Diabetes mellitus (DM) and non-alcoholic fatty liver disease (NAFLD) are inseparably entwined, each worsening the condition of the other. Different types of drugs are being described to counter the disease. Nutritional challenges are far more in combined illness. We wanted to focus on the intricate difficulties of managing such a comorbid case about diet and nutrition. A detailed search of the articles from Pubmed, Cochrane and Scopus databases were made to consolidate the findings in a concise way to be presentable highlighting the nucleus of the problem. A nominal 10 __ampersandsignndash; 15 % decrease in the calories will be beneficial in both illnesses. Strict avoidance of excess alcohol and soft drinks is a must. Diet with added fructose should be avoided. Still, garlic with oligofructose is beneficial. Use of vegetable oils rich in polyunsaturated fatty acids will help in decreasing the incidence of fatty liver. The intake of unprocessed food like whole grains, nuts, legumes, fruits and seeds with high fibre content and fewer simple sugars are recommended. Spaced slow intake of restricted calorie diet is ideal. Five planned menus for a 600-calorie diet are given. The diet can be adjusted to 1500 __ampersandsignndash; 2000 calories according to the need of the patient. The confounding factors which modify these plans are age, sex, Body mass index and the regular physical activities of each individual. A mildly modified but eatable menu in the diet can be achieved to counter the comorbid conditions of diabetes mellitus and NAFLD. A very low calorie (600 calories/day) diet may be beneficial to NAFLD but needs caution in the incidence of abnormal glycaemic swings. A 10 % reduction in weight is useful in NAFLD.
