Effectiveness of a weight loss diet

Obesity is linked with many chronic conditions; a reduction in the prevalence of obesity has increased global concerns. Dietary therapy plays an important part in weight control for obese patients, and several diets have been suggested, such as high-protein, low-carbohydrate diets. However, the effectiveness and health of this diet is inconclusive. Several trials have been performed to examine the health and effectiveness of this weight loss diet.

A 4-week randomized dietary manipulation trial in 13 males with obesity and hyperinsulinemia found a greater weight loss outcome in the high-protein diet relative to the high-carbohydrate diet group (Baba et al. 1999). The decline in the resting energy intake of the high-protein diet group is less significant, which means that the metabolic rate and lean body mass decreases relative to the other group (p<0.05). As insulin can be secreted from adipose tissues, rapidly reducing insulin levels to a normal range can be found in the high protein diet group. This study concluded that for people with hyperinsulinemia and obesity, a high-protein diet is conducive to weight loss. But the weakness of this study is the small sample size and short time.

Further research with larger sample size and longer duration was performed. 63 obese men and women were selected for a one-year randomized trial(Foster et al. 2003). The results found that although the weight loss was more obvious in the low-carbohydrate, high-protein, high-fat diet in the first 3 to 6 months compared to low-calorie, high-carbohydrate, low-fat traditional diet (p=0.01 and p=0.02). At one year, the differences in weight loss were not significant. The low-carbohydrate diet showed increased concentrations of healthy HDL cholesterol and decreased concentrations of triglyceride compared to the conventional group. Researchers also suggested that a longer-term evaluation of the safety of dietary effects should be carried out.

A 12-week prospective study of 31 obese patients revealed that low-carbon, the high-fat ketogenic diet is a safe and effective way to lose weight (Perez-Guisado et al . 2008), which significantly reduces weight, BMI, LDL concentration and increases HDL concentration. The most noticeable drop is in triacylglycerols (47.91%).

A meta-analysis of dietary questionnaire data from 15428 adults aged 45-64 yeats combined with ARIC from seven multinational prospective carbohydrate intake studies showed that too high or too low carbohydrate intake is associated with an increased risk of death (Seidelmann et al. 2018). Carbohydrate intake less than 30 percent has a hazard ratio of 1.58, carbohydrate intake greater than 65 percent has a hazard ratio of 1.15, indicating that 58 percent and 15 percent higher risk of death for low and high carbohydrate intake groups compared to 50-55 percent of reference carbohydrate intake, which is associated with the lowest mortality rate. Further experiments have shown that low-carbohydrate with plant-based protein is associated with a reduction in mortality, while animal-based protein is associated with an increase in mortality.

In conclusion, a low-carbohydrate, high-protein diet is effective for short-term weight loss (3-6 months), but the long-term effect is not obvious. The proportion of carbohydrate intake should be controlled within 50-55 percent, which is the safest ratio, and the plant-based protein may be more healthy in weight management compared to the animal-derived protein.
