Part 3/10:
For instance, consider consuming a high-calorie item, such as a 1,000-calorie milkshake. If only a fraction of that energy is utilized in the following time frame, the body stores the remaining calories as fat. This principle applies universally across all foods, emphasizing that it's not solely about fat consumption but the excess energy intake.
The Role of Insulin
One crucial factor in fat storage involves the hormone insulin. Insulin facilitates glucose uptake by cells, enabling energy use or storage. When insulin levels are high, fat burning is effectively suppressed as the body prioritizes glucose. In the case of individuals with Type 1 diabetes, who cannot produce insulin, despite having high blood sugar, they do not gain weight due to the absence of insulin for fat storage.
