Created by Evolution Nutrition, Lean Mode is a
relatively cheap fat burner with five active ingredients. It’s not a great fat
burner. Most of the ingredients either require more research to determine their
effect on weight loss or are under-dosed, and the two effective weight loss
ingredients are not exactly the best options, they are tier 2 type ingredients.
The two ingredients that Lean Mode gets right are green tea extract and green coffee bean extract. However, they are tier 2 ingredients and we wouldn’t recommend a fat burner where these two are your primary active ingredients. There are far more effective ingredients that should make up the bulk of the formula, such as glucomannan for appetite suppression, and coffee and cayenne pepper for energy and thermogenesis.
At $25 for a one-month supply, Lean Mode fat burner is a cheap option, but you get what you pay for: this is far from the most effective weight loss aid available. Fat burners like Hunter Burn and Instant Knockout Cut are certainly more expensive but they are also much more effective. Each one is full of effective, properly dosed ingredients, and as such, they are worth the extra cost.
Verified reviews of Lean Mode fat burner are
pretty mixed. This fat burner only has 50% five-star ratings on Amazon, which
is low in comparison to the top-rated fat burners. We would expect around 70%
positive reviews for a decent product.
Many of the positive reviews of Lean Mode reported an increase in energy and a reduced appetite. The energy is probably from the green coffee bean extract, which contains caffeine, albeit in lower amounts than in normal coffee. On the upside there weren't many complaints about leanmode side effects aside from that which we'd expect from caffeine.
Negative reviews of Lean Mode simply said it didn’t work, although some also reported an upset stomach. Even many of the three-star reviews stated that the product didn’t work…we’re not exactly sure why anyone would give something that doesn’t work three stars, but ok.
Green Tea Leaf Extract (500mg) - Green tea is a decent weight loss supplement but we’ve always cautioned against it being one of the main ingredients in a fat burner. It has positive effects on metabolism, increasing it slightly, and it has thermogenic properties that also help to burn more calories. Suggested doses ranged from 300-900mg. The 500mg dose in Lean Mode should be sufficient to experience green tea’s weight loss benefits.
Green Coffee Bean Extract (500mg) - Derived from coffee beans that have not been roasted, green coffee bean extract is a popular weight loss supplement. It contains chlorogenic acid, which roasted coffee beans do not due to the effects of the roasting. Chlorogenic acid is thought to inhibit alpha-glucosidase, an enzyme that breaks down carbohydrates. By preventing this enzyme from working, chlorogenic acid prevents the body from absorbing carbs and glucose. This theory is supported by some evidence, including a study that showed a reduction in glucose absorption in a small sample group of 12 participants . While the sample is small, it does indicate that green coffee bean extract might be beneficial for weight loss.
CLA (Conjugated Linoleic Acid) (500mg) - A natural fatty acid CLA is often mentioned as a weight loss supplement and can be found in several fat burners. However, evidence for CLA’s impact on weight and weight loss suggests it is only marginally beneficial. Studies on animals showed very promising results, but when studies were conducted on humans the same benefits did not seem to apply . What’s more, these minor benefits only occur when CLA is taken at very high doses of around 3g per day, which means the dose included in Lean Mode is not likely to have any effect.
Acetyl-L-Carnitine (500mg) - Responsible for helping the body turn fats into usable energy, Acetyl-L-Carnitine is thought to be beneficial for a range of diseases and conditions including Alzheimer’s. Theoretically, it should be good for weight loss, since more Acetyl-L-Carnitine means more fat is turned into energy, but not many studies have suggested a direct connection and things are not always so straightforward in the body. One study showed weight loss from the supplementation of l-carnitine—a derivative of the substance in question—when coupled with exercise . But more evidence is needed to confirm that Acetyl-L-Carnitine is a decent fat-burning supplement. What’s more, recommended doses start at 1.5g per day, three times the dose included in the LeanMode fat burner.
Garcinia Cambogia Extract (250mg) - Thought to be an appetite suppressant and to prevent the body from creating fat storage, garcinia is sometimes found in weight loss supplements. There is some evidence that garcinia can aid weight loss, however, studies show that the results are minor and only short-term .
Lean Mode contains two effective ingredients: green tea extract and green coffee bean extract. Neither are top-tier fat burners, although both do offer some fat-burning benefits. The other ingredients in LeanMode might work, although the evidence suggests that both CLA and acetyle-l-carnitine would need to be included in much higher doses to be effective.
At just $25, Lean Mode is a fairly cheap fat burner but it is also a fairly ineffective one. Customer reviews of Lean Mode reflect this. Many customers found the supplement did nothing at all and some found that it had side effects, such as giving them a bad stomach.
Had Evolution Nutrition included a few much decent weight loss ingredients in Lean Mode we might have been able to call it a mediocre fat burner, but since it includes so little we have to conclude that it’s really not great. Top fat-burning ingredients are missing, like glucomannan, cayenne pepper, and coffee androgens.
For a top-quality fat burner, we recommend trying Hunter Burn. Its unique formula is one of the best we’ve seen and it is very highly dosed to give you a real fat-burning boost. You can read more about Hunter Burn and other top fat burners on our best fat burners list.
