In another surgery, the stomach is attached to the middle of the small intestine. This bypasses a large part of the small intestine and reducing the amount of calories and nutrients absorbed into the body. Roux-en-Y gastric bypass (RYGB) involves stapling the stomach to create a small pouch. The smaller stomach is attached directly to the middle of the small intestine. This allows food to bypass much of the stomach and the first section of the small intestine. It limits the amount of food that you can eat and reduces the amount of calories and nutrients that are absorbed into the body. Previous.
I've seen male competitors eat fewer than 1,800 calories trying to reduce their body fat. This is not the way to get shredded. If you cut your calories this much, you will end up losing significant lean muscle mass and severely damaging your metabolism.
The more lean muscle mass you have, the more calories you burn. Muscle tissue burns more calories than fat tissue, and the more muscle you have, the more your metabolism increases. This means you burn more calories during activities as well as when you are at rest. If you have weight loss goals, a combination of cardio and strength training will up your metabolism, create more muscle mass and help you burn calories and fat.
