Eating More Dairy to Lose Fat

Cheese, Cream, more cheese, in fact everything and anything dairy can be found on many lowcarb plates.

We would be lost without it.

But, as this article shows, eating dairy is more than just a way to cut down on carbs…

Eating high calcium, higher fat dairy foods, have been a long term stable tenant of the low-carb way of eating, and for good reason – it works – as part of a healthy low carb regime.

Now, a recent study conducted in Denmark has observed that the more calcium you eat in your diet the less body fat you will have, and therefore the less you will weigh.  This points to the fact that not only is dairy a high-energy food, it could be that dairy itself can help you absorb less fat.

Professor Arne Astrup, Head of Human Nutrition at the Royal Veterinary and Agricultural University in Copenhagen, Denmark, undertook a study to prove this fact.

In the study, a group of volunteers spent one week eating a diet that was high in calcium, typically more than 2000milligrams of calcium a day; and week 2 was on a low calcium diet, where they were eating around about 500milligrams of calcium a day.

These diets were designed so that they had the identical amount of calories and crucially, they also had the same fat content each week.

The known science led the researchers to expect that the higher calcium diet would indeed cause the body to absorb less fat than on the lower calcium diet.

However, the results that actually came out were even better than expected, in fact on the higher calcium diet tests on the subjects excretions showed that they passed through twice as much fat as they did on the lower calcium diet.

Putting that another way, on the higher calcium diet they absorbed only half the amount of fat than they did on the lower calcium diet.

What this means for low-carbers is that when you eat dairy products, not all of their calories count.

But of course, that still doesn’t give you an excuse to binge out on cheese!

Protein is More Satisfying.

Low carbers have known the simple truth for many years that a meal rich in protein will help you last between meals without getting an attack of the munchies.

Why have the scientists taken so long to catch up?

I’ve long maintained that higher protein foods are always going to be the most filling. Mainly because they take longer for the body to digest, therefore remain in the stomach and intestines that little bit longer, meaning our bodies aren’t signalling us saying “hey, we’re hungry – give us more food!”

And to a certain extent – now- science is starting to back that up.

I’ve long maintained that higher protein foods are always going to be the most filling. Mainly because they take longer for the body to digest, therefore remain in the stomach and intestines that little bit longer, meaning our bodies aren’t signalling us saying “hey, we’re hungry – give us more food!”

And to a certain extent, science does back that up.

If you look over the research papers that have been carried out, certainly over the last ten years, they clearly show that 8 out of 10 people ate less after a protein-rich meal than they did after a meal that was low in protein.

Some time ago, the BBC  carried out a test to prove whether this was so or not. What they did was to take 3 volunteers who worked long hours, and were used to snacking on the job.

What they wanted to do was to see if they could give them a meal that would set them up for the long day ahead, so that they wouldn’t need to snack whilst working on their shifts. They fed each of the volunteers a meal that had the same calorific value but whose contents varied in the proportion of fat, protein and carbohydrates – one being high in fat, one high in protein and one high in carbohydrates.

After the meal, they were kept under close observation, to make sure that they couldn’t sneak any crafty snacks. After a four hour period, they were each given pizza slices to eat, and carefully observed as they tucked into the richly-deserved reward.

The one who ate the most was the one who had the initial meal that was high in carbohydrates. The quantity he ate was closely matched by the one whose diet was high in fat. The person who ate the smallest amount during the lunch-break was the one who had had the protein rich meal.

It was a very simple test, but it did rather prove the fact that if you don’t want to get hunger pains between meals, then make sure your meals are high in protein.

It’s as simple as that.

Benefit of Higher Protein Diet and Execise

Everyone knows that a good weight-loss program combines diet and exercise, However, a University of Illinois study reports that exercise is much more effective when it’s coupled with a protein-rich diet.

There’s an additive, interactive effect when a protein-rich diet is combined with exercise. The two work together to correct body composition; dieters lose more weight, and they lose fat, not muscle,” said Donald Layman, a U of I professor of food science and human nutrition.

A higher-carbohydrate, lower-protein diet based on the USDA food guide pyramid actually reduced the effectiveness of exercise, Layman sai

Forty-eight adult women participated in Layman’s 4-month study, published in the August 2005 issue of the Journal of Nutrition. One group ate a protein-rich diet designed to contain specific levels of leucine, one of the essential amino acids. A second group consumed a diet based on the food guide pyramid, which contained higher amounts of carbohydrates.

Both groups consumed the same number of calories, but the first group substituted high-quality protein foods, such as meats, dairy, eggs, and nuts, for foods high in carbohydrates, such as breads, rice, cereal, pasta, and potatoes.

“Both diets work because, when you restrict calories, you lose weight. But the people on the higher-protein diet lost more weight. Some people refer to this as the metabolic advantage of a protein-rich diet,” said Layman.

The study included two levels of exercise. “For one group, we recommended that they add walking to their lives. They usually walked two to three times a week, less than 100 minutes of added exercise,” the researcher said.

The other group was required to engage in five 30-minute walking sessions and two 30-minute weightlifting sessions per week. In both groups of dieters, the required exercise program helped spare lean muscle tissue and target fat loss. But, in the protein-rich, high-exercise group, Layman noted a statistically significant effect. That group lost even more weight, and almost 100 percent of the weight loss was fat, Layman said. In the high-carbohydrate, high-exercise group, as much as 25 to 30 percent of the weight lost was muscle.

While this protein-rich diet works for everyone, it seems to be even more effective for people who have high triglyceride levels and carry excess weight in their midsection–a combination of health problems known as Syndrome X.

“The protein-rich diet dramatically lowered triglycerides and had a statistically significant effect on trunk fat, both risk factors associated with heart disease,” he said. “Exercise helped dieters lose an even greater percentage of body fat from the abdominal area.”

The protein-rich diet works so well because it contains a high level of the amino acid leucine. Leucine, working together with insulin, helps stimulate protein synthesis in muscle. “The diet works because the extra protein reduces muscle loss while the low-carbohydrate component gives you low insulin, allowing you to burn fat,” he said.

“We believe a diet based on the food guide pyramid actually does not provide enough leucine for adults to maintain healthy muscles. The average American diet contains 4 or 5 grams of leucine, but to get the metabolic effects we’re seeing, you need 9 or 10 grams,” he noted.

To achieve that leucine level, the researcher recommended adding dairy, meat, and eggs, all high-quality proteins, to the diet. According to Layman, losing weight doesn’t have to mean relying on supplements to fill in nutritional gaps in your diet. “If you use a high-quality protein approach to your diet, you can actually improve the overall quality of your diet while losing weight,” he said.

My comment on that…

Layman’s diet for the study was lower in fat and called for more fruits and vegetables than say the Atkins diet but other diets such as Barry Sears Zone Diet and the South Beach Diet are much closer to the target regime the dieters in the study followed.

What is telling though is the fact that none of the USDA food pyramid have been shown scientifically not to be adequate and that by following the USDA recommended dietary proportions you are actually decreasing the effectiveness of the diet and exercise.

How is that for vindication of the low carb diet?

While the study was carried out using female participants, there are excellent indications that similar results would be obtained for men. Particularly when you realise that most men carry their excess weight around the mid section in the infamous beer belly.

Note too, that the high carb group lost muscle mass while in the high protein group the losses were almost entirely FAT.

Other researchers involved in the study are Ellen Evans, Jamie I. Baum, Jennifer Seyler, Donna J. Erickson, and Richard A. Boileau, all of the University of Illinois. The study was funded by the Illinois Council on Food and Agricultural Research (C-FAR), the National Cattlemen’s Beef Association, the Beef Board, and Kraft Foods.
