose to support your intermittent fasting plan with OPTIFAST meal replacement products
Everyone has different goals, which means everyone’s results will be different. You may find that you notice a difference in the way that you feel within the first week of changing your eating habits, but some people may not notice a change until they see a new number on the scales. Speak to a healthcare professional if you want support setting a realistic weight loss goal tailored to your individual needs.
Intermittent fasting can be a long-term healthy lifestyle change; some people like to continue with intermittent fasting after achieving their weight loss goals to help them to maintain their weight. Everyone’s goals are different, so you may just want to try intermittent fasting for a shorter period, before trying another diet plan, such as Partial Meal Replacement.
Always seek medical advice before undertaking a major change in your diet or lifestyle, particularly if you take medication or have a medical condition.
