British researchers found that overweight people have a dulled sensitivity to tasting sweets and a liking for sweet food. In the same study, healthy and fit people who began to drink 2 soft drinks a day had dulled taste buds and sugar cravings after only 4 weeks.
“Our subconscious drive plays a huge role in what food choices we make, and as overweight people feel hungrier they are more affected by their subconscious drive for sweet high calorie foods,” wrote the study. (8)
Similarly, a 2016 study found that after a month of cutting down on dietary sugar, the experimental group found they were more sensitive to sweet flavors. Therefore, if you cut down on sugar, food will begin to taste sweeter without it. (9) Sweet!
6. Foggy Brain
A study published in the journal Neuroscience found that mice fed a diet “similar in composition to the typical diet of most industrialized western societies rich in saturated fat and refined sugar” experienced a reduced brain function in only 2 months.
That’s because high amounts of sugar affect proteins and neurotransmitters in the brain that are responsible for learning and memory. (10) In short: sugar makes you more stupid.
7. Skin Problems
Collagen is the most prevalent protein in the body and is responsible for skin elasticity. By nature, sugar molecules bind to collagen and help collagen cells move around.
