How to Lose Weight Quickly and Safely

Nutrisystem has been helping millions of people in achieving their weight loss goals. In addition, it also helps those who want to keep control of their weight and health. The portion-controlled diet program is very simple and easy to follow. Nutrisystem program has several plans as listed below. All plans comes with Turbo 13 kit which is the latest addition for Nutrisystem plans for women has three sub plans namely Basic, Core and Uniquely Yours.

In basic plan, foods are preselected for you. In Core plan, you can choose your own food and you also have free access to dietitians and counselors. You also get free access to dietitians and counselors. Fitness and nutritional needs vary for both men and women. Considering this fact, NutriSystem has designed individual plans for men and women separately. This helps the men in losing weight healthily without facing those hunger pangs. The pharmacodynamics of AAS are unlike peptide hormones.

However, as fat-soluble hormones, AAS are membrane-permeable and influence the nucleus of cells by direct action. The pharmacodynamic action of AAS begin when the exogenous hormone penetrates the membrane of the target cell and binds to an androgen receptor AR located in the cytoplasm of that cell.

From there, the compound hormone-receptor diffuses into the nucleus, where it either alters the expression of genes [] or activates processes that send signals to other parts of the cell. The effect of AAS on muscle mass is caused in at least two ways: It has been hypothesized that this reduction in muscle breakdown may occur through AAS inhibiting the action of other steroid hormones called glucocorticoids that promote the breakdown of muscles.

As their name suggests, AAS have two different, but overlapping, types of effects: Some examples of the anabolic effects of these hormones are increased protein synthesis from amino acids , increased appetite, increased bone remodeling and growth, and stimulation of bone marrow , which increases the production of red blood cells.

Through a number of mechanisms AAS stimulate the formation of muscle cells and hence cause an increase in the size of skeletal muscles , leading to increased strength. The androgenic effects of AAS are numerous. Depending on the length of use, the side effects of the steroid can be irreversible. Processes affected include pubertal growth, sebaceous gland oil production, and sexuality especially in fetal development.

Some examples of virilizing effects are growth of the clitoris in females and the penis in male children the adult penis size does not change due to steroids [ medical citation needed ] , increased vocal cord size, increased libido , suppression of natural sex hormones , and impaired production of sperm. Men may develop an enlargement of breast tissue, known as gynecomastia, testicular atrophy, and a reduced sperm count.

Compounds with a high ratio of androgenic to an anabolic effects are the drug of choice in androgen-replacement therapy e. This disassociation is less marked in humans, where all AAS have significant androgenic effects.

A commonly used protocol for determining the androgenic: The VP weight is an indicator of the androgenic effect, while the LA weight is an indicator of the anabolic effect. Two or more batches of rats are castrated and given no treatment and respectively some AAS of interest.

Animal studies also found that fat mass was reduced, but most studies in humans failed to elucidate significant fat mass decrements. The effects on lean body mass have been shown to be dose-dependent. Both muscle hypertrophy and the formation of new muscle fibers have been observed. The hydration of lean mass remains unaffected by AAS use, although small increments of blood volume cannot be ruled out.

The upper region of the body thorax, neck, shoulders, and upper arm seems to be more susceptible for AAS than other body regions because of predominance of ARs in the upper body. After drug withdrawal, the effects fade away slowly, but may persist for more than 6—12 weeks after cessation of AAS use. Overall, the exercise where the most significant improvements were observed is the bench press. The measurement of the dissociation between anabolic and androgenic effects among AAS is based largely on a simple although arguably unsophisticated and outdated model involving rat tissue bioassays.

The intracellular metabolism theory explains how and why remarkable dissociation between anabolic and androgenic effects can occur despite the fact that these effects are mediated through the same signaling receptor, and of course why dissociation is invariably incomplete. An animal study found that two different kinds of androgen response elements could differentially respond to testosterone and DHT upon activation of the AR. Changes in endogenous testosterone levels may also contribute to differences in myotrophic—androgenic ratio between testosterone and synthetic AAS.

Testosterone can be metabolized by aromatase into estradiol , and many other AAS can be metabolized into their corresponding estrogenic metabolites as well. The major effect of estrogenicity is gynecomastia woman-like breasts.

AAS are androstane or estrane steroids. As well as others such as 1-dehydrogenation e. The most commonly employed human physiological specimen for detecting AAS usage is urine, although both blood and hair have been investigated for this purpose.

The AAS, whether of endogenous or exogenous origin, are subject to extensive hepatic biotransformation by a variety of enzymatic pathways. The primary urinary metabolites may be detectable for up to 30 days after the last use, depending on the specific agent, dose and route of administration.

A number of the drugs have common metabolic pathways, and their excretion profiles may overlap those of the endogenous steroids, making interpretation of testing results a very significant challenge to the analytical chemist.

Methods for detection of the substances or their excretion products in urine specimens usually involve gas chromatography—mass spectrometry or liquid chromatography-mass spectrometry. The use of gonadal steroids pre-dates their identification and isolation. Medical use of testicle extract began in the late 19th century while its effects on strength were still being studied.

In the s, it was already known that the testes contain a more powerful androgen than androstenone , and three groups of scientists, funded by competing pharmaceutical companies in the Netherlands, Germany, and Switzerland, raced to isolate it. The chemical synthesis of testosterone was achieved in August that year, when Butenandt and G.

Wettstein, announced a patent application in a paper "On the Artificial Preparation of the Testicular Hormone Testosterone Androstenoneol.

Clinical trials on humans, involving either oral doses of methyltestosterone or injections of testosterone propionate , began as early as Kennedy was administered steroids both before and during his presidency.

The development of muscle-building properties of testosterone was pursued in the s, in the Soviet Union and in Eastern Bloc countries such as East Germany, where steroid programs were used to enhance the performance of Olympic and other amateur weight lifters.

In response to the success of Russian weightlifters, the U. The new steroid was approved for use in the U. It was most commonly administered to burn victims and the elderly. The drug's off-label users were mostly bodybuilders and weight lifters. Although Ziegler prescribed only small doses to athletes, he soon discovered that those having abused Dianabol suffered from enlarged prostates and atrophied testes.

Three major ideas governed modifications of testosterone into a multitude of AAS: Androgens were discovered in the s and were characterized as having effects described as androgenic i. Although anabolic steroid was originally intended to specifically describe testosterone-derived steroids with a marked dissociation of anabolic and androgenic effect, it is applied today indiscriminately to all steroids with AR agonism-based anabolic effects regardless of their androgenic potency, including even non-synthetic steroids like testosterone itself.

The legal status of AAS varies from country to country: Unlawful distribution or possession with intent to distribute AAS as a first offense is punished by up to ten years in prison. Those guilty of buying or selling AAS in Canada can be imprisoned for up to 18 months. In Canada, researchers have concluded that steroid use among student athletes is extremely widespread. A study conducted in by the Canadian Centre for Drug-Free Sport found that nearly 83, Canadians between the ages of 11 and 18 use steroids.

AAS are readily available without a prescription in some countries such as Mexico and Thailand. The history of the U. The same act also introduced more stringent controls with higher criminal penalties for offenses involving the illegal distribution of AAS and human growth hormone. By the early s, after AAS were scheduled in the U. In the Controlled Substances Act, AAS are defined to be any drug or hormonal substance chemically and pharmacologically related to testosterone other than estrogens , progestins , and corticosteroids that promote muscle growth.

The act was amended by the Anabolic Steroid Control Act of , which added prohormones to the list of controlled substances , with effect from January 20, In the United Kingdom, AAS are classified as class C drugs for their illegal abuse potential, which puts them in the same class as benzodiazepines.

Part 1 drugs are subject to full import and export controls with possession being an offence without an appropriate prescription.

There is no restriction on the possession when it is part of a medicinal product. Part 2 drugs require a Home Office licence for importation and export unless the substance is in the form of a medicinal product and is for self-administration by a person. Many other countries have similar legislation prohibiting AAS in sports including Denmark, [] France, [] the Netherlands [] and Sweden. United States federal law enforcement officials have expressed concern about AAS use by police officers.

It's not that we set out to target cops, but when we're in the middle of an active investigation into steroids, there have been quite a few cases that have led back to police officers," says Lawrence Payne, a spokesman for the United States Drug Enforcement Administration.

Following the murder-suicide of Chris Benoit in , the Oversight and Government Reform Committee investigated steroid usage in the wrestling industry. The documents stated that 75 wrestlers—roughly 40 percent—had tested positive for drug use since , most commonly for steroids. AAS are frequently produced in pharmaceutical laboratories, but, in nations where stricter laws are present, they are also produced in small home-made underground laboratories, usually from raw substances imported from abroad.

As with most significant smuggling operations, organized crime is involved. In the late s, the worldwide trade in illicit AAS increased significantly, and authorities announced record captures on three continents. In , Finnish authorities announced a record seizure of A year later, the DEA seized In the first three months of , Australian customs reported a record seizures of AAS shipments.

Illegal AAS are sometimes sold at gyms and competitions, and through the mail, but may also be obtained through pharmacists, veterinarians, and physicians. AAS, alone and in combination with progestogens , have been studied as potential male hormonal contraceptives. From Wikipedia, the free encyclopedia. This article is about androgens as medications.

Or can tomatoes, cukes, etc. Also, plain or with some sort of dressing? How many turbo shakes can you have per week… and when can they be consumed? Thanks in advance …. Hi Tami — Thanks for stopping by and taking the time to comment! I always add extra veggies to my greens and have found the only thing you really need to watch out for is the salad dressing.

But for me, cucumbers, tomatoes, etc. I usually have my TurboShake midday — around 2: That said, I would definitely suggest using the Nutrisystem counseling service for full clarification, though — especially for questions 2 and 3.

Best of luck if you decide to try the full program! I wanted to say that this article is nicely written and included almost all the vital info I needed. Thanks for the review. I second your recommendation for Nutrisystem. Their service helped me significantly a few years ago.

Hoping for the same results! Hi Maria — thanks for commenting! Hope it goes well again if you decide to give it another try. Have you found that Nutrisystem is a good way for keeping the weight off over the long term? How long do you really have to be on Nutrisystem before you starting seeing results? Just finished month 1 and lost about 9 pounds! This post could not be written any better!

Reading this post reminds me of my good old room mate! He was always trying new weight loss products. I will forward this page to him. Fairly certain he will have a good read. Thank you for sharing! I just read this well written post. I have a handicapped daughter who has gained so much weight. We have tried everything with very little success. After taking to her doctors we decided to give NS a try. She started the program on February 16, She is loving the food and the program. She has already dropped three pounds.

Her beginning weight was So she has a long way to go. But the support and your post will definitely help her obtain her goals for healthier lifestyle. We will keep you informed on her progress. Thank you so much. Hi Shirley — What an inspirational story — really hoping she has success! Thanks for keeping us posted, and wishing your daughter all the best. I suppose its ok to use some of your ideas!! I have been on Nutrisystem for about 5 weeks now. I lost 15 pounds the first month and have been following it to a T.

The food tastes fine and it is very easy to just grab something pop it in the microwave if necessary and go. I have been using My Fitness Pal to track my food and am eating about calories a day. The first week was really tough and I had a hard time, but I stuck to it.

Now I m satisfied and use to it. Planning on finishing up the second month and then on the 3rd month working in more home cooked meals and tracking to stay at the same calorie level. Then will switch over to the auto ship of Turbo shakes for my 4th month. I have about 40 pounds to lose and feel like I am making some good headway with the Nutrisystem plan. Good job on the review, very well written.

Wow, nice job Carolyn! Thanks for sharing your story, and best of luck with the rest of your diet. I was very happy to find this website. Just wanted to thank for your time for this wonderful read, and inspirational review!! Hi Kelly — sorry to hear that! Have you tried connecting with the Nutrisystem counseling service?

We had to take Nutrisystem program for 8 weeks because we got it at a discount thru our insurance company. My goal was to loose 30 lbs. At the end of the 8 weeks I had lost only 3 lbs. We did not care for the cardboard like food and did not get anywhere close to our goals. This program obviously works for lots of folks, but not for us.

We did go to the Naturally Slim program and in 8 weeks I lost Naturally Slim is based on not what you eat but when and how you eat and you eat your own real food and got real results. We will stay with our new habits learned with Naturally Slim and will not have any good words from our Nutrisystem experience. Hi John — thanks for sharing your experience. Thanks so much for sharing your story. It was encouraging and helpful.

I am only on my second day of Lean 13 and after comparing the Turbo Shakes with the protein powder I was using before, I noticed that mine was lower in calories, fat, sugar, and carbs and higher in protein by quite a lot.

Thanks again for your review! Hi Peggy — I think you should be fine using your own protein shake. Just to be safe you may want to talk to a Nutrisystem counselor, and they can let you know for sure.

The biggest issue would probably be the calorie count of your shake vs. Best of luck with your two weeks. I made some raspberry coffee and chilled it. Thought that might be a nice tip for someone else. Just finished day 1 of the Turbo Takeoff… I was down 2 lbs this morning!!! Yay… only 58 more lbs to go!!! I am so determined and my mind is in the right place to really do this, this time..

I am very excited for the results.. I know i will be on the program for a few months but, I really feel like I need the structure of this program right now. I have been feeling a lot of emotions from having gone through breast cancer and several surgeries the last 3 years… I just kinda let myself go… but, I am so ready for this change!!!

Thanks for sharing, Lynn! Best of luck with reaching your goals! Very thorough review…thanks for making the decision easier! I just signed up for my first order. Went with the Core, and really hoping to least a good 20 pounds. Just finished month 1. Does this stuff really work?

Thanks for the comment, Heather…It definitely works when you follow the program correctly. Best of luck if you decide to try it! First, take the time to put the food on a plate like you would normally eat. Focus on the journey. Take the time to praise yourself for the positive change. I started on Nutrisystem exactly 2 months ago with a week lapse. I only wish I had started months before. Question first great info as I really need something kind of no Brainerd and ready. How long in your experience would you say orders take to turn around?

I am currently out of town but want to have the product arrive day if or day after returning so I can hit the ground running. Thanks ahead for any info. Hi Deb — Thanks for visiting. If I remember correctly, the last time I ordered it only took 3 or 4 days to get my shipment. Thanks for the review! This was helpful in determining which program to start! I also appreciate your thoroughness and videos. I hope to get fit during my weight loss journey and obtain my goal by next year.

Hi Rose — Glad you liked it, and best of luck with your weight loss journey! Is it possible to melt away one to two pounds of stubborn body fat every single day? It sounds insane, but according to the scientific proof — and the thousands who have already done it themselves using this secret — the answer is YES.

I have tried every diet on the market. This was my last resort. In fact, I have to remind myself to get everything in. My doctor is on the program, her husband and son! Notify me of new posts by email.
