Does Caffeine Help With Fat Burning, or Only With Lab Markers?
Caffeine fat burning is a lab finding more than a scale result. A review of 94 studies found a small overall rise in fat metabolism measures, such as blood markers, and it did not measure body weight. One SodaSlim capsule, a capsule and not a drink, prints 138 mg of caffeine, 34.5% of the 400 mg daily guide.

Does caffeine really speed up fat burning?
Caffeine nudges some lab measures of fat metabolism up a little, but that is not the same as losing body fat. A meta-analysis of 94 studies found a small overall increase in blood markers and gas exchange (Meta-analysis, Does caffeine increase fat metabolism?).
The review tracked short-term markers, not body weight or fat loss.
The sales page says the caffeine "immediately awakens the metabolism". No cited source supports that as an outcome in people.
How much weight does caffeine change in studies?
The effect is small. The NIH says caffeine may help with a little weight loss, but tolerance builds (NIH ODS, Weight loss supplements (consumers)).
One observational finding exists. Men who raised their intake gained 0.43 kg less over 12 years, and women 0.35 kg less (NIH ODS, Dietary Supplements for Weight Loss (health professionals)). That is a pattern, not a test of a capsule.
| Evidence | What it measured | What it does not show |
|---|---|---|
| 94-study review | Fat metabolism markers | Body weight or fat loss |
| Long-term records | 0.43 kg (men), 0.35 kg (women) less gain over 12 years | That caffeine caused it |
What does the SodaSlim label put behind the caffeine claim?
The label puts 138 mg of caffeine anhydrous in each capsule and pairs it with the line "Promotes Energy Production From Fat*". The FDA has not evaluated that claim.
138 mg is 21.0% of the 658 mg listed and 34.5% of the 400 mg guide. Caffeine can also raise blood pressure and heart rate. See our caffeine anhydrous page and metabolism booster claims page.

That depends on your age, heart, liver, medicines and sleep.
Keep taking prescribed medicine. Chest pain, fainting or a racing heart that will not settle need care now.

FAQ01
SodaSlim questions people ask
Can caffeine target belly fat?
No source we read shows that. The 94-study review measured short-term fat metabolism markers, not where body fat sits or how much is lost (Meta-analysis, Does caffeine increase fat metabolism?).
Is caffeine a fat burner or only a stimulant?
It is a stimulant first. The NIH says it may help with a little weight loss but tolerance builds (NIH ODS, Weight loss supplements (consumers)).
