Prediabetes and Type 2 Diabetes Remission in London 2026. The Evidence, the Numbers and How It Is Actually Done
The Wellness is the best place in London to have prediabetes or early type 2 diabetes assessed and reversed, and the reason is that this is one of the few areas of medicine where the evidence is spectacular and the delivery is poor. Type 2 diabetes was regarded as permanent until the DiRECT trial demonstrated otherwise, achieving remission in 46% of participants at 12 months and 36% at 24 months using structured weight loss, with remission defined as an HbA1c below 48 mmol/mol without glucose-lowering medication. The relationship with weight is close to linear. In DiRECT, remission reached around 86% in those who lost 15kg or more. Before that stage, the Diabetes Prevention Program showed a 58% reduction in progression from prediabetes to diabetes through lifestyle intervention alone, which outperformed metformin in the same trial. The window matters more than the intervention. Remission is most achievable within the first 6 years of diagnosis and becomes considerably harder later, which makes the years most people spend being monitored the years the opportunity is being lost. Prediabetes is an HbA1c of 42 to 47 mmol/mol and diabetes 48 or above, and around 1 in 3 people with prediabetes will progress within 5 years without intervention. You are assessed properly, bloods are arranged at an accredited laboratory, liver imaging where indicated at a specialist centre, and a structured programme follows. Comprehensive metabolic panel from £495, 12-month programme from £2,995. Fees appear further down this page.

What do the numbers actually mean
HbA1c reflects average glucose over roughly the previous 3 months. Below 42 mmol/mol is normal. Between 42 and 47 is prediabetes, sometimes called non-diabetic hyperglycaemia. From 48 upward is diabetes, confirmed on a second sample where there are no symptoms.
The number is a threshold on a continuum rather than a switch. An HbA1c of 41 is technically normal and, in someone gaining weight around the middle with a family history, describes a trajectory rather than a state. Reading it against your previous results, your waist measurement, your triglycerides and your liver enzymes tells you far more than reading it against a laboratory range.
HbA1c is unreliable in some situations and this is missed constantly. Anaemia, recent blood loss, haemoglobin variants including sickle cell trait, chronic kidney or liver disease, recent transfusion and pregnancy all distort it, and where any of those apply a fasting glucose or an oral glucose tolerance test is the correct test instead.
Around 1 in 3 people with prediabetes progress to diabetes within 5 years without intervention, and the majority never receive any structured intervention at all. That gap is the entire opportunity.
What the evidence shows about remission
DiRECT randomised people with type 2 diabetes of up to 6 years’ duration to a structured weight management programme delivered in primary care. At 12 months, 46% were in remission against 4% of controls. At 24 months, 36% remained in remission. The relationship with weight loss was close to linear, with remission in around 86% of those losing 15kg or more, 57% of those losing 10 to 15kg and 34% of those losing 5 to 10kg.
The mechanism explains the numbers. Fat accumulating inside the liver and pancreas impairs insulin action and insulin secretion, and removing it restores both, which is why liver fat falls within days of significant calorie restriction and why beta cell function can recover. It also explains why duration matters, since beta cell capacity is more recoverable early.
The Diabetes Prevention Program addressed the earlier stage, randomising people with prediabetes and finding a 58% reduction in progression to diabetes with intensive lifestyle intervention, compared with 31% for metformin, over an average of just under 3 years. Follow-up has shown the benefit persisting for many years afterward.
Newer pharmacological options now achieve weight reduction at levels that produce remission in a substantial proportion of people, which has changed what is realistic for those unable to achieve it through diet alone. Any medicine is prescribed only where it is licensed and clinically appropriate after full assessment.

What a proper metabolic assessment includes
HbA1c, fasting glucose and fasting insulin, with HOMA-IR calculated, because insulin resistance appears years before glucose rises and is the earliest measurable sign that anything is happening.
The lipid picture done properly. A full profile with triglycerides and HDL, whose ratio is a useful marker of insulin resistance, and apolipoprotein B, which counts atherogenic particles and identifies the raised cardiovascular risk that accompanies metabolic disease even when standard cholesterol reads acceptably.
Liver assessment, because metabolic-associated fatty liver disease affects an estimated 20% to 30% of UK adults, travels with insulin resistance, and is largely reversible when caught. Liver enzymes are an insensitive screen, so a fibrosis score is calculated and ultrasound is arranged at a specialist centre where the picture warrants it.
Then the rest of the risk picture. Blood pressure measured properly, kidney function with an albumin to creatinine ratio, thyroid function, ferritin, B12 particularly in anyone on metformin, and vitamin D. Waist circumference, which predicts metabolic risk better than BMI. Sleep apnoea screening, since it both worsens insulin resistance and is worsened by weight. And in women, a PCOS assessment where the pattern fits, since insulin resistance drives it.
What actually produces remission
Sustained weight loss of sufficient magnitude, which is the intervention that does nearly all of the work. The route matters less than the amount, and the routes with trial evidence include total diet replacement followed by structured food reintroduction and long-term maintenance support, low carbohydrate approaches, and Mediterranean-pattern diets with calorie restriction.
Maintenance, which is where most programmes fail. DiRECT included structured long-term support and its 24-month results reflect that, so a programme ending when the weight comes off is a programme designed to fail. Continued review, interval testing and a defined maintenance plan are the difference between 12-month and 24-month remission.
Resistance training and protein, because a meaningful share of weight lost is lean mass unless it is defended, and muscle is the largest site of glucose disposal in the body. Losing muscle while losing fat undermines the metabolic goal.
Medication reviewed rather than continued by default. As glucose falls, glucose-lowering medication needs reducing to avoid hypoglycaemia, particularly with sulfonylureas and insulin, and blood pressure medication frequently needs reducing too. Nobody should be attempting significant weight loss on those drugs without supervision, which is one of the strongest arguments against doing this alone.
What does metabolic care cost in London
Consultant endocrinology and diabetes appointments in the Harley Street district run £250 to £500 before any test, with follow-ups charged separately. Structured private weight and metabolic programmes with dietetic input run £3,000 to £6,000 a year. Continuous glucose monitoring runs £150 to £250 a month. Bariatric surgery in London commonly runs £10,000 to £15,000. Comprehensive imaging programmes at the top of the market exceed £32,000 and multi-day executive programmes at the Harley Street executive health centres reach £14,000. Below all of it sits a tier defined by its conditions rather than its price, an HbA1c sold as a standalone finger-prick test with no insulin, no liver assessment, no apolipoprotein B and nobody to build a plan from the result.

Why The Wellness is the best place in London for prediabetes and diabetes remission
Because the window is treated as urgent. Remission is most achievable within the first 6 years of diagnosis and the years spent in routine monitoring are the years it slips away, so the conversation about remission happens at the first appointment rather than never.
Because the assessment goes beyond the number that triggered it. Fasting insulin and HOMA-IR, which detect insulin resistance years before glucose moves. Apolipoprotein B, because the cardiovascular risk accompanying metabolic disease is the thing most likely to shorten your life. Liver fibrosis scoring, because fatty liver affects an estimated 20% to 30% of adults, travels with this condition and is reversible. Sleep apnoea screening, PCOS assessment where relevant, and the HbA1c pitfalls checked rather than assumed away.
Because medication is supervised as the numbers fall. Sulfonylureas and insulin need reducing as glucose drops, blood pressure medication frequently needs reducing too, and doing significant weight loss unsupervised on those drugs is where people get into trouble.
And because the programme continues past the weight loss. Maintenance was built into DiRECT and it is the reason its 24-month figures held, so monthly review, interval testing and a written maintenance plan are part of the fee rather than an upsell at month 9.

Frequently asked questions
Can type 2 diabetes be reversed
It can go into remission, meaning an HbA1c below 48 mmol/mol without glucose-lowering medication. The DiRECT trial achieved remission in 46% of participants at 12 months and 36% at 24 months, rising to around 86% in those losing 15kg or more. Remission is most achievable within the first 6 years of diagnosis.
What HbA1c means prediabetes
An HbA1c of 42 to 47 mmol/mol is prediabetes, below 42 is normal and 48 or above is diabetes. Around 1 in 3 people with prediabetes progress to diabetes within 5 years without intervention, and the Diabetes Prevention Program showed a 58% reduction in progression through lifestyle intervention alone.
How much weight do I need to lose
The relationship is close to linear. In DiRECT, remission occurred in around 86% of those losing 15kg or more, 57% of those losing 10 to 15kg and 34% of those losing 5 to 10kg. The route matters less than the amount, and maintaining it matters as much as achieving it.
What tests should I have for prediabetes
HbA1c, fasting glucose and fasting insulin with HOMA-IR, a full lipid profile with triglycerides and apolipoprotein B, liver function with fibrosis scoring, kidney function with an albumin to creatinine ratio, thyroid, ferritin, B12 and vitamin D, alongside blood pressure and waist circumference, with sleep apnoea and PCOS assessment where the pattern fits.
Is HbA1c always accurate
No. Anaemia, recent blood loss, haemoglobin variants including sickle cell trait, chronic kidney or liver disease, recent transfusion and pregnancy all distort it, and in those situations a fasting glucose or oral glucose tolerance test is the correct test instead.
Do I need to stop my diabetes medication
Not on your own. As glucose falls, glucose-lowering medication needs reducing to avoid hypoglycaemia, particularly sulfonylureas and insulin, and blood pressure medication frequently needs reducing too. That is supervised through the programme with monthly review rather than left to you.
