Please remember to consult with a healthcare provider prior to undertaking any of the protocols available here.

In this scenario, you have observed that you are:
(a) Eating a maintenance level of calories such that your weight is stable, \
(b) You **are** metabolically healthy. \
(c) Your clinician has assessed that **no** weight loss is required for medical purposes. \
(d) This also assumes that you have no diet-restricting medical conditions (e.g. kidney disease that would restrict volume of protein intake).
{% endhint %}
Maintain your existing daily caloric intake (while ensuring adequate protein intake).
* [You can approximate daily caloric requirements with simple calculators](https://www.mayoclinic.org/healthy-lifestyle/weight-loss/in-depth/calorie-calculator/itt-20402304), but this should always be referenced to body weight/body composition changes over time.
Second, consider adding the following general heuristics to your diet:
*Note:* *These heuristics may not apply for carbohydrate-restricted diets, and are taken from* [*the 2021 CCS guidelines*](https://onlinecjc.ca/article/S0828-282X\(21\)00165-3/fulltext#sec0028)*:*
1\. Aim for ≥30g nuts/day (can reduce `LDL-C` by 5-7%).
2\. Aim for extra-virgin olive oil as your oil of choice (≥60 mL/day).
3\. Aim for regular intake of fruits and vegetables (≥5 servings/day).
*P.S. - be careful with fruit or sugar-containing smoothies, since fruit juice and/or the process of blending away the fruit-fibre-matrix can deliver a sudden spike in blood glucose upon conumtpion.*
4\. Aim for regular intake of legumes (≥4 servings/week).
5\. Aim for >30 grams of fibre a day (whether through food or through fibre supplements like MetaMucil pills)
*Sub-recommendation: Consider a targeted aiming for fibre from specific sources: high viscous soluble fibre from oats, barley, psyllium, pectin, or konjac mannan (≥10 g/day) (e.g. MetaMucil powder/pills) (can reduce `LDL-C` by 5-10%).*
6\. Eating ≥ 3 servings of whole grains a day (assuming no carbohydrate-restricted diet).
[A simple 2-page guide that includes most of these heuristics is also available here. ](https://dhhs.ne.gov/Documents/Foods%20to%20Choose%20to%20Lower%20Your%20Cholesterol.pdf)
Third, pick an specific dietary protocol from one of the following options:
1\. [**Mediterranean diet.**](https://www.heartandstroke.ca/articles/an-all-canadian-healthy-diet)
* [This is the standard omnivorous diet recommended *for most* patients in the 2021 Canadian Cardiovascular Society Guidelines for dyslipidemia](https://onlinecjc.ca/article/S0828-282X\(21\)00165-3/fulltext#sec0028).
* This diet is easier for most people to adhere to relative to a carbohydrate-restricted diet or a plant-based diet since it includes animal foods.
* Note: [A low glycemic-index variation of the Mediterranean diet can also be implemented. ](https://www.mdpi.com/2072-6643/14/3/706)
2\. [**Plant-based vegan diet.**](https://www.heartandstroke.ca/articles/what-is-a-plant-based-diet)
* This is a viable alternative for individuals who do not wish to consume animal food products.
* This diet can[ lower `LDL` and `ApoB`.](https://academic.oup.com/eurheartj/article/44/28/2609/7177660)
* There is[ some limited evidence suggesting that, unique among dietary interventions, it may lower `Lp(a)`](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6489854/)).
* Pay special attention to micronutrient supplementation (e.g. Vitamin B12, creatine) if you are not consuming any animal products.
* Be mindful of your protein intake quality in particular - plant protein is less bioavailable than animal protein. [Click here for information on how to adjust your protein intake calculation for vegans. ](/foundational-protocols/dietary-optimization-meta-protocol/diet-selection-sub-protocol/protein-quality-for-vegans.md)
* Some individuals may wish to eat a primarily plant-based diet and include some limited elements of animal protein (e.g. dairy, fish, eggs), although some research suggests that healthy omnivorous diets[ may not be as effective as vegan diets in lowering LDL.](https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2812392) (on the positive side, they can provide easier access to higher protein quality and may be easier to adhere to).
3. **Low-glycemic index diet.**
* [This is a diet that is designed to avoid sudden spikes in blood glucose](https://www.health.harvard.edu/healthbeat/a-good-guide-to-good-carbs-the-glycemic-index), but unlike a ketogenic diet, it still allows for larger quantities of carbohydrates to be consumed, and may be easier to adhere to.
* [Note that low-glycemic foods can be selected *within* the parameters of a Mediterranean diet, and some researchers have found benefit from this combination of approaches.](https://medicalxpress.com/news/2022-06-health-benefits-mediterranean-diet-glycemic.html)
* If you are already eating this diet, you may continue doing so as you have already achieved metabolic optimization, however, we don't recommend *starting* this diet if you are already metabolically healthy and at a normal weight.
Fourth, implement the dietary protocol you picked in step 3, while incorporating the general heuristics from step two.
* We are currently working on an individualized meal-delivery service to assist our members in implementation.
