While no university studies support the theory that varying caloric intake aids weight loss, the high quality of the food and the relatively large portion sizes have been praised by Health magazine, Dr.

Phil and The New York Times. Some plan users have complained of a lack of choices and menu flexibility compared to other plans, but a company spokesman says they offer more than entrees and can make substitutions to accommodate allergies and food preferences. It's a reasonable price for well-made food with slightly faster average weight loss than with Jenny Craig. This meal-delivery service, endorsed by Marie Osmond and Dan Marino, emphasizes foods with a low glycemic index. The underlying premise is that controlling blood sugar levels leads to weight loss.

The heat-and-eat prepared meals and snacks contain roughly 55 percent "good" carbs, 25 percent protein, and 20 percent fats; like Jenny Craig, you add fruits, vegetables and dairy. Support is available through phone counseling and online chat rooms. There's plenty of research showing that following a diet of 1, to 1, calories a day, such as Nutrisystem, can cause weight loss. For example, a study by the Obesity Research Center at St.

Luke's Roosevelt Hospital in New York found that postmenopausal women who followed a 1,calorie plan for 16 weeks lost an average of 21 pounds. For a meal-delivery diet system, Nutrisystem is more economical than Jenny Craig. Although today's program is not as stringent as the original liquid fast Medifast launched decades ago, the low-fat, relatively low-carb plan is designed to bring about rapid weight loss by coaxing your body into a "fat-burning state" known as ketosis.

The 70 meal replacement choices include shakes, bars, soups, pudding, oatmeal, chili, pretzel sticks, cheese puffs, and scrambled eggs. If you can stick with it, a diet of 1, calories a day can certainly induce rapid weight loss. A common concern with such low-calorie diets is that you'll quickly regain the weight, but in a small clinical trial recently published in the journal Experimental Biology , after 10 months, only about one in five people regained all the weight they had lost.

The intent is to increase muscle, increase body weight, improve athletic performance, and for some sports, to simultaneously decrease percent body fat so as to create better muscle definition. Among the most widely used are high protein drinks , branched-chain amino acids BCAA , glutamine , arginine , essential fatty acids , creatine , HMB , [1] and weight loss products.

While many bodybuilding supplements are also consumed by the general public the frequency of use will differ when used specifically by bodybuilders. Athletes in ancient Greece were advised to consume large quantities of meat and wine. A number of herbal concoctions and tonics have been used by strong men and athletes since ancient times across cultures to try to increase their strength and stamina.

Later, bodybuilder Earle Liederman advocated the use of "beef juice" or "beef extract" basically, consomme as a way to enhance muscle recovery. In s with recreational and competitive bodybuilding becoming increasingly popular Irvin P.

Johnson began to popularize and market egg-based protein powders marketed specifically at bodybuilders and physical athletes. The s and s marked a dramatic increase in the growth of the bodybuilding supplement industry, fueled by widespread use of modern marketing techniques and a marked increase in recreational bodybuilding.

Under DSHEA, responsibility for determining the safety of the dietary supplements changed from government to the manufacturer and supplements no longer required approval from the U. Since that time manufacturers did not have to provide FDA with the evidence to substantiate safety or effectiveness unless a new dietary ingredient was added.

It is widely believed that the DSHEA further consolidated the position of the supplement industry and lead to additional product sales. While many of the claims are based on scientifically based physiological or biochemical processes, their use in bodybuilding parlance is often heavily colored by bodybuilding lore and industry marketing and as such may deviate considerably from traditional scientific usages of the terms.

In addition, ingredients listed have been found at times to be different from the contents. In , Consumer Reports reported unsafe levels of arsenic, cadmium, lead and mercury in several of the protein powders that were tested.

In the United States, the manufacturers of dietary supplements do not need to provide the Food and Drug Administration with evidence of product safety prior to marketing. In a CBC investigative report found that protein spiking the addition of amino acid filler to manipulate analysis was not uncommon, [12] however many of the companies involved challenged these claims. The US FDA reports 50, health problems a year due to dietary supplements [14] and these often involve bodybuilding supplements.

In addition to being potentially harmful, some have argued that there is little evidence to indicate any benefit to using bodybuilding protein or amino acid supplements. The muscle mass increase was statistically significant but modest - averaging 0. Bodybuilders may supplement their diets with protein for reasons of convenience, lower cost relative to meat and fish products , ease of preparation, and to avoid the concurrent consumption of carbohydrates and fats.

In addition, some argue that bodybuilders, by virtue of their unique training and goals, require higher-than-average quantities of protein to support maximal muscle growth; [19] [20] [21] [22] [23] [24] [25] however there is no scientific consensus for bodybuilders to consume more protein than the recommended dietary allowance. Protein powders are the most popular and may have flavoring added for palatability.

The powder is usually mixed with water, milk or fruit juice and is generally consumed immediately before and after exercising or in place of a meal. The sources of protein are as follows and differ in protein quality depending on their amino acid profile and digestibility:.

Some nutritionists claim that osteoporosis may occur from excessive protein intake because protein can put pressure on the kidneys and lead to bone loss due to calcium leaching. Some bodybuilders believe that amino acid supplements may benefit muscle development, but consumption of such supplements is unnecessary in a diet that already includes adequate protein intake.

Prohormones are precursors to hormones and are most typically sold to bodybuilders as a precursor to the natural hormone testosterone. This conversion requires naturally occurring enzymes in the body. Side effects are not uncommon, as prohormones can also convert further into DHT and estrogen. To deal with this, many supplements also have aromatase inhibitors and DHT blockers such as chrysin and 4-androstene-3,6,trione. To date most prohormone products have not been thoroughly studied, and the health effects of prolonged use are unknown.

Although initially available over the counter, their purchase was made illegal without a prescription in the US in , and they hold similar status in many other countries. They remain legal, however, in the United Kingdom and the wider European Union. Their use is prohibited by most sporting bodies. Creatine is an organic acid naturally occurring in the body that supplies energy to muscle cells for short bursts of energy as required in lifting weights via creatine phosphate replenishment of ATP.

A number of scientific studies have shown that creatine can improve strength, [32] energy, [33] muscle mass, and recovery times.

In addition, recent studies have also shown that creatine improves brain function. Creatine increases what is known as cell volumization by drawing water into muscle cells, making them larger. Creatine is sold in a variety of forms, including creatine monohydrate and creatine ethyl ester , amongst others. Though all types of creatine are sold for the same purposes, there are subtle differences between them, such as price and necessary dosage.

Creatine monohydrate is regarded as a necessity by most bodybuilders. Creatine monohydrate is the most cost-effective dietary supplement in terms of muscle size and strength gains. This can be accomplished by mixing powdered creatine with grape juice, lemonade, or many high glycemic index drinks. Some studies have suggested that consumption of creatine with protein and carbohydrates can have a greater effect than creatine combined with either protein or carbohydrates alone.

The inhibition of exercise-induced skeletal muscle damage by HMB is affected by the time that it is used relative to exercise. Meal replacement products MRPs are either pre-packaged powdered drink mixes or edible bars designed to replace prepared meals. MRPs are generally high in protein, low in fat, have a low to moderate amount of carbohydrates, and contain a wide array of vitamins and minerals. Some MRPs also contain flax oil powder as a source of essential fatty acids.

MRPs can also contain other ingredients, such as creatine monohydrate , glutamine peptides, L-glutamine , calcium alpha-ketoglutarate , additional amino acids, lactoferrin , conjugated linoleic acid , and medium-chain triglycerides. A sub-class of MRPs is colloquially known as "weight gainers", which are meal replacement products with a higher carbohydrate: Whereas a MRP will typically have a 0. A thermogenic is a broad term for any supplement that the manufacturer claims will cause thermogenesis , resulting in increased body temperature, increased metabolic rate, and consequently an increased rate in the burning of body fat and weight loss.

Until almost every product found in this supplement category comprised the " ECA stack ": However, on February 6, the Food and Drug Administration FDA banned the sale of ephedra and its alkaloid , ephedrine, for use in weight loss formulas. Several manufacturers replaced the ephedra component of the "ECA" stack with bitter orange or citrus aurantium containing synephrine instead of the ephedrine.
