Obesity is a complex disease that has reached epidemic proportions in many parts of the globe. With the advent of technology, modern-day lifestyle and dietary habits, the cases of obesity have sky-rocketed over the turn of the century. Several factors can cause obesity, such as psychological factors like stress or anger, hormonal imbalance, pregnancy, socio-economic status, increasing urbanization, and hereditary predispositions. But diet is considered to be the most vital aspect of our life that leads to obesity. But there are many diet fads out there that do more damage than good. So, we’ll focus on a diet for obesity that actually works! Therefore, we will talk about the 11 best dietary modifications for obesity.

Best diet for obesity

A simple modification in your diet can go a long way in the successful dietary management of obesity. Before we head to the modifications, let’s look at why diet is so important in obesity management and even more important than exercise.

Dietary Modifications For Obesity – Why Diet is More Important Than Exercise For Weight Loss

The first thing that comes to mind when talking about weight loss is exercise. Most people tend to equate weight loss with exercise. While exercise does play a key role in combating obesity, it is the diet that takes the cakes as the most crucial weapon in a weight loss plan. It is the most critical part of all the lifestyle changes to lose weight. But why is diet so vital? And how is it even more important than exercise?

Diet for weight loss

The importance of eating patterns for weight loss cannot be stressed enough. In fact, diet is more important than exercise when it comes to losing those pounds. Several studies, too, have backed this claim. Even if you consistently exercise, it won’t show any results if you follow an unhealthy diet. One bad meal can sabotage your entire fitness plan. Piling on the calories through unhealthy food can be surprisingly effortless. So, keeping an eye on your plate is more vital than the miles you run.

By the simple act of omitting certain foods that are high in fats, sugar, refined carbs and calories, you can arrest weight gain. There is another unintended result of exercise; a workout session could stir up your appetite, thus tempting you to gorge on a heavy meal. Burning calories is a more demanding and challenging task than not piling up calories through a proper diet. All things considered; exercise is essential but just not as important as diet in your weight-loss journey.

Read on to find out the best dietary modifications that can help tackle obesity.
