How’s your weight loss journey going? Is it mediocre at best? Weight loss is sometimes portrayed as a simple equation of calories in and calories out, but it is actually rather complex. According to one team, blood sugar fluctuations can also have a major impact on weight. For those who are unaware, blood sugar levels are regulated by two hormones called insulin and glucagon, which promote energy storage and transportation, respectively. People with type 2 diabetes, for instance, are more likely to develop insulin resistance, which raises blood sugar levels and eventually leads to weight gain.
