How does someone gain weight
By having a large intake of fatty foods or an overabundance of non-used calories, the adipose cells (typically white) will absorb the fatty acids and triglycerides from the bloodstream and will expand. This appears as weight gain, but also noticeably enlarged features
How does someone lose weight
By increasing the ratio between energy output and energy consumption, in favor of the output, the white cells will release stored fatty acids for energy. Over time, this results in weight loss and a slimmer appearance.
