3 Must-Have Natural Weight Loss Supplements
Diet pills, fat burners, weight loss aids, appetite suppressants, whatever you want to call them are, there’s no shortage of pills, powders, and potions marketed to enhance weight loss.
When you consider that ⅔ of the adults in the United States and ⅓ of the world’s population are overweight and that approximately 40% of the population is on a weight loss diet at any given time, it’s easy to understand why fat burners are in high demand.
Yet, by and large, most “fat burners” are nothing more than over-priced placebos that do little to actually help people lose weight.
We’ve assembled a list containing 3 of the best natural weight loss supplements backed by research.
Let’s get right to it!
Stim-Free Weight Loss
Pyretic is a stimulant-free fat loss support formula containing natural ingredients to support fat burning, metabolism, and appetite suppression.
3 Great Natural Weight Loss Supplements
Without question, the most popular fat loss supplement is caffeine. It’s been studied thousands of times, proven safe when consumed in reasonable doses (the same of which can’t be said for other common weight loss aids), and effect.
You know caffeine gives you greater energy and alertness, but have you ever stopped to think about how caffeine increases energy?
The primary way in which caffeine exerts its energy and mood-enhancing effects is through antagonism of adenosine receptors. Adenosine is a neurotransmitter that’s associated with feelings of fatigue and lethargy.
FYI, adenosine also forms the “backbone” of ATP.
Since caffeine resembles the shape of adenosine, it can dock to adenosine receptors and “block” adenosine from binding. In doing so, caffeine increases wakefulness and alertness.
But that’s not all.
Second, to antagonizing adenosine receptors, caffeine also increases the production of dopamine (a mood and motivation molecule) as well as adrenaline -- one of the most important fat-burning catecholamines in the body.
More specifically, adrenaline can cause an increase in an individual’s metabolic rate.
Caffeine also enhances weight loss through a number of indirect mechanisms as well. Studies demonstrate that caffeine may help[3,4,5,6]:
- Stimulate lipolysis
- Increase energy expenditure
- Reduce appetite
- Enhance the effects of other fat burning supplements
- Boost exercise performance (which helps increase the number of calories burned during training)
Yohimbine is a powerful alkaloid extracted from a species of African plant called Pausinystalia johimbe ( or simply yohimbe). Research has shown it to be an effective supplement for losing weight, but the manner in which yohimbine helps burn fat is a bit tricky.
Adipocytes (your fat cells) contain two types of receptors that dictate fat storage (alpha receptors) or fat release (beta receptors). Lipolysis is the process by which fatty acids stored in fat cells are released into the bloodstream to be burned for energy.
Now, when fat burning catecholamines, such as adrenaline and noradrenaline, bind to beta receptors, fat cells “unlock”, initiating lipolysis, and stored fatty acids are available for beta-oxidation. However, when catecholamines bind to alpha receptors, lipolysis is for all intents and purposes stunted.
These receptors are at the core of your “stubborn fat” problems, as the areas of fat on your body that are the most difficult to lose contain high amounts of alpha receptors and lower amounts of beta receptors.
Now, here’s where yohimbine comes in as the ultimate “stubborn fat” burner.
Yohimbine blocks alpha receptors, which leaves more catecholamines available to bind to beta receptors, free the stored fatty acids, and allow you to burn stubborn belly fat.
Now, yohimbine isn’t all rainbows and sunshine, it does come with one “catch” -- elevated insulin levels reduce its effectiveness.
In other words, if you want more than just the stimulatory actions of yohimbine, you need to take it in a fasted state.
Yohimbine’s benefits extend beyond supporting fat loss -- research shows that it may also improve exercise performance as well as reduce physical fatigue and increase time to exhaustion.
Forskolin is the bioactive compound present in the Ayurvedic plant Coleus forskohlii. It has a long history of use in Traditional medicine for combating disorders of the respiratory and cardiovascular systems.
Studies have shown that supplementing with forskolin may increase levels of a molecule known as cyclic adenosine monophosphate, or cAMP for short.
cAMP serves as a very important intracellular "messenger” that impacts numerous physiological processes including the metabolism of sugar, fats, and glycogen.
cAMP and ATP (the cellular “currency” of energy production) have a rather unique relationship inside the cell.
When ATP levels are high, cAMP signals to the cell that it has plenty of energy. This tells your body it needs to store nutrients and build tissue.
However, when cAMP levels are elevated, it signals to the cell that ATP is low, which causes the cell to initiate processes to generate more ATP by using its stored energy (i.e. fat).
Forskolin triggers the enzyme adenyl cyclase, which converts ATP to cAMP, leading to a significant increase in the amount of cAMP in a cell, subsequently igniting the energy-burning processes.
Studies have demonstrated that supplementation with forskolin speeds up fat loss and boosts testosterone levels.[17,18]
There’s no shortage of overpriced, underdosed products claiming to be “natural” weight loss supplements on the market.
That’s why we created this list.
To point you in the right direction of which ingredients to consider when looking for added weight loss support.
