The Science Behind Weight Loss Programs

While millions of Americans can tell you about weight loss programs or cult diets like the South Beach Diet or the Atkins Diet, most of them can’t assure you whether such diets are scientifically healthy. The confusion across the science behind dieting and weight loss has stoked controversy both among health and fitness experts, and lay individuals who would like to lose weight.

Look no further than the controversy over the low-carb, high-fat Atkins Diet. Proponents of the High-protein, high-fat diet argued that excessive amounts of fat are really good for weight loss, arguing that “One can lose weight on a low-calorie diet if it is principally composed of fat calories or carbohydrate calories or protein calories”.

Not so, argued other health experts. The Journal of the American Dietetic Association(JADA) ran a series of health analyses and encountered that the scientific information disagreed with the high-fat argument (source).

No wonder that millions of people are confused about the science behind weight loss plans. On the one hand, you’ve medical investigators arguing one thing. On the other hand, you’ve weight loss promoters arguing the exact contrary. In this health and fitness report, I’ll discuss the basic principle of protein, carbohydrates, and fat, also as how these three diet elements play a role in healthy, sustained dieting and weight loss. It’s vital that dieters understand the science behind their weight loss programs for them to make informed, healthy choices on losing weight.

The Scientific Health Basics of Fat, Carbs, and Protein in a Diet:

A few of your friends might be telling you that the best path to losing those undesired fats is by going to the gym. Do you believe this is the best solution? What is true is working out would help you tone those muscles up. You might be wondering why some that goes to the gym for a long time already but still they continue complaining about their figure.

Many people not going to the gym but is on a diet and have an active lifestyle can see better results than those who are going to the gym. Did I mention the word diet and active lifestyle? Yes! This two are the top most priority for a person that prefer to* have that body figure of their dreams.

Lets us now reply the question, what makes a person fatty. Diet is not a weight loss but by dieting, you’ll be able to keep a low-calorie diet. Do you know that our body needs proteins, carbohydrates, and fats? Do you also know that the three I mentioned, we can get calories in them? You could want to know how many calories each can give you so here let me discuss a little of each.


This is one of the most crucial of all diet programs. 1 gram of this equals to calories. So if you’ll eat at least 40 grams of protein you multiply it by four, you’ll get at least 160 calories. It’s a very simple maths it’s like 40 grams protein x 4 = 160 calories. The good thing about proteins our body needs several this, so you don’t need to care if consume many proteins, have you heard of a protein supplement? This is use by a person who are going to the gym or persons that have a very active lifestyle.

Carbohydrates (carbs):

Like the protein, 1 gram of carbs is equaled to 4 calories so if you’re consuming 20 grams of carbs multiply by four that would be 80 calories. Virtually all food has carbs in it so it would be impossible to get away from carbs.


Contrary to the two, protein and carbohydrates; one gram of fats is equaled to 9 calories. So if you eat thirty grams of fats, you’ll get two hundred and seventy calories. That is 30 carbs x 9 = 270 calories. Now you know why most people who are sensible about their figure and health would deprive themselves of eating several fatty foods.

Diet doesn’t mean you need to skip meals, but it means don’t go over the limits. To that very active person, they can consume more because they burn more calories but they would choose not too if they are that conscious. But to those who don’t have an active lifestyle they should choose to consume fewer calories. The answer would depend on upon the person; it would depend on upon you. Just make the right selection and begin today!
