Is your Gut Effecting your Weight Loss?

We sat down with Gastroenterologist, Dr. Alasdair Patrick, to explore one reason some people find it harder to lose weight than others — the gut microbiome. While many factors contribute to weight challenges, emerging research shows our gut bacteria may play a bigger role than we think.

Why is weight loss easier for some people than others?

It's not always about willpower. Some people lose weight quickly and easily, while others struggle despite consistent effort. Emerging research points to the gut microbiome — the community of bacteria in your digestive system — as a key factor. It may influence how your body stores fat, manages blood sugar, and signals hunger.

So while many people lose weight by eating fewer calories and choosing nutrient-rich foods, others face an added hurdle: an imbalanced gut flora. If you're eating less than you burn but still not losing weight, your gut microbiome could be part of the picture.

‎What role does gut biodiversity play in metabolism?

People who struggle with weight loss often have less gut microbial diversity than those who lose weight more easily. Increasing the diversity and volume of beneficial bacteria may help improve metabolic function and support weight management.

‎Why does your gut impact weight?

‎Gut bacteria help digest food and, in doing so, release hormones known as gut peptides. These peptides signal the brain about hunger, digestion, and metabolism. A balanced microbiome supports healthy release of these hormones — shifting the balance toward burning energy rather than storing it.

How do Prebiotics help with weight loss?

Prebiotics — like Alleviate — offer several benefits for weight loss:

- Reduce hunger and cravings

Prebiotics feed beneficial bacteria such as Bifidobacteria and Lactobacillus. As these bacteria eat up the fibre, they produce short-chain fatty acids, which trigger hormones that help you feel full, and balance blood sugar.

Also, because fibre moves slowly through the digestive tract - you feel fuller for longer.

There's also evidence prebiotics may change how the brain responds to high-calorie foods, easing the "reward" signals that junk food triggers — so a healthier microbiome may mean fewer cravings in the first place.

- Boost metabolism

Prebiotics have been shown to improve insulin sensitivity and increase energy expenditure, supporting a more efficient metabolism.

- Support fat reduction and nutrient absorption

Prebiotic fibres can reduce fat absorption while improving the body's ability to absorb essential nutrients.

- ‎Strengthen the gut barrier

Fibre helps fortify the gut lining, reducing inflammation and supporting overall gut health.

Why Choose Alleviate?

Not all fibres are equal. Partially Hydrolysed Guar Gum (PHGG) stands out for its gut health and weight loss benefits. Research suggests PHGG can meaningfully reduce hunger and support healthier snacking habits, alongside encouraging results for supporting weight loss as part of a calorie-controlled diet.

With regular use, Alleviate supports a healthier gut, may increase biodiversity, ease cravings, manage hunger, balance blood sugar, and support metabolic efficiency — a useful addition to a weight loss programme, especially if you've found it hard to lose weight or keep results off.
