The suggestedhome cooked meals and snacks include:

• Roast chicken stir fry, Mozzarella string cheese, cheese and spinach omelet with avocado and salsa, Atkins advantage vanilla shake, and an Atkins frozen chicken & broccoli alfredo alongside a salad.

One does not have to purchase the Atkins Diet brand foods however;one can make their own foods based off the principles of the diet. The link provided has a list of the highest rated diets for weight loss.

The Mayo Clinic has also outlined some possible side effects form this diet which includes:

         • Fatigue, weakness, and headache.

         • Constipation and dizziness.

They also mention the following potential concerns:

“some very low carb diets restrict carbohydrates so much that the result in nutritional deficiencies or insufficient fiber, which can cause such health problems as constipation, diarrhea, and nausea”

Due to the extreme restriction of carbohydrates, it can place the body in a state of ketosis, where it switches from glucose as primary fuel source to instead fat. This has not been studied long-term, but people often mention symptoms while in this state.

EDITOR’S TIP: Combine this diet with a proven meal replacement such as 18 Shake for better results.

Atkins Diet Quality of Ingredients

If one does not purchase the brands prepackaged foods the foods one will eat are mostly high protein, moderate fat, and low carbohydrates that are mostly sourcedfromvegetables. Protein is known to help with appetitesuppression, but limiting oneself to either 20 net grams or 40 net grams of carbohydrates can be difficult.

Eating whole natural foods is a good step to help with weight loss, but the ratio of macronutrients can be difficult to continue. Ne study performed by the University of Pennsylvania confirmed this issue:

“Adherence was poor and attrition was high”

They also rated it against a lower calorie diet and found:

“differences were not significant at one year”

Any weight loss benefits were minimal, and with continued use for a year it was shown to not be any better than a basic low calorie approach to weight loss.  Our experts have rated diet plans and ranked them in a comprehensive top 10 listfeatured here.

The Price and Quality of Atkins Diet

There are books available as well as pre-packaged foods which are optional. Thebasics of the diet can be learned about without having to make a purchase however. Most of the information on how to start and sustain the diet isfeatured on many free websites.

A study by Forbes magazine did show that the sample menu provided by the company made it one of the most expensive in terms of overall cost of ingredientshowever.

There have also been issues having to do with side effects. The AMA council on Foods and Nutrition found:

“Atkins’ food plan can increase the dieters risk if heart disease”

Another studyby the University of California found that most of the weight people lost was only water weight and not actual fat. Therefore, this means that because of the reduction of carbohydrates, any quick weight loss will return as soon as one reintroduces carbohydrates.

Business of Atkins Diet

The name of the company is Atkins Nutritional, Inc. They can be reached via the following:

Phone Number: (800)

The creator of the diet was a cardiologist named Robert Atkins. His field of medicine had to do with treating heart conditions, not for nutrition and weight loss. He actually sufferedfrom a heart attack, which are exactly what those who criticized the diet said were the issue with the Atkins Diet.

Studies have shown that a diet like this can be potentially dangerous to heart health.  The link cited here has a comprehensive list of the best weight loss diets.

Customer Opinions of Atkins Diet

Here are some select quotes from those who have tried the Atkins Diet:

“I feltlike crap for the whole 6 months I was on Atkins”

“I was so sick of meat and chicken that I actually would look at my plate and get sick”

“The Atkins Diet give you an overwhelming craving for cookies, cakes, fruits, and other sweet carbohydrates”

“The diet is so hard to keep up with”

The most common complaint was that maintaining the diet was difficult, and that people were unable to keep eating the same kinds of foods. Many had severe cravings for more carbohydrates.

There were some success stories with people losing weight, but this quickly returned as soon as carbohydrates were eaten. This is likely due to the added water weight from these kinds of foods.

Certainpeoplebecame nauseous and unable to continue using the diet. Some expressed concern that though they were not hungry, they also didn’t want to continue using the diet and that the cravings for carbohydrates can become extreme. The link provided here has a list of the top 10 diet plans.

Conclusion - Does Atkins DietWork?

The Atkins Diet emphasizes a strict carbohydrate reduction and instead allows for high amounts of protein and some healthy fats. This diet started the low carbohydrate fad diets, and studies have shown it to be potentially dangerous. There are concerns by the American Heart Association due to the potential damaging effects on the heart. Users have also mentioned it’s difficult to sustain, and that any weight loss is lost as soon as one eats carbohydrates again. It can be extremely difficult to eat the same basic foods, and people add how it made them no longer want to eat due to nausea. Studies have shown that long-term use has a similar weight loss effect to a standard low calorie diet.

I have tried this diet. It does make you feel full. It does take some weight off. But there is a severe disadvantage. The Atkins Diet gives you an overwhelming craving for cookies, cakes, fruits, and other sweet carbohydrates! Where as many other diets drive you insane with hunger because of portion control, the Atkins Diet torments you with a tremendous craving for sweet carbohydrates you never had before going on it!

I have read the book and I have lost the weight soooo easily. I understand now, my consciouness has been raised...FAT METABOLISM ROCKS! A diet of sugar and flour will undoubtedly shorten your life as will a low calorie/high exercise diet. If you can't get the ketosis happening then check your carbs are no more than 10 grams and eat a bit more fat/protein. This should kickstart fat mobilisation as recommended by Dr Atkins, may he rest in peace. If the good doctor can restrict 10 obese individuals to a high fat diet over a six week period which caused every one of them to LOSE weight, then you can to. DO IT.

I did Atkins about 6 years ago and dropped 30 lbs right away. I'm on my 5th day of induction and haven't lost any weight. I went into ketosis within a couple of days. A bit frustrated..plus this time I'm exercising. What is going on?

posted Jun 4th, 2008 9:01 pm


Actually, it's 130g of GLUCOSE a day that is needed, not carbs. The body is quite capable of making enough carbs to keep everything running through a process called gluconeogenesis. If not, everyone who is doing low carb would be chronically hypoglycemic and that's not the case.

I am back to Atkins - This time I am sticking to it - for life probably. I have always had good results but you are right - the minute you eat what you are not supposed to eat anyway, sugar, anything white, you gain it right back. You have to be soooo careful.

I felt like crap for the whole 6 months I was on Atkins!! I lost weight, but what good is losing weight, if you are a wreck? My hair started falling out, at first I had no energy and then out of nowhere, I couldn't sleep at all. After about 5 months, I had no desire to eat anything. 6 months on Atkins, made me a vegetarian for two years. The sight or thought of meat, made me want to puke.

posted May 21st, 2008 9:56 am


At first, I loved this diet. You can eat a lot and still lose weight. After 3 months, I had lost 30 pounds. However, by this time I was so sick of meat and chicken that I actually would look at my plate and get sick. it got to where I didn't want to eat at all which is not healthy. Great diet if you can stick to it.

please i dont think you heve read the program correctly, you can have fruits and grains, just no in the first two stages, what is so hard to understand about that. you can use the diet as a start you add in the little things in portion control, that is all it takes

posted May 6th, 2008 10:37 am


Andy has a point. A very undiplomatic one that is rather insulting to anyone in America, but still a valid point. The problem with the Atkins diet is that carbs are in a lot of things, including fruits, vegetables, Pulses, etc. The amount of carbs that you are allowed means your intake of all these good things is really limited. Our brains need a minimum of 130g of carbs a day to function correctly, and that?s JUST our brains, not our body. I?m not talking about processed junk like White bread, White Pasta, Cakes, Chips etc. I?m talking about Complex carbs like pulses, whole grains, vegetables etc. Everyone likes to argue that they are cutting out all this processed stuff and their Atkins diet is healthy, but we all have a certain amount of common sense, and does a diet that says ?you can have as much butter as you like, hell sit on your butt and eat it out of the tub with a spoon, but you have to watch those fruits and vegetables, they have too many carbs, they?ll kill you in the long run? seem like a good idea? I hate to say it people, but grandma was right when she sat you down and said you had to finish all your greens before you got up from the table, not that half a dead cow on your plate. And before anyone says I?m wrong and I haven?t ready the books or I?m stupid, I would just like to say?I?ve been studying and researching my PHD on this diet for the last 3 years, IT?S DANGEROUS!!! Please don?t do it. A thin body is no measure for a healthy one.

Andy, it sounds like you have A LOT of problems if you come onto a diet review website to bash dieters and Americans. You don't gain the weight back if you follow the Atkins diet properly. I'm happy for you that you are so perfect, physically. Obviously, there is much to be desired in other departments if you have nothing better to do!

posted Apr 28th, 2008 8:31 am


Uhmm, once you start eating carbs again you are going to gain the weight back extremely fast. And you all have energy? Its kind of sad to see all of you uneducated Amercians cutting vital nutrients and energy like carbohydrates out of your diet to lose some weight that you'll gain back unless you never consume carbohydrates again. And all you women who are on it.. noticed your periods slowing down, are you missing them? You need carbohydrates to maintain a normal menstrual cycle. You are also going to age prematurely.. and lose your sex drive.. This diet is actually increasing your risk of heart attack... and not excercising even? You all disgust me, how could you do this to your body? The american diet is a disgusting one. I excercise regularly, I eat properly, I'm at a perfect weight with a BMI of 19, I have perfect blood work, and best of all.. I EAT CARBOHYDRATES WITH EVERY SINGLE MEAL. Lazy fat Americans think they know everything..

I've been on atkins for over a month now and have so far lost near 15 pounds without exercising! the diet is amazing although i find it hard sometimes to eat things with no carbs. The trick to feeling good with this diet is not eating greasy fattening foods that are carb free. You may loose weight eating a pound of baccon a day but it wont make you feel any good. Lean proteins and lots of veggies is the only way to go!!

posted Apr 15th, 2008 11:52 am


Two things that most people miss. First, Atkins is not a diet per se as much as a lifestyle change. In essence, think of it as being allergic to carbs - you're limited for life. Second, the biggest problem with the diet is other people- "You CANT eat that - have some nice canned fruit!" etc. Traditional diets have been hammered into everyone's mind, so they think they're helping - ah, well. It had worked wonders for me, no lie! Good luck, all

I did the Atkins diet to go into the military, I needed to lose 11 pounds in 2 weeks. I thought it was impossible. I lost 16! I was so excited, I kept doing it until I lost 36 pounds in 3 months. I gain a little when I stop, but I just go right back on, and stick to the induction phase, I don't go forward in the phases. The cravings for bread potatoes, and all the other carbs stop after the first 2 weeks. So, stay strong! ..(by the way) you CAN have bread, pasta, and other carb foods, in moderation of course, in phase 3. I strongly recommend this diet. I have been using it on and off for 2 yrs, now, and my health is in great condition....add in diet green tea..(no carbs) to help with those health numbers you are concerned with....

posted Apr 2nd, 2008 6:48 pm


I have been on the Atkins Diet before..loved it. I lost over 50lbs in three months by sticking to the Induction Phase and adding a little more carbs. It was wonderful and I still eat that way now. Seriously people how can processed flour, sugary items and a bunch of starchy foods make you healthy. I stay away from red meat..have it about once a monthy and I stick mainly to chicken, fish and turkey. Every lunch I have a salad with roasted turkey breast slices and cheese, etc. I'm satisfied all afternoon. Love this way of eating.

Dr. Atkins did not die as a result of a heart attack but rather from a head injury in a fall on a slippery, icy sidewalk.

No matter how much I increased my cardio and no matter how much I decreased my caloric intake, I couldn't seem to lose any weight. I am on day 7 of the Atkins diet and have lost 7 pounds! It is amazing!

posted Mar 2nd, 2008 8:30 am


I had always struggled with weight and at my biggest was over 320 pounds. I read a lot about Atkins and his diet and did the diet for two years. I lost 150 pounds and I'm the best looking I've ever been and the healthiest. My blood pressure and Cholesterol are in good check and I feel great. For the critics out there, the diet does include lots of veggies... but fruits were not aloud... especially fruit juice and I missed that as well as bread and pasta because I'm Italian! Now I'm back to eating pasta occasionally but a balanced, small portion meal and exercise keeps me in check. The diet really is not intended for someone with a few pounds to lose. I think its bad for some people because ketosis can deplete calcium, fat, and muscle and its important to realize that if you've only got a handful of pounds to lose, that you can send your body the wrong message and gain it all back. Even if you're really over weight, you can gain it all back and more....just like any diet. Be smart, love yourself, do good things. Think of food as nutrition and not yummy, tasty stuff that feels good to check and swallow. Think about how much our world has way too much appeal and foods decorate our lives, if you will, and tempt us. Pretend you live on a farm and what you eat is what you can grow from the earth and the animals that we eat to sustain our lives Shop on the outside lanes of the grocery store... everything in the middle lanes are processed and sweet foods and food with chemicals and preserves. The outside lanes of the store have veggies, meats, cheese.... the stuff you'd have available to you if you lived on a farm. THE MIDDLE LANES ARE EVIL...LOL. Anyway, just thought I would share my process of shopping. Again.... love yourself. Don't stop trying and love yourself more and more. Feel great and know you are beautiful.

BACKGROUNDBACKGROUND Start the Diet Now Advertisement

More than 40 years ago, Dr. Robert Atkins introduced his low-carb diet, now popularly known as the Atkins Diet. The Atkins Diet is credited with starting the low-carb revolution. Although the buzz about low-carb diets has fizzled some, and mostly replaced by the increasingly popular Paleo Diet, the Atkins Diet is still around and there is a legion of people who still follow it.

The Atkins Diet has recently received a much needed update, releasing in early 2015 as Atkins 40. The updated Atkins program is a research-supported eating plan that still features the low-carb, high-protein principles of the original Atkins Diet, but with more leniency, simplicity, and variety. It seems very similar to The New Atkins for a New You launch a few years ago, but is targeted to promote sustainability and prevent participants from falling off the bandwagon due to excessive restriction.

Atkins 40 is marketed as more sustainable and more empowering, and ideal for those with 40 or fewer pounds to lose. The goal is to eat delicious and healthy food, like a variety of lean protein, leafy greens and other vegetables, nuts, fruits, and whole grains. In addition, tips and suggestions are perfect for those with busy lifestyles ensuring you that you can stick with Atkins at work, at home, on vacation, or when you're eating out.

Atkins 40 no longer includes the four basic Atkins phases: Induction, Ongoing Weight Loss, Pre-maintenance, and Lifetime Maintenance. Previously, many traditional Atkins participants wouldn’t go past Induction or Ongoing Weight Loss which caused them to fall off track due to excessive restriction. Atkins 40 targets more of a lifestyle shift creating a plan that someone could eat and follow for their whole life: no stages, no excessive restriction.

Do You Know the Best Diet Pills of 2023?

  • Encourages eating a proper combination of foods
  • Large weight loss the first couple of weeks
  • Program is thoroughly covered on the web site
  • More sustainable format than previous Atkins programs
  • Encourages eating more vegetables
  • Allows frequent eating to reduce hunger
  • You decide when to start your fitness program
  • Carb counting tools
  • Program updates focus as much on maintenance as weight loss
  • New plan offers more leniency than previous Atkins plan
  • Atkins Community web site available for free
  • Many find it extremely difficult to cut out breads and grains
  • Promotes excessive consumption of dairy, processed sweeteners, and packaged snacks
  • High caloric restriction, high need for tracking and counting
  • May overeat or include too much of the wrong type of protein
  • Can be high in cholesterol and saturated fat
  • Still may be too restrictive to create true lifestyle change
  • Difficult for vegetarians or vegans to follow their principles

Unlike previous Atkins programs, there are no longer four phases to follow. This means there is only one “plan” and lifestyle to build and maintain through Atkins 40. Principles remain the same with a focus on high-protein, low-carb food choices.

Through the Atkins Community online, you can customize your own meal plan, with Atkins 40 allowing you to use the 40-net grams of carbs however you like. Based on your choices, Atkins will share a one-week meal plan that includes breakfast, lunch, dinner and two snacks each day.

You don’t have to count any calories or carbs because all of that work is done for you. For exact measurements and recipes, simply click on the meal and you will be taken to the recipe for that meal.

You also have the chance to print out a grocery list for the week for your convenience. The total carb count for the day is shown at the bottom of each day’s meals. Below is an example meal plan:

  • Breakfast: Red Bell Pepper Rings Filled with Eggs and Mozzarella
  • Snack: Mushrooms Stuffed with Sausage and Mozzarella
  • Lunch: Spicy Meat Rolls
  • Snack: Atkins Day Break Creamy Chocolate Shake
  • Dinner: Grilled Salmon with Mixed Greens

Exercise is not a huge focus for the Atkins Diet. It is mentioned on the web site as a great way to maximize your chances of success. Exercise is a great complement for your nutrition plan and will help boost your energy. If you are not currently exercising, it is recommended that you wait a couple of weeks before starting an exercise regimen. Some of the exercises that are mentioned with the Atkins Diet include:

  • Brisk walking
  • Swimming
  • Water aerobics

Traditionally, Atkins was created for pre-diabetics or diabetics with over 40 pounds to lose, where it may have been impossible for them to start exercising right away. Atkins believes that diet and exercise go hand-in-hand, but that diet must come first and gentle exercise can be added later as a supplementary tool to build muscle and boost metabolism.


When you look at the Atkins Diet, there are some benefits as well as some drawbacks. It does help you lose weight quickly and it is important to notice that there are intense caloric restrictions involved, in addition to dramatic food choice changes. By reducing the amount of carbs you eat, you will be reducing blood sugar levels but you must also be careful that you don’t take in too much cholesterol or saturated fat, or an overabundance of processed snacks, dairy, sugar substitutes, and animal protein. Eliminating an entire food group such as carbohydrates may not work for everyone, but the diet does offer some benefits for those that can stick with it.

The online Atkins community may help to provide support when the guidelines seem too hard to maintain, and the addition of more on-the-go snack options may make it easier for those with a busy lifestyle looking to follow all Atkins principles. Hopefully the newer more lenient carbohydrate allowances will prevent excessive restriction and promote balance and sustainability for its followers.
