According to their website, 7-DFB (seven day fat burner) is “the ONLY Fat Burner in the World that can help YOU Lose 7, 10, 14, Even Up To 21 POUNDS in Just 7-Days”. They claim the average loser loses 8.75 pounds in 7 days. This 7-DFB review will determine if there is any validity to these lofty claims.

What a long list of ingredients! The 7-DFB website has a description of each ingredient. In addition to those listed on the bottle, they also list Caffeine Anyhdrous, apple pectin, fennel seed, and goldenseal.
This seems strange since these ingredients are not listed on the bottle.

Chromium Picolinate (chromium + picolinic acid) is pushed by companies as an aid to losing weight. It is known that small quantities of chromium are “needed for glucose utilization by insulin in normal health, but deficiency is extremely rare in developed nations.”
Some claim chromium picolinate reduces insulin resistance and leads to weight loss. However, studies show mixed results.

Do you have a chromium deficiency? Probably not.

Glucomannan is a dietary fiber which makes you feel full. Studies have shown it is effective in promoting weight loss, but only if you take 2-4 grams per day. The amount of glucomannan in 7-DFB diet pills is not enough to cause weight loss.

The remainder of the ingredients in 7-DFB might be healthy, but they have no effect on weight loss (unless you call a laxative effect a way to promote weight loss). This 7-DFB review finds there is no ingredient in 7-DFB which has been proven to contribute to weight loss (at least not in proven amounts).
How much does 7-DFB cost?

One bottle of 7-DFB diet pills costs $19.99 for a seven day supply. However, if you join the Orovo club (a multi-level marketing company) you can get a bottle of 7-DFB for about $5 (after you pay full price for one product).

How should 7-DFB be taken?

The recommended dosage is 6 capsules twice a day for seven days. Allow 7-days without using the product in between cycles.
What are the side effects of 7-DFB?

Side effects of 7-DFB diet pills include frequent bowel movements, increased heart rate, and nausea.
Is there a guarantee for 7-DFB?

The 7-DFB website says they will give a full refund if you return your empty bottle (plus any unopened bottles). You will receive a “prompt refund” minus shipping and handling.

7-DFB conclusion

This 7-DFB review finds this is not a typical fat burner. It does not contain ingredients typically contained in fat burners. There are no proven ingredients in 7-DFB diet pills. Any claim that you can lose 21 pounds in seven days should be a huge red flag. Maybe you could lose weight on 7-DFB but it would most likely be because you would be stuck on the toilet for a week. If you really want to lose weight, look for a diet pill that includes proven ingredients in proven amounts.
