    • Summary
    • This journal compares different weight loss diet results based on the participant’s level of adherence to the particular diet. It was concluded by the researchers that weight loss relied more on how well someone adhered to the diet they were assigned rather than the type of diet itself. In the study, it was said that all three diets had an extremely low adherence rate, meaning that participants deviated from the diet plan very often. (This idea is an important take away since it demonstrates how difficult it is to follow the diet)

 

 

  1. An Analysis of Popular Weight Loss Diet Types in Relation to Metabolic Syndrome Therapeutic Guidelines
    • APA Reference
    • Summary
    • the Journal discusses how metabolic syndrome contributes to cardiovascular disease or death but how the different diet plans may be a valid treatment option. Within the journal, the method to follow the zone diet is included. The diet involves a proportion of 40% carbohydrates, 30% fat, and 30% protein. As long as the proportions match, the amount of food is not limited in the diet. The effectiveness of the zone diet was tested in a trial and was determined that the diet did in fact help reduce the risk of cardiovascular disease including weight loss. Of course at the end of the article, it is said that there is not enough data to recommend these diets, one of the main reasons is the level of commitment needed. (The source is used to relate to the first because of the adherence to a diet) zone diet is not a low-carb diet, its level of difficulty may be attributed to the food proportion measurements.

    • Summary
    • In this study, different diets are analyzed for their effectiveness for weight loss and disease prevention. Some of the important data gathered from all these diets is that none of them caused any negative changes for the participants. For the zone diet participants, weight was lost as well as positive changes to HDL, LDL, and triglycerides. This indicates that a positive result is likely when changes to the original diet are adjusted. (It may not be possible to adhere completely to the exact diet regimen, but small changes in an original diet may yield positive health benefits)

 

  1. Maintenance on a ketogenic diet: voluntary exercise, adiposity and neuroendocrine effects

    • Summary
    • This study serves to determine whether a low carbohydrate diet effects the activity level. This is important because if someone were to follow a diet and lose weight in the short-term, weight loss in the future would be much more difficult if the activity level is decreased. The experiment involved two groups of rats that were given the low carbohydrate food versus the normal stuff. The data gathered showed that the rats that ate the low carbohydrate diet were fatter than the rats that ate the normal food when both groups had a lack of physical activity. However, in the groups that both exercised in the running wheel, both rat groups had the same level of fat tissue. (For humans, this is significant because the data shows the fallacy of diets that just promise short-term weight gain. A particular diet change alone may not yield desirable results if not combined with exercise) the effects of how a diet change would affect someone is likely how it changes the amount or type of food intake. 

 

  1. Weight loss and metabolic benefits with diets of varying fat and carbohydrate content: separating the wheat from the chaff

    • Summary
    • this journal serves to test differences between diets containing different macromolecule variations such as low carbohydrate diets and low fat diets. In the results, it was found that low carbohydrate diets were more effective than low fat diets for short-term weight loss. Some results that in the longer term, both diets seem to provide the same amount of weight loss. The  low carbohydrate diets were more beneficial in improving triglycerides, HDL, and A1c’s. But the low-fat diets lead to an improvement in total cholesterol and LDL levels. The importance of this research shows the potential effectiveness of certain diet changes. Additional information given states that the research is not conducted long enough to guarantee results. But the information does show the potential benefits in the long term.
