Summary

This study was planned to observe the acute effects of minimally processed and ultra-processed food (UPF) consumption on appetite in participants with normal body mass index (BMI) \[BMI: 18.5-24.99 kg/m2\] and overweight-obese (BMI \> 25 kg/m2) according to the NOVA (not an abbreviation) classification and to compare the postprandial effects of minimally processed and UPF consumption on appetite in normal and overweight-obese individuals. The study was designed as a non-randomized controlled, crossover study. The main questions it aims to answer are:

* Does a breakfast consisting of UPF affect appetite regulation differently compared to a breakfast consisting of unprocessed or minimally processed foods?
* Do the effects of foods with different levels of processing on appetite regulation vary by BMI?

Researchers will evaluate the effects of a breakfast containing unprocessed or minimally processed foods and a breakfast containing ultra-processed foods, which are similar in terms of energy and macronutrients, on appetite regulation.

Participants will:

* 1st experiment day: come to the laboratory where the experiment will be conducted at 8:00 am on an empty stomach and consume a breakfast containing unprocessed or minimally processed foods (chicken egg (boiled), white cheese (full-fat), black and green olive, tomato, cucumber, white bread, orange juice (freshly squeezed).
* 2nd experiment (after 2 weeks wash-out from 1st experiment): come to the laboratory where the experiment will be conducted at 8:00 am on an empty stomach and consume a breakfast containing ultra-processed food (packaged sandwich bread, beef sausage (pan-fried without oil), tomato ketchup, packaged orange juice).

Conditions

  • Healthy Adult Volunteers

Interventions

OTHER

Traditional Breakfast

In this intervention, participants are offered a traditional breakfast (consisting of unprocessed or minimally processed foods), and postprandial appetite regulation is evaluated. Traditional breakfast includes chicken egg (boiled), white cheese (full-fat), white bread, black and green olives, tomatoes, cucumbers, and freshly squeezed orange juice.

OTHER

UPF Breakfast

In this intervention, participants are offered an ultra-processed breakfast, and postprandial appetite regulation is evaluated. Ultra-processed breakfast includes pan-fried beef sausage (without oil), packaged sandwich bread, tomato-based ketchup, and packaged orange juice.
