5:2 The Fasting Diet

The diet has risen in popularity over recent years due to its simplicity and coverage in various documentaries and studies.

So what is the 5:2 diet?

Based on the principle know as intermittent fasting (IF) where you eat normally at certain times and fast during the others, the plan is quite simple. You eat normally for 5 days of the week and fast on the remaining two.
This works by cutting your calorie intake for those 2 days to a 1/4 of their normal level. It is suggested to have between 500-600 calories if you are female or 600-700 if you are male.  The success of this diet relies on not over eating during your normal eating days.
Although is simple and effective, this type of diet does not produce the best weight loss results due to it intermittent nature. So if you are looking for faster weight loss it is recommended that you look at the other Low Calorie Diet plans.

I was very surprised at how nice the range is. The soups and noddles are filling and keep me full up until the next one. Only been on the shake that weight diet a few days but can see it working if I don’t cheat. *

I am now 2 weeks in, and being very strict with it. I am not finding it very difficult to stick to. On Fathers day my husband wanted a Chinese meal out, I went, ordered what I usually eat and left most of it, I did not like the taste, and would have rather had a shake! I have lost 4 KG in 2 weeks and going strong, I have just reordered the shakes as they are what works well for me. This is an incredibly easy to stick to diet. *

No. But light exercise like 30 mins of walking a day is advised
