Semaglutide Study

Over 1900 study participants who didn’t have diabetes and had a BMI of 30 or higher, were involved in a 2021 double-blind clinical trial on the safety and effectiveness of semaglutide.3 After taking semaglutide weekly injections for approximately 17 months, the average change in body weight was 14.9%, or around 30 pounds. The study authors concluded, “In participants with overweight or obesity, 2.4 mg of semaglutide once weekly plus lifestyle intervention was associated with sustained, clinically relevant reduction in body weight.”3

Tirzepatide

Taking tirzepatide once a week promotes weight loss and treats type 2 diabetes. Tirzepatide is often prescribed in combination with a healthy diet and exercise regimen. 

Benefits of Tirzepatide

The benefits of tirzepatide include:

  • Decreasing appetite and food cravings
  • Slowing down digestion 
  • Increasing a feeling of fullness
  • Promoting weight loss
  • Increasing insulin levels (for lowering blood sugar)
  • Reducing bad (LDL) cholesterol and triglycerides
  • Reducing liver fat

Note, that tirzepatide and other GLP-1 agonists have a boxed warning; this is the FDA’s most serious warning about possible side effects of a drug. The warning must be printed on the drug’s label, informing patients of the risk. The boxed warning reads:

WARNING: RISK OF THYROID C-CELL TUMORS

GLP-1 agonists have been found in animal studies to cause a type of thyroid tumor called “C-cell tumors.”  This includes medullary thyroid carcinoma (MTC). It’s unknown whether tirzepatide (and other GLP-1 agonists) causes this type of cancer in humans, but due to the potential risk, people with MTC or a family history of MTC should not take tirzepatide. 

Tirzepatide Studies

A 2023 meta-analysis (i.e., a type of study that combines results from several different research sources and identifies trends), discovered that depending on the dose they were taking, patients lost between 8 and 12 percent of their body weight (17-26 pounds) after taking tirzepatide. 7

LDN Boost/Naltrexone Study

A 2020 review study of 191 research articles and 10 studies concluded that in most of these studies, a primary outcome of naltrexone/bupropion, prescribed for obesity, was at least a 5% to 10% weight loss.8  The study authors wrote, in conclusion, our systematic review suggests that naltrexone/bupropion treatment is effective in weight loss amongst overweight subjects. The naltrexone/bupropion treatment was well tolerated by the patients, and side effects were rarely reported.” More research is needed to evaluate the potential weight loss benefits of low-dose naltrexone.
