Weight loss is often attributed to cancer but no clear answer to this question exists. It has long been believed that this could be due to malnutrition or obesity but there has been no conclusive information about either. A major limitation of medical research into this subject has been the tendency of using animal models of such diseases to investigate the impact of diet in humans. These studies indicate that a reduction in the calories consumed in comparison to normal calorie levels should lead to a significant change in the body weight. However, although many studies have been published, the results are often not conclusive as many variables could be influencing the outcome of a study and a difference in body weight between those individuals that have been given a specific diet versus those that have not cannot be observed in animal models. In addition, there are many factors that could not be controlled in the animal models and so researchers have found it difficult to draw firm conclusions. This review is aimed at providing further information on the effects of diets as a means of reducing the risk for weight gain. This will take into account the effects of a reduction in the calorie intake in comparison to normal calorie levels. This article explores the different types of diets considered by researchers and the role of the various hormones in their effects. The review concludes that each type of diet seems to have different potentials to increase or to decrease the risk for weight gain. However, at present there is no specific research that supports a single and consistent diet for weight management. It will be discussed which types of diets are most likely to be effective in the prevention and promotion of weight loss. This approach to treatment will therefore be followed in future articles on diet and weight management based on the findings of this review.
This is the second part of the four-part series describing the architecture and design process with PostgreSQL.
Part 1: Introduction
Part 2: Design Goals
Part 3: Design Tools
Part 4: Design Quality Requirements
The first article dealt primarily with design goals before the designs were created. The second article focuses on the design process of defining architecture and design tooling. The third article focuses on what tools are required for a successful PostgreSQL architecture. And the final article discusses the quality requirements for a strong architecture.
For this series, I decided to discuss design quality, as a goal for design processes. I also decided to write the articles in a way that is compatible with the standard conventions of the Open Source community of PostgreSQL. I started with the postgresql-design-quality. This article has been prepared and
