Energy balance
Behaviorally based weight loss interventions (diet and/or physical activity) produce statistically significant weight loss (mean ≥5% of initial body weight) in overweight or obese women with breast cancer, with no serious adverse events reported.
If you are a breast cancer survivor who is overweight, a structured program focusing on diet and exercise can help you lose weight safely. Most programs last 6-12 months and involve regular check-ins with a professional. You can expect to lose at least 5% of your body weight, which is associated with better health outcomes.
Statistically significant within-group weight loss was observed over periods of 2 to 18 months in 13 of the 14 trials, with six randomized and two single-arm trials observing mean weight loss ≥5%... The studies included in this review suggest that weight loss is feasible to achieve and is safe in women following treatment for breast cancer.
Why this rating
Systematic review of multiple RCTs and single-arm trials, but individual studies had high or moderate risk of bias and small sample sizes.
