“…Nevertheless, the results indicate that for all subjects, physical performance improved during the intervention and was not compromised by the low (LCD) or very low (KD) carbohydrate content of their diet. This is in accordance with published data from healthy subjects and athletes, who also performed well under LCD and KD regimes [65][66][67][68][69]. In principle, lowering carbohydrate intake could lead to intramuscular glycogen depletion and subsequent impairment of maintaining higher exercise workloads.…”

Breast cancer (BC) patients often ask for a healthy diet. Here, we investigated a healthy standard diet (SD), a low carb diet (LCD), and a ketogenic diet (KD) for BC patients during the rehabilitation phase. KOLIBRI was an open-label non-randomized one-site nutritional intervention trial, combining inpatient and outpatient phases for 20 weeks. Female BC patients (n = 152; mean age 51.7 years) could select their diet. Data collected were: Quality of life (QoL), spiroergometry, body composition, and blood parameters. In total 30, 92, and 30 patients started the KD, LCD, and SD, respectively. Of those, 20, 76, and 25 completed the final examination. Patients rated all diets as feasible in daily life. All groups enhanced QoL, body composition, and physical performance. LCD participants showed the most impressive improvement in QoL aspects. KD participants finished with a very good physical performance and muscle/fat ratio. Despite increased cholesterol levels, KD patients had the best triglyceride/high-density lipoprotein (HDL) ratio and homeostatic model assessment of insulin resistance index (HOMA-IR). Most metabolic parameters significantly improved in the LCD group. SD participants ended with remarkably low cholesterol levels but did not improve triglyceride/HDL or HOMA-IR. In conclusion, both well-defined KDs and LCDs are safe and beneficial for BC patients and can be recommended during the rehabilitation phase.

“…Nevertheless, our results indicate that for all subjects, physical performance improved during the intervention and was not compromised by the low (LCD) or very low (KD) carbohydrate content of their diet. This is in accordance with published data from healthy subjects and athletes, which also performed well under LCD and KD regimes [18][19][20][21]. While some studies showed a negative impact when switching to LCDs or KDs on physical performance in the short term (21-30 days; [22]) and up to 10 weeks [23], the duration of 20 weeks in our study allowed the patients to adapt to the profound change in energy metabolism.…”

Background: Breast Cancer (BC) patients often ask for a healthy diet. Here, we compared three different diets which could support BC patients during the rehabilitation process: a healthy standard diet (SD), a low carb diet (LCD) and a ketogenic diet (KD).Patients and Methods:KOLIBRI was a one-site nutritional intervention trial, combining inpatient and outhouse phases for 20 weeks. Female BC patients (n=152; mean age 51.7 years) could select their diet. Data collected were: quality of life (QoL), spiroergometry, body composition, blood biochemistry. 30, 92 and 30 patients started the KD, LCD and SD, respectively. Of those, 20, 72 and 25 completed the final examination.Results:Patients rated all diets as feasible in daily life. No adverse effects occurred in any diet group. KD offered the highest amount of energy and protein. All groups improved in QoL, body composition and physical performance. KD was superior in improving fatigue, insomnia and physical functioning. KD participants finished with the best physical performance and the highest muscle/fat ratio. Despite their increased cholesterol, KD patients had the best triglyceride/HDL ratio and HOMA-IR. Most metabolic parameters significantly improved in the LCD group. SD participants ended with remarkably low cholesterol levels, but did not improve triglyceride/HDL or HOMA-IR.Conclusions:A well-defined KD and LCD are safe and beneficial for BC. Both diets could thus be recommended for patients wanting to self-support their rehabilitation process.Trial registration IDNCT02092753 Protocol Registration date:02/26/2014Ketogenic Or LOGI Diet In a Breast Cancer Rehabilitation Intervention (KOLIBRI)URL: https://clinicaltrials.gov/ct2/show/NCT02092753?cond=KOLIBRI&draw=2&rank=1

“…The last decade has been characterized by the search for alternative dietary ways to achieve optimal body composition while maintaining or improving physical fitness and sports performance to promote healthy lifestyle and prevent chronic diseases [ 1 , 2 ]. Current trends in sports nutrition are increasingly reaching for the minimization of the carbohydrate component with ketogenic diet becoming a very popular approach, in particular in endurance athletes [ 3 , 4 ].…”

The Influence of Cyclical Ketogenic Reduction Diet vs. Nutritionally Balanced Reduction Diet on Body Composition, Strength, and Endurance Performance in Healthy Young Males: A Randomized Controlled Trial

(1) Background: The influence of ketogenic diet on physical fitness remains controversial. We performed a randomized controlled trial to compare the effect of cyclical ketogenic reduction diet (CKD) vs. nutritionally balanced reduction diet (RD) on body composition, muscle strength, and endurance performance. (2) Methods: 25 healthy young males undergoing regular resistance training combined with aerobic training were randomized to CKD (n = 13) or RD (n = 12). Body composition, muscle strength and spiroergometric parameters were measured at baseline and after eight weeks of intervention. (3) Results: Both CKD and RD decreased body weight, body fat, and BMI. Lean body mass and body water decreased in CKD and did not significantly change in RD group. Muscle strength parameters were not affected in CKD while in RD group lat pull-down and leg press values increased. Similarly, endurance performance was not changed in CKD group while in RD group peak workload and peak oxygen uptake increased. (4) Conclusions: Our data show that in healthy young males undergoing resistance and aerobic training comparable weight reduction were achieved by CKD and RD. In RD group; improved muscle strength and endurance performance was noted relative to neutral effect of CKD that also slightly reduced lean body mass.
