In the USA, millions of people are overweight or obese, including both adults and children.
Obesity, or too much fat in the body, is a big risk factors for many chronic diseases.
The more body fat a person has and the more they weigh, the more likely they are to develop diseases such as diabetes, heart disease, stroke, arthritis, breathing problems, and some cancers.
Being overweight or obese can also change a person’s body image and self-confidence, harming one’s mental health.
That is why weight loss is very important if you have obesity. Losing body weight is linked to lower risk of many diseases, recent studies find.
Many factors can influence your weight loss. This includes your living environment, family history and genetics, your metabolic functions, your lifestyle and more.
Accordingly, there are many ways to lose body weight. You can use low-calorie diets, take intensive workouts, consuming weight loss supplements, using meal replacements, or undergo weight loss surgery.
Researchers have found that not all weight loss methods are equal when it comes to the risk of cardiovascular diseases.
In a recent study from University of South Australia, scientists compared the effects of different weight loss methods on cardiovascular diseases.
The team find that deliberate weight loss could reduce total mortality by 16% in obese people with high risk of type 2 diabetes.
If they chose dietary weight loss methods, they could reduce their cardiovascular risk by 21% when losing 10% of body weight.
If they chose bariatric surgery, they could reduce their cardiovascular risk by 32% while losing more body weight.
The study also shows that when obese people replaced carb with protein in their diets, they could maintain weight loss over 12 months and their blood pressure and cholesterol levels were better.
If obese people chose a very-low-carb diet, their LDL cholesterol levels increased when a high saturated fat ‘Atkins’ style method was used, while a high unsaturated fat version of such as diet is safe and effective.
In fact, a very-low-card diet rich in unsaturated fat can help obese people with type 2 diabetes maintain a healthy body weight and reduce drug use.
The researchers also find that a very-low-calorie liquid diet could strongly reduce body weight in the short-term, but long-term weight loss is no different to less restrictive dieting.
Finally, a high-protein, low-carb diet may be superior for weight loss management and reducing cardiovascular risk, but this requires future research.
