Plain language summary
Multiple sclerosis (MS) is a disease of the central nervous system. Dietary modification is emerging as a safe intervention to potentially modify disease course. The main aim of this study was to assess the safety and feasibility of an intermittent fasting diet in people with MS. Secondary outcomes explored the effects of calorie restriction (CR) diets on body weight and anthropometric characteristics as well as on patient-reported outcomes including fatigue, sleep and mood. The study is a pilot randomised controlled feeding study of three different types of diets. Each participant (n=36) was randomized to 1 of 3 diets: a control diet (placebo), a daily CR diet and intermittent CR diet. Results indicate that daily CR diet was associated with marginally greater weight loss than the intermittent CR diet. Both CR diets were associated with trends toward improvements in cardiometabolic outcomes. Furthermore, CR diets were associated with in improvements in emotional well-being. Authors conclude that CR and weight loss represent interventions for clinically relevant symptoms due to MS, such as emotional well-being, without adding meaningful risks or adverse outcomes.
Abstract
An intermittent fasting or calorie restriction diet has favorable effects in the mouse forms of multiple sclerosis (MS) and may provide additional anti-inflammatory and neuroprotective advantages beyond benefits obtained from weight loss alone. We conducted a pilot randomized controlled feeding study in 36 people with MS to assess safety and feasibility of different types of calorie restriction (CR) diets and assess their effects on weight and patient reported outcomes in people with MS. Patients were randomized to receive 1 of 3 diets for 8 weeks: daily CR diet (22% daily reduction in energy needs), intermittent CR diet (75% reduction in energy needs, 2 days/week; 0% reduction, 5 days/week), or a weight-stable diet (0% reduction in energy needs, 7 days/week). Of the 36 patients enrolled, 31 (86%) completed the trial; no significant adverse events occurred. Participants randomized to CR diets lost a median 3.4 kg (interquartile range [IQR]: -2.4, -4.0). Changes in weight did not differ significantly by type of CR diet, although participants randomized to daily CR tended to have greater weight loss (daily CR: -3.6 kg [IQR: -3.0, -4.1] vs. intermittent CR: -3.0 kg [IQR: -1.95, -4.1]; P = 0.15). Adherence to study diets differed significantly between intermittent CR vs. daily CR, with lesser adherence observed for intermittent CR (P = 0.002). Randomization to either CR diet was associated with significant improvements in emotional well-being/depression scores relative to control, with an average 8-week increase of 1.69 points (95% CI: 0.72, 2.66). CR diets are a safe/feasible way to achieve weight loss in people with MS and may be associated with improved emotional health.

Plain language summary
Physical activity has been shown to considerably reduce the burden of several non-communicable disorders (are diseases of long duration and generally slow progression), such as heart disease, stroke, diabetes, and breast and colon cancers. The aim of the study is to estimate the prevalence of physical activity among a mixed group of patients with psychiatric illnesses in Saudi Arabia. Furthermore, the study sought to evaluate the associations between physical activity, patients with different psychiatric diagnoses and the use of psychotropic medications. The study is a cross-sectional observational study that recruited 1185 patients seeking psychiatric advice, with an average age of 38.0±13.0 years. Results indicate a low prevalence of physical activity in a large, mixed sample of patients with psychiatric illnesses in both inpatient and outpatient settings in Saudi Arabia. Authors conclude that physical activity levels vary according to the type of psychiatric disease and the medications used. They outline that it is important to assess the physical activity status in patients with psychiatric illnesses and promote physical activity programs among psychiatric patients.
Abstract
OBJECTIVES To estimate prevalence of physical activity and its associations with various psychiatric disorders and the use of psychotropic medications. METHODS A cross-sectional observational study was carried out between July 2012 and June 2014. Patients were enrolled from a number of hospitals located in 5 regions of the Kingdom of Saudi Arabia. RESULTS A total of 1185 patients were included in current analysis: 796 were outpatients, and 389 were inpatients. Out of 1,185 patients, 153 (12.9%) were physically active. Much higher rates of physical activity were reported among males than females (15.9% versus 9.6%, p less than 0.001). According to the univariate analysis, higher rates of physical activity were positively correlated with primary bipolar disorders, the use of antianxiety medications and, to a lesser extent, use of antipsychotic medications, but they were negatively correlated with primary anxiety disorders, use of antidepressant medications, and use of multiple psychotropic medications. The associations between physical activity and primary bipolar disorders (odds ratio [OR]=2.47, p=0.002), use of antianxiety medications (OR=3.58, p=0.003), and use of multiple psychotropic medications (OR=0.33, p less than 0.001) remained significant after adjusting for demographic and clinical characteristics. CONCLUSION We report a variable but generally low prevalence of physical activity among a large, mixed sample of psychiatric patients in Saudi Arabia. These findings may highlight the importance of assessing physical activity status of psychiatric patients and the critical need for physical activity promotion programs among this group of disadvantaged patients.
