Avoiding gluten, dairy, or sugar really requires getting proficient at preparing all your meals from scratch. It’s a good skillset to develop, but there’s major hurdles. What are the chances that every single day you’re going to have the time and energy to cook 2 meals from raw ingredients instead of grabbing a box/freezer meal or takeout? It’s not a pure question of whether someone has the willpower to say no to a craving, they have to have the discipline to plan and prepare meals before they are hungry.
Absolute adherence to dietary restrictions is very difficult even when addiction isn’t a major component.
Fructose in particular causes liver damage at a much higher rate than other carbohydrates including glucose. It’s not as simple as excess calories.
There are more non-obese diabetics than obese diabetics. Yes, there’s a strong correlation between weight and diabetes, but that has more to do with metabolic disorders causing both weight gain and insulin resistance.

Title says Quercus, but emojis say Castanea.
Does anyone know what that grabber device is? I like to use grabbers to pick up chestnuts, but the ones I have are pretty flimsy. This thing looks like a beast in comparison.
Did they take that toothbrush to a belt sander?

Hold an in class quiz with essentially the same problem but with different values. The students that actually worked through the problem should be able to do it again with the changes. Those who didn’t understand and just put down what their peers got will struggle with a quiz. Bonus points if you can restructure the problem in a way to elucidate which specific aspects you think the students were skipping over with help from their peers. Feel free to have specific requirements assigned point values in the problem statement.
Don’t call them into your office and put them on the spot. That will make this adversarial. Your job is to teach them how to solve problems and communicate their methods in a clear fashion. You should reevaluate your problem writing and grading policies if just looking up answers can earn a passing grade. If you give a quiz, be up front with them that you have concerns about some students skipping the work and copying answers. Reiterate that the point of the exam was to make sure they can solve problems, the correct answer is merely a byproduct.
I will add speculation that there is a difference between what your students think you expect from an answer and what your expectations actually are. Mismatches in expectations are immensely frustrating for both parties. So don’t leave your students guessing. Give them specific examples of work of different quality and what aspects earn full points and what things might lead to point deductions. Some of the best professors I had would publish all the prior year exams with their solutions. That gave everyone the opportunity to mimic the workflow and match the level of detail expected. That also elliminates the concern of students finding the answers online or from prior year students for exams as the teacher will have had to avoid reused questions entirely.
