Prediabetes Guide: What Your Numbers Mean and What Helps Most
Prediabetes means an A1C of 5.7% to 6.4% or fasting glucose of 100 to 125 mg/dL. About 115.2 million U.S. adults have it. A lifestyle program with 7% weight loss and 150 minutes of activity a week cut the chance of type 2 diabetes by 58%. No supplement, Sugar Reset included, has shown a result like that.

The basics
What is prediabetes?
Prediabetes means your blood sugar is higher than normal but not in the diabetes range. It is common, and it is a signal to act, not a diagnosis of diabetes.
CDC estimates that 115.2 million U.S. adults have prediabetes. Another 40.1 million people had diabetes in 2023, and 11.0 million of those adults did not know it (CDC, Diabetes statistics). Many people learn about prediabetes from a routine blood test.
The good news is that the steps with the best evidence are within reach. They are about movement, food and small, steady weight changes, not about any product.
Your numbers
Which A1C and fasting glucose numbers mean prediabetes?
An A1C of 5.7% to 6.4%, or fasting glucose of 100 to 125 mg/dL. Type a lab result to see its range.
| Range | A1C | Fasting plasma glucose |
|---|---|---|
| Normal | Under 5.7% | 99 mg/dL or lower |
| Prediabetes | 5.7% to 6.4% | 100 to 125 mg/dL |
| Diabetes | 6.5% or higher | 126 mg/dL or higher |
Doctors usually confirm a result with a second test (NIDDK, Diabetes tests). Our post on A1C and fasting glucose numbers explains each test in more detail.
What helps
What lowers the chance of type 2 diabetes the most?
A lifestyle program, by a wide margin. The results come from a large federal trial.
In the Diabetes Prevention Program, people with high blood sugar tried a lifestyle program, metformin or a placebo. Over about three years, the lifestyle group had the biggest drop in new type 2 diabetes (NIDDK, DPP).
58% lower chance
The goals were 7% weight loss and 150 minutes of activity a week.
71% lower chance
Older trial members did even better with the same lifestyle program.
31% lower chance
A prescription medicine. Helpful, but less than the lifestyle program in this trial.

Day to day
What does a prediabetes plan look like day to day?
A good plan is small and repeatable. The trial goals turn into everyday steps you can fit around work and family.
- Move about 30 minutes, 5 days a week. That adds up to the 150 minutes the trial used. Brisk walking counts.
- Aim for slow weight change. Seven percent of 180 pounds is about 13 pounds. Spread it over months.
- Build meals you like. A clinician or dietitian can help you plan food that fits your culture, budget and taste.
- Protect your sleep. A steady routine makes it easier to keep the other habits going.
- Recheck as advised. Your clinician will say when to repeat your A1C or fasting test.

What is the CDC National Diabetes Prevention Program?
It is a yearlong lifestyle change program recognized by the CDC. The CDC says it can cut type 2 diabetes risk in half, and it focuses on habits meant to last (CDC, National DPP).

Supplements
Can a supplement like Sugar Reset help with prediabetes?
No supplement has matched the lifestyle results, and Sugar Reset has never been tested. The ADA's 2026 Standards of Care say chromium, magnesium, herb and spice supplements are not recommended for blood sugar benefit (ADA, Standards of Care 2026).
Sugar Reset holds 0.7 mcg of chromium per serving and a 200 mg blend of 22 ingredients. All six ingredients its sales page names are on the label, but five of them have no printed amount. Gymnema, for example, is at most 25 mg per serving, compared with a typical dose of 400 mg three times a day (LiverTox, Gymnema).
| Question | Lifestyle program | Sugar Reset |
|---|---|---|
| Tested in people with prediabetes? | Yes, large trial | No trial published |
| Result | 58% lower chance of type 2 | Not measured |
| What it asks of you | Activity, food changes, modest weight loss | 1 or 2 droppers a day |

When to call
When should you call your clinician about blood sugar?
Call when a result is new, when you plan a change, or when you feel unwell. Prediabetes care works best as a team.
- After any A1C or fasting result in the prediabetes or diabetes range, to plan a second test.
- Before adding any supplement, so your care team can check it against your medicines.
- When a home reading looks very different from your usual numbers.
Very high readings with extreme thirst or confusion need prompt medical care. Do not wait for your next visit.
FAQ
Prediabetes questions people ask
What A1C level is considered prediabetes?
An A1C of 5.7% to 6.4% falls in the prediabetes range for adults who are not pregnant. Under 5.7% is normal, and 6.5% or higher is in the diabetes range. Doctors usually confirm a result with a second test before making a diagnosis.
Can prediabetes be reversed with lifestyle changes?
A lifestyle program can lower the chance of moving on to type 2 diabetes. In the Diabetes Prevention Program, 7% weight loss and 150 minutes of activity a week cut that chance by 58% over about three years, and by 71% in people aged 60 and older.
How many Americans have prediabetes?
CDC estimates that 115.2 million U.S. adults aged 18 and older have prediabetes. It also reports 40.1 million people with diabetes in 2023, including 11.0 million adults who had not been diagnosed.
Should I take a supplement for prediabetes?
Talk to your clinician first. The ADA does not recommend chromium, magnesium, herb or spice supplements for blood sugar benefit, and no supplement was part of the trial that showed a 58% lower chance of type 2 diabetes. A lifestyle program has far stronger evidence.
Is metformin used for prediabetes?
Some clinicians prescribe it. In the Diabetes Prevention Program, metformin lowered the chance of type 2 diabetes by 31%, while the lifestyle program lowered it by 58%. Whether metformin fits you is a decision for you and your prescriber.
What is a normal fasting blood sugar for adults?
A fasting plasma glucose of 99 mg/dL or lower is normal for adults who are not pregnant. A result of 100 to 125 mg/dL is in the prediabetes range, and 126 mg/dL or higher is in the diabetes range, usually confirmed with a repeat test.
Can Sugar Reset help with prediabetes?
No study shows that it does. Sugar Reset has no published trial, its chromium is 2% of the Daily Value per serving, and its herbs come in small, hidden amounts. It does not replace a lifestyle program or any care your clinician recommends.
