A popular ‘healthy’ snack could be sabotaging your diet and weight loss efforts, according to an immune health specialist.

Dr Jia-Yia Liu, an expert in immune and wellness who works on the front line of acute medical care and lectures at a leading medical school, shares health advice on her YouTube channel “Healthy Immune Doc,” and said that some fruity snacks are among the “worst foods that sabotage your diet.”

The doctor pointed out that fruity yoghurts and fruit bars – a staple for many slimmers – can actually be major culprits due to their high added sugar content.

“Added sugar raises your blood sugar and insulin levels, which makes you pack on fat,” Dr. Liu warned. She explained that eating sugary foods isn’t a problem if you exercise, but if you don’t “use up your sugar”, it can be stored as weight.

The expert said: “Insulin is a natural hormone that helps you gain weight by storing calories into fat. Both proteins and sugars can stimulate the release of insulin, but fat in the muscle or liver prevents the normal action of insulin.”, reports Gloucestershire Live.

She concluded by stating, “Fat makes the tissue insensitive to insulin and this phenomenon is called insulin resistance.”

Dr. Liu highlighted that added sugars are not just limited to the white granules we’re familiar with, but also include honey, maple syrup, agave juice, brown sugar, and fructose. Regardless of their form, these sugars can wreak havoc on our metabolism when consumed in large quantities.

The doctor also raised a red flag about the sugar content in flour, revealing it contains “more sugar than table sugar” due to its high glucose molecule content.

For those looking to slim down, Dr Liu warned against excessive intake of fructose, which can be harmful to the liver. If you’re partial to a fruit bar snack, she suggested popping them in the fridge or freezer overnight before eating.

This simple trick reduces their sugar content by causing the amylopectin to bind with another starch called amylose, creating resistant starch. “Resistant starch won’t raise your blood sugar and is healthy for the body,” she explained.

A study published in the National Library of Medicine praised resistant starch for its potential weight loss benefits, stating it “has many attributes which could promote weight loss and/or maintenance.”

These benefits range from increased release of gut satiety peptides, enhanced fat oxidation, and lower fat storage in adipocytes (cells that store energy as fat), to preservation of lean body mass. For optimal weight loss results, Dr Liu advised choosing whole fruits over processed foods containing fruit.
