Mega Diet Review - Does This Supplement Work? Is the lack of continuing support a deal breaker?

Editor's Review: 3.5 / 5.0
Mega Diet Review

It’s remarkable how quickly weight loss supplements enter and leave the market. We often see those products which are less effective leave as rapidly as they entered. While looking at Mega Diet we realized the company that makes it has made some major changes, so we examined it further to find out what you need to know.

EDITOR'S TIP: Substitute Mega Diet with a proven fat burner such as Leptigen for better results.

What You Need to Know

Mega Diet was a weight loss supplement manufactured by Clark Enterprises. While it is still available from some online retailers, the official website does not appear to promote the product any longer. The cost of a monthly supply of Mega Diet is about $100.

Mega Diet was reported to help dieters lose weight up to 200 times more quickly than with diet or exercise alone, but read on…

Continuing Support?

While it is still possible to find Mega Diet occasionally, the company is no longer advertising the product or supporting it in any way. This means that customers who decide to take the risk and purchase it will have no way to receive a refund should it not work for them.

According to our research editor, “Usually, a company will only cease support and advertising for a product if they know the product is inferior.”

Scroll below for one of the best products we’ve seen over the last year.


Ingredients in Mega Diet include 7-Keto, cerecal, synephrine, green tea leaf extract, synephrine, royal jelly, and ginseng.

Green tea has the ability to increase metabolism and energy. Synephrine has thermogenic abilities. 7-Keto was reported to have thermogenic properties as well, but research supporting that was never convening. However, most of the remaining ingredients have minimal weight loss properties.

The Science

While the company website does provide some diet and exercise tips that do have scientific basis, there is no scientific evidence that Mega Diet is an effective weight loss supplement. There is actually very little scientific support that most of the main ingredients were effective in promoting weight loss on their own.

The Bottom Line

When we consider the extremely high cost of the product when it can be found, the lack of scientific evidence supporting the product as a whole or the individual ingredients, and the fact that even the manufacturer no longer supports their own product, we simply cannot recommend Mega Diet.

Individuals who are interested in a product that will help facilitate their weight loss goals would be far better served by looking for a supplement that has scientifically proven ingredients, and the full support of the company that makes it.

We have found both of these requirements in Leptigen. The company that makes the supplement has taken the time to support the weight loss claims with clinically tested ingredients. Further, we found no negative reviews from consumers who have tried the product, which indicates it is working as advertised.

In fact, the company that makes Leptigen is so confident that their product will satisfy dieters, they are giving new customers a special trial offer, which we find generous and reassuring.

Mega Diet is a weight loss supplement from Clark Enterprises, although the company website does not appear to provide this particular product for sale at this time. We were also unable to find Mega Diet on any other retail website, making us wonder if this product has been removed from the market. However, we will take a closer look at the information provided about Mega Diet on the company website to see if there might be a reason why this product is no longer offered.

Mega Diet claims to assist individuals with losing weight and body fat 200 times faster than diet or exercise alone. While the website does provide a list of the key ingredients in Mega Diet, it doesn't appear to provide a complete ingredient list. There are also a number of weight loss tips listed on the product page, although most seemed to deal with overcoming the mental challenges of losing weight instead of the physical ones.

List of Ingredients

According to the company website, the key ingredients in Mega Diet include 7-Keto, cerecal, synephrine, garcinia cambogia, green tea leaf extract, ginseng and royal jelly. Green tea is a common ingredient in weight loss supplements, due to its ability to rev up the metabolism and help dieters make the most of their workout time. Synephrine, also known as citrus aurantium, is also used in weight loss products because of its thermogenic abilities. However, the other ingredients in this formula appear to be sketchy at best in terms of effectiveness in weight loss.

The ingredient 7-Keto is said to be the main ingredient of this formula, because of its supposed thermogenic properties. However, studies done on 7-Keto for weight loss have been inconclusive at best. Cerecal is touted as a starch blocker, but there is little information about this ingredient in weight loss products. In fact, Mega Diet is the only supplement we have found that includes this ingredient. Garcinia is another popular ingredient in weight loss supplements because it is thought to prevent calories from converting to fat. However, the jury is still out on this ingredient as well. Royal jelly has been shown to lower cholesterol in some people, but others have also experienced a severe reaction to the substance.

Product Features

A 30-day supply of Mega Diet did cost $96.50 the last time it was available for purchase. Perhaps this exorbitantly high price tag is one of the reasons the product no longer appears to be available.

  • The product contains green tea and citrus aurantium.


  • The product does not appear to be available through the company any longer.
  • Most of the ingredients listed are not proven weight loss substances.
  • Mega Diet is extremely expensive.


Since Mega Diet appears to be no longer available, our recommendation may be moot. However, we do not see much in this formula that will offer much weight loss assistance. We recommend consumers look elsewhere, to proven ingredients and formulas, for their diet needs.
