Habits That Can Hurt Your Brain

How obesity can damage brain functions shows the relation between obesity and impaired brain functioning.

A 2020 study on brain imaging confirms that when a person’s weight goes up, all areas of the brain go down in activity and blood flow. Consequently, being overweight or obese has a profound effect on your brain activity and increases the risk of Alzheimer’s disease, and other mental issues.

However, any brain impairment linked to obesity can be reversed through weight loss and healthy lifestyle intervention.

And perhaps impacts the brain, according to researchers.


Finally, how obesity can damage brain functions brings up the issue of obesity and high risk of Alzheimer. According to a study, low cerebral blood flow is the no. 1 brain imaging predictor that a person will develop Alzheimer’s disease.

10 Ways To Manage And Prevent Obesity

One key lesson from studies is that brains can be improved when you place them in a healing setting that embraces brain-healthy habits. That is habits like weight loss, healthy diets, and healthy lifestyle interventions.  Find below 10 ways to manage and prevent obesity:

Stick to a healthy diet

If you’re trying to lose weight, do it slowly. This way, you’ll be able to keep the weight off and escape yoyo dieting that promotes obesity. Accordingly shun a severe weight loss programme that deprives your body of food altogether.

Yo-yo Dieting Promotes Obesity

The following tips help you eat healthy diet meals:

  • Eat a diet rich in lean protein, natural carbohydrates, whole grains, legumes, nuts, fruits, and vegetables.
  • Eat more greens such as broccoli, kale, spinach, and pumpkin leaves.
  • Eliminate candy, sugar, sodas, and all simple sugars from your diet. Excess sugar ends up being stored as fat in your body, which results in weight gain.
  • Keep dairies to a minimum because most are high in saturated fat.
  • Avoid fatty, processed or fried foods.

Drink more water

Water is the key to weight loss for it’s a natural appetite suppressant. When you drink more water, you’re flushing out toxins as well as teaching your body that it no longer needs to store water. The recommendation is to drink a minimum of 8 glasses of water a day.

Take extra fluid

People who eat a serving of soup daily lose more weight than those who eat the same amount of calories but do not eat soup. Hence, eating a bowl of light soup with vegetables and noodles at least once a day will help you lose pounds. Moreover, nutritious, low-salt soups will nourish you as they flush waste from your body.  

Avoid late dinner

Studies show that when you eat your daily protein and fat at breakfast you tend to lose weight and have more energy. However, eating the same things at dinner tends to increase weight gain. As a result, to keep off weight, aim to eat your dinner by 7 p.m.

Eat smaller meals

When you follow an eating schedule containing five little meals every day, you won’t be hungry and overeat at your next meal.  The trick is to keep low-fat nut mix and fruits around you to avoid the temptation of high-calorie snacks in between meals.

Get physically active
