Is-Healthy-Foods-For-Weight Loss Still Relevant

Table of Contents

Losing weight can be a daunting task and we often have to put in some hard work to achieve this feat. Statistics show that it is important for us to keep a 80-20 balance, which means that 80% of the focus should be on nutrition and 20% on exercise and other physical activities for weight loss to be effective. While there is a lot of information and misinformation, we have assessed over 20 research papers related to weight loss and have simplified how food impacts weight management and which food products to eat for a sustainable weight loss.

Understanding Calories and Weight Loss

Understanding-Calories-and-Weight-Loss

When we talk about weight loss, we talk about calories. In reality calories are essential for us in our daily living. It is the basic energy fuel used by our body to function effectively. When we eat food, we consume calories and when we engage in physical activity or sleep we burn calories. Even our body itself keeps burning calories for its internal functions like digestion, healing etc.  When examining weight loss the quantity of food consumption matters less than the quality and the type of food we put into our system.

The difference between calories we intake and calories we burn determines our weight gain or weight loss. In simple terms

If, Calories intake >  Calories burnt =  Increase in body weight

Or,

If, Calories intake <  Calories burnt =  Decrease in body weight

Typically to lose 1 gram of body fat you need to burn 700 calories more than what you intake. What is important to understand here is that you need a calorie deficit to lose weight.

But are all calories the same? Would consuming 1 calorie of carbohydrates as compared to 1 calorie of proteins or fat get the same nutrition  and would reducing their intake lead to similar weight control?

Actually, No. However, there are a lot of misconceptions around this. A calorie from sugar might only give you carbs, but a calorie from Spinach, would give you other essential nutrients as well. 

Latest research suggests that some foods may make it easier to keep calories in check like grains, fruits and nuts, while others foods like refined carbs and sugar may make people more likely to overeat. We will examine the details of this further in the article.

Then there are other misconceptions about different foods. Many of us believe completely cutting out fat from their diet will help them in losing weight but research states otherwise. In fact studies show that the consumption of fat has reduced significantly but the obesity rate is still high.

Healthy food therefore consists of those food items that are rich in nutrients and proteins. These food products also keep us filled for longer. It provides the body with energy and increases overall health.

Food categories and their impact on weight loss? So, how healthy food is still relevant for weight loss?

Food-categories-and-their-impact-on-Weight-loss

  • Do fats lead to weight gain?

A common misconception among people is that Fats are a strict No-No, when it comes to weight loss. A research study conducted in the US showed that foods low in fat contain high carbohydrate contents and don’t really help in losing weight. Instead, people who consumed a moderate to high fat diet lost just as much weight and in some studies even more weight than people who consumed a low fat diet. The problem here being that foods that are low in fat are high in carbs which makes you susceptible to weight gain, obesity and cardiovascular diseases.

Infact, the type of fat that we consume impacts our weight more. Another eight year study on females showed that increasing mono-saturated and polyunsaturated fat in diet did not impact weight change, however increasing trans fat, saturated fat and animal fat had a positive correlation with weight change.

  • Can Protein impact body weight?

Most certainly Yes.  As per research, a high protein diet certainly has a positive impact on weight reduction at least in the short term.  The reduction in weight can also be  attributed to higher fat and lower  carbohydrates associated with high protein diet. Two key factors of protein making you feel fuller, and higher energy requirements to digest proteins contribute to weight loss by reducing the food intake. 

Similar to fats, The type of protein is equally important.  While as per study spanning over 20 years people Consuming red meat and processed meat  had witnessed  a higher weight gain  in comparison to  people consuming nuts, beans, fish, or poultry.  In addition red meat and processed meat have also been linked to enhance the risk of heart disease, diabetes, and colon cancer whereas nuts, beans, fish, or poultry seems to lower the risk of heart disease and diabetes.

  • Are all carbs the same for weight loss? 

                                                         Are all carbs the same for weight loss

Reduction of carbohydrate intake certainly contributes to weight loss over a short period of time. However, for a sustained weight management, less processed forms of carbohydrates like whole wheat, brown rice, barley, and other whole grains-are digested more slowly than refined grains. Refined grains  when consumed  get easily digested in the body. These are called foods with high glycemic index which cause immediate increase in blood sugar and insulin leading to short spikes of hunger. People often tend to overeat because of this, if this continues over a long term  it can certainly lead to weight gain and diabetes. High fiber content in whole grains increases the time taken for digestion and keeps us full on lower calories.

  • Sugar – sweetened beverages and weight

                                                            Sugar-Sweetened Beverages and Weight

Refined sugars are high in carbs and when we consume more of it in liquid form for example through our energy drinks or fruit juices or Sodas it increases hunger thus causing us to eat more. A meta-analysis of 88 studies found clear associations of soft drink intake with increased energy intake and body weight. Also, foods that are high in refined sugar increases the risk of obesity and cardiovascular diseases. 

  •  Fruit juice

Fruit juice

Against the popular notion of people eating fruit juices are not a  healthier option for weight loss than sugar-sweetened beverages.   Even fruit juices with 100% fruit and no added sugar fruit juices are as high in sugar and calories as sugary sodas. This is established by a 20 years long study on diet and lifestyle habits of 120,000 men and women. Research found that people who increased their intake of fruit juice gained more weight over time than people who did not.

  • Alcohol

Alcohol

There are limited or no studies to establish  that moderate drinking leads to weight gain. However, as per few recent studies on diet and Lifestyle change found that increasing alcohol  intake did lead to   increasing weight. The results also vary with the type of alcohol consumed the findings varied by type of alcohol.

  • Processed food

Highly processed foods linked to accelerated biological aging

According to results from a National Institutes of Health study, people who consumed more processed food had a significant increase in their calories. Differences seen even when both groups are given the same calorie amounts. unprocessed food items contain natural edible food parts from plants and animals. 

So what exactly are some foods that help in weight loss and how do we eat right?
