A basic premise regarding weight gain centers around calorie consumption. When more calories are consumed than are burned, weight is gained, and most of the excess calories are stored as fat. Since people are malabsorbing less and eating more, they are putting on weight. Again, when calories are not burned, they are stored as fat. It is logical that when individuals eat more and absorb more calories while maintaining the same level of inactivity, fat is gained.
Fear also plays a role.
Many of my clients have expressed a certain amount of fear around losing weight. This is completely false. Muscle is what the virus prefers. It does not matter how much fat is on the body, the virus will attack muscle stores before fat stores. So it makes sense to increase muscle rather than fat.
