Question 1

Will I gain weight from all the carbs?

Accepted Answer

Very likely, especially once the initial water weight returns. The RS2 diet improved meal glucose handling without improving insulin sensitivity. However, there was no improvement in HbA1c after 12 weeks in well-controlled individuals with type 2 diabetes mellitus7. The massive insulin responses to high-starch meals promote fat storage, particularly around your midsection.

Question 2

Can I get enough protein?

Accepted Answer

It's challenging on a high-starch vegan diet. Plant proteins often lack essential amino acids and come packaged with antinutrients that reduce absorption. The quality and quantity may prove insufficient to prevent muscle loss, especially as you age.

Question 3

Are potatoes unhealthy?

Accepted Answer

In moderation, potatoes provide nutrients. But eaten in large quantities as the dietary foundation, their impact on blood sugar becomes problematic. Starchy foods are rich in glucose precursors such as amylopectin, which is the main form of rapidly digestible starch in the human body2. A diet centered on high-glycemic starches sets you up for metabolic dysfunction.
