Nutritionist Degtyannikova: bananas, watermelons, mangoes, grapes and dates interfere with weight loss 
when losing weight. She also named the permissible amount of these products per day, RIA Novosti reports.
The specialist urged not to eat fruits with a high glycemic index: bananas, watermelons, mangoes, grapes and dates. According to her, they are prohibited when losing weight, because they interfere with this process. The nutritionist advised to eat no more than two fruits per day, sometimes this number should be limited to one.
“The glycemic index is the rate at which glucose enters the bloodstream in response to certain foods. The higher this indicator, the faster glucose enters the bloodstream, the stronger its jump will be. This means that the glycemic index characterizes the ability to stimulate the production of insulin – the main hormone that launches glucose into the cell, due to which we get energy, “explained Degtyannikova.
The medic added that” not everything is clear in the process of losing weight “. However, the reduction in sweet fruits lowers the number of triglycerides in the blood.
“Their high levels are associated with diabetes and metabolic syndrome, as well as when the adrenal glands are depleted, sugar can provoke hypoglycemia,” the doctor concluded.
Earlier, nutritionist Irina Stepnaya named a fruit ideal for weight loss. Eating pineapple every day can help you lose weight and improve bowel function, she said.
