Paleo Diet Ranked Worst Diet | The Compost Bin | Forums

What a bunch of crap, I love their reasoning for it not being a good diet

Experts took issue with the diet on every measure. Regardless of the goal—weight loss, heart health, or finding a diet that’s easy to follow—most experts concluded that it would be better for dieters to look elsewhere. “A true Paleo diet might be a great option: very lean, pure meats, lots of wild plants,” said one expert—quickly adding, however, that duplicating such a regimen in modern times would be difficult.

So the reason the diet sucks is because the food industry has gotten so far away from what food really is, that it's hard for people to follow?

But hey slimfast is number 13 on the list

5 Studies on The Paleo Diet – Does it Actually Work?

January 23, 2014 | by Kris Gunnars | 2,226 views | 2 Comments

To date, 5 human intervention studies have been done on the paleo diet.

In this article, I take a look at each of these studies and their conclusions, then I summarize the findings at the end.

Woman Wondering Whether to Eat Meat or Vegetables

The paleo diet emulates the diet of our hunter-gatherer ancestors, based on the premise that they did not suffer from the same diseases as modern humans.

This diet advocates consumption of unprocessed animals and plants, including meat, fish, eggs, vegetables, fruits, nuts and seeds.

It shuns processed foods, sugar, dairy and grains, although some of the more modern “versions” of paleo do allow foods like dairy and rice.

The Studies

All of these studies are done in humans and are published in respected, peer-reviewed scientific journals.

1. Lindeberg S, et al. A Palaeolithic diet improves glucose tolerance more than a Mediterranean-like diet in individuals with ischaemic heart disease. Diabetologia, 2007.

Details: 29 men with heart disease and elevated blood sugars or type 2 diabetes, were randomized to either a paleolithic diet (n=14) or a Mediterranean-like diet (n=15). Neither group was calorie restricted.

The main outcomes measured were glucose tolerance, insulin levels, weight and waist circumference. This study went on for 12 weeks.

Glucose Tolerance: The glucose tolerance test measures how quickly glucose is cleared from the blood. It is a marker for insulin resistance and diabetes.

This graph shows the difference between groups. The solid dots are the baseline, the open dots are after 12 weeks on the diet. Paleo group is on the left, control group on the right.

Lindeberg, et al. 2007.

As you can clearly see from the graphs, only the paleo diet group saw a significant improvement in glucose tolerance.

Weight Loss: Both groups lost a significant amount of weight, 5 kg (11 lbs) in the paleo group and 3.8 kg (8.4 lbs) in the control group. However, the difference was not statistically significant between groups.

The paleo diet group had a 5.6 cm (2.2 inches) reduction in waist circumference, compared to 2.9 cm (1.1 inches) in the control group. The difference was statistically significant.

A few important points:

The 2-hour Area Under the Curve (AUC) for blood glucose went down by 36% in the paleo group, compared to 7% in the control group.

Every patient in the paleo group ended up having normal blood sugars, compared to 7 of 15 patients in the control group.

The paleo group ended up eating 451 fewer calories per day (1344 compared to 1795) without intentionally restricting calories or portions.

Conclusion: A paleolithic diet lead to greater improvements in waist circumference and glycemic control, compared to a Mediterranean-like diet.

2. Osterdahl M, et al. Effects of a short-term intervention with a paleolithic diet in healthy volunteers. European Journal of Clinical Nutrition, 2008.

Details: 14 healthy medical students (5 male, 9 female) were instructed to eat a paleolithic diet for 3 weeks. There was no control group.

Weight Loss: Weight decreased by 2.3 kg (5 lbs), body mass index decreased by 0.8 and waist circumference went down by 1.5 cm (0.6 inches).

Other Markers: Systolic blood pressure went down by 3 mmHg.

Conclusion: The individuals lost weight and had a mild reduction in waist circumference and systolic blood pressure.

3. Jonsson T, et al. Beneficial effects of a Paleolithic diet on cardiovascular risk factors in type 2 diabetes: a randomized cross-over pilot study. Cardiovascular Diabetology, 2009.

Details: 13 individuals with type 2 diabetes were placed on either a paleolithic diet or a typical Diabetes diet in a cross-over study. They were on each diet for 3 months at a time.

Weight Loss: On the paleo diet, the participants lost 3 kg (6.6 lbs) more weight and lost 4 cm (1.6 inches) more off of their waistlines, compared to the Diabetes diet.

Other Markers:

HbA1c (a marker for 3-month blood sugar levels) decreased by 0,4% more on the paleo diet.

HDL increased by 3 mg/dL (0.08 mmol/L) on the paleo diet compared to the Diabetes diet.

Triglycerides went down by 35 mg/dL (0.4 mmol/L) on the paleo diet compared to the Diabetes diet.

Conclusion: The paleo diet caused more weight loss and several improvements in cardiovascular risk factors, compared to a Diabetes diet.

4. Frassetto, et al. Metabolic and physiologic improvements from consuming a paleolithic, hunter-gatherer type diet. European Journal of Clinical Nutrition, 2009.

Details: 9 healthy individuals consumed a paleolithic diet for 10 days. Calories were controlled to ensure that they wouldn’t lose weight. There was no control group.

Health Effects:

Total Cholesterol went down by 16%.

LDL Cholesterol went down by 22%.

Triglycerides went down by 35%.

Insulin AUC went down by 39%.

Diastolic Blood Pressure went down by 3.4 mmHg.

5. Ryberg, et al. A Palaeolithic-type diet causes strong tissue-specific effects on ectopic fat deposition in obese postmenopausal women. Journal of Internal Medicine, 2013.

Details: 10 healthy women with a BMI over 27 consumed a modified paleolithic diet for 5 weeks. There was no control group.

Main outcomes measured were liver fat, muscle cell fat and insulin sensitivity.

Weight Loss: The women lost an average of 4.5 kg (9.9 lbs) and had an 8 cm (3.1 inches) reduction in waist circumference.

Liver and Muscle Fat: The fat content of liver and muscle cells are a risk factor for metabolic disease. In this study, the women had an average reduction in liver fat of 49%, but no significant effect on the fat content of muscle cells.

This graph shows how the fat content in liver cells decreased:

Ryberg, et al. 2013

As you can see, the women who had a lot of liver fat (fatty liver) had the most significant decrease.

Other Health Effects:

Blood pressure went down from an average of 125/82 mmHg to 115/75 mmHg, although it was only statistically significant for diastolic blood pressure (the lower number).

Fasting blood sugars decreased by 6.35 mg/dL (0.35 mmol/L) and fasting insulin levels decreased by 19%.

Total cholesterol decreased by 33 mg/dL (0.85 mmol/L).

Triglycerides went down by 35 mg/dL (0.39 mmol/L).

LDL cholesterol went down by 25 mg/dL (0.65 mmol/L).

HDL cholesterol decreased by 7 mg/dL (0.18 mmol/L).

ApoB decreased by 129 mg/L (14.3%).

Conclusion: During the 5 week trial, the women lost weight and had major reductions in liver fat. They also had improvements in several important health markers.

Studies That Were Not Included

I skipped the following two studies because they weren’t applicable:

Jonsson T, et al. 2006 – This is a randomized controlled trial, but it is done in pigs, not humans.

O’Dea K. 1984 – In this study, 10 diabetics lived as hunter-gatherers for 7 weeks and had incredible improvements in health. Very interesting study, but there are too many confounders to conclude anything about the diet itself.

So, only human studies that isolate diet as the sole variable are included in the analysis.
