Intermittent Fasting and the Wheyless Program

I have been approached several times by people trying to decide on a weight loss strategy who had seen Dr Michael Mosley’s television show on intermittent fasting and the incorporation of the 5:2 Diet (see

 They wanted to know how this approach compared to the Wheyless program.

For those of you who are not familiar with the 5:2 diet, it consists of fasting on two non-consecutive days each week, allowing only 500-600 calories on each of those days, split between breakfast and dinner. On the other 5 days you can eat what you like and as much as you like. 

By fasting in this way the body thinks it is going into a famine situation and energy is not expended on growth and reproduction. Instead a number of repair genes are switched on and the body goes in for a service, focusing on repair, healing and weight loss.  This is an ideal situation that is reflected in positive changes in fasting glucose, triglycerides, HDL and LDL cholesterol and many of the body’s important hormones such as IGF-1 (insulin-like growth factor). 

It’s easy to use the intermittent fasting model in conjunction with the Wheyless program. The only two changes that I would recommend are:

  1. Just consume two Wheyless shakes on each of the two fasting days with the addition of 1/2 punnet of berries and a salad with leafy greens, fresh herbs and 4-5 olives.
  2. During the 5 free-food days continue with one or two Wheyless shakes plus two meals from the suggested recipes on this website It is really important to continue to feed the body nutritious foods rather than mindlessly reverting back to junk food habits.
