Brief Summary

This study was planned to provide information about the effect of short-term high protein diet (HPD) feeding on endoplasmic reticulum stress. The definition of HPDs cannot be determined exactly. They are defined differently by various scientific authorities. However, the target is for protein to be approximately 30% of total energy in HPD. It has been determined that HPDs increase satiety, thermogenesis, and provide body weight loss and maintenance of loss. In general, there is evidence that HPDs provide more body weight loss in a short time compared to low protein diets. It has been emphasized that the effect of high protein diet on weight loss is related to creating satiety, thus reducing food intake and increasing thermogenesis. However, the physiological, biochemical and molecular events that occur due to HPD feeding are not fully understood and the results have not been explained. It has been determined that the effects of HPDs last between 1 and 6 days and 6 months. The absence of any study in the literature on the short-term and long-term effects of HPD on oxidative events in humans reveals the original value of this study. Therefore, considering that long-term HPD feeding may increase the risk of cardiovascular disease, blood pressure and blood lipid levels, the effect of short-term HPD feeding on endoplasmic reticulum stress will be investigated in order to avoid these side effects. Blood analyses planned for this prospective analytical study will be performed in GENKÖK Laboratory. Healthy individuals will be administered 10 days of HPD and a 10-day normal diet as a control.

Conditions

Effect of High Protein Diet on Endoplasmic Reticulum Stress

Keywords

Endoplasmic reticulum stress; High protein diet; Oxidative stress

Outcome Measures

Primary Outcomes (1)

• Endoplasmic reticulum stress after high protein diet

  After the diet, endoplasmic reticulum stress parameters (GRP78, PERK, Nrf2 and GPx-1) will be measured in the blood.

  Day after diet end

Study Arms (2)

High Protein Diet

EXPERIMENTAL

The energy composition of the high protein diet will be calculated as 40% carbohydrate, 30% protein and 30% fat. It will be stated that individuals should not eat anything other than the foods to be sent during the weeks of the diet.

Other: High Protein Diet

Normal Protein Diet

EXPERIMENTAL

The energy composition of the high protein diet will be calculated as 55% carbohydrate, 15% protein and 30% fat. It will be stated that individuals should not eat anything other than the foods to be sent during the weeks of the diet.

Other: Normal Protein Diet

Interventions

High Protein Diet OTHER

Individuals will be placed on a high protein diet for 10 days.

High Protein Diet

Normal Protein Diet OTHER

Individuals will be placed on a normal protein diet for 10 days.
