On the assumption that there are 16 tablespoons in 1 cup (liquid measure), that would make 5.96 gm of carbohydrates in 1 T. On the better assumption that there are 12 tablespoons in 1 cup (dry measure), that makes 7.9 gm/T.

Since its inception in the 1970s as the "Drinking Man’s Diet", the carbohydrate-limited diet has been notorious as a VERY BAD approach to planning ones’ eating habits because:

- the most important part of a healthy diet is complex carbohydrates

- risk of malnutrition because important nutritional elements are removed from the diet (e.g. ‘fibre’ is essential in avoiding constipation, in the short term, and colorectal cancer in the long term. Do you know the phrase "colostomy bag"?)

- because it works by ****ing up your metabolism, any weight lost returns almost immediately when a ‘normal’ diet is resumed

- temporary weight loss/gain leads to permanent wrinkles and stretch marks.

- permanent kidney damage/ketosis (symptom: your breath smells like nail polish remover). Do you like the idea of being slim - - and on a dialysis machine, or trying to find a donor kidney?

PLEASE, there are many more healthful ways of keeping oneself slim. There are NO QUICK TRICKS ‘DIETS’ that work more effectively than eating moderate quantities of a variety of foods, and regular physical activity.
