BIG MACS Diet for Colon Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores a special diet called the BIG MACS Diet, designed to aid individuals undergoing surgery for colon cancer. Researchers aim to determine if consuming more gut-friendly foods before and after surgery can enhance recovery. Participants will either follow the new diet plan or adhere to standard nutrition advice. The trial seeks individuals with stage 1-3 colon cancer who are about to undergo surgery and can meet the study's dietary and visit requirements. As an Early Phase 1 trial, this research focuses on understanding the diet's impact on recovery, offering participants an opportunity to contribute to groundbreaking nutritional science.
Do I need to stop my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the study team or your doctor.
Is there any evidence suggesting that the BIG MACS Diet is likely to be safe for humans?
Research has shown that diets high in fiber, like the BIG MACS Diet, are linked to a lower risk of colorectal cancer. Studies have found that more fiber and certain foods, like yogurt, can help reduce the risk of colon cancer. This suggests that the BIG MACS Diet, which aims to increase certain carbohydrates that support gut health, might be helpful.
Since the BIG MACS Diet is being tested in an early phase of clinical trials, clear information on its safety is not yet available. Early-stage trials mainly focus on tolerance, so researchers are checking for any negative reactions or side effects.
In summary, while positive evidence exists for diets similar to the BIG MACS Diet, the specific safety of this diet is still under study in this early trial. Participants' feedback will be crucial in determining how well the diet is tolerated.12345Why do researchers think this study treatment might be promising?
Researchers are excited about the BIG MACS Diet for colon cancer because it offers a dietary approach rather than relying solely on traditional treatments like chemotherapy and radiation. Unlike standard nutritional advice, which typically focuses on basic dietary guidelines and protein shakes, the BIG MACS Diet is specifically structured to be followed both before and after surgery, potentially enhancing recovery and outcomes. This unique focus on nutrition as a significant part of cancer care could lead to a better quality of life and improved recovery times for patients.
What evidence suggests that the BIG MACS Diet might be an effective treatment for colon cancer?
Research has shown that dietary changes can affect colon cancer outcomes. Increasing fruit and vegetable intake while reducing meat and sweets can lower the risk of colorectal cancer. In this trial, participants will follow different diet plans. One group will adhere to the BIG MACS Diet, which aims to improve gut health by increasing certain carbohydrates that support beneficial gut bacteria. This approach might aid recovery from colon cancer surgery. Early studies suggest that following this diet before and after surgery could lead to better results. Another group will receive standard nutrition advice. Although specific data on the BIG MACS Diet's effectiveness is still being gathered, the concept is based on evidence linking diet to cancer outcomes.12678

Excluded are those with significant health issues like anemia or liver problems, BMI <20 or >40, psychiatric conditions affecting adherence, history of substance dependency within five years, certain surgeries or diseases (like IBD), and pregnant/nursing individuals.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Pre-surgery Diet
Participants follow either the standard diet or the BIG MACS Diet with one protein shake per day for 4 weeks prior to surgery
Post-surgery Diet
Participants continue the BIG MACS Diet for an additional four weeks after surgery, with solid food reintroduction as early as tolerated
Follow-up

What Are the Treatments Tested in This Trial?
Interventions
- BIG MACS Diet
Trial Overview
The BIG MACS Diet aims to optimize gut microbiome before colorectal surgery by providing more microbiota accessible carbohydrates compared to a standard diet. The goal is to see if this special diet improves patient outcomes after surgery.
How Is the Trial Designed?

Treatment groups
Experimental Treatment
Active Control
Participants will be instructed to consume the study diet, referred to as the 'BIG MACS Diet' and one protein shake per day for 4 weeks prior to surgery (SOC). Following surgery, participants will continue to follow the BIG MACS Diet for an additional four weeks, with solid food reintroduction after surgery as early as tolerated.
Participants receiving only standard of care (SOC) nutrition advice, which is SOC Dietary Instructions, as provided by routine surgical consults and one protein shake per day for 4 weeks prior to surgery (SOC).
