Evidence Behind The Supplements

The Clean 9 diet includes three supplements that are claimed to help you detox and lose weight.

Aloe Vera Gel

The main supplement in the Clean 9 diet is aloe vera gel.

Aloe vera gel is made up of the inner gel and pulp of the aloe leaf. The rind and outer leaf are removed during processing.

The inner part of the leaf is made up of 98.5–99.5 percent water. The remaining part contains some soluble fiber and sugars.

It also contains small amounts of amino acids, enzymes, vitamins, minerals, trace elements, some organic acids and anthraquinone, a known laxative.

Aloe vera gel has been linked to benefits such as improved digestive health and weight loss. It's also thought to have anti-diabetic, anti-bacterial, antioxidant and anti-tumor properties (1, 2, 3, 4, 5, 6).

Yet the evidence for these effects is mostly anecdotal or based on animal studies. There are very few quality studies in humans to back this up.

One study in rats found that aloe vera may show promise as a weight loss agent (7).

One human study has also been conducted. It followed 136 obese people with untreated type 2 diabetes or pre-diabetes and found that those taking aloe vera capsules lost 4 percent more body fat than those taking a placebo (8).

Nonetheless, the study had some flaws that make it unclear if the fat loss was caused by the aloe vera.

Garcinia Plus

Garcinia Plus capsules contain garcinia cambogia extract.

This is a weight loss supplement processed from a fruit of the same name.

Garcinia cambogia contains high levels of hydroxycitric acid, which is the main active ingredient (9).

Some claim it helps you burn more fat when taken as part of a diet and exercise program and that it helps keep hunger at bay by reducing your appetite.

Animal and human studies investigating these claims have found mixed results (10).

One recent review found that people who took garcinia cambogia lost 2 lbs (0.88 kg) more weight than those taking a placebo. There was no difference in weight when they only looked at the most reliable studies (11).

Overall, it's not clear if garcinia cambogia reduces appetite and helps you burn fat. The evidence is mixed (9, 12).

Forever Therm

The Forever Therm herbal supplement in the Clean 9 diet is claimed to give you an energy boost and increase your metabolism.

The main active ingredients in this supplement are raspberry ketones and green tea extract.

Drinking green tea has been linked with an increase in metabolism (13, 14, 15).

However, its impact on fat burning is thought to be minor and may not apply to all people, especially if you regularly drink beverages with caffeine.

Raspberry ketones are natural compounds found in red raspberries, which have been investigated as a weight loss agent.

To date, nearly all the studies on raspberry ketones have been carried out in animals or test tubes. In these studies, they have been linked with fat burning, but only at very high doses (16, 17, 18, 19).

It would be impossible to reach an equivalent dose in human cells without taking 100 times the maximum safe dose, which is not recommended.

Only one clinical trial has investigated the effects of raspberry ketones in humans. This study did show some weight loss (20).

However, this study can't be used to claim anything about raspberry ketones because it also used diet, exercise and other supplements (20).

Bottom Line: It's not clear whether the supplements included in the Clean 9 diet will help you lose weight or reduce your appetite. The evidence is mixed.

Does The Clean 9 Diet Work?

As with all commercial diet programs, there are many anecdotal reports of both success and failure with the Clean 9 diet.

However, at the moment, there are very few scientific studies investigating the effectiveness of these types of diets.

Although the Clean 9 diet hasn't been formally studied, the plan is very low in calories, so you are likely to lose weight in the short-term (21, 22, 23).

Yet some of the weight lost is likely to be due to a loss of water weight and stored carbs, rather than body fat.

Unless if you make long-term changes to your diet, you will likely regain all the weight you lost as soon as you start eating normally (24, 25, 26, 27).

As for the detox aspect of this diet, many people report an energy boost and feeling better after a period of detoxing. This is most likely due to the elimination of alcohol and other unhealthy foods from your diet, rather than from any special “detox" effects.

Bottom Line: If you stick to the diet, you will lose some weight in the short-term. Whether you maintain the weight loss over time will depend on your lifestyle.

Safety and Side Effects

There are a few side effects and safety concerns to be aware of if you decide to try out the Clean 9 diet.

People who go on very-low-calorie diets may suffer from tiredness, irritability, headaches, nausea and dizziness (28).

Although aloe vera is generally well tolerated and considered safe, it can cause a few unwanted side effects in some people (29).

Some of the side effects of aloe vera reported to the Food and Drug Administration include stomach problems, nausea, dizziness and tiredness. In rare cases, there have been reports of allergic reactions and also liver toxicity with sustained use (30).

It's also not advised in pregnancy or breastfeeding as it can cause early contractions in pregnant women and stomach upset in breastfeeding babies (31).

The Clean 9 diet should also be used with caution in people who have diabetes due to its very low calorie and carb content, coupled with the potential of aloe vera gels to lower blood sugar (32, 33, 34).

The other supplements have no reported side effects. However, side effects and safe doses in these herbs are not very well studied either.

Bottom Line: The Clean 9 diet should be safe for most people. However, some people should avoid it, including pregnant and breastfeeding women.

Take Home Message

If you stick to them, very-low-calorie diets will help you lose weight in the short-term.

The Clean 9 diet is no different. Its structured plan and rules may help some people kick-start a healthy eating plan.

However, this plan is expensive and there is little evidence to support the use of the supplement package.

Additionally, most people who go on diets like this end up re-gaining the weight.

Personally, considering the limited evidence and high cost, I would save my money.

The Clean 9 diet may be useful to some people who want to lose weight quickly for a special occasion, but it's not a solution for long-term health.
