One of Dr Michael’s methods is the Very Fast 800, a rapid weight loss plan slimmers can follow for up to 12 weeks by consuming just 800 calories per day.
The New 5:2 is a more gradual plan which asks dieters to limit themselves to 800 calories just two days of the week, with no calorie restrictions over the remaining five days.
The Way of Life is for those who want to maintain their already healthy weight.
All three plans follow the principle of the low carb, Mediterranean-style diet.

On Dr Michael’s website The Fast 800, the expert revealed which snacks he recommends for ultimate weight loss.
According to the expert, three meals are just enough to stay full throughout the day, and snacking is unnecessary.
The expert stated: “Snacking spikes your insulin levels between meals and tends to increase hunger.”
However, many find it difficult to resist the urge to snack between meals.
For those who get a little bit peckish during the day, Dr Michael shared four healthy, weight loss-friendly snacks, non-starchy veg, cheese, berries and nuts.
He stated: “Try to avoid snacks, especially on fasting days, but if required, have some non-starchy veg, a sliver of cheese or some berries.
“Alternatively, nuts are a great source of protein, fibre and micronutrients – just avoid salted or sweetened nuts, which can be moreish and easy to overeat.”
While berries are a great snack, Dr Michael warned that not all fruits were created equal when it comes to weight loss.
