If a person is eating a healthy diet and exercising five days a week, they may expect to see results, said Davoncie Granderson, M.S.Ed, ACE CPT, an exercise physiologist at Northwestern Medicine Kishwaukee Health & Wellness Centre. She said to keep in mind that genetics and diet play a large role in weight loss.
Christopher McGreer, MS, NSCA CSCS, personal training coordinator at Northwestern Medicine Delnor Health & Fitness Centre, agreed and added that "five days a week of exercise doesn't automatically ensure weight loss." The type and intensity of exercise a person is doing will significantly impact weight.
Another important point to note is that a person could very well maintain or even gain weight, said Kate Huether, MD, if the person eats additional calories. It's also important to note that you can lose fat and your body could look leaner but your weight could stay the same or increase if you're gaining muscle from exercise.
