Yes, I have been using my Vitamix again. This time I counted the calories, so I could have a treat on the fast days of my 5:2 Diet.

I added a bit of fizz to my smoothie with some white grape Shloer (a non-alcoholic fizzy drink), but you could add some apple juice instead. If you really wanted a spot of luxury, you could turn this into a cocktail by replacing the Shloer with champagne.

Whichever way you make this smoothie, you are sure to enjoy it and benefit from adding extra portions of fruit and veg into your day.

If you aren't lucky enough to have a Vitamix, juice the carrot before adding it. Alternatively you could chop the carrot finely, grate it, or steam and mash it before adding it to your blender.

Looks pretty appetising doesn't it? Dr Michael Mosley. Photo courtesy of BBC2 Horizon This was my dinner last night. Yesterda...
