What Are Peptides?

Natural amino acids, known as peptides, are essential for building muscle, repairing tissues, and regulating hormones in the body. But the benefits of natural peptides do not stop there since they can also help you lose weight via several mechanisms, including:²

  • Enhancing metabolism levels to boost calorie-burning
  • Improving the production of hormones that influence weight loss
  • Boosting human growth hormone (HGH), which stimulates lean muscle growth
  • Transmitting signals to the body to burn fat in fat cells before burning calories from glucose
  • Influencing blood sugar levels
  • Decreasing appetite
  • Slowing stomach emptying, which causes a feeling of fullness

What Are Peptide Drugs?

Peptide drugs were first developed to treat diabetes because they lower blood sugar, but people began noticing how these medicinal weight loss peptides helped them lose weight. One group of drugs—glucagon-like peptide-1 (GLP-1)—results in dramatic weight loss.

However, successful weight loss from taking a peptide for weight loss can be influenced by several variables such as:

  • Type of diet
  • Lifestyle changes (e.g., diet and exercise)
  • Personal health history
  • Response to the medication

Best Peptides for Weight Loss

Several types of GLP-1 receptor agonists are currently prescribed for weight loss.

Semaglutide – This GLP-1 receptor agonist is one of the best peptides for weight loss. Semaglutide is used to treat type 2 diabetes; one form of semaglutide is used to treat obesity via a weekly injection. Semaglutide is a weight loss medication prescribed off-label (a drug that’s given for a condition other than what the FDA approves it for). Semaglutide lowers appetite, increases a feeling of fullness (satiety), and improves insulin sensitivity.*

*Increased insulin sensitivity allows the body’s cells to more efficiently utilize glucose, lowering blood sugar.

Liraglutide – Liraglutide is a GLP-1 receptor agonist given specifically for weight loss. Like semaglutide, liraglutide increases satiety, curbs appetite, and improves insulin sensitivity. As a once-per-day injection, liraglutide lowers appetite and helps promote weight loss and weight management for at least 12 months. Liraglutide is known to help keep the weight off for about a year, and its peak action occurs around week 60.⁴
