If you do choose a low-carb diet providing less than 130 grams of carbs, only do so under medical supervision.

Therefore, you may notice weight loss from water, not body fat, after just a day or two of low-carb dieting.If youâre dieting safely on your own without medical supervision, youâll likely start to notice weight loss in about a week.iets containing 800 calories -- or less -- per day are classified as very low-calorie diets. Although you can lose weight rapidly using this type of diet, you should only do so under close supervision by a qualified health care provider.
The greater the absolute value of a correlation coefficient, the stronger the linear relationship. The strongest linear relationship is indicated by a correlation coefficient of -1 or 1. The weakest linear relationship is indicated by a correlation coefficient equal to 0. A positive correlation means that if one variable gets bigger, the other variable tends to get bigger.
Watch the movie below to get a feel for how the correlation relates to the strength of the linear association in a scatterplot. Below are some features about the correlation. The correlation of a sample is represented by the letter r. The range of possible values for a correlation is between -1 to +1. A positive correlation indicates a positive linear association like the one in example 5.8. The strength of the positive linear association increases as the correlation becomes closer to +1.
