Type 2 Diabetes Remission: What the 54% Result Means

You are 38. Your doctor has just told you that your HbA1c came back at 7.4% and you now have type 2 diabetes. You leave with a metformin prescription and a sense that this is for life.

A new trial suggests that for people diagnosed young, the story can go differently. In a study presented at the European Association for the Study of Diabetes (EASD) meeting, 54% of adults under 45 reached type 2 diabetes remission within six months on a low-calorie diet plus exercise. Only about 4% of a comparison group on usual care did.

That headline needs careful reading. Here is what the trial tested, what "remission" really means, why acting early matters, and who should never try this without a medical team.

What the RESET for Remission Trial Actually Tested

RESET for Remission ran across three centres: the University of Leicester in England, McGill University in Montreal and the University of Alberta in Edmonton. Professor Kaberi Dasgupta of McGill and Professor Thomas Yates of Leicester led it, and the results were published in The Lancet Regional Health Americas.

According to the summary released through ScienceDaily, the trial enrolled 96 adults aged 18 to 45 who had type 2 diabetes and obesity and were not using insulin. Their average age was 38 and their average BMI was 35.2.

The two groups

• Intensive group (50 people): 800 to 900 calories a day for 12 weeks, split roughly 30% protein, 50% carbohydrate and 20% fat. Meal replacements only for two weeks, then one normal meal a day. Supervised exercise twice a week, plus one session alone.
• Weeks 13 to 24: holding the weight off.
• Usual care group (46 people): carried on with their normal medical treatment.

In the intensive group, diabetes medications were stopped at the start, under supervision.

The results, with the numbers attached

At 24 weeks, 27 of 50 people in the intensive group were in remission. In the usual care group, 2 of 46 were. After statistical adjustment, the intensive group was about 21 times more likely to reach remission.

Average weight in the intensive group fell from 100.7 kg to 92.3 kg, a loss of 8.4 kg. The usual care group lost 1.2 kg. Adjusted for other factors, the gap was 7.5 kg, and 6.6 kg of that was fat.

The diet was not easy: 43 of the 50 reported at least one side effect, mostly early constipation, headache, dizziness or fatigue. None were severe.

What Type 2 Diabetes Remission Means (and What It Does Not)

In RESET for Remission, it meant an HbA1c below 6.5% (48 mmol/mol) at 24 weeks, with no glucose-lowering medication for at least 12 weeks. HbA1c is a blood test that reflects your average blood sugar over the past two to three months.

The NHS-backed patient site Know Diabetes describes remission as an HbA1c below 48 mmol/mol on two occasions at least six months apart while off all diabetes medicines. The NHS programme uses two readings at least three months apart. So a six-month result is an early signal, not the finish line.

Why "remission" is not "cure"

The trial summary itself says remission "does not necessarily mean the disease has been permanently cured." If weight creeps back, blood sugar usually follows.

In DiRECT, the best-known remission trial, remission held at two years in a little over a third of the intervention group, down from 46% at one year. Those who stayed in remission were mostly those who kept the weight off.

So treat remission as a state you maintain, with yearly checks of HbA1c, eyes, feet and kidneys.

Why Early-Onset Diabetes Is a Different Disease

Type 2 diabetes diagnosed before 45 tends to behave more aggressively than the same diagnosis at 65. Reviews of young-onset disease describe a faster decline in the insulin-producing beta cells of the pancreas and earlier complications.

The starkest data comes from teens. In the NIH-funded TODAY study, which followed 500 people diagnosed as youths, 60% had at least one diabetes-related complication within 15 years, at an average age of 26. They were diagnosed younger than the RESET group, but the pattern points the same way.

The math of time

Diagnosed at 38, you could live with diabetes for 40 years or more, and every year of high blood sugar adds damage to small vessels in the eyes, kidneys and nerves. There is also a biological window. Remission depends on beta cells that still work once fat is cleared from the liver and pancreas. The longer diabetes runs, the fewer working beta cells you have left, which is why most remission programmes target people diagnosed in the past few years. The NHS programme, for example, only takes people diagnosed within the last six years.

What the Big Remission Trials Found

DiRECT: the trial that started it

DiRECT, published in The Lancet, ran in UK GP practices. Participants stopped diabetes and blood pressure drugs and lived on a formula diet of 825 to 853 calories a day for three to five months. Food was then reintroduced step by step.

• 46% of the intervention group (68 of 149) were in remission at 12 months, versus 4% of controls.
• Among those who lost 15 kg or more, 86% were in remission.
• Among those who lost 10 to 15 kg, the figure was 57%.

Remission tracks the amount of weight lost, not the brand of shake or the specific foods.

The NHS Type 2 Path to Remission programme

NHS England turned DiRECT into a 12-month service that starts with 12 weeks of total diet replacement (soups and shakes), followed by food reintroduction and maintenance support.

An evaluation in The Lancet Diabetes & Endocrinology found that among programme completers with two HbA1c readings, 145 of 450 (32%) were in remission at one year. The authors noted that was lower than in controlled trials.

Your Weight-Loss Target: A Worked Example

Say you are 40, weigh 95 kg and burn roughly 2,400 calories a day. That burn rate is an assumption for illustration; yours depends on height, sex and activity.

Step 1: Set the target

DiRECT's data gives two useful marks. A 10 kg loss takes you to 85 kg, about 10.5% of your starting weight. A 15 kg loss takes you to 80 kg, about 15.8%. In DiRECT, those bands came with remission rates of 57% and 86%.

Step 2: Work out the daily deficit

On an 850 calorie plan, your daily gap is 2,400 minus 850, or 1,550 calories. A common rule of thumb puts a kilogram of body fat at about 7,700 calories.

• 10 kg x 7,700 = 77,000 calories. At 1,550 a day, that is about 50 days, or 7 weeks.
• 15 kg x 7,700 = 115,500 calories. At 1,550 a day, that is about 75 days, or 11 weeks.

Step 3: Adjust for real life

That is the best case. Your body burns less as you shrink, and people slip. The RESET group lost 8.4 kg in 24 weeks on average, well under what the formula predicts.

A realistic plan is a 12-week low-calorie phase aiming for 10 to 15 kg, then long maintenance. If you want to keep muscle while you lose, protein and lifting matter; our guide on how much protein you need each day covers the targets.

What a Low-Calorie Phase Looks Like Day to Day

A typical early day, based on the RESET and NHS formats:

1. Breakfast: one meal-replacement shake.
2. Lunch: a soup or bar from the same product range.
3. Dinner: another shake or soup. In RESET, from week 3 this became one normal meal with protein, fruit and vegetable targets.
4. Fluids: at least 2 litres of calorie-free drinks a day, as RESET advised.
5. Movement: RESET used aerobic and resistance sessions, three a week in total.

Hunger usually peaks in week one, then eases. The hardest stretch is often the reintroduction, when normal food and old portion sizes creep back.

Exercise may help protect muscle, though the researchers said that needs a longer study. See our piece on strength training and the weekly sweet spot.

Who Should Not Try This Without Medical Supervision

Cutting to 800 calories on certain diabetes drugs can be dangerous.

• Insulin: doses that suited your old diet can drive blood sugar too low once you eat far less. RESET excluded insulin users entirely.
• Sulfonylureas (such as gliclazide): these push the pancreas to release insulin regardless of what you eat, raising the risk of hypoglycaemia.
• SGLT2 inhibitors (drug names ending in "gliflozin"): Know Diabetes flags these alongside insulin and sulfonylureas as needing a talk with your health team first.

Anyone pregnant, with a history of eating disorders, or with serious kidney or heart disease should also see a doctor first. In the major trials, clinicians made the medication changes on day one, not participants.

Weight-loss drugs are another route; our breakdown of what GLP-1 drugs actually cost each month covers the numbers.

What This Study Does Not Show

Randomisation means the gap between groups reflects the programme. The limits are still real.

• It was small. 96 people, and 10% did not complete final assessments.
• It was short. Six months says nothing yet about two or five years.
• It was open-label. Participants and staff knew who was in which group.
• It was heavily supported. Supervised exercise and close follow-up are hard to copy at home.

Frequently Asked Questions

Can type 2 diabetes go into remission?

Yes, for many people. In DiRECT and RESET for Remission, large weight loss brought HbA1c below 6.5% without medication. It works best soon after diagnosis and lasts only while the weight stays off.

How much weight do you need to lose to reverse type 2 diabetes?

There is no single number, but in DiRECT, 57% of people who lost 10 to 15 kg and 86% of those who lost 15 kg or more were in remission at one year.

Is an 800 calorie diet safe for diabetics?

It can be when supervised. If you take insulin or sulfonylureas, blood sugar can fall too low, so your doctor needs to adjust your medication before you start.

Can type 2 diabetes come back after remission?

Yes. Remission is not a cure, and regaining weight is the most common reason blood sugar rises again. In DiRECT, the share in remission fell from 46% at one year to a little over a third at two years.

The Bottom Line

If you were diagnosed young, RESET for Remission argues for acting in the first few years. Losing 10 to 15 kg through a supervised low-calorie phase gives many people a real shot at type 2 diabetes remission.

Bring these numbers to your next appointment and ask about your medications and any structured programme near you. The diet gets you into remission; keeping the weight off is what keeps you there.
