The raison d'etre of this website is to provide you with hard scientific information which may help you make informed decisions in your quest for health (so far I have blogged concise summaries of over 1,500 scientific studies and have had three books published).

My research is mainly focused on the effects of cholesterol, saturated fat and statin drugs on health. If you know anyone who is worried about their cholesterol levels and heart disease, or has been told to take statin drugs you could send them a link to this website, and to my statin or cholesterol or heart disease books.

Very low-carbohydrate diets can help to lose a significant amount of fat

This post includes a synopsis of a paper published in the Journal of the International Society of Sports Nutrition 2004; 1(2): 7–11 and instructions on how to make beef tallow.

New Atkins for a New You: The Ultimate Diet for Shedding Weight and Feeling Great.
Books:
In this review Manninen investigated the effects of a very low carbohydrate intake. He explains that ketones are produced with a very low carbohydrate intake which causes a harmless physiological state known as dietary ketosis. These ketones flow from the liver to other tissues (e.g., brain) for use as a fuel.

Manninen found:
(a) In comparison with glucose, ketones are actually a very good fuel, and there is no clear requirement for dietary carbohydrates for human adults.
(b) Ketones may offer therapeutic potential in a variety of different common and rare diseases.
(c) Very low-carbohydrate diets cause a significant reduction in fat mass and a concomitant increase in lean body mass.

To conclude: Very low carbohydrate diets produce ketones. Ketones are a very good fuel for the brain, may be useful in treating various diseases and can help to lose a significant amount of fat.

Researchers question the validity of present-day (low-fat, high carbohydrate) dietary guidelines

This post contains a summary of a paper published in Current Opinion in Clinical Nutrition and Metabolic Care 2004 Jul;7(4):485-92 and a recipe for green chicken masala.

New Atkins for a New You: The Ultimate Diet for Shedding Weight and Feeling Great.
Books:
Acheson notes that the Atkins diet has been criticized and vilified by much of the scientific community since it was proposed 30 years ago, because it challenged nutritional recommendations and dietary guidelines for a healthy diet. However, in spite of such recommendations the prevalence of obesity continues to rise. The present review evaluates recent scientific evidence and attempts to reach consensus on the confusion of weight-reducing diets.

The review found that low-carbohydrate, Atkins-type diets have been demonstrated to have positive effects on weight loss and biomarkers of cardiovascular risk, which has prompted some researchers to question the validity of present-day (low-fat, high carbohydrate) dietary guidelines.

Protein Power: The High-Protein/Low-Carbohydrate Way to Lose Weight, Feel Fit, and Boost Your Health--in Just Weeks!
Books:
This review examined and compared the safety and the effectiveness of a low carbohydrate diet as an alternative to a low-fat, high-carbohydrate diet, which is the current standard for weight loss and/or chronic disease prevention.

The review found:
(a) In short-term and long-term comparison studies, low carbohydrate diets performed as well as or better than comparable low fat diets with regard to weight loss, cholesterol levels, glucose and insulin response, blood pressure, and other important cardiovascular risk markers in both normal subjects and those with metabolic and other health-related disorders.
(b) The metabolic, hormonal, and appetite signaling effects of carbohydrate reduction suggest an underlying scientific basis for considering it as an alternative approach to the low fat, high-carbohydrate recommendations in addressing overweight/obesity and chronic disease.

Hite concludes: It is time to embrace low carbohydrate diets diets as a viable option to aid in reversing diabetes mellitus, risk factors for heart disease, and the epidemic of obesity.

Trick And Treat - how 'healthy eating' is making us ill
Books:
In this study 23 older adults with mild cognitive impairment were assigned to either a (i) high carbohydrate or (ii) very low carbohydrate diet for 6 weeks.

The study found after 6 weeks:
(a) Improved verbal memory performance for the low carbohydrate subjects.
(b) Reductions in weight in the low carbohydrate subjects.
(c) Change in calorie intake, insulin level, and weight were not correlated with memory performance for both groups.
(d) Higher ketone levels were positively correlated with better memory performance.

To conclude: In older adults with increased risk for Alzheimer's disease, these findings indicate that very low carbohydrate consumption, even in the short term, can improve their memory function.

This study can be accessed at: http://www.ncbi.nlm.nih.gov/pubmed/17971178

This study of 13 diabetic and 13 non diabetic subjects evaluated whether a low carbohydrate diet could allow diabetic and non diabetic subjects to lose weight.

Subjects followed either a higher fat/low carbohydrate diet or a "healthy eating" (higher carbohydrate/lower fat) diet following Diabetes UK nutritional recommendations.

After 3 months both diabetics and non diabetics on the low carbohydrate diet lost over 3 times as much weight as those on the "healthy-eating" (high carbohydrate) diet.

Obesity is linked to diabetes so the weight reducing higher fat/low carbohydrate diet is more effective at treating diabetes than the Diabetes UK "healthy eating" diet.

Recipe of the day

Tomato, Chili Pepper, and Sweet Onion Frittata

Ingredient list:
1 10-ounce can of diced tomatoes and chilies
3 Dozen Fresh Farm Eggs
Food Mall: Eggs
Three fresh eggs
Sweet yellow onion
Garlic powder
Black pepper
Dried cilantro
Salt
Extra virgin olive oil

Directions:
Pre-heat oven to 350 degrees. Chop enough onion to cover the bottom of a small frying pan. Open can and transfer tomatoes and chilies to an air-tight container to refrigerate leftovers. Crack three eggs into a small mixing bowl. Add salt, black pepper, garlic powder, and dried cilantro to taste. I’ve been on a cilantro-kick lately and have been adding it heavily. Stir with a fork or whisk to mix well.

Heat one tablespoon of oil in the bottom of a small frying pan over medium heat on the stove top. Add onion and let cook in the hot oil. Add tomatoes and chilies to the frying pan using a fork or slotted spoon to reduce the transfer of liquid. I need 2 fork full’s to cover the surface of the skillet. Let the mixture cook a bit, and then pour eggs over the vegetables and let cook until the edges begin to brown and can be edged away from the sides of the pan with a spatula (one or two minutes). Move the frying pan to the oven and let bake about six minutes until the eggs set fully and the top becomes firm to the touch. When done, remove from the oven and transfer to a plate.
