LP = Low Protein. HP = High Protein. LGI = Low GI. HGI = High GI. |
"In conclusion, in this large, randomized study, a diet that was
moderately high in protein content and slightly reduced in glycemic
index improved the rate of completion of the intervention and
maintenance of weight loss and therefore appears to be ideal for the
prevention of weight regain."
Note that Low GI isn't the same as Low carb. The Low GI diets had ~43% of total energy from carbohydrate.
The Low GI diets were not Low carb diets. They weren't as High carb as Healthy Eating Guidelines (55% of total energy from carbohydrate).
