Square, potatoes are not a worse carbohydrate than wheat or anything else; it also has potassium, which other carbs do not have. French fries are worse because of the saturated far from the oil. Whole wheat has more fiber, which helps in digestion, but potatoes themselves aren’t horrible.
Peanuts are very high in protein; they have fat too, but fat content alone doesn’t add weight (they used to think that 30 years ago). Peanuts butter, however can have sugar, which is not good.
Sugary sodas are just a public nuisance; zero nutrition and lots of bad stuff; sugar, acids..
Eating before bed is tricky; there are studies that show that people who eat before bed are more likely to gain weight – but these studies have a huge flaw. They don’t ask people if they’re eating their supper before bed – many are simply saying that they eat additional food before bed, and additional food means more calories. Science hasn’t discovered a direct cause and effect system that makes you gain weight from eating before sleeping, but it’s not disproven…just it’s not anywhere near proven that there’s a cause and effect.
