5-2-Diet Book Review and OverviewAbout the Diet

The 5:2 diet is a plan the involves intermittent fasting (IF). If you have any issues with blood sugar, or a lifestyle or occupation that requires daily energy from food, this is probably not the best plan for you. If you are pregnant or nursing, this is not a good plan to consider.*

On two, non-consecutive days each week you will severely restrict your calories, on the other five days you eat normally. As is the case with many diets, dramatically reducing caloric intake can cause headaches, fatigue, mood swings, and mental confusion — and problems with low blood sugar for some people. On fasting days men are only permitted to eat up to 600 calories, and women can only eat 500 calories. That’s not a lot of food.

Proponents of the 5:2 say that fasting for only two days a week may be easier for dieters to comply with than daily calorie restriction. The problem is that the entire diet relies on your ability to adhere to the fasting requirements and if you don’t — you blow the entire week.

This diet became popular in the UK in 2012, and is still has a strong, loyal following, but this diet, also coined the “fast diet” is extreme, so please consult your doctor before you try this diet as fasting — even partial fasting — may be unsafe for certain individuals. For example, fasting and rapid weight loss can cause or exacerbate gallstones:

  • Rapid weight loss. As the body metabolizes fat during rapid weight loss, it causes the liver to secrete extra cholesterol into bile, which can cause gallstones.
  • Fasting. Fasting decreases gallbladder movement, which causes the bile to become over-concentrated with cholesterol.
