Most of the advice for people in the early stages of HD is the usual, generic advice for good nutrition. Later, losing weight is a thing. So is swallowing. “There is also some evidence that maintaining a body weight slightly above ‘desirable’ weight will facilitate control of the disease.”
There’s no verified causal link between particular foods/groups and HD symptoms (for better or worse). But there are recommendations, sometimes for specific supplements, like calcium.
I’ve experimented enough with dieting content and timing (fasting, keto, low carb, FODMAP, diabetic restrictions) to know what my body is comfortable with.

My goals:

• stable diet, so that I can monitor changes in supplements as I experiment
• log diet info, so that I can supplement nutrients as needed
• shop with a super low budget
• eat mostly whole, single ingredient foods
• eat mostly foods that don’t bother me for any reason

Macros and Supplements

I was craving carbs, hungry all the time. I’ve tried everything I could find online to mitigate this, promise. I feel ok with keto, and even better fasting, for a day or so. But it’s not something I could maintain long-term. For me, the trick was counting carbs so that the total is about 150, but only about 50 at any one time. I’m notoriously bad at sticking to a recipe (ok, following instructions in general), but I’ve started measuring food. And I’m good with averaging: I eat 2300 kc one day and 1500 the next. I don’t pay much attention to the other macros.
I was getting most of the official RDA for everything but vitamins D and E, so I added them to the daily mix. I also like to tweak the recommendations to include the AREDS2 list. Following that, I was also low on a couple of minerals. I have a few bottles of multivitamins, so I’ve been taking 1/3 of one every day, to add some extra minerals and Bs.
My serum Mg was low. I poop normally when I am taking the Mg supplement. So I take it. And it’s recommended to take Calcium if you’re supplementing Mg, so I take that, too.
The glucosamine is a definite plus, I’m still experimenting with the collagen.

Foods

I’m losing weight (very slowly) but at this stage in my HD progress, that’s fine. I need to lose a little for my knees and hips. Here’s what I ate one day:

1. coffee + cream, 3 eggs and some spinach sauteed in olive oil
2. a half cup of lentils and a half cup of collards (some olive oil in both)
3. a sweet potato and a boiled egg
4. a cup of lentils and a boiled egg
5. .8 cup of rice and a boiled egg and half a cup of collards

Plus some water, tea, and diet drinks. I didn’t feel hungry, it was about 2,000 kc. I cooked the lentils and rice from dry; sweet potato, collards, and spinach from fresh. Most days I don’t eat so many eggs and have some tuna with yellow mustard and sugar free sweet pickle relish. I usually have some frozen berries (cherries or blueberries). And popcorn in olive oil. I use salt and fresh pepper in everything, ginger in green tea.
I prefer fresh, will make do with frozen. I’ll sub any greens for collards, chick peas for lentils. On the road I’ll get canned veggies, fresh fruit, and precooked eggs.
I try to eat to reduce inflammation. I add hot spices (ginger, peppers), especially to inflammatory foods like meat. I eat yellow mustard for turmeric, pickles and an occasional beer for gut health. (I hate yogurt, sorry, mom.)

What I Do Eat (90%): It’s easier to concentrate on what to eat, since it’s a shorter list and it makes shopping and decisions quick.

• Rice and corn without anything added and stuff made from it (tortillas, rice cakes, popcorn)
• Green and yellow vegetables (greens, salad greens, cucumbers, asparagus, cactus, artichokes, squash, yam/sweet potato, carrot, pumpkin), avocado, olives, pickles
• Berries (all of them) and cherries
• Eggs, fish, and occasionally chicken
• Coffee, tea, water, fizzy no sugar drinks (prefer stevia, then splenda)
• Rarely: sunflower seeds, walnuts

What I Don’t Eat Much Of (10%): the anti-list (why it’s off limits for me):

• Restaurant food (too many surprises)
• Sauces and anything in a packet (ditto)
• Sugars – honey, agave, corn syrup, all of it (inflammation and blood sugar regulation)
• Fruit that is not berries, large quantities of tomatoes, and any fruit juice (ditto)
• Garlic/onion (GI issues)
• Beans other than chick peas or lentils (ditto)
• Regular dairy products (ditto)
• Grains other than corn and rice (inflammation)
• Red meat (expensive, sustainability issues, often has surprise additives like sugar in jerky)
• Nuts (expensive)
• Pretty much anything not on the other list

Budgeting $55-$65/Week + The 10%

• $15/week for the veggies, beans, and rice
• $7 for eggs/tuna
• $7-12 for frozen fruit
• $15 for carbonated flavored water or sugar free sodas*.
• In hot weather I try to drink an electrolyte powder every day, another $3.
• Every month or so it’s another $10-15 for yellow mustard, olive oil, spices, green tea, coffee, etc.

Tools

I log all the supplements, food, drink and exercise. I don’t check it much, now that I got the carb and nutrient targets where I wanted.

I set it up by adding the food I ate everyday (it does a lookup on a partial text). I added all the supplements. Now I just copy the previous day and edit individual values.
It auto-calculates the nutrients for everything. You can choose which are highlighted, and you can set the range of acceptable values.

Making It Interesting vs Making It Work

I love food and eating. I’m a creature of habit but also sometimes bored. So I’ve tried things like making jello from plain gelatin and electrolyte powder and adding frozen blueberries at the end. I take peach fizzy water and mix it with stevia and matcha and sprinkle ginger on top. It helps that I love the taste of olive oil + salt + pepper + any vegetable. That I love eggs. And olives. That I tolerate fish pretty well with olive oil and heat or cool and pickles, sweet or not. That I love salad and avocado and olive oil. I like to saute jalapenos and then add the eggs or veggies. That I use curry powder and cumin in the lentils. And/or the greens. I use chai spices on the squash and yams. And did I mention olive oil?
So this works for me because I already like the food on the list. I imagine it would be harder to transition if I didn’t like veggies so much.

And when I stick close to it, I feel noticeably less fatigued during the day. So this is what works for me, for now.
