Which one will top the value for money leader board?

Lisa Riley's Honesty Diet is road-tested £ for lb by 44-year-old surgical matron Clare. Will this diet based on fresh food, no white carbs, alcohol or snacking make Clare's dream of the wearing the perfect wedding dress come true? And how will the diet stack up on our value for money leader board?

We also revisit Corinne, a £ for LB road test dieter from 2017 to see if she carried on her weight loss journey after trialling the Military diet. Has she carried on losing the weight or piled it back on?

WW, the newly branded Weightwatchers diet, is put to the pound for pound road test. On this plan, no food is off limits and is allocated points depending on the carbohydrate, protein and fat content. Dieters are then given a daily point limit depending on their weight. Will it work for 32-year-old IT Manager Jas? And how will the diet stack up on our value for money leader board?

This time, the Dukan Diet is road tested by 37-year-old radio presenter Matt. This diet plan is split into phases, designed to lose, stabilise and maintain weight-loss.

This week the Vegan Keto Diet is road tested by 30-year-old Holly from Kings Lynn. This diet plan combines two popular current diet plans. The Keto part is designed to put the body into ketosis where it burns fat for fuel. The Vegan element means eating only plant-based foods. Can 19-stone Holly put her years of yo-yo dieting behind her? And will this diet measure up lb for £?

This time the Scandi Diet is put through its paces by theatre director Jaydean. This Danish sensation combines four - literal - handfuls of food three times a day. One of protein, one of starch or fruit and two of veg. So no calorie counting of weighing food out at all. Can this mum of five kick her convenience food habit for good?
