Inmit fasting powder is not obviously a scam, but no published trial shows it helps with weight loss. It is a dietary supplement, so no regulator approved it before sale. Treat the marketing claims as unproven, check the label on your own tub, and speak to a doctor first if you take medicine or have a health condition.
What Inmit fasting powder claims to be
Inmit is sold as a powder to take around intermittent fasting windows. Its marketing says it supports appetite control and supplies fibre, vitamins and minerals. Those are the maker’s descriptions. We have not tested the product.
The one label dataset we could find comes from a nutrition aggregator, which is a last-resort source. It lists a nighttime variant of the product. Aggregator entries can differ from the package, so check the panel on your own tub.
| Per 21 g serving (nighttime variant) | Amount | % Daily Value |
|---|---|---|
| Calories | 65 | n/a |
| Total fat | 0.5 g | under 1% |
| Total carbohydrate | 5 g | 2% |
| Dietary fibre | 4 g | 14% |
| Sugars | 0.5 g | n/a |
| Protein | 10 g | 20% |
Why a fasting powder is not a fast
Here is what most reviews miss. If the listing above is right, one serving carries 65 calories and 10 g of protein. That is food energy, so taking it during a fasting window changes what “fasting” means.
Different flavours and versions of a product can also carry different contents. The older marketing for Inmit mentioned green coffee extract and electrolytes. The aggregator entry shows neither. So two buyers can read two different “ingredient lists” and both be partly right.
Your practical step is simple. Read the supplement facts panel and the ingredient list on the exact product you hold, then decide whether it fits your own fasting plan.
How supplements are regulated
In the United States, the FDA states it is “not authorized to approve dietary supplements for safety and effectiveness before they are marketed.” Firms can lawfully sell them “without even notifying FDA.” The FDA advises people to talk to their doctor or pharmacist before using one.
In the UK and EU, food supplements also reach shelves without a pre-sale efficacy approval. They are regulated as food, and health claims must be authorised before a seller can use them. Rules differ by country, so a US claim on a label does not carry over automatically.
Is Inmit fasting powder legit? What the evidence supports
| Claim you may see | Where it stands |
|---|---|
| Inmit is a real product with a real ingredient list | Supported. It is sold through mainstream retailers. |
| It helps you lose weight | Not supported. We found no published trial on the finished product. |
| 100% natural, so no side effects | Not supported. Natural ingredients can still cause side effects or interact with medicine. |
| Safe for everyone | Not supported. No supplement suits everyone. |
| Increases lifespan | Not supported. No supplement has been shown to extend human lifespan. |
| Controls blood pressure or blood sugar | Not supported. Those are medical claims for a medicine, not a powder. |
| Green coffee extract burns fat | Overstated. The extract still contains caffeine, and US regulators have acted against false weight-loss claims for such products. |
Safety: who should avoid fasting supplements
- Pregnancy and breastfeeding: Speak to your midwife or doctor before fasting or using any supplement.
- Children and teenagers: Fasting aids are not appropriate under 18.
- Diabetes: Fasting can cause dangerous blood sugar swings, especially with insulin or sulfonylureas. Get medical advice first.
- Kidney or heart conditions: Added minerals and fluid shifts matter. Ask your doctor.
- Eating disorders: Appetite suppressants and fasting plans can worsen restrictive patterns. If food feels controlling, contact your doctor, Beat in the UK, or the National Alliance for Eating Disorders in the US.
- Caffeine sensitivity: Caffeine can cause an upset stomach, faster heart rate and trouble sleeping.
How to judge any fasting supplement
- Look for independent testing, such as an NSF or USP mark.
- Check whether the amounts of each ingredient are listed.
- Treat before-and-after photos on a seller’s site as marketing, not evidence.
- Be wary of any disease claim. Those belong to medicines.

Frequently asked questions
A dietary supplement powder marketed for use around intermittent fasting. It is not a medicine, and contents vary by version, so read the label on your tub.
It appears to be a real product, so scam is not the right word. But we found no published trial showing it helps weight loss, so the marketing claims remain unproven.
There is no published evidence that it does. Any weight change during intermittent fasting is far more likely to come from overall eating pattern than from a powder.
If the label lists calories, yes in the strict sense. One aggregator listing shows 65 calories per 21 g serving for a nighttime version. Check your own label.
Nobody can say in general terms. Supplements are not approved by the FDA before sale, and safety depends on your health and medicines. Ask your doctor or pharmacist first.
No. Natural substances can cause side effects and interact with medicine. The word natural has no safety meaning on a label.
People who are pregnant or breastfeeding, under 18, living with diabetes, kidney or heart conditions, or living with or recovering from an eating disorder should get medical advice first.
Look for independent testing such as NSF or USP, a full ingredient list with amounts, no disease claims, and research on the actual product rather than one ingredient.
