Deciding what diet to choose is sometimes as hard as dieting itself. The latest diet craze is called “flexible dieting.”

Dr. Tonya Hunt, a registered dietitian at St. Barnabas Hospital, says macros dieting, or flexible dieting, has been around for years. The body-building community has made use of it for years, but it is now becoming mainstream.

Macros is based on a 2,000-calorie diet, with the breakdown of 40, 40 and 20 used most commonly. This breakdown involves 200 grams of carbohydrates, 200 grams of protein and 40 grams of fat.

A lot of planning is involved with this diet. Dr. Hunt suggests using a food scale to measure the amount of proteins, carbohydrates and fats in your diet. She also suggests keeping a food journal, writing down the amount of proteins, carbohydrates and fats that are in your diet.

An example of a healthy snack on the macros diet is Greek yogurt because it doesn't have a lot of sugars, according to Dr. Hunt. To boost the nutritional value, Dr. Hunt suggests adding flaxseed, which helps lower cholesterol because of its fiber and omega-3 fatty acids.

Dr. Hunt says although a good amount of planning is involved with the macros diet, it is beneficial in the long run.
