| Abstract | Objective: Previous studies have established the effectiveness of low-carbohydrate or ketogenic diets in promoting for weight loss, while exercise in hypoxia has shown potential for improving cardio-metabolic health outcomes. However, it remains unclear whether the combined use of these two strategies results in additional health benefits. Thus, the purpose of this study was to evaluate the advantages of a short-term ketogenic diet combined with moderate-intensity continuous training (MICT) under normobaric normoxia or hypoxia (simulated at an altitude ranging from 2500 to 4500 m) among overweight young individuals. Methods: A total of 89 overweight young adults (44 m and 45 f) completed a 4-week intervention. The participants were assigned into four groups: a group following a normal diet without exercise training in normoxia (CON, n = 24), a group following a ketogenic diet without exercise training in normoxia (KD, n = 24), a group performing MICT with a ketogenic diet in normoxia with an inspired fraction of oxygen (FIO2) of 0.209 (KD-NMICT, n = 21), and a group doing MICT with a ketogenic diet in hypoxia with an FIO2 range of 0.15-0.11 referred to as KD-HMICT (n = 20). The MICT protocol consisted of 30 min of continuous cycling training at 50%-60% of maximal oxygen peak (VO2peak). Anthropometric and cardiorespiratory fitness measurements were assessed at baseline and after the 4-week intervention. Results: After intervention, all three KD groups experienced significant reductions in body weight (−5.2 kg in KD, −4.7 kg in KD-NMICT, and −7.5 kg in KD-HMICT, p < 0.01) and BMI (−6.7% in KD, −6.1% in KD-NMICT, and −9.3% in KD-HMICT, p < 0.01). The reduction in VO2peak was similar between the KD group (-8.3%) and the CON group (-6.9%). However, the KD groups incorporating MICT showed improvements in VO2peak, with a 1.2% increase in KD-NMICT (p < 0.05, d = 0.7) and a 10.9% increase in KD-HMICT (p < 0.05, d = 2.1). The KD-HMICT group displayed a greater improvement in VO2peak compared to the KD-NMICT (p <0.05, d = 1.0). Conclusion: In overweight young adults, a short-term ketogenic diet is an effective strategy for improving body composition. Additionally, combining MICT with hypoxia provides further benefits on weight loss and cardiorespiratory fitness compared to normoxia. |
