Peptides for Weight Loss [Ask a Nutritionist]

peptides for weight loss

Many of you know that proteins are a calorie source that the body converts into muscle instead of fat making peptides effective for weight loss.

Peptides are proteins that break down into small chains of amino acids. Amino acids are the building blocks of protein, and peptides are simply a chain of proteins.

Peptides have become a popular weight loss supplement in recent years, as they work to help break down fat cells and promote weight loss.

In this article, we will discuss peptides and how they work to promote weight loss.

We asked several experts and certified nutritionists their thoughts on using peptides for weight loss.

The science behind Peptide Therapy

The benefits of peptides for weight reduction are nearly endless, and they prove to assist with the management of obesity. Peptides produce more Human Growth hormones in your body, which is why they’re so effective in helping you slim down. They also enable the management of high blood sugar levels, which can cause diabetes and other health issues.

Peptides are small pieces of protein that execute various functions during natural bodily processes. Your body naturally releases growth hormones when you train or exercise without any help.

Growth Hormone Releasing Hormone (GHRH) levels naturally decrease as we age. Peptide therapy encourages your body to produce and release human growth hormone (HGH).

Ipamorelin and Sermorelin are two peptides that help signal system changes, including human growth hormone (HGH) release. This hormone is necessary to maintain bone and muscle strength, repair tissue damaged by injury or illness, and combat disease. It also has a long list of anti-aging effects, including an increase in lean muscle mass, a decrease in wrinkles and age spots, and improved sleep quality.

peptides can help you lose weight by:

  • Burning fat cells
  • Reducing inflammation
  • Boosting metabolism
  • Increasing energy levels
  • Enhancing exercise performance

All of these effects work together to help you lose weight.

Common Peptides for Weight Loss

Sermorelin, Ipamorelin, and CJC-1295 are the most popular peptides.

The body produces growth hormone “boosters” naturally. Growth hormone has a significant influence on the immune system and functionality.

Long-term delivery of peptides enhances your immunity to sickness, viruses, and all types of bacteria.

The most common peptides prescribed by doctors include:


A peptide that helps release growth hormone is commonly used for anti-aging purposes. Sermorelin has been shown in several Harvard University studies to reduce abdominal fat in obese patients long-term. Many studies make Sermorelin the best peptide option for people looking to cut weight.

A team at McGill University also found the most promising between the peptide Sermorelin and abdominal visceral fat loss to date.

This appears to be the most promising strategy to date for a safe, effective method of reducing excess visceral fat deposits and improving lipid abnormalities in HIV-infected patients, thereby improving their risk for cardiovascular disease,” says Steven Grinspoon of the MGH Neuroendocrine Unit and Program in Nutritional Metabolism, the report’s senior and corresponding author.



A peptide that helps release growth hormone can be used for bodybuilding and anti-aging purposes. Several studies have shown Ipamorelin to help with weight loss and muscle gain.


A peptide helps release growth hormone and can also be used for anti-aging purposes. CJC-1295 has been shown to help with weight loss in several studies, as well as increase lean muscle mass

Side Effects of Peptides

Side effects of peptides are known to be relatively mild and rare.

The most common peptide side effects include:

  • Headaches
  • Nausea
  • Fatigue
  • Dizziness

Peptides appear to be one of the safer options for supplementation on the market.

Ask a Nutritionist: Peptides and Loss of Weight

Lindy Health reached out to several experts and nutritionists to get their take on using peptides in weight loss transformations.

Many experts had differing views, but all seemed to think peptides showed various levels of promise as a method for weight control.

“Peptides aid in helping the body release specific hormones at ideal times for weight loss. While peptides can aid in weight loss, no product or routine can make up for a bad diet or lifestyle.”

Trista Best, MPH, RD, LD

“Taking peptides is like taking pieces of proteins. Proteins are helpful in weight loss because they are a calorie source that can be turned into muscle or organ tissue when not burned. Rather than take peptides, it would be better to take amino acids so that the body can assemble what proteins it needs rather than break down the peptides into amino acids and then build what it needs.”

Robert S. Herbst, Drug Testing Supervisor Rio Olympics

“Although peptides have become an increasingly popular weight loss supplement, and there is some scientific evidence backing their fat-reducing effects, these studies have been limited to the medical and research fields. There is no way to determine an effective dose, so I would hesitate to describe them as effective outside the realm of anecdote.”

Dan Gallagher, ISSA Certified Nutritionist

Are Peptides Steroids

Peptides have attracted a lot of attention due to their potential for fat loss.

are peptides steroids

Medical professionals now provide peptide supplements through injections, sprays, creams, and pills.

Although peptides are perfectly permissible, authorities have prohibited their use in competitive sports due to the risk of unfair advantage.

Although this is an oversimplification, it should be emphasized that peptides are not steroids or testosterone.

Peptides are not simply a miracle drug. Peptides are a tool, and much like a diet, going to the gym must be used in conjunction with an overall healthy lifestyle. Peptides will not work if an individual is eating 3000 calories a day and not working out.

That said, peptides can be a helpful tool for weight loss when used correctly in conjunction with other healthy lifestyle choices.

If you are looking for help with peptide supplementation, your nutritionist or doctor is your best bet.

Peptides: The Verdict

We believe that peptides may be an excellent option for the reduction in body weight along with gaining an increase in lean muscle mass. Peptides can help with weight loss by burning fat cells, reducing inflammation, boosting metabolism, and increasing energy levels.

If you want to go about losing weight the old fashion way there are also programs online such as Lindy Health and the Fit Father Project.

While the studies are not plentiful, the studies that reputable organizations have performed do show promise.

If you are thinking about using peptides for weight loss, you must speak with a certified nutritionist or doctor first. Peptides are a powerful tool that can help you lose weight, but you should not use them without the supervision of a medical professional.

After several near-death surgeries and a heart attack at 29, I decided to get serious about my health and went from 278lbs to 181lbs in only six months. How? I built an entire team, including a personal trainer, nutritionist, psychologist, physical therapist, and sports masseuse. Having the same team as Hollywood stars allowed me to reach my goals fast and produce insane results.
