The Pioppi diet, when compared to the UK government guidelines, it shares a similarity to it. They both recommend eating plenty of fruits and vegetables, keeping the consumption of red meat to an average of 500g per week, and encourages a healthy lifestyle overall. However, the recommendations for total fat goes against NHS reference intakes.

The Pioppi diet should not be done by the elderly, those under 18 years of age, those undergoing medication, have low BMIs, those who have emotional or psychological issues with food, and especially by those who are pregnant, breastfeeding, or diabetic.

The Pioppi Diet does allow one to consume less food and calories. When we consume less calories the we will eventually lose weight, most especially when one decides to start incorporating an active lifestyle alongside the diet.

However, this is still dependent on your starting weight and existing diet and lifestyle.

Regarding its sustainability, it is debatable. For the Pioppi Diet to be done for more than 21-days is hard to maintain since it omits a whole food group.
