Capsaicin has been shown to be an effective appetite suppressant as well. Studies have shown that a breakfast containing capsaicin leads to decreased fat and protein intake at lunch.

Data also shows an increased energy expenditure of the body while ingesting capsaicin. In stores, capsaicin supplements can be found with other vitamins and supplements, but you may have to look for them under the names capsicum, cayenne, or cayenne pepper.

You should not take a capsaicin supplement if you have a history of stomach ulcers. These supplements can cause gastrointestinal irritation. Glucomannan is a water-soluble fiber and dietary supplement derived from the konjac root that is thought to be an effective appetite suppressant by some.

It is available in capsule form and found in the vitamin and supplement section. Glucomannan may act as an appetite suppressant when taken approximately one hour prior to each meal. Fiber, like glucomannan, is thought to expand in the stomach and increase the feeling of satiety, or fullness.

Glucomannan has very few adverse events associated with its use, but data suggests that it may not cause a significant positive change to body weight or the feeling of fullness overall.

Speak to your doctor or pharmacist for additional information before taking a glucomannan supplement, as there may be more appropriate options for you. Psyllium husk is a dietary fiber most commonly known by the brand name Metamucil. Like other fibers, it expands in the stomach and can increase the feeling of fullness while helping control blood sugar spikes.

It is available commercially in many forms, including powder, capsules, and wafers. Studies have shown a decreased desire to eat and increased fullness upon consumption when psyllium products are taken prior to breakfast and lunch.

However, fiber products with adequate fluid intake can be healthy for the bowels and make bowel movements more regular. Flaxseed is a plant-based food that is a good source of protein, fiber, and omega-3 fatty acids. Its role in appetite suppression is thought to be derived mostly from its fiber content.

The results of studies evaluating the ability of flaxseed to help control appetite have been mixed, but data suggests that it can be helpful in controlling hunger. Adding flaxseed to your diet can cause an increase in bowel movements each day, but it can also cause stomach discomfort and symptoms, including bloating, gas, and nausea.

These side effects increase with increased consumption of flaxseed. Flaxseed is available in oral capsule form as well as a loose, ground form in the health foods section of most stores. Healthy water intake has long been recommended as a core part of any weight control plan.

Adequate hydration is important to any human body but may play an especially important role in weight loss and appetite suppression in someone who is overweight.

One study shows that drinking an excess of 1. Water takes up space in the stomach, leading to increased satiety—especially before a meal. High water content in the body has the added benefit of increased internal energy expenditure, which can lead to weight loss as well. However, drinking too much water can raise blood pressure or cause temporary belly distension.

Typical intake recommendations range from 64 to 96 ounces daily. Check with your healthcare professional if you want to increase your intake beyond these recommendations. High-protein meals have been linked to a decrease in after-meal hunger and an increased feeling of fullness and satisfaction after a meal.

It is thought this effect is linked to an alteration in levels of hormones responsible for appetite regulation.

It is important to note that high protein diets, sometimes known as ketogenic diets, can lead to gastrointestinal discomfort and constipation, especially without adequate hydration. People with a history of kidney disease should speak with their prescriber before beginning a high-protein diet, as there is a higher risk of adverse events.

Eating a diet of high-fiber foods can lead to weight loss and make you feel full after meals. High-fiber foods include fresh fruit, like apples, and fiber-rich foods, such as oatmeal. One cup of oatmeal is a great source of fiber and contains about 4 grams of fiber.

Like fiber supplements, high-fiber foods can increase bowel movements and should be consumed with adequate amounts of water. The U. Department of Agriculture recommends eating 28 grams of fiber per day if you follow a 2,calorie diet. If you do not currently consume enough fiber, you should build up consumption slowly over time to avoid gastrointestinal discomfort.

Interactions : Until more research is done on the drug interactions with CLA, it is unclear how CLA interacts with prescription and nonprescription medications. Uses : Besides other amino acids in whey protein, tyrosine has had the following effects.

However, outcomes from the study above are limited because it was conducted in only eight females with obesity. Further studies with a larger sample size and a more diverse population are needed.

Dosage : The specific amount of tyrosine was not explicitly stated in the study, but the dose of the whey protein powder was 45 g dissolved in milliliters mL of semi-skim milk. More specifically, mL of the drink was given by mouth three times every five minutes.

Interactions : Caution should be taken if you take the following medications. Uses : Bitter orange Citrus aurantium contains a chemical compound called p-synephrine, which is known to have the following effects.

DHEA is a hormone produced by the adrenal glands and the liver. It serves as a precursor to sex hormones. DHEA dehydroepiandrosterone and 7-keto-DHEA are related but different. A limited number of studies suggests that 7-keto-DHEA , a form of DHEA, decreased body fat in people who are overweight or obese.

The mechanism behind the weight loss effect of 7-keto DHEA is due to its thermogenic effect, resulting in increased energy expenditure and increased metabolic rate.

The dose of 7-keto DHEA used in clinical trials is mg per day by mouth. Uses : One clinical study suggested DHEA favorably impacted body composition. Dosage : One study used mg per day of DHEA. Dosages may range between 25 mg and mg per day.

With the removal of ephedra from the market, bitter orange is commonly used as a substitute for ephedra due to the structural similarity between p-synephrine and ephedrine, the main component in the herb ephedra.

Despite the similarity in structure, p-synephrine acts differently from ephedra. Weight loss supplements can have side effects and interact with prescription drugs, over-the-counter drugs, and other dietary supplements.

Additionally, some products might be adulterated or tainted with prescription-drug ingredients. The best way to manage weight is to incorporate a healthy eating plan and moderate physical activity.

A healthy dietary pattern includes a variety of vegetables, fruits, and proteins and limits foods and beverages high in added sugars, sodium, and trans fats.

Stress causes increased cortisol a stress hormone secretion which promotes increased food intake, especially intake of sweet and nutrient-poor foods.

Some ways to manage stress include getting regular exercise , engaging in relaxing activities e. Stuby J, Gravestock I, Wolfram E, et al. Appetite-suppressing and satiety-increasing bioactive phytochemicals: A systematic review. Mathews NM. Prohibited contaminants in dietary supplements.
