Where are we headed as a population ?
Obesity Worldwide
“ About 300 million people are estimated to be obese (with a Body Mass Index of 30 or more) with a further 700 million overweight. (a Body Mass Index of 25-29.9)”
“ More than 2.5 million deaths annually are weight-related. Deaths directly related to obesity have been estimated at 320,000 a year in Europe and more than 300,000 in the USA.”
The World Health Report 2004 estimated

Global Public Health Crisis: The Twin Epidemics
Obesity and diabetes are global problems affecting millions of people.
Over 1 billion people are overweight worldwide!
Overweight and obesity is increasing around the world including the USA, Europe, and Australia.
Obesity is a major risk factor for type 2 diabetes.

What Has Happened?
Major movement toward “Low Fat”
Often high in sugar/carbs
Lacking in satiety
Larger portions
Increase of convenience food
Usually high carb and high fat
Highly processed foods increase the amount of consumption of trans fats
Low in nutrients
Decrease in physical activity
Excess Carbohydrate Consumption: Effects Health, Weight and Energy Getting off the Blood Sugar Roller Coaster Here's what happens when you routinely consume lots of cards
Sample Carbohydrate Counts
Many “healthy” products derive at least
50% of calories from carbohydrates.

The Atkins Nutritional Approach™
Scientifically validated nutritional strategy for weight control and better health based upon controlling carbohydrate consumption.
This nutritional strategy stresses nutrient-dense carbohydrates as part of a balanced eating plan that includes a variety of protein and good fats, while restricting carbohydrates which have the greatest impact on blood sugar.
The ANA™ provides each person with the information that they need to find their individual level of carbohydrate intake, below which weight loss is achieved and above which weight gain occurs.
What is the ANA?
The Atkins Nutritional ApproachTM (ANA) is an easy-to-follow controlled carbohydrate program.
Initially, you cut back significantly on carbohydrates to lose weight; then you gradually add back into your diet a variety of nutrient-dense carbohydrates as you get closer to your goal weight.
The four phases is a tool to help you achieve your weight loss goals.
The ANA brings your nutritional intake into balance, helping you to re-energize, lose weight and lay the foundation for a healthy life.
The ATKINS LIFESTYLE FOOD GUIDE PYRAMID ™
How Does the ANA Work?
Carbohydrates and fat provide fuel for the body.
When carbohydrates are available, the body transforms them into energy first.
Any excess carbohydrates are stored as fat.
When carbs are sufficiently restricted, the body burns fat for fuel, including already stored own body fat, which allows people to lose weight or maintain their goal weight.
Studies show that certain risk factors for heart disease improve when individuals follow a controlled carbohydrate programme (e.g. triglyceride levels can decrease on average 44%).
What Controlling Carbs Means
Finding each individual’s tolerance level for Net Carbs (carbohydrates that impact blood sugar levels), first to lose weight and then maintain a healthy weight for life.
Cutting out processed foods full of sugar and white flour, as well as restricting other high-carb foods.
Eating a wide variety of delicious foods, including protein, “healthy” fats and nutrient-dense carbs.
It does NOT mean eating no carbs, eating only steak, bacon and eggs, or eliminating fruit and vegetables.
It DOES mean retaining “good” carbs full of nutrients, found in foods like dark green leafy vegetables, nuts and berries.
Atkins Carbohydrate Equilibrium (ACE)
The amount of carbohydrate an individual can eat each day while neither gaining nor losing weight.
What are Net Carbs?
Carbohydrates can have different metabolic effects on the body. Net Carbs are the carbohydrates that impact the blood-sugar level and are the only carbs that count when following Atkins.
Certain ingredients, such as glycerine and sugar alcohols, have a minimal impact on blood sugar, and therefore, are not included in a Net Carb count.
Note: In the US, fibre is reported as a carbohydrate. In the UK, fibre is reported separately and is not part of the carb count.
What Are the Carbs That Count?
Read nutrition labels:
Look for servings/package (there can be more than one serving/package
Total carbohydrates in grams/serving
Dietary fiber in grams/serving
Sugar alcohols in grams/serving
Net Carbs
Atkins products-see net carbs
Other products (to be safe)-subtract grams of dietary fiber and sugar alcohols from total carbohydrate grams, this is the number of carbs that count when doing Atkins.
ANI Historical Net Carb Definition
Total Carbs : 24 gms (Off Nutrition Fact Panel)
Minus:Fiber -14 gms (Pass Undigested)
Glycerine -4 gms (Digest Slowly, more like a fat)
Sugar Alcohols -2 gms (Digest Slowly without insulin spike)
NET CARBS 4 Gms
Breakthrough: “Net Atkins Count”
Evolving from “Net Carbs” to a better method…
Method based on actual measurement of Glycemic Impact vs. a calculated number.

The Atkins Nutritional Principles
Four principles:
Weight loss
Weight maintenance
Good health and well-being
Disease prevention
The Atkins Nutritional Principles
Weight Loss
Both carbohydrate and fat provide fuel for the body’s energy needs. Carbohydrate is the first fuel to be metabolized. However, when the intake of digestible carbohydrate is sufficiently restricted (without caloric restriction), the body converts from the primary metabolic pathway of burning carbohydrate to burning fat as its main energy source. This results in weight loss.
The Atkins Nutritional Principles
Weight Maintenance
For each individual there is a tightly regulated carbohydrate threshold below which fat burning and weight loss occurs. However, if the individual’s carbohydrate intake exceeds this threshold, carbohydrate burning predominates, allowing fat to be accumulated, resulting in weight gain. Therefore, each individual has a level of carbohydrate intake at which weight is maintained.
The Atkins Nutritional Principles
Good Health
By adhering to a controlled carbohydrate nutritional approach, an individual who chooses to eat nutrient-dense foods (including adequate fiber, healthy fats and supplementation as needed) is more likely to meet his nutritional needs and promote good health than he would by following a calorie-restricted, fat-deficient diet. Exercise is also essential for controlling weight, enhancing energy and maintaining a sense of well-being.
The Atkins Nutritional Principles
Disease Prevention
By following an individualized controlled carbohydrate nutritional approach that lowers carbohydrate intake resulting in lower insulin production, people at high risk for or diagnosed with certain chronic illnesses, including cardiovascular disease, diabetes and hypertension, can see improvement in clinical parameters.
The Atkins Nutritional Approach
The Atkins Nutritional Principles form the core of The Atkins Nutritional Approach
Four Phases:
Induction
Ongoing Weight Loss
Pre-Maintenance
Lifetime Maintenance
Phase 1: Induction
Limit carbohydrate consumption to 20 grams of Net Carbs per day for a minimum of 2 weeks.
For those with a significant amount of weight to lose, Induction can be followed for longer periods of time.
Satisfy appetite with foods that combine protein and fat, such as fish, poultry, eggs, lamb, pork and beef.
Consume a balance of healthy natural fats such as monounsaturated, polyunsaturated, and saturated.
Avoid trans fats (e.g. hydrogenated or partially hydrogenated oils)
Consume carbohydrates in the form of nutrient-dense foods such as leafy green vegetables.
Drink at least eight 250 ml glasses of water daily.
Exercise regularly.
Don’t forget to take nutritional supplements.
Example of Induction Menu
Breakfast
Three-Egg Omelette with Avocado
Mozzarella Cheese and Tomato
Decaffeinated Coffee with Cream
Lunch
Sirloin Steak ( 8 oz.)
Spinach and Mixed Lettuce Salad
with Mushrooms, Onions, Celery and Parmesan Cheese
Dinner
Poached Salmon ( 9 oz.)
Kale or Broccoli with Garlic, Lemon and Sesame Seeds
Phase 2: Ongoing Weight Loss
Slow down weight loss by gradually increasing daily Net Carb intake in weekly increments of 5 grams.
Go from 20 grams/day of Net Carbs one week to 25 grams/day the next week.
Increase carbs by 5 each week until weight loss stops.
Choose additional carbs wisely, adding back nutrient-dense foods:
More non-starchy veggies (e.g., asparagus, broccoli)
Eat at least three meals a day; skipping meals can impede weight loss.
You should not go more than 6 waking hours without a meal or snack.
Eat until you are satisfied, but not stuffed.
Drink plenty of water, at least eight 250ml glasses daily.
Look for hidden carbohydrates in prepared foods
Avoid excessive amounts of caffeine.
Look for reductions in clothing sizes; don’t rely entirely on the scales.
Don’t skip the supplements.
Top 10 Myths - and the FACTS
Myth No. 1: The ANA Is Unbalanced and Deficient in Basic Nutrition
FACT:
People frequently mistake the 20 gram Net Carbs per day Induction phase for the whole programme!
Even during the Induction phase, the ANA calls 12 net carbs of veggies or 5 daily servings of veggies such as salad (leafy greens like spinach and watercress), 1 cup (two ½-cup servings) of broccoli, and half an avocado.
After this phase, individuals raise their carb count gradually until they reach their ACE.
A person’s ACE could be up to 120 grams or more daily of nutrient-dense carbohydrates, including fruit, occasional potatoes, brown rice and whole grain bread!
Example of 20 Gram CHO Daily Menu
Breakfast
Three Egg Omelet with Avocado,
Mozzarella Cheese and Tomato
Decaffeinated Coffee with Cream
Lunch
Beef Round Steak (8 oz.)
Spinach and Mixed Lettuce Salad with Mushrooms, Onions, Celery and Parmesan Cheese
Dinner
Broiled Salmon (9 oz.)
Kale topped with Garlic, Lemon and Sesame Seeds

Myth No. 2: You Lose Mostly Water Weight on the ANA
FACT:
A portion of initial weight loss on any diet is water weight.
When one follows a controlled carbohydrate eating plan the body switches from burning carbohydrate to primarily burning stored fat for energy, resulting in the loss of stored fat.
This is evident through the loss of inches!
Research results have consistently demonstrated that weight lost after the first few days on a restricted carbohydrate programme is primarily fat and not water or lean body mass.
Myth No. 3: The ANA Is Only Effective Because Calories Are Restricted
FACT:
Calories are not restricted when doing Atkins
Individuals may end up eating fewer calories because they are generally less hungry and no longer obsessed with food.
Stable blood sugar throughout the day ensures fewer food cravings.
The food on this program is less processed and more nutritious than on the typical pre-Atkins menu.
Myth No. 4: The High-Protein Content of the ANA Causes Kidney Problems
FACT:
No one has as yet produced a study for review, or even cited a specific case in which the protein content of ANA causes any form of kidney disorder.
When someone is already diagnosed with kidney disease, they need to modify their total protein intake and consult closely with their doctor.
The Truth Behind Our Critics Claims
Claim: “High total protein intake…may accelerate renal function decline.” - Dean Ornish
The Facts: Scientific evidence is lacking for people with healthy kidneys.
“… protein restriction does not prevent decline in renal function with age, and, in fact is the major cause of that decline. A better way to prevent the decline would be to increase protein intake.” “There is no reason to restrict protein in healthy individuals in order to protect the kidney.” - Mackenzie Walser, Johns Hopkins University
Sources: Ornish, D., "Was Dr Atkins Right?," Journal of the American Dietetic Association, 104(4), 2004, pages 537-542. Walser, M.,”Effects of Protein Intake On Renal Function and On the Development of Renal Disease,” In: The Role of Protein and Amino Acids in Sustaining and Enhancing Performance , Institute of Medicine, Washington, DC: National Academies Press, 1999, pages 137-154.V
Myth No. 5: Fat Intake is Detrimental and Will Lead to Heart Disease
FACT:
A growing body of scientific literature demonstrates that a controlled carbohydrate eating plan, if followed correctly, reduces risk factors for heart disease and improves clinical health markers.
The body needs fats to survive and fats provide many health benefits.
Natural fats make individuals feel full sooner and keep dieters feeling less hungry for longer.
Low carb v low fat – followed correctly, studies show that a low carb eating plan can be more effective than a low fat plan in improving risk factors for heart disease
The Truth Behind Our Critics Claims
Claim: “A wide body of evidence links the consumption of animal protein…CVD, cancer, and other chronic clinical illnesses” - Dean Ornish
The Facts: Studies have shown inconsistent results.
A study from Harvard University showed that a high intake of protein (from animal and vegetables) lowered the risk of ischemic heart disease in women.
Replacing carbohydrates with protein may actually decrease the risk of ischemic heart disease.

Hu, F.B., Stampfer, M.J., Manson, J.E., et al., "Dietary Protein and Risk of Ischemic Heart Disease in Women," American Journal of Clinical Nutrition , 70(2), 1999, pages 221-227.
Myth No. 6: Ketosis Is Dangerous and Causes a Variety of Medical Problems
FACT:
The primary fuel in the body is glucose, generated from carbohydrate consumption.
When sufficient carbohydrates are not available the body turns to its secondary fuel source: fat.
Fat is burned as energy (lipolysis), producing byproducts called ketones. The process is called ketosis.
Ketosis should not be confused with the abnormal metabolic state, ketoacidosis.
Ketoacidosis is only a concern for diabetics whose blood sugar is out of control, or for alcoholics.
Myth No. 7: The ANA Causes Constipation Because It Lacks Fibre
FACT:
Doing Atkins means including fibre-rich foods such as spinach, aubergines, broccoli, asparagus and leafy greens. After the initial phase, it also includes soft fruits such as berries.
If the Induction phase is followed properly and all 5 servings of vegetables are included, the majority of individuals do not suffer from constipation. If more fibre is needed during the Induction phase, a fibre supplement is recommended.
Supplementing with fibre is unnecessary in the Ongoing Weight Loss (OWL) phase and beyond because fruits and more vegetables are introduced into the eating plan.
Drinking plenty (2 litres) of water each day is very important.
Myth No. 8: The ANA Increases the Risk of Osteoporosis
FACT:
During the first week of any weight loss programme, one loses water weight. When water is lost, so are calcium, potassium and magnesium. That’s why taking a multivitamin is so important. Calcium is not being leached from the bones.
Actual studies have shown urinary calcium loss lasted a few days. The body then re-adjusts itself to a regular state of homeostasis and the calcium loss in the urine stops.
In several studies published in peer review journals researchers followed adults and studied the short-term and long-term effects of a high-meat diet on calcium metabolism. The studies found no significant changes in calcium balance, nor was there any significant change in the intestinal absorption of calcium during the high-meat diet.
The Truth Behind Our Critics Claims
Claim: “High-protein diets may cause loss of calcium and decreased levels of urinary citrate leading to osteoporosis.” - Dean Ornish
The Facts: Scientific studies do not support this claim.
Hannan et al: Elderly people with lower protein intake had increased bone loss compared to those with higher intakes of protein.
Dawson-Hughes et al: Protein supplementation along with a reduction in carbohydrates did not increase urine calcium excretion and did increase circulation of IGF-I, a bone growth factor.
Sources: Ornish, D., "Was Dr Atkins Right?," Journal of the American Dietetic Association , 104(4), 2004, pages 537-542.

Myth No. 9: Lipolysis / Ketosis Causes Loss of Muscle Mass
FACT:
Typically, individuals on very low calorie diets can lose muscle mass because they have inadequate intake of protein.
Atkins is not calorie restricted and the high protein intake offsets any possible loss of lean body mass.
Myth No. 10: Atkins Will Cause Weakness,Fatigue,and a Lack of Energy
FACT:
During the first few days on Atkins, people may experience a mild fatigue as the body switches metabolic pathways.
After 3-4 days, the body has switched from a glucose metabolism to a fat metabolism.
Reducing caffeine and sugar intake can lead to short-term withdrawal symptoms, but they typically pass within the first week.
After the transition, individuals consistently report high energy levels.
The Science Behind Atkins Nutritional Principles
EMERGING RESEARCH
As recently as one decade ago, there was little interest in the medical community to research low carbohydrate diets
The Robert C. Atkins Foundation made the research possible
Now, the medical community cannot ignore the compelling results of these studies and have been seeking funding from The RCA Foundation and other organizations so they can do their own research
THE RESEARCH IS GROWING!
There are now 50 papers, reviews, abstracts, and conference presentations supporting Atkins
There 46 separate studies supporting Atkins (researchers of three research groups published multiple papers from their studies)
KEY POINTS
Most studies have found that people lose more weight on very-low-carbohydrate diets than on standard weight-loss diets.
Mechanisms of weight loss on these diets may go beyond water loss and include suppression of appetite, increasing the metabolic rate, decreasing metabolic efficiency, and shunting of nutrients away from fat storage.
Weight loss is usually associated with small to moderate reductions in lean tissue, very-low carbohydrate diets may have a protein-sparing effect compared with low-fat diets.
These diets may also have favorable effects on specific risk factors for cardiovascular disease (eg, fasting and postprandial triglyceride levels, high-density lipoprotein levels, and low-density lipoprotein particle size).
Research Supporting Atkins
The research has shown health benefits beyond weight loss in adults…
Research Supporting Atkins
Two studies showed improvements in obese children/adolescents .
Nine studies included adults with diabetes and showed beneficial effects.
All studies showed improvements in cardiovascular (heart) risk factors .
Benefits included improvements in triglycerides and HDL “good” cholesterol.

Trends & Opportunities
Carbohydrate awareness is a trend that is being driven by science and consumers
An increasingly knowledgeable public is reading food labels and taking note of sugar content, manufactured trans fats and excessive carbohydrates
We have an opportunity to play an important role by offering healthy options, free of high sugar content and manufactured trans fats, high in protein and fiber
The challenge is to develop products responsibly so they are healthy and effective, and to not just capitalize trends without regard for the impact on consumers’ health.
