What Is Overnight Lean Keto?

Overnight Lean Keto is a weight loss dietary supplement that claims to initiate ketosis in the user’s body. Manufacturers of this product claim that the all-natural ingredients may boost weight loss.

And it supplies the body with exogenous ketones which may jumpstart the process of ketosis just like a ketogenic diet does.

One study on ketogenic diet indicates that when the body is deprived of carbohydrates, it might enter a state of ketosis where the body changes its order of operation to burning fat for energy.[1]

Essentially, this is what this supplement claims to achieve when taken as directed. What is hard to believe, however, is that it promises to deliver this change overnight.

Other claims by these pills include; appetite suppression, maintain a leaner physique, and improves cognitive function.

How Does It Work | The Science Behind Overnight Lean Keto

Overnight Lean Keto works to boost ketosis in the user’s body by providing a steady supply of exogenous ketones. Once the body attains the required level of ketone bodies it enters into the state of ketosis.

In ketosis, the body forgoes burning simple carbohydrates for energy, and instead, it targets fat deposits.

When fat is broken down for energy, the body’s fat mass is reduced which is a plus for weight reduction. Energy harnessed from broken-down fat works in the body for longer and offsets cravings for sugary foods. This ultimately conditions the user to consume less food.

Overnight Lean Keto Ingredients – What to Look For

To deliver all these claims, this product contains a number of active ingredients which include;

BHB ketones – These are exogenous ketones which might help provide the body with an alternative way to raise levels of BHB concentration. A study appearing in the journal Frontiers in Physiology concluded that drinks with exogenous ketones might be effective in reaching ketosis.[2]

Coffee extract – A paper featured in Science Direct claims that coffee extract has the ability to lower the body’s fat accumulation process.[3] This ingredient may do this by regulating both lipid metabolism and adipogenesis in the liver and the white adipose tissues.

Lemon extract – Citric fruits such as lemon contain flavonoids. The flavonoids present in lemon are hesperidin and eriocitin. In a study report in the Journal of Clinical Biochemistry and Nutrition, these flavonoids might help decrease plasma and hepatic cholesterol.[4] This is done through inhibiting the enzymes that synthesize cholesterol and triacylglycerol. Research shows that plant compounds in lemon extracts may help prevent or reduce weight gain in a number of ways.

Garcinia cambogia – The extract used from this plant is the hydrochloric acid (HCA) which is considered to have short term effects on weight loss. An article in the Journal of Obesity points out that, HCA is an enzyme inhibitor and appetite suppressant.[5] It may reduce carbohydrate metabolism. Research determined that diet matters. Garcinia Cambogia was not effective in people following a low-fat diet but in the Journal of Clinical Diagnostic Research found that taking garcinia cambogia extract along with a high-fat diet did reduce weight gain.

Forksolin – This ingredient works to activate the Cyclic Adenosine Monophosphate (cAMP), an enzyme that facilitates the breakdown of fat stored in animal and human cells. The Journal of International Society of Sports Nutrition has an article that adds that forskolin may regulate thermogenesis, boosts basal metabolic rate of the body and increases the body’s fat utilization capabilities.[6]

Final Verdict

Although ketogenic diets are a way to initiate ketosis, the diet is very hard to observe mainly because it is a drastic change to your usual meal and also comes with a number of side effects.[7]

To ease this process, manufacturers have formulated products that contain ketone bodies to ease your way into ketosis.

However, ketogenic boosters such as Overnight Lean Keto also cause side effects which make using it an unpleasant experience as well. Similarly, this product may fail to help you reach your weight goals.

Moreover, this supplement is also not easy to access making it unreliable if you are planning to use it for a longer period.

    This product has not been very effective in my opinion.

    I took these for a month and had to stop. It was gentle enough but they left me feeling sick to my stomach. I just got tired of feeling that way. If there was any benefit from them, it wasn’t much. This product has not been very effective in my opinion.

    By Nancy W 

    Please don't waste your money.

    I wasted my money on Overnight Lean Keto, this is the worst product I ever ordered. It’s not working for me. Now as I have ordered it I have to take the full bottle I’m stuck with it. Please don’t waste your money.
