This project will determine the independent and combined effects of aerobic exercise and time restricted fasting on cardiovascular risks among sedentary middle-aged and elderly adults. The online intervention period will be eight weeks. Before and after the intervention, arterial stiffness, cardiac autonomic nervous, body composition, glucolipid metabolism, sleep and eating habits, inflammatory reaction, sedentary behavior and physical activity level will be measured and compared between groups who are doing either aerobic exercise, time restricted fasting, both aerobic exercise and time restricted fasting, or who are in a control group. Adverse reaction, sleep and eating quality, life quality and adherence to the interventions and hunger/satiety will also be measured.

| Lean body mass | In kg | From baseline to after 8 weeks intervention |
| Body mass Index | In kg/m^2 | From baseline to after 8 weeks intervention |
| Body fat percentage | In percent of total body mass | From baseline to after 8 weeks intervention |
| Diet habits | Self-reported: diet habits were assessed using the Adult Eating Behavior Questionnaire (AEBQ). With higher scores indicating worse eating habits (represented by emotional over-eating and emotional under-eating) or better dietary (represented by food responsiveness, enjoyment of food, satiety responsiveness, food fussiness and slowness in eating). | From baseline to after 8 weeks intervention |
