Low-Carb Diet
A broad approach that reduces carbohydrate without necessarily aiming for ketosis.
What Is It?
Low-carb eating reduces foods rich in carbohydrate while emphasizing protein, non-starchy vegetables, and fats. Unlike ketogenic diets, there is no single cutoff and no requirement to produce ketones, which makes the approach easier to personalize.
How It Works
Refined grains, sugary drinks, sweets, and large starch portions are reduced first. Depending on the version, beans, whole grains, fruit, and starchy vegetables may still fit. Food quality and total energy intake remain important even when carbohydrate is lower.
Potential upsides
- Can reduce refined carbohydrate intake
- Often improves short-term satiety
- Flexible carbohydrate target
- May support short-term weight loss
- Can include abundant non-starchy vegetables
+ Common foods
- •Eggs, fish, poultry, tofu, and lean meat
- •Leafy and non-starchy vegetables
- •Nuts, seeds, avocado, and olive oil
- •Unsweetened dairy
- •Measured portions of beans, fruit, or whole grains
− Typically limited or excluded

- •Large portions of pasta, rice, and potatoes
- •Highly processed low-carb products

EVIDENCE What the research says
Randomized trials show that lower-carbohydrate and lower-fat patterns can both support weight loss. Average long-term differences are often modest, so adherence, food quality, medications, and individual metabolic response matter more than the label alone.
