Participants will be grouped into two cohorts determined by whether they receive palbociclib or alpelisib as part of their breast cancer treatment and then receive a 12 week prolonged nightly fasting plus exercise program consisting of:

* Prolonged overnight fasting: Not consume any calorie-containing food/drinks after 8pm, waiting a minimum of 13 hours after their last meal of the day before eating the next day, target goal of fasting at least 6 days a week, daily record of first and last meals
* Exercise Program: Coach provided at-home, personalized exercise regimen with target goal of 120 minutes of moderate-intensity aerobic activity each week as well as two 30-45-minute virtual strength training classes per week, receive fitbit for exercise and heart rate monitoring, weekly telephone-based support sessions with coach.

This research is evaluating the impact of a 12-week prolonged nightly fasting (POF) and exercise intervention on metabolic markers and patient reported outcomes in women with metastatic breast cancer (MBC) initiating endocrine therapy in combination with palbociclib or alpelisib.

This is single-arm feasibility pilot study exploring whether a combined prolonged nightly fasting (POF) and exercise program could impact hyperglycemia and other adverse metabolic consequences of PI3 kinase inhibitors in women with metastatic breast cancer (MBC).

Women who exercise regularly and who have lower levels of blood sugar and metabolic hormones like insulin have a lower risk of developing breast cancer. Some evidence also suggests that exercise and metabolism are related to cancer recurrence in women who are diagnosed with breast cancers that can be removed with surgery, but less is known about how exercise and metabolic factors are related to cancer progression in women whose cancer has advanced beyond the breast and underarm lymph nodes. This study is designed to look at the effects of exercise combined with prolonged nightly fasting (having a longer time between dinner and breakfast the next day), on blood sugar and hormones that control metabolism. This study looks to provide important information about whether making these kinds of changes is possible for women living with advanced breast cancer and will explore how making these changes effects blood sugar and hormone levels in women taking different kinds of treatments for advanced breast cancer.

The research study procedures include screening for eligibility, a baseline visit to collect information about diet and exercise habits, a baseline blood draw, participation in a 12-week diet and exercise program, and a follow up visit and blood collection at the end of the diet and exercise program.

Participants will be in this research study for up to 14-weeks, including the baseline and end of study visits to collect study measures.

It is expected that about 30 people will take part in this research study

Feasibility of Fasting & Exercise in Pts With HR+ MBC

Pilot Study of the Impact of a Combined Intermittent Fasting and Exercise Intervention on Metabolic Markers in Patients With Advanced, Hormone Receptor Positive Breast Cancer

The Dana-Farber / Harvard Cancer Center encourages and supports the responsible and ethical sharing of data from clinical trials. De-identified participant data from the final research dataset used in the published manuscript may only be shared under the terms of a Data Use Agreement. Requests may be directed to: \[contact information for Sponsor Investigator or designee\]. The protocol and statistical analysis plan will be made available on Clinicaltrials.gov only as required by federal regulation or as a condition of awards and agreements supporting the research.

The primary objective is to evaluate the feasibility of the intervention. Feasibility will be defined by the rate of enrollment and the intervention will be considered feasible if at least 80% of planned participants are enrolled within 12 months of study activation.

Feasibility will additionally be defined by participants achieving POF intervention goals on 70% of days by week 12.

Feasibility will also be defined by at least 70% of participants achieving 120 minutes of aerobic exercise plus 2 strength training classes per week by week 12.

We will evaluate changes in fasting glucose, insulin, insulin resistance, hemoglobin A1c and other metabolic biomarkers in study participants between the baseline and end-of-intervention blood draws.

Quality of life will be evaluated for participants at baseline and at the end of the intervention using the EORTC QLQ C-30, sleep quality will be assessed via the Pittsburgh Sleep Quality Index (PSQI). Additional patient reported outcomes include the PRO-CTCAE, the 7-Day Physical Activity Recall and the 24-Hour Dietary Recall. We will assess changes in these measures between baseline and week 12 for study participants.

We will explore potential differences in changes in metabolic markers over the course of the 12-week POF and exercise intervention by treatment group (alpelisib vs palbociclib).

The prolonged nightly fasting (PROFAST) intervention involves gradually working up to a 14-hour fast during the nighttime hours. Participants will be supported by means of calls with a health coach during the first 4 weeks of the study. Participants will also be asked to use a text messaging platform to record their first and last meal of the day, and will receive personalized feedback based on the meal times they record via the text messaging system. The text messaging system will be used throughout the duration of the study.

For participants randomized to the control group, an introductory session with a health coach and educational information will be provided. Participants will also receive one email and one text message per week with tips on healthy living during the 4 months of the study

This is a 4-month randomized trial of a prolonged nightly fasting intervention (PROFAST) in 40 overweight and obese individuals with monoclonal gammopathy of undetermined significance (MGUS), smoldering multiple myeloma (SMM), and smoldering waldenstrom macroglobulinemia (SWM). The purpose of this study is to understand if fasting for a prolonged period of time during the nighttime hours is a strategy to prevent overweight and obese individuals from developing blood cancer.

Participants will be randomized into the following two groups:

* Group A: PROFAST intervention for 4 months
* Group B: Healthy Lifestyle Control group for 4 months

The purpose of this research study is to learn if fasting for a prolonged period of time could be used in the future to help improve body composition and prevent blood cancer in overweight and obese individuals with MGUS, SMM, and SWM. Multiple myeloma is a cancer of the plasma cells, which is an important part of the immune system. Participants with active multiple myeloma generally require treatment. There are currently no approved therapies or prevention strategies for smoldering multiple myeloma or monoclonal gammopathy of undetermined significance.

The National Cancer Institute of the National Institutes of Health is supporting this research study by providing funding.

This research study is a 4-month randomized trial of prolonged nightly fasting (PROFAST). It is expected that about 40 people will take part in this research study. The total study duration is 4 months.

Participants in the study will be randomized, in equal numbers to either the nightly fasting intervention group or a control group.
