Intermittent Fasting vs. High-intensity Interval Training on the Lipid Profile of Obese Individuals.

Group A participants followed the IF diet for 6 weeks . intermittent fasting , specifically time-restricted feeding (TRF), involves consuming all of one's energy requirements inside an 8-h.The fasting interval was designated as 16 h, and the other 8-h was the eating period . During the 8-h eating window, the patient consumes a well-balanced meal consisting of 55%-65% carbs, 7%-20% protein, and 15%-30% fat .

. Group B engaged in low-volume HIIT exercise (aerobic activity) three times weekly for six weeks. The exercise routine consisted of a 5-min warm-up phase at 70% of MHR, followed by four intervals of 2-min maximum effort cycling sessions (4 × 2 HIIT) compared to a sub-maximal workload at 85%-90% of MHR. The participants engaged in four work bouts, with each bout lasting around 4 min and followed by a 4-min rest period. During the workouts, the participants maintained an HR of 60%-70% of their MHR. This resulted in 8 min of intense physical activity during each training session. Additionally, there was a 5-min cooling down phase at 70% of the MHR. The treatment's intensity was adapted based on the modified Bruce protocol.
