Short Summary
Main recommendation: On a low-carb or keto diet, avoid high-carb foods such as sugary foods and drinks, sauces and condiments, low-fat salad dressings, natural sugars, fruit (except small amounts of lower-carb fruit), grains and cereals (including whole grain versions), starchy vegetables, cashew nuts, milk-heavy drinks, and beer. Dr. Eric Westman, reacting to Dr. Dan Mags's video, frames this as a set of foods to limit rather than a strict ban on everything, since the amount matters, based on his own clinical teaching approach.
Key Points
- Sugary foods and drinks raise blood glucose, which triggers insulin release; Dr. Westman says insulin is the fat-storage and fat-creating hormone, in his view.
- Hidden sugar hides in sauces like ketchup, barbecue, teriyaki, and hoisin, and in low-fat salad dressings, which Dr. Dan Mags and Dr. Westman say often add sugar for flavor.
- Whole grain, rye, and sourdough breads are still high in starch that breaks down into glucose, so they are not treated as low-carb alternatives.
- Starchy vegetables (potatoes, sweet potatoes, parsnips, cassava/yuca) and cashews are flagged as high-carb, with cashews cited by Dr. Dan Mags as having three to five times the carbs of most other nuts.
- Dr. Westman notes that, in his clinical experience, moderation rather than total avoidance is possible for some foods over time, and that a daily alcohol drink can often be tolerated while still getting good results, though he does not guarantee it will work for everyone.
Details Worth Noting
- Concrete instructions:
- Eat real, unprocessed food and check labels for hidden sugars.
- Read total carbs on nutrition labels; for prescription-strength keto, use total carbs rather than net carbs. For over-the-counter keto, net carbs (total carbs minus fiber and sugar alcohols) may be used.
- Choose blue cheese, ranch, Caesar, or oil-and-vinegar dressings, which the speaker lists as lowest in carbs; blue cheese is least likely to have added sugar at restaurants.
- Dr. Westman suggests replacing bread with a chaffle (a cheese and egg waffle made in a waffle iron at home), as his personal recommendation.
- If choosing fruit, Dr. Westman says grapefruit is probably the lowest-carb option, but notes you should check with a doctor if you take medications, since grapefruit juice can interfere with absorption.
- Limit milk to a small splash in a few coffees per day rather than lattes or cappuccinos.
- If drinking alcohol, choose a hard liquor shot with a sugar-free mixer, a 12-ounce low-carb beer, or a glass of wine, which the speaker estimates at about five carbs each, and keep it to about one drink a day.
- Eat unlimited meat, poultry, fish, and eggs until comfortably full.
- The speaker states a teaspoon of sugar is about five grams of carbohydrate, and that the bloodstream holds about one teaspoon of sugar at a time.
- Example figures from the video: a banana has about six teaspoons of sugar equivalent, watermelon under two, a slice of white bread about 3.7, and 200 ml of apple juice roughly the same as a can of soda.
- The speaker says nuts are hard to control and suggests avoiding them at first on prescription-strength keto, with macadamia nuts as the lowest-carb option.
Bottom Line
Low-carb eating is less about banning foods and more about recognizing hidden carbs in products marketed as healthy and controlling portions of the higher-carb items, according to the speaker's clinical experience.
