Summary

Primary objective: To assess the effects of a modified plant-based Mediterranean diet (vegeterranean diet), circuit resistance training (CRT) and empagliflozin alone or in combination on metabolic and physical function in elderly subjects with type 2 diabetes. The rationale for this study is to assess three interventions associated with a negative energy/caloric balance (increased caloric use in exercise, caloric restriction in the vegeterranean diet and caloric wasting by glycosuria with empagliflozin), their interaction and effect on body composition and physical function. Methods and analysis: One hundred men and women ≥ 65 years of age with type 2 diabetes, and low levels of physical activity will be randomized (1:1:1 manner, gender-stratified) for 10 weeks to one of 3 parallel arms: CRT consisting of 3 home sessions/week; ad-libitum plant-based Mediterranean diet (limited consumption of eggs, dairy and fish, avoidance of red meat and poultry) or empagliflozin 10mg/day. After 10 weeks CRT will be added to the empagliflozin or diet arms for an additional 10 weeks. Allocation concealment and blinding of primary outcome assessors will be implemented. Efficacy will be determined by assessment of lean body mass, body weight, fat mass %, sarcopenia measures (such as strength and physical function), HbA1c and blood pressure as well as other outcomes (both objective and subjective). Safety will be evaluated by routine monitoring of adverse events. This study was approved by the Tel-Aviv Sourasky Medical Center Institutional Review Board

Interventions

Type	Name	Description
BEHAVIORAL	Circuit resistance training (CRT)	Subjects will be allocated to CRT which consists of 10 resistance exercises for different body parts (=1 circuit) repeated 12-15 times, using modest weights (approximately 40-60% of one repetition maximum, RM). Each exercise is expected to be completed within 30-40 sec. The participant will move quickly (within 15-30 seconds) from one exercise to the next. The circuit will be repeated up to three times depending on the week of intervention. Thus, it will take about 30 min to complete an exercise session. For a summary of articles on CRT in older adults based on a meta-analysis, we performed please see: Circuit resistance training is an effective means to enhance muscle strength in older and middle-aged adults: A systematic review and meta-analysis.

BEHAVIORAL	Vegeterranean diet (V-Med diet)	The modified V-Med diet will be considered as ad-libitum (using fat sources) aimed for a minimum of 1 gr/kg/day of protein, limiting carbohydrates: 3 servings for men and 2 servings for women per main meal and 1 serving per intermediate meal for both genders. Subjects will be asked to avoid red meat and poultry completely and the consumption of dairy and eggs products will be limited to 2 servings per day. 2-3 servings of fish should be consumed during the week. The rest of protein consumption will be recommended from legumes sources. The target legume consumption will be 1.5 cup per day (2 servings per day) of cooked beans, chickpeas, lentils and/or using pulses-based flour or pulses-based bread. Consumption of whole grain carbohydrate foods will be recommended.
DRUG	Empagliflozin 10 MG	Subjects allocated to empagliflozin will be asked to add empagliflozin 10mg, preferably in the morning, to their medication regimen. Subjects will be monitored for adverse events including hypoglycemic events during all study visits.
