Terminologies related to Obesity diet
In this diet conscious era, every day we come across many health tips and health related posts on social media. In everyday life we are so familiar with the diet related terminologies that we use them routinely a in our day to day life. But they have some minor to gross differences. Let us be familiar today with some of the terminologies related with obesity.
.Low calorie diet – Low calorie diets help by decreasing energy intake (calories) which helps the body to burn off fat. A low calorie diet is regarded as a one which has a daily calorie intake of between 1,000 and 1,500 calories for a woman and between 1,500 and 2,000 for a man.
Very low calorie diet – A very low calorie diet (VLCD) is where the daily calorie intake is less than 1,000 calories.It is advised that this diet should only be followed by people who are considered to be very overweight, and that the diet should not be followed for more than 12 weeks.A VLCD is quite an extreme diet to follow so it is particularly important to seek the advice of a dietitian.
Low fat diet – A low fat diet involves reducing the amount of saturated fat and cholesterol in the diet. Reducing the fat content of diet can help to cut down on calories and promote healthier food choices at the same time.Many foods that have a high fat content also have high carbohydrate contents, such as hamburgers, pizzas, curries and pastries, so a low fat diet also has the potential to reduce blood sugar levels as well.
We should be aware of some low fat products as a number of low fat products simply replace the fats with a higher carb content.Fat provides nine calories per gram while carbohydrates and protein each provide four calories per gram, so choosing low-fat foods makes it possible to eat a larger volume of food for the same number of calories. It is recommended that limiting fat intake to 35% of total calories to help prevent obesity and to help control saturated fat intake.Comparing food labels of different products can help to pick the right choices.
Very Low fat diet– Avery low fat diet is defined as one in which ≤15% of total calories are derived from fat (33 g for a 2000-calorie diet, 50 g for a 3000-calorie diet) with fat calories distributed approximately equally among saturated, monounsaturated, and polyunsaturated fatty acids.
Low carb diet – The American Academy of family physicians define low-carbohydrate diets as diets that restrict carbohydrate intake to 20 to 60 grams per day, typically less than 20% of caloric intake. A 2016 reviewof low-carbohydrate diets classified diets with 50g of carbohydrate per day (less than 10% of total calories) as “very low” and diets with 40% of calories from carbohydrates as “mild” low-carbohydrate diets.
Ketogenic diet–.A ketogenic diet is a very low-carb diet, considered to be when we eat a level of carbohydrate of around 30g per day or below. This encourages the body to get its energy from burning body fat which produces an energy source known as ketones.
On a ketogenic diet, blood glucose levels are kept at a low but healthy level which encourages the body to break down fat into a fuel source known as ketones.
The process of breaking down or ‘burning’ body fat is known as ketosis.
Ketogenic diets are very effective at achieving two common aims of diabetes control, lowering blood glucose levels and reducing weight.The diet helps to lower the body’s demand for insulin which has benefits for people with type 1 and type 2 diabetes.
This type of diet should be followed strictly under the control of a physician and dietitian.
