PPT diet describes a personalised postprandial-targeting diet. PPT diet can’t be generalised as it doesn’t include a set of guidelines to follow, unlike other diets. This diet’s effectiveness relies on its personalisation to the individual.

PPT diet relies on a machine learning algorithm.

This algorithm combines clinical and microbiome features to predict personal postprandial glucose responses.

Glucose response is a term describing the levels your blood sugar reaches after you eat.

After a meal, the food digestion process begins in your stomach.

Then enzymes in your body break down the components of your food into smaller building blocks. 

Carbohydrates in your food are broken down into glucose.

The study found that the people who followed the PPT diet experienced greater reductions in the time that their daily glucose levels were over normal levels.

This means that the PPT diet improved glycemic control “significantly more” than the Mediterranean diet. 

The study looked at 225 adults with prediabetes who followed either a Mediterranean diet or a PPT diet for six months.

The researchers also did an additional six-month follow-up.

All participants had to use continuous glucose monitors for the duration of the study and the follow-up.

Even though the Mediterranean diet also reduced the levels, the PPT diet reduction results were “significantly greater” even during the follow-up.

Prediabetes describes people whose blood sugar levels are above the normal range, but not high enough to be classified as diabetes.

This research suggests that following a more personalised diet could bring better results at managing blood sugar spikes after meals for people with prediabetes.

However, these findings don’t contradict the effectiveness of the Mediterranean diet either.

Mediterranean diet is mainly plant-based including foods like vegetables, beans, pulses, nuts and olive oil.

This type of diet can help improve blood glucose management in people with type 2 diabetes, according to Diabetes UK.

Some of the main symptoms of diabetes to spot include:

• Feeling very thirsty
• Peeing more frequently than usual
• Itching around the penis or vagina
• Cuts and wounds healing slowly
• Having a blurred vision.

The NHS advises visiting your GP as soon as possible if you experience any of these.
