How Collagen Supports a Healthy Metabolism?

Collagen for weight loss supplement, a helpful bolster for our bodies, offers a variety of opportunities to have a healthy metabolism. Here are the 5 most significant benefits of them.

  1. Accelerates metabolism and promotes fat burning: Glycine, an amino acid found in abundance in collagen, aids in the production of more human growth hormone.
  2. Reduces inflammation: Because of its anti-inflammatory qualities, collagen helps lessen inflammation in the body, which in turn supports metabolism and weight loss.
  3. Satiates: Reducing hunger, cravings, and blood sugar fluctuations, collagen aids in weight control by satiating food cravings.
  4. Improves gut health: Glycine, found in collagen, promotes a balanced intestinal flora. Additionally, it supports a healthy gut barrier by strengthening the intestinal lining and preventing leaky gut.
  5. Builds lean muscle mass: Collagen is the protein needed to build and repair muscle tissue. It also supports healthy joints and connective tissue, which facilitates exercise and weight training. By aiding in the development and maintenance of muscle tissue, collagen also contributes to an elevated resting metabolic rate.

Appetite Control and Satiety with Collagen

Due to its high protein content, collagen can help manage appetite by enhancing feelings of fullness. Consuming collagen can prevent overeating from empty calories by making you feel full, which can reduce your overall calorie intake. This helps control hormones and appetite. For example, adding collagen to your morning coffee or smoothie can keep you fuller for longer. 

Collagen can also reduce appetite by stabilizing blood sugar levels. This can prevent overeating by reducing cravings and hunger. Collagen's low digestibility and capacity to retain water in the stomach increase the feeling of satiety by creating bulk. This is considered a strategy used in the treatment of obesity.

Research on "Does collagen help with weight loss?" is gaining more attention among health enthusiasts. After 12 weeks of taking 15 grams of collagen peptide pills daily, older persons saw a dramatic decrease in their body fat mass, according to a study in Clinical Nutrition Research (1). Compared to non-users, collagen users in the 74-person study showed a significant reduction in both total body fat mass and body fat percentage. Collagen is hard to digest and holds a lot of water. It also influences hunger hormones and increases feelings of fullness, which leads to these effects.    

Gut Health as a Foundation for Weight Loss

A healthy digestive system is essential for a successful weight loss journey. Your digestive and metabolic systems rely on a well-balanced microbiota, which in turn aids weight loss. Thanks to the amino acid glycine found in collagen, this mechanism can be supported: a balanced microbiota lowers the risk of obesity.

Collagen helps maintain a healthy intestinal barrier by fortifying the lining of the intestines. Thus, a strong intestinal barrier ensures that nutrients are properly digested and absorbed and prevents inflammation, and reduced inflammation plays an important role in weight management.

Furthermore, collagen balances the gut microbiota by increasing the number of beneficial bacteria and limiting the presence of harmful bacteria. This balance improves digestion and nutrient absorption, which supports weight loss. 

Collagen enhances the sensation of fullness by significantly retaining water, thus adding volume to the stomach. This feeling reduces the tendency to overeat and thus controls calorie intake. Its low digestibility also supports this effect. Finally, collagen can affect hunger hormones such as ghrelin. Lowering ghrelin levels helps reduce appetite and control weight. 

If you're still wondering, can collagen help you lose weight, it's worth looking into the latest research. Taking 20 grams of collagen supplements daily (for 12 weeks) was found to reduce weight, BMI (body mass index), waist circumference, fat mass, fatty liver index, and systolic blood pressure. These positive results were observed in overweight and obese individuals, according to the study in Nutrients (2).
