How Can an Appetite Suppressant Help Me?
Appetite suppressants help you lose weight faster than weight loss pills, independent of exercise.
When combating excess weight, you often have to diet, exercise, or do both. As effective as these two strategies are, the results take longer than most people have the patience for. Additionally, self-discipline plays a very big role in the maintenance of these two habits. This is where appetite suppressant pills come in.
These pills help you eat less by controlling your hunger and decreasing your appetite, independent of the strength of your will, or lack thereof. The best ones in the market come with thermogenic ingredients that naturally enhance the oxidation of fat. Some have even been documented to prevent the formation of new fat cells.
Will These Appetite Suppressants Help Me Lose Weight?
Yes. All the appetite suppressants on this list have a well-documented history of helping people shed off pounds fast. Just remember that these suppressants are only as effective as your dedication to the manufacturer’s recommended dosage.
How Do Appetite Suppressants Work?
Hunger and appetite are your body’s reminder that you need to eat and boost your energy levels. Natural appetite suppressants interfere with the hunger response in three ways:
Keeping You Feeling Full
Suppressant appetite pills are typically very rich in fiber. Fiber stays longer in your stomach, making you feel full. An empty stomach is usually the trigger for the hunger response: The fuller you feel, the lower your appetite.
Glucomannan is an especially important fiber in this regard. It’s water-soluble, among the most viscous fibers known today. Once in your gut, it absorbs water and expands to fill your stomach for longer.
Increasing Available Energy
Hunger is all about energy. If you can keep your energy levels high without eating extra, you can control your appetite. Thermogenic hunger suppressants increase your energy levels by boosting fat oxidation — the burning of fats to produce energy.
Mitigating Emotional Eating
Eating is often used as a coping mechanism. To suppress the appetite, some pills contain minerals like B vitamins and caffeine, which have been documented to help your moods — essential when you want to include exercise in your weight loss management program. They also help you overcome the crankiness that is brought about by dieting   .
How to Use Appetite Suppressants?
Each suppressant is unique, always follow the manufacturer’s recommended dosage. Also, be mindful of the time of dosage. Pills that have a high-fiber content, especially glucomannan, are best taken before a meal. Pills with high-caffeine content are also time-sensitive. If you take them too late into the day, they’ll interfere with your sleep.
Are There Any Side-Effects When Using Appetite Suppressants?
Anything suppressing appetite affects your metabolism and is sure to have an effect on how your body operates. Natural appetite suppression is pretty harmless in this regard. Most side-effects recorded are typically from reactions with other medications.
As a rule of thumb, always consult a doctor if you have any underlying conditions, or are currently on some other medication, before popping anti-appetite pills.
All the hunger suppressants featured in this article are all-natural, minimizing the risk of reaction. That said, you need to be sure that they won’t interfere with, or react with, any current medications you’re taking.
You should also consult a doctor if you’re pregnant. Pregnancy is highly influenced by hormonal changes: These pills have been shown to influence your hormones — partly because they affect metabolism.
What’s the Difference Between Appetite Suppressants and Other Types of Weight Loss Pills?
Most weight loss pills are prescription drugs, DEA schedule IV. Traditional appetite suppressants are nonprescription.
Only five weight loss compounds are FDA approved: liraglutide, naltrexone-bupropion, orlistat, phentermine, and phentermine-topiramate. If you must take weight loss pills, only get them by prescription, and even then, only from approved outlets.
The 11 appetite suppressants discussed in this article are all natural — meaning they contain no synthetic compounds whatsoever. The advantage of this is that the risk of allergic reaction is greatly reduced.
In a Nutshell
It is important that you manage your appetite and cravings as you work towards a healthier diet and lifestyle. Appetite suppressants help you manage your weight even before you get a handle on the discipline necessary to nurture healthier habits. The products featured on this list are all-natural.
A good number of these products have moneyback guarantees. You can buy, test them, and return them if they don’t deliver on the promises. That said, it’s always important to seek the opinion of a medical professional if you have underlying health issues, or you’re pregnant.
