Fitbites BHB Gummies Reviews – Do Exogenous Ketones Really Work That Well?

Fitbites bhb gummies is a new product on the market that actually contains exogenous ketones.

The ketogenic diet is currently experiencing a real boom in the health and fitness sector.

However, this trend has also led to many supplement manufacturers using the term “keto” for their products, even though these have no connection to ketosis.

Almost all of these new weight loss gummy bears that are currently available on the German market contain only apple cider vinegar extract and ginger.

I was all the more surprised when I discovered these Fitbites BHB Gummies with real exogenous ketones a few weeks ago.

While exogenous ketones have been available in the USA for a very long time, the demand for exogenous ketones in Germany has also increased sharply in recent years. According to a study by the market research company Euromonitor International, the German market for exogenous ketones will grow to 100 million euros by 2025.

I ordered these Fitbites BHB Gummies myself about 3 weeks ago and will tell you about my own experiences with this product further down in the article.

Since an individual product evaluation is always subjective, I also looked for scientific studies and publications that could confirm a possible effect of exogenous ketones.

To avoid a conflict of interest, I only analyzed and evaluated independent studies and none that were commissioned by the manufacturer.

But let’s first take a look at the ingredients in the Fitbites BHB Gummies.

Fitbites BHB Gummies Ingredients

Magnesium Beta Hydroxybutyrate

What is beta-hydroxybutyrate (BHB)?

BHB (beta-hydroxybutyrate) is a ketone body that is produced by the liver from fatty acids when the body runs out of glucose is available.

This is the case with prolonged fasting or a ketogenic diet.

Our organism has to resort to another source of energy and then taps into our fat stores. He then creates these ketones from the fatty acids, which is called ketogenesis

Why is so much fat “burned” in ketosis?

Carbohydrates are our body’s preferred source of energy. As long as it has enough carbohydrates available to it in the form of glucose, it uses these as fuel and does not affect our body fat.

Unfortunately, in today’s affluent society, this is usually the case. Our glycogen stores are constantly being replenished, so for most people they never really become empty. This means we always have enough fuel available and the fat deposits on our hips remain untouched.

But what happens if we stop consuming carbohydrates for a longer period of time?< /strong>

If we don’t consume carbohydrates for a long time, the carbohydrate stores in the muscles and liver will eventually be emptied. This takes around 10 to 12 hours (without exercise).

Now there is no more glucose available, but the body urgently needs to find fuel for energy production.

What does the body do then?

When carbohydrate stores are exhausted, the body has to resort to another source of energy. It now accesses the fat reserves in our fat cells and converts them into ketones.

The first step in ketogenesis is beta-oxidation. During beta-oxidation, fatty acids are broken down into smaller molecules called acetyl-CoA. Acetyl-CoA is an intermediate in the metabolism of fatty acids.

Acetyl-CoA is then converted into ketone bodies. This process is catalyzed by the enzyme HMG-CoA synthase.

There are three types of ketone bodies:

  • Acetoacetate
  • Beta-Hydroxybutyrate (BHB)
  • Acetone

But why does our metabolism actually need ketone bodies and doesn’t just take normal fatty acids?

But the problem is our brain

Our brain requires about 20% of the body’s total energy, but is very selective when it comes to energy supply from nutrients.

The blood-brain barrier (BBB) is a semi-permeable membrane that protects the brain from harmful substances in the blood. However, fatty acids are too large to pass through the BBB. Ketones, on the other hand, are smaller and can pass through the BBB without any problems.

Ketone bodies can only be used by the brain and muscles if certain enzymes are formed. These enzymes are only formed gradually, so it can take up to 3 days to reach ketosis.

What are the benefits of exogenous ketones (BHB) like with the Fitbites BHB Gummies?

Why not just wait until the body produces its own ketone bodies?

We distinguish between the following ketones:

Endogenous ketones are produced by the body from fatty acids
Exogenous ketones are produced synthetically

It can take anywhere from 48 hours to a week to reach the state of ketosis.

As a general rule of thumb, you shouldn’t eat more than 20 to 50 grams of carbohydrates per day to stay in ketosis.

20 to 50 grams of carbohydrates is a relatively small amount. It corresponds approximately to:

  • 20 grams of carbohydrates: One slice of bread, one medium banana, one cup of milk
  • 50 grams of carbohydrates: Two slices of bread, one large banana

You can determine whether you are in ketosis using special test strips in your urine.

How can you lose weight with exogenous ketones, like in the Fitbites BHB Gummies?

Exogenous ketones can help with weight loss by:

  • Making it easier to get into ketosis
  • Suppress appetite: Ketones can suppress appetite, which can lead to lower calorie intake.

Studies have found that exogenous ketones theGrehlin level as well as the concentration of cholecystokonin strong> and leptin influence and thus create a feeling of satiety in the brain (1)

Fitbites BHB Gummies Side Effects – Risk

Are the Fitbites BHB Gummies harmful or even dangerous to your health?

No, on the contrary. In addition to their positive effect on weight loss, exogenous ketones have a number of potential health benefits, including:

  • Improve cognitive function: Studies have shown that ketones can improve cognitive function, particularly in people with Alzheimer’s dementia or Parkinson’s disease. Illness.
  • Protection against neurodegenerative diseases: Ketones can protect nerve cells from damage caused by oxidative stress and inflammation.
  • Increasing Endurance Performance: Ketones can improve endurance performance by providing an alternative energy source for muscles.
  • Reducing the risk of cancer: Studies have shown that ketones can reduce the risk of cancer.
  • Improving Heart Health: Studies have shown that ketones can improve heart health by lowering cholesterol and blood pressure.</li >

It is important to note that these studies are only preliminary and further research is needed to evaluate the long-term health effects of exogenous ketones.

In a medical report in the Deutsches Ärzteblatt, Dr. Martina Lenzen-Schulte reviewed the studies of the researcherDr. Sarah Hallberg from the Virta Health Center in Lafayette, Indiana/USA.

Dr. Hallberg was able to show that exogenous ketones can lead to a significant improvement in blood values and body weight in people with type 2 diabetes.

Fitbites BHB Gummies my personal experiences

I’ve been testing the Fit Bites BHB Gummies for 2 weeks now and I’m really impressed.

I have used products with exogenous ketones years ago.

I often practice intermittent fasting with the 16/8 variant. I can eat for 8 hours and then have to fast for 16 hours.

Exogenous ketones help me greatly to bridge these 16 hours. The feeling of satiety is much stronger and longer lasting than with bulking agents such as glucomannan.

With exogenous ketones it usually takes a while until you feel full. However, with the Fitbites BHB Gummies I immediately felt an appetite suppression. I attribute this to the pectin, which is also contained in the Fit Bites Gummies.

For the Fit Bites test, I ate very little all day and skipped dinner completely. When I was hungry, I took one of the fruit gummies before going to bed.

If I normally go to bed without eating, I wake up after 3 hours at the latest feeling very hungry, which then leads to me raiding the fridge.

However, after taking the Fit Bites Gummies, this was not the case. The feeling of fullness continued even after I woke up the next morning.

Fitbites BHB Gummies Review – Criticism

Personally, the Fitbites BHB Gummies definitely convinced me.

To be honest, I have to mention that exogenous ketones cannot put the body into ketosis without a reduction in carbohydrates.

Weight loss is primarily based on the increased feeling of satiety and the resulting reduced food intake.

I also find it positive that I can concentrate much better after taking exogenous ketones.

The exact way ketones improve thinking is not yet fully understood. However, they are believed to improve brain energy supply, promote neuronal plasticity and have neuroprotective effects.

I really like the addition of pectin in the Fitbites BHB Gummies.

Pectin is a water-soluble fiber that is found in many fruits and vegetables.

When pectin swells in water, it absorbs a lot of liquid. This fills the gastrointestinal tract and creates a feeling of satiety. Pectin can also slow digestion, which can help you feel fuller for longer.

I have never found this combination of swelling agents and exogenous ketones in any other BHB product.
