Intermittent Fasting: For the majority of individuals, fasting all day and then having a good evening meal is the best strategy for a fast day. A small calorie allowance on fast times is of 500-600 calories. A single 500 calorie meal can be very substantial, but you may be able to possess mini-meals if you try to spread the calories more than dinner, lunch and breakfast.
Most men and women find that eating just a small amount only cures the hunger pangs for a brief time and actually makes them hungrier for the rest of the day, therefore it is generally best to avoid snacking on fast days and spare your calories until you can have a full healthy meal.
In addition to being easier for many people, waiting to eat before is also more effective for weight loss, as you will have fasted for longer. A survey inquired into the factors that influence weight loss on the 5:2 diet has proven this. The analysis of our survey questionnaire discovered that fasting for over 20 hours on a fast day led to a greater weight loss than fasting for less than 16 hours. There are lots of possible scientific explanations for why this could be. Dr. Jimenez discusses the topic at length.
