Total Lean Burn 60 Facts

  • Manufactured by GNC
  • 60 pills per bottle; 30 servings
  • Fat burning/energy pill

As the name suggests Total Lean Burn 60 is a supplement manufactured for GNC, GNC Holdings, Inc., headquartered in Pittsburgh, PA is a trusted company who have been providing nutritional supplements for over 15 years.

As you would expect GNC have good customer service and although some customers may be unhappy with some of the supplements the company have a great image.

This supplement is unique in that a small clinical trial has been conducted on the product itself, the details of the trial can be found here.


Essentially, it is a chart which shows the difference between the calories burnt post workout when using Lean Burn or a placebo. The chart is explained by the following paragraph:

Clinically proven to increase post workout calorie burning by up to 60% for up to one hour after a workout. This double blind placebo controlled crossover study consisted of 22 healthy men and women. Participants exercised on a treadmill on two occasions. On one occasion they took Burn 60 before exercise and on the second, they took a placebo. The amount of calories burned during the first hour post exercise was measured and participants burned up to 60% more calories while on Burn 60 compared to when they took the placebo.

It’s worth remembering that this is a very small study, and only looks at the calories burnt in the hour following exercise. It is unknown how long Lean Burn works for or how long it stays in the system. Further to this, the body always burns more calories after a workout, and so it is unclear how much the use of Lean Burn would increase calorie burn without exercise. This information about the product is promising, but still preliminary.

Luckily the recommended usage is to take two tablets 30-60 minutes before starting exercise on workout days, whilst on non-workout days users should take two tablets with water before breakfast. Because of their caffeine content, consumers should not take prior to bedtime. We would suggest that the latest these tablets should be taken is 4 or more hours before bedtime, depending upon the individual’s tolerance or sensitivity to caffeine.

GNC Total Lean Burn 60 Concerns:

  • Study is small and overstates products capabilities
  • Negative side effects
  • Not suitable if stimulant sensitive

What Does GNC Total Lean Burn 60 Claim To Do?

GNC Total Lean Burn lists the following properties:

  • A powerful thermogenic formula
  • Increases calorie burning by up to 60%
  • Boosts energy and metabolism

So What Is GNC Total Lean Burn 60 and What Are The Ingredients?

The ingredients used in Total Lean Burn are outlined on the website and the amounts stated. It contains a reasonable amount of caffeine in each serving size of 2 tablets.

  • Guarana Seed Extract (Paullinia cupana)(36% Caffeine = 180 mg) (495 mg): A berry that is naturally high in caffeine, it is often an ingredient in energy drinks and diet pills. Numerous studies have shown that caffeine boosts energy levels and alertness, as well as mildly boosting the metabolism, causing a small increase in the number of calories used by the body. The effects shown in studies are small, and some studies are inconclusive.
  • Black Tea Leaves Extract (272 mg): Black tea is another source of caffeine. Studies have also suggested that black tea leaves contain high levels of some polythenols, which have caused weight loss in rats on high fat diets, by inhibiting absorption of fat from the intestines.
  • MegaNatural Grape Skin and Seed Extract (Vitis vinifera) 210 mg):
  • MegaNatural 125 mg): Meganatural is a range of grape extracts that have been proven to lower blood pressure and to lower blood sugar levels. The GNC website does not specify which type of MegaNatural is used, which is frustrating. We emailed but to date have no further information. We will update this once (if) we manage to receive feedback.
  • Ginger Root Extract (Zingiber officinale) 200 mg): Some studies suggest that ginger root is an appetite suppressant. One study used dried ginger powder to make a tea that participants drank with breakfast. Researchers found that satiety levels were much higher when the tea was consumed with breakfast, rather than just the breakfast on its own.
  • Dill Weed Extract (Anethum graveolens) 5 mg): Dill weed is thought to be effective in stabilising blood sugar levels, although all research has been in rats. It is also used as a digestive aid, as it can relieve cramping and stomach pain.

The product is also cinnamon flavoured, with cinnamon bark being listed amongst the non-active ingredients. Cinnamon bark is used to treat stomach issues such as diarrhoea and flatulence. There are also some studies that suggest that cinnamon consumption can lead to increased lean muscle mass and slight body fat decreases. However, the amount used in GNC Total Lean Burn to flavour it may not be sufficient to have any impact upon weight loss.


So What Does All This Mean?

In general, one of the primary purposes of GNC Total Lean Burn is to boost energy levels during exercise, and the ingredients do provide this energy boost, primarily through caffeine. As well as boosting energy levels, caffeine increases the body’ metabolic rate temporarily, which can lead to an increased rate of weight loss, provided the user is following a diet that contains less calories than they burn each day.

Even though Total Lean Burn is not marketed as an appetite suppressant, it contains ginger, which has been proven to mildly suppress the appetite, leading people to eat less in a meal following its consumption.

Depending upon the type of meganatural that is being used, this ingredient will either lower blood pressure or will lower blood sugar levels. Lowering blood pressure would help to counteract any increase in blood pressure that the caffeine may cause, and could have a beneficial effect for dieters in terms of their general health. Regulating blood sugar levels could help to prevent crashes in blood sugar after eating, which could reduce snacking, and be felt as a reduction in appetite or sugary food cravings.

Does GNC Total Lean Burn 60 Have Any Side Effects?

Some customers have reported side effects when leaving reviews on the GNC website. These include:

  • Increased blood pressure
  • Jitteriness
  • Nausea
  • Increased heart rate
  • Light-headedness
  • Cramping

These are all fairly common side effects from the consumption of a large amount of caffeine, and so consumers should ensure that they are not ingesting caffeine from other sources whilst using this product. Taking the pill with a meal, rather than on an empty stomach might also help to reduce these symptoms, especially jitteriness and nausea.

Caffeine has numerous side effects that are associated with its use. These include headaches, nausea, jitteriness, increased urination, dehydration, insomnia, increased heart rate, increased blood pressure and even heart palpitations.

Avoid if you are pregnant or breast-feeding.

Any GNC Total Lean Burn 60 Reviews From Customers?

The GNC website has a very well established review system, which usually attracts numerous reviews. GNC Total Lean Burn has over 230 reviews on the official website, with a slightly better than average rating of 3.8 stars. Reviewers can select a number of pros and cons to add to their review, and the reviews page provides stats about these; over half of the reviewers added that the pills boost energy. 75 people added the tag “no side effects”, whilst 32 tagged “caused side effects”. Obviously not all customers fill in this part of the review, but it does act as a good overall indicator.

Negative reviews mention side effects, a lack of weight loss and no boost of energy.

I started to take this product along with the shake following the instructions. After like 2wks I started to feel a hollowness/weakness in stomach/edginess after 15mins of taking the pills but proceeded to take them anyways. It continued to happen until the last few pills in the bottle I ended up having to go to the doctor due to my blood pressure sky rocketing. The doctor DID NOT recommend these pills.

I had some downright scary side effects from this supplement. I had god awful cramps in my lower abdominal area, began feeling light headed, and my heart began racing constantly. I tried working out with this supplement in my system a total of 5 times, and finally had to stop due to the side effects as I felt they were just too dangerous.

I just started taking this a few days ago but I don’t feel that it has any effect on my energy level or curbing my appetite. I will continue with it though to see if it just takes longer to start feeling effects and results.

On the other end of the scale, many customers are incredibly impressed with this product, and have achieved a significant amount of weight loss with its use:

I gained a lot of weight over the course of my first year of university. In November of 2013, i weighed in at 225 pounds. By March of 2014, with dieting a low carb high protein diet and excersizing everyday along with taking two burn60 pills every morning,i lost 50 pounds. I have still maintained my weight loss, even with easing off my strict diet. To date, i am still around 175 pounds (give or take a pound per week). I recommend these pills to everyone. They work wonders.

I love this product. It gives me a great energy boost. I feel like I sweat 10 times as much in the gym. I feel like I get another burst of energy when working out. I think it does what it’s supposed to do. I do not feel like it makes my heart race I like there are side effects. I only use it when I’m going to work out though. I do not use it on a daily basis if I do not plan to work out. I take two pills 30 minutes before heading to the gym.

Plenty of customers mention that it seems to curb their appetite, with 68 reviews being tagged with ‘curbs appetite’. This is despite the product never claiming to be an appetite suppressant. Ginger has been found to have a mild effect upon appetite when drank as a tea, and so it may work when in tablet form also.

Use this product mostly to boost energy and it does a great job curbing my appetite.

So Does GNC Total Lean Burn 60 Work?

GNC Total Lean Burn does seem to significantly boost energy levels in the majority of consumers. Because the energy boost comes primarily from caffeine, those who are very tolerant of caffeine are less likely to notice any effects, although it will still mildly increase their energy levels and metabolic rate for a few hours. Even though it is not marketed as an appetite suppressant, the ginger in the pills do seem to have an effect that many people notice. Finally, there is some preliminary clinical evidence that this diet pill does increase calorie burn following a workout, which is why the product is recommended for use just before exercise.

As to whether or not customers can lost weight by using this product, it depends upon the individual. The more exercise they undertake, the more calories they will burn, and this is accelerated by the diet pill. If the consumer is making sure that their diet is calorie restricted, they will lose weight.

GNC Total Lean Burn merely helps to widen the gap between the number of calories burnt each day and the number of calories consumed, which will help to accelerate weight loss. As with all diet pills, the rest is up to the individual user.

Where Can I Buy GNC Total Lean Burn 60?

GNS Total Lean Burn can be purchased from the GNC official website or any GNC retail store. Its original price was $36.99 for a bottle of 60 tablets, but it has now been reduced to $24.99. It is unclear at this time if this is a temporary or long term sales price.

GNC members can purchase the bottle for $21.24. Members are people who have purchased an annual GNC gold membership card at a price of $15.00 per year, which grants them additional discounts on many of the products available at GNC. This may be a good investment for those who shop at GNC regularly, but for many the cost of the membership would outweigh savings made on just a few purchases over the course of the year. Shipping costs on all deliveries is a flat rate of $3.99.

What About A Guarantee

GNC offer a 30 day money back guarantee on unopened and unused products, minus the cost of shipping. This is valid from the date of the order.

Watchdog Verdict

Overall, GNC Total Lean Burn has left a lot of customers very happy with the product and their weight loss. However, it may not be suitable for people who are sensitive to caffeine and other stimulants, or who have elevated blood pressure or other heart related health concerns already.

The study associated with the product is preliminary but promising. However, in order to lose 1lb of fat, a person has to burn 3,500 calories more than they have consumed. As we know that the product increases calorie burn in the hour after exercise by around 80 calories, it is possible to see that this will only contribute to weight loss in a small way as a fat burner. It is more likely to aid significant weight loss by motivating the user to exercise regularly, as well as to increase their energy whilst exercising, allowing them to push harder and work out for longer.

The side effects do not affect the majority of users, but are still worrying for the few people who are affected by them. People who experience negative side effects should reduce their intake of the diet pill, or ideally stop use of the product completely.

Overall, the product appears to be good, especially when presented with clinical evidence. However, upon closer inspection, GNC Total Lean Burn just is not as good as the company makes out.
