The answer depends on how we choose to eat it.
Potatoes are a nutritious, calorie-dilute, complex carbohydrate - and only 1% of its calories come from fat.
UNTIL....
… we fry that potato in grease to make French fries (46% fat), or convert that potato into potato chips (56% fat).
Or until we smother that potato with butter, sour cream, cheese sauce, and bacon bits - which adds a huge dose of fat (and cholesterol).
As you can see, the potato at 1% fat isn't adding to our weight struggles. It's when we convert that complex carb potato into a REFINED junk food carb that our troubles begin.
As Dr. McDougall likes to remind us: Carbs don't make us fat - FAT makes us fat.
Fortunately, we can make delicious Fat-Free Fit Fries, or Roasted Sweet Potato Wedges, and top our potatoes with delicious Golden Gravy, Mushroom Gravy (omit the oil), Cheese sauce, Mexican Cheese Sauce, Pimento Cream Sauce, your favorite salsa, or your favorite soup!
(Other topping ideas are listed in the "Foods for the Plan" chapter of the book, The "Plan A" Diet. Do you have a favorite, whole food, plant-based, no-added-oil potato topper?)
He gave plenty to drink to those who were thirsty. He filled those who were hungry with good food. (Psalm 107:9, GW)
