Prediabetes: What Works, According to the Best Evidence
For prediabetes, what works best is a lifestyle program: about 5 to 7 percent weight loss and 150 minutes a week of brisk activity. In the large Diabetes Prevention Program, that cut the risk of type 2 diabetes by 58 percent. Metformin cut it by 31 percent. No supplement has matched that.

What counts as prediabetes?
Prediabetes means blood sugar is higher than normal but not yet in the diabetes range: an A1C of 5.7 to 6.4 percent or fasting glucose of 100 to 125 mg/dL (NIDDK, Diabetes & Prediabetes Tests).
An estimated 115.2 million US adults have it (CDC, National Diabetes Statistics Report).

- PrediabetesA1C 5.7-6.4%Fasting 100-125 mg/dL
- Diabetes rangeA1C 6.5% or higherFasting 126 mg/dL or higher
Type an A1C or a fasting number to see its range. One test is not a diagnosis; a doctor confirms with a repeat test.
Ranges from NIDDK (NIDDK, Diabetes & Prediabetes Tests). About 115.2 million U.S. adults have prediabetes, many without knowing it (CDC, National Diabetes Statistics Report). Home meters are not diagnostic tests.
What works to keep prediabetes from turning into diabetes?
A structured lifestyle program has the strongest results. In the Diabetes Prevention Program it cut the risk of type 2 diabetes by 58 percent over about three years (NIDDK, Diabetes Prevention Program).
| Approach | Lower risk of type 2 |
|---|---|
| Lifestyle program | 58% |
| Lifestyle, age 60 and over | 71% |
| Metformin | 31% |
What should a prediabetes plan include?
The CDC points to two targets: lose about 5 to 7 percent of body weight and get at least 150 minutes of brisk activity a week (CDC, Prediabetes).

No supplement has shown results like the lifestyle program. NCCIH finds no reliable evidence that any herbal supplement can help control diabetes (NCCIH, Diabetes and Dietary Supplements).
Glyco Defender has no published human trial, and its chromium is 7 mcg. If you try a supplement, treat it as an extra, never the plan. See insulin resistance basics.
If you take metformin or another medicine, keep taking it and talk to your doctor before adding anything.

FAQ01
Questions about prediabetes
Can prediabetes go away?
It can improve, and lifestyle change is the best-studied way to lower the risk of type 2 diabetes (NIDDK, Diabetes Prevention Program). Only repeat testing can show where you stand. Follow your doctor's advice on how often to check.
How much weight should I lose with prediabetes?
The CDC suggests about 5 to 7 percent of body weight (CDC, Prediabetes). At 200 pounds that is roughly 10 to 14 pounds. Slow, steady loss that you can keep is more useful than a fast drop.
Is metformin used for prediabetes?
Sometimes. In the Diabetes Prevention Program it cut risk by 31 percent, less than the lifestyle program (NIDDK, Diabetes Prevention Program). Whether it fits you is a decision for your doctor, not a label.
