Multivitamin
Daily multivitamin-mineral; follow label instructions
|
Extra vitamins and minerals help ensure people get the nutrition they needs, especially people on a weight-loss diet who are avoiding certain foods.
Diets that are low in total calories may not contain adequate amounts of various vitamins and minerals. For that reason, taking a multiple vitamin-mineral supplement is advocated by proponents of many types of weight-loss programs, and is essential when calorie intake will be less than 1,100 calories per day.

Pyruvate
6 to 10 grams daily combined with an exercise program
|
Combining exercise with pyruvate may help speed up your metabolism.
Pyruvate, a compound that occurs naturally in the body, might aid weight-loss efforts. A controlled trial found that pyruvate supplements (22 to 44 grams per day) enhanced weight loss and resulted in a greater reduction of body fat in overweight adults consuming a low-fat diet. Three controlled trials combining 6 to 10 grams per day of pyruvate with an exercise program reported greater effects on weight loss and body fat than that seen with a placebo plus the exercise program. Animal studies suggest that pyruvate supplementation leads to weight loss by increasing the resting metabolic rate.

5-HTP
Take under medical supervision: 600 to 900 mg daily for no more than 12 weeks
|
5-HTP has been shown to reduce appetite and to promote weight loss.
5-HTP (5-hydroxytryptophan), the precursor to the chemical messenger (neurotransmitter) serotonin, has been shown in three short-term controlled trials to reduce appetite and to promote weight loss. In one of these trials (a 12-week double-blind trial), overweight women who took 600 to 900 mg of 5-HTP per day lost significantly more weight than did women who received a placebo. In a double-blind trial with no dietary restrictions, obese people with type 2(non-insulin-dependent) who took 750 mg per dayof 5-HTP for two weeks significantly reduced their carbohydrate and fat intake. Average weight loss in two weeks was 4.6 pounds, compared with 0.2 pounds in the placebo group. This amount has not been established as a safe long-term treatment and should not be tried without a doctor's supervision; people taking antidepressants or other medications should be aware of potential drug interactions.

7-KETO
100 mg twice per day
|
7-KETO has been shown to promote weight loss in overweight people.
The ability of 7-KETO (3-acetyl-7-oxo-dehydroepiandrosterone), a substance related to DHEA, to promote weight loss in overweight people has been investigated in one double-blind trial. Participants in the trial were advised to exercise three times per week for 45 minutes and to eat an 1,800-calorie-per-day diet. Each person was given either a placebo or 100 mg of 7-KETO twice daily. After eight weeks, those receiving 7-KETO had lost more weight and lowered their percentage of body fat further compared with those taking a placebo. These results may have been due to increases in levels of a thyroid hormone (T3) that plays a major role in determining a person's metabolic rate, although the levels of T3 did not exceed the normal range.

Alpha-Lipoic Acid
Refer to label instructions
|
In one trial, obese people who supplemented with alpha-lipoic acid lost a statistically significant amount of weight, compared with a placebo. In another trial, supplementation with alpha-lipoic acid enhanced weight loss in overweight and obese women who were consuming a low-calorie diet.
In a double-blind trial, obese people who supplemented with alpha-lipoic acid (1,200 or 1,800 mg per day for 20 weeks) resulted in a statistically significant weight loss, compared with a placebo. The amount of weight lost was 6.1 pounds with 1,800 mg per day of alpha-lipoic acid, 3.3 pounds with 1,200 mg per day, and 2.1 pounds with placebo. The weight loss was due primarily to a loss of fat mass, as opposed to muscle mass. It is not clear how alpha-lipoic acid works, but it may work by increasing the conversion of fuel to energy in the body. In another double-blind trial, supplementation with alpha-lipoic acid (300 mg per day for 10 weeks) enhanced weight loss in overweight and obese women who were consuming a low-calorie diet. Women who received alpha-lipoic acid lost an average of 3.3 pounds more than women who received a placebo.

Borage Oil
5 grams (providing 890 mg of gamma-linolenic acid) per day
|
In one study, supplementing with borage oil helped reduce the amount of weight regained by obese people who had previously shed pounds.
In a double-blind study of obese people who had previously lost an average of about 66 pounds, supplementation with 5 grams of borage oil per day (providing 890 mg per day of gamma-linolenic acid) significantly reduced the average amount of weight regained over the next 12 months (4.8 pounds versus 19.3 pounds in the placebo group). It is believed that borage oil worked by correcting certain abnormalities of essential fatty acid metabolism that are common in people predisposed to obesity.

Calcium
800 mg daily
|
In a study of obese people following a low-calorie diet, those receiving a calcium supplement lost significantly more weight than those given a placebo.
Caution: Calcium supplements should be avoided by prostate cancer patients.
In a study of obese people consuming a low-calorie diet for 24 weeks, those receiving a calcium supplement (800 mg per day) lost significantly more weight than those given a placebo. Calcium was effective when provided either as a supplement, or in the form of dairy products. In a second study, however, the amount of weight loss resulting from calcium supplementation (1,000 mg per day) was small and not statistically significant. In that study, participants' typical diet contained more calcium than in the study in which calcium supplementation was more effective. Thus, it is possible that calcium supplementation enhances weight loss only when the diet is low in calcium.

Casein Protein
Refer to label instructions
|
Casein protein in milk may aid weight loss due to its effect on appetite, calorie burning, and body composition.
Casein, the main protein in milk, may aid weight loss due to its effect on appetite, calorie burning, and body composition. In a controlled trial, overweight women dieted for four months using a low-calorie diet that included three daily shakes made from either casein or soy protein. Both groups lost similar amounts of weight, with similar improvements in body composition, suggesting there was no difference in the weight-loss benefits of soy or casein protein. In another controlled trial, overweight men were given a low-calorie diet along with a weight training exercise plan for three months. Men who followed this plan and also took 1.5 grams per day of predigested casein protein per 2.2 lbs body weight lost a similar amount of weight as did men using a similar amount of whey protein along with the same diet and exercise plan. However, the men using casein protein gained more lean body mass and lost more body fat than the men using whey protein.

Cayenne
Add 6 to 10 grams to each meal
|
Incorporating cayenne pepper into the diet may promote weight loss by reducing hunger and calories consumed and increasing the calories the body burns.
Research has suggested that incorporating cayenne pepper into the diet may help people lose weight. Controlled studies report that adding 6 to 10 grams of cayenne to a meal or 28 grams to an entire day's diet reduces hunger after meals and reduces calories consumed during subsequent meals. Other controlled studies have reported that calorie burning by the body increases slightly when 10 grams of cayenne is added to a meal or 28 grams is added to an entire day's diet However, no studies have been done to see if regularly adding cayenne to the diet has any effect on weight loss.

Chitosan is a fiber-like substance that may reduce fat absorption. One study found it to be an effective weight-loss aid.
Chitosan is a fiber-like substance extracted from the shells of crustaceans such as shrimp and crab. Animal studies suggested that chitosan supplementation reduces fat absorption, but controlled human trials have found no impairment of fat absorption from supplementation with 2,700 mg of chitosan per day for seven days or 5,250 mg per day for four days. A double-blind study found that people taking 1,500 mg of chitosan three times per day during a weight-loss program lost significantly more weight than did people taking a placebo with the same program. Similar benefits were seen in another double-blind study that used 3,000 mg of chitosan per day. Other studies using smaller amounts of chitosan have reported no effects on weight loss.

Conjugated Linoleic Acid
3.2 to 4.2 grams daily
|
Though the evidence is conflicting, some studies have shown CLA to be effective at helping people lose body fat.
A double-blind trial found that exercising individuals taking 1,800 mg per day of conjugated linoleic acid (CLA) lost more body fat after 12 weeks than did a similar group taking a placebo. However, two other studies found that amounts of CLA from 0.7 to 3.0 grams per day did not affect body composition. Most double-blind trials have found that larger amounts of CLA, 3.2 to 4.2 grams per day, do reduce body fat; however, one double-blind study of experienced strength-training athletes reported no effect of 6 grams per day of CLA on body fat, muscle mass, or strength improvement.

Several trials have shown that fiber supplementation from a variety of sources accelerated weight loss in people who were following a low-calorie diet.
Fiber supplements are one way to add fiber to a weight-loss diet. Several trials have shown that supplementation with fiber from a variety of sources accelerated weight loss in people who were following a low-calorie diet. Other researchers found, however, that fiber supplements had no effect on body weight, even though they resulted in a reduction in food intake.

Green Tea
An extract supplying 270 mg of EGCG and 150 mg of caffeine per day
|
Green tea extract rich in polyphenols may support a weight-loss program by increasing energy expenditure or by inhibiting fat digestion.
Green tea extract rich in polyphenols (epigallocatechin gallate, or EGCG) may support a weight-loss program by increasing energy expenditure or by inhibiting the digestion of fat in the intestine. Healthy young men who took two green tea capsules (containing a total of 50 mg of caffeine and 90 mg of EGCG) three times a day burned significantly more calories and oxidized significantly more fat than those who took caffeine alone or a placebo. In a preliminary study of moderately obese individuals, administration of a specific green tea extract (AR25) resulted in a 4.6% reduction in average body weight after 12 weeks. The amount of green tea extract used in this study supplied daily 270 mg of EGCG and 150 mg of caffeine.
While caffeine is known to stimulate metabolism, it appears that other substances besides caffeine were responsible for at least part of the weight loss. Although the extract produced few side effects, one individual developed abnormal liver function tests during the study. In another study, consuming approximately 12 ounces of oolong tea (a semifermented version of green tea) daily for 12 weeks reduced waist circumference and the amount of body fat in a group of normal-weight to overweight men. However, in another study, 300 mg per day of EGCG was no more effective than a placebo for promoting weight loss in overweight postmenopausal women. Additional studies are needed to confirm the safety and effectiveness of green tea extracts for promoting weight loss.

HMB
3 grams per day or 17 mg per pound of body weight per day
|
HMB may improve muscle growth and overall body composition when combined with an exercise program in people who are not already highly trained athletes.
Biochemical and animal research show that HMB has a role in protein synthesis and might, therefore, improve muscle growth and overall body composition when given as a supplement. However, double-blind human research suggests that HMB may only be effective when combined with an exercise program in people who are not already highly trained athletes. Double-blind trials found no effect of 3 to 6 grams per day of HMB on body weight, body fat, or overall body composition in weight-training football players or other trained athletes. However, one double-blind study found that 3 grams per day of HMB increased the amount of body fat lost by 70-year old adults who were participating in a strength-training program for the first time. A double-blind study of young men with no strength-training experience reported greater improvements in muscle mass (but not in percentage body fat) when HMB was used in the amount of 17 mg per pound of body weight per day. However, another group of men in the same study given twice as much HMB did not experience any changes in body composition.

Yohimbe
Take under medical supervision: enough to supply 5 mg of yohimbine four times per day
|
Yohimbine, a chemical found in yohimbe bark, may help weight loss by raising metabolic rate, reducing appetite, and increasing fat burning.
The ability of yohimbine, a chemical found in yohimbe bark, to stimulate the nervous system, and to promote the release of fat from fat cells, has led to claims that it might help weight loss by raising metabolic rate, reducing appetite, or increase fat burning. Although a preliminary trial found yohimbine ineffective for weight loss, a double-blind study found that women taking 5 mg of yohimbine four times per day along with a weight-loss diet lost significantly more weight than those taking a placebo with the same diet after three weeks. However, a similar study using 18 mg per day of yohimbine for eight weeks reported no benefit to weight loss compared with a placebo. A double-blind study of men who were not dieting reported no effect of up to 43 mg per day of yohimbine on weight or body composition after six months. All of these studies used pure yohimbine; no study has tested the effects of yohimbe herb on weight loss.

Amylase Inhibitors
Refer to label instructions
|
Amylase inhibitors contain substances that prevent dietary carbohydrates from being absorbed by the body and may aid in weight loss.
Amylase inhibitors are also known as starch blockers because they contain substances that prevent dietary starches from being absorbed by the body. Starches are complex carbohydrates that cannot be absorbed unless they are first broken down by the digestive enzyme amylase and other, secondary, enzymes. When starch blockers were first developed years ago, they were found not to be potent enough to prevent the absorption of a significant amount of carbohydrate. Recently, highly concentrated starch blockers have been shown to be more effective, but no published human studies exist investigating their usefulness for weight loss.

Bitter Orange
Refer to label instructions
|
Bitter orange contains synephrine, which might promote weight loss.
Although historically used to stimulate appetite, bitter orange is frequently found in modern weight-loss formulas because synephrine is similar to the compound ephedrine, which is known to promote weight loss. In one study of 23 overweight adults, participants taking a daily intake of bitter orange (975 mg) combined with caffeine (525 mg) and St. John's wort (Hypericum perforatum, 900 mg) for six weeks lost significantly more body weight and fat than the control group. No adverse effects on heart rate or blood pressure were found. Bitter orange standardized to contain 4 to 6% synephrine had an anti-obesity effect in rats. However, the amount used to achieve this effect was accompanied by cardiovascular toxicity and mortality.

Blue-green algae, or spirulina, is a rich source of protein, vitamins, minerals, and essential fatty acids. It has been promoted as a weight-loss aid, but this claim has not been proven by research.
Blue-green algae, or spirulina, is a rich source of protein, vitamins, minerals, and essential fatty acids. In one double-blind trial, overweight people who took 2.8 grams of spirulina three times per day for four weeks experienced only small and statistically nonsignificant weight loss. Thus, although spirulina has been promoted as a weight-loss aid, the scientific evidence supporting its use for this purpose is weak.

Chromium
Refer to label instructions

A review of several studies concluded that supplementing with chromium picolinate may have a beneficial effect on weight loss.
The mineral chromium plays an essential role in the metabolism of carbohydrates and fats and in the action of insulin. Chromium, usually in a form called chromium picolinate, has been studied for its potential role in altering body composition. Chromium has primarily been studied in body builders, with conflicting results. In people trying to lose weight, a double-blind study found that 600 mcg per day of niacin-bound chromium helped some participants lose more fat and less muscle. However, three other double-blind trials have found no effect of chromium picolinate on weight loss, though in one of these trials lean body mass that was lost during a weight-loss diet was restored by continuing to supplement chromium after the diet. A recent comprehensive review combining the results of ten published and unpublished double-blind studies concluded that chromium picolinate supplementation may have a small beneficial effect on weight loss.

Egg protein may reduce appetite and help induce weight loss.
High-protein diets have been shown to help prevent and treat obesity. Researchers have found in a number of studies that, compared to eating carbohydrates in the morning, eating an egg breakfast is associated with appetite reduction and reduced calorie intake that could lead to weight loss in overweight and obese people. A mid-day egg meal has also been found to induce more of a sense of fullness than a carbohydrate-rich meal. How egg protein compares to whole eggs and to other protein supplements for reducing appetite and calorie consumption is not yet known.

Animal studies suggest that fucoxanthin, an antioxidant found naturally in some types of seaweed, might prevent the growth of fat tissue and reduce abdominal fat.
Fucoxanthin is a member of the carotenoid family, and is found naturally in some types of seaweed, such as wakame. Animal studies by one group of researchers suggest that fucoxanthin might prevent the growth of fat tissue and reduce abdominal fat. However, no studies have been done to see if this effect is achievable in humans, and one study found that fucoxanthin present in seaweed was absorbed quite poorly from the human digestive tract. Human research is needed to understand the value, if any, of fucoxanthin for helping with weight loss.

Garcinia cambogia
Refer to label instructions
|
HCA may aid in weight loss by suppressing appetite and by reducing the conversion of carbohydrates into stored fat.
(-)-Hydroxycitric acid (HCA), extracted from the rind of the Garcinia cambogia fruit grown in Southeast Asia, has a chemical composition similar to that of citric acid (the primary acid in oranges and other citrus fruits). Preliminary studies in animals suggest that HCA may be a useful weight-loss aid. HCA has been demonstrated in the laboratory (but not yet in clinical trials with people) to reduce the conversion of carbohydrates into stored fat by inhibiting certain enzyme processes. Animal research indicates that HCA suppresses appetite and induces weight loss. However, a double-blind trial found that people who took 1,500 mg per day of HCA while eating a low-calorie diet for 12 weeks lost no more weight than those taking a placebo. A double-blind trial of Garcinia cambogia (2.4 grams of dry extract, containing 50% hydroxycitric acid) found that the extract did not increase energy expenditure; it was therefore concluded that this extract showed little potential for the treatment of obesity at this amount. Nonetheless, another double-blind trial found that using the same amount of Garciniacambogia extract significantly improved the results of a weight-loss diet, even though the amount of food intake was not affected.

Green Coffee Extract
Extract providing 400 to 450 mg of chlorogenic acids per day
|
Some research has suggested that green coffee extracts taken as supplements or in food may support weight loss.
Animal research suggests that green coffee extract and its major component, chlorogenic acid, may help with weight loss and reducing abdominal fat. An uncontrolled human study found that people who drank 750 ml per day of coffee containing green coffee bean constituents for four weeks ate fewer calories and lost weight. In a controlled study, overweight people who drank a coffee beverage containing green coffee extract (providing 400 to 450 mg of chlorogenic acids per day) for 12 weeks lost an average of about 12 pounds and 3.6% body fat compared to less than 4 pounds and an insignificant amount of body fat lost by people who drank a similar amount of coffee without added green coffee extracts. Another controlled study reported a statistically significant 11 pound weight loss after 60 days when overweight people took 400 mg per day of green coffee extracts (providing 180 mg of chlorogenic acids per day), compared to about a five pound loss in people taking a placebo. The green coffee extracts group also significantly raised their ratio of lean body tissue to body fat compared to the control group. However, since these studies lasted only 12 weeks or less, more research is needed to determine if green coffee extract can help people accomplish long-term weight loss. In addition, at least one human study supporting green coffee extract's effect on weight loss has been retracted due to methodological problems, raising suspicion about research relating to green coffee extract and weight loss.

The herb guaraná contains caffeine and the closely related alkaloids theobromine and theophylline; these compounds may curb appetite and increase weight loss. Caffeine's effects are well known and include central nervous system stimulation, increased metabolic rate, and a mild diuretic effect. In a double-blind trial, 200 mg per day of caffeine was, however, no more effective than a placebo in promoting weight loss. Because of concerns about potential adverse effects, many doctors do not advocate using caffeine or caffeine-like substances to reduce weight.

Coupled with exercise in a double-blind trial, a combination of guggul, phosphate salts, hydroxycitrate, and tyrosine has been shown to improve mood with a slight tendency to improve weight loss in overweight adults. Daily recommendations for guggul are typically based on the amount of guggulsterones in the extract. A common intake of guggulsterones is 25 mg three times per day. Most guggul extracts contain 5 to 10% guggulsterones and can be taken daily for 12 to 24 weeks.

The amino acid L-carnitine is thought to be potentially helpful for weight loss because of its role in fat metabolism. In a preliminary study of overweight adolescents participating in a diet and exercise program, those who took 1,000mg of L-carnitine per day for three months lost significantly more weight than those who took a placebo. A weakness of this trial, however, was the fact that the average starting body weight differed considerably between the two groups. A double-blind trial found that adding 4,000 mg of L-carnitine per day to an exercise program did not result in weight loss in overweight women.

Animal research and preliminary human reports suggest that serotonin precursors such as L-tryptophan might help control appetite and promote weight loss.
Animal research and preliminary human reports suggest that serotonin precursors such as L-tryptophan or 5-HTP (5-hydroxytryptophan) might help control appetite and promote weight loss. In a controlled study, increasing L-tryptophan supplementation one hour before a meal from 1 gram to 2 grams to three grams resulted in progressively fewer calories and carbohydrates being consumed during the meal at the higher L-tryptophan dosages. While this effect might lead to weight loss over time, a small double-blind trial did not find a significant benefit from taking 1 gram of L-tryptophan before each meal as part of a six-week weight loss program. Weight-loss diets result in lower L-tryptophan and serotonin levels in women, which could theoretically trigger cravings and make dieting more difficult. More research is needed to determine whether L-tryptophan might improve the results of a long-term weight loss diet.

Pea protein is rich in branched-chain amino acids that have specifically been found to aid in weight loss and improve body composition. Pea protein may also affect weight loss by reducing appetite. Compared to whey protein and milk protein, 15 grams of pea protein was found to be better at inducing satiety (a sense of fullness) in overweight people. In a study looking at protein supplements and food consumption in healthy weight men, 20 grams of pea protein was as effective as casein protein and better than whey and egg protein at increasing fullness and reducing calorie intake when taken 30 minutes before a meal. None of the protein supplements reduced appetite or calorie intake when taken immediately before a meal.

Soy appears to have several effects on the body that might help with weight loss.
Animal and human studies have suggested that when soy is used as a source of dietary protein, it may have several biological effects on the body that might help with weight loss. A preliminary study found that people trying to lose weight using a meal-replacement formula containing soy protein lost more weight than a group not using any formula. However, controlled studies comparing soy protein with other protein sources in weight-loss diets have not found any advantage of soy. When soy protein is used for other health benefits, typical daily intake is 20 grams per day or more.

Whey protein may aid weight loss due to its appetite-suppressing effect.
Whey protein may aid weight loss due to its effect on appetite. In a preliminary study, people were given 48 grams of either whey protein or milk protein (casein). Whey consumption resulted in more hunger satisfaction and reduced the amount of food eaten 90 minutes later compared with casein consumption. However, a double-blind study found that men taking 1.5 grams per 2.2 lbs body weight per day of whey protein for 12 weeks along with a low-calorie diet and a strength training exercise program lost the same amount of weight and body fat as did a control group that followed a similar program, but took a casein supplement instead of whey protein.
