Statement of the Problem
This study focused on the comparison between non-calorie restricted diet, calorie restricted diet and calorie restricted low glycemic index diet to achieve healthy weight lost in apparently healthy humans.

METHODOLOGY | Back

This study utilized thirty (30) human participants grouped into non-calorie restricted (Diet I), calorie restricted (Diet II), and calorie restricted low glycemic index (Diet III) diets. The non-calorie restricted (Diet I) group did not follow a menu plan. The calorie-restricted diets (Diet II and III) were given during lunch following a menu plan with a total caloric intake of 1300 Kcal. Biomarkers for lipid and glucose profile were determined before and after the study for the three groups of participants.

RESULTS | Back

  1. Development of a calorie restricted weight loss diet and a calorie restricted low glycemic index (GI) diet of commonly consumed carbohydrate foods in the Philippines. In developing the· menus, patient preference, convenience, accessibility and cost were taken into consideration. Particular attention was given to moderating consumption of preferred foods, particularly amount and frequency processed food consumed at breakfast. The only difference between the two diets is the choice of the quality of carbohydrate.
    1. Low Calorie Diet - The calorie-restricted diet was composed of high glycemic index carbohydrate foods such as white rice, cereals, white bread, table sugar and fruits and vegetables from the Food Exchange List.
    2. Low Calorie, Low Glycemic Index Diet - The calorie restricted, low GI diet was composed of low glycemic index carbohydrate foods such as brown rice, whole grain cereals, root crops, coconut sap sugar and fruits and vegetables from the List of Low Glycemic Index of Commonly Consumed Carbohydrate Foods.
  2. Comparison Between the Calorie Restricted Diet and the Calorie Restricted Low Glycemic Index Diet in Terms of Weight Loss.
    1. Low Calorie Group - The mean weight of the calorie restricted group dropped from 62.0 to 60.1 kg. The group continued to lose weight during the 2"d and the 3rd month with a mean weight of 59.1 kg. The final weight at the end of the program was 58.3 with a total weight lost of 3.7 kg.
    2. Low Calorie, Low GI Group - The mean weights of the calorie restricted low GI group consistently declined throughout the program with a total weight loss of 4.5 kg. There was no statistical significance found between the total weight loss of the calorie restricted group and calorie restricted low glycemic index group. However there was a clinical significance between the two groups in terms of blood chemistry.
    3. Non-restricted Calorie Group - The non-restricted calorie group did not have a significant total weight loss throughout the program and significantly differed from the total weight loss of both calorie restricted and calorie restricted low glycemic index groups.

CONCLUSION: | Back

  1. Both the calorie restricted diet and the calorie restricted low GI diet are effective for weight loss. However, the calorie restricted low GI diet may be more effective in weight reduction and lowering triglyceride levels.
  2. The calorie restricted and the calorie restricted low GI diets are more effective than the non­calorie restricted diet in terms of weight reduction and triglyceride levels.

RECOMMENDATIONS | Back

  1. The calorie restricted low glycemic index diet may be recommended for weight management of overweight and obese humans in te1111s of weight loss and blood chemist1y
  2. The Calorie Restricted Low GI diet may be more effective when consumed for a longer period of time.
  3.  Information on Glycemic response of foods should be part of the nutrition counseling for weight management of the overweight and obese as well as in the proper control and management of type 2 diabetic patients.
  4. This study will create awareness for nutritionist, dieticians, doctors, educators and other health related workers to conduct further studies in the proper control and management of overweight and obesity as well as Type 2 Diabetes Mellitus.
  5. Further study on the calorie restricted low GI diet should be conducted in moderately raised serum glucose and lipid profile to obtain a more significant result.
