How many carbs should I eat on a low carb diet?

A low carb diet typically includes 50-130 grams of carbohydrates per day (compared to 200-300g on a standard diet). For weight loss, aim for 50-100g of carbs per day. This is enough to include vegetables, fruits, and small amounts of whole grains while still reducing insulin levels and promoting fat burning. Keto is more extreme at under 50g per day.

Can I lose weight on a low carb diet?

Yes. Low carb diets produce 2-3 times more weight loss than low-fat diets in the first 6 months, according to multiple studies. They work by reducing insulin (the fat-storage hormone), increasing fat burning, and naturally reducing calorie intake through higher protein and fat. Long-term results are similar to other diets when calories are matched.

What foods can I eat on a low carb diet?

Low carb foods include: meat, fish, eggs, cheese, Greek yogurt, non-starchy vegetables (broccoli, spinach, cauliflower, peppers), nuts and seeds, healthy oils (olive, coconut, avocado), berries, and small amounts of whole grains. Avoid: bread, pasta, rice, potatoes, sugar, soda, fruit juice, and processed foods.

Is low carb or keto better for weight loss?

Both produce similar weight loss over 12 months. Keto (under 50g carbs) produces faster initial weight loss but is harder to sustain. Low carb (50-130g) is more flexible, allows more food variety, and is easier to maintain long-term. For most people, low carb is the better starting point. Read our keto guide for the more extreme option.

Can I combine a low carb diet with GLP-1 medications?

Yes. GLP-1 medications reduce appetite and improve insulin sensitivity, which complements the low carb approach perfectly. Both target insulin resistance — the root cause of weight gain for many people. This combination can produce 15-22% weight loss in clinical trials. If your BMI is 30 or higher, check your eligibility.

What is a low carb diet?

A low carb diet reduces carbohydrate intake to 50-130 grams per day (compared to 200-300g on a standard American diet). This is not as extreme as keto (under 50g) but still significantly reduces carbs from bread, pasta, rice, and sugar. The result: lower insulin, increased fat burning, and reduced appetite.

Multiple studies show low carb diets produce 2-3 times more weight loss than low-fat diets in the first 6 months. They are particularly effective for people with insulin resistance, prediabetes, or type 2 diabetes.

How many carbs should you eat?

Moderate low carb (100-130g): Best for maintenance and active people
Standard low carb (50-100g): Best for weight loss — allows vegetables, berries, small amounts of grains
Very low carb / keto (under 50g): Fastest results but most restrictive — read our Keto Guide

Most people lose weight effectively at 50-100g of carbs per day. This allows plenty of vegetables, some fruit, and occasional whole grains while still promoting fat burning.

Why low carb works for weight loss

Lower insulin: Carbs raise insulin, the fat-storage hormone. Fewer carbs = less fat storage
Increased fat burning: Lower insulin allows your body to access stored fat for energy
Reduced appetite: Protein and fat are more satiating than carbs — you naturally eat less
Water weight loss: Reduced carbs deplete glycogen, releasing water (3-5 lb in week 1)
Improved insulin sensitivity: Especially beneficial for prediabetes and metabolic syndrome
Reduced cravings: Stable blood sugar means fewer energy crashes and sugar cravings

Low carb vs. other diets

Compare low carb with other popular approaches:

Keto diet — more extreme (under 50g carbs), faster initial loss
Mediterranean diet — includes more carbs from whole grains
Paleo diet — eliminates grains and dairy but allows fruit carbs
Best diet comparison — all diets compared by science

Health benefits beyond weight loss

Blood sugar: Reduces fasting glucose by 10-15%
Insulin sensitivity: Improves by 20-30%
Triglycerides: Reduces by 20-40%
HDL cholesterol: Increases by 5-15%
Blood pressure: Reduces by 3-5 points
Visceral fat: Specifically reduces belly fat

Common low carb mistakes

Eating too much protein: Excess protein converts to glucose — moderate your portions
Not eating enough vegetables: Low carb does not mean no vegetables — eat plenty
Too many processed low-carb foods: Low-carb bars and shakes are still processed
Not getting enough electrolytes: Sodium, potassium, and magnesium are essential
Eating too many calories: Low carb still requires a calorie deficit for weight loss
Giving up too early: First 1-2 weeks can be tough — push through the adaptation

Combining low carb with GLP-1 medications

Low carb diets and GLP-1 medications are a powerful combination because they target weight loss from complementary angles:

Both reduce insulin — the fat-storage hormone
GLP-1 medications reduce appetite, making low carb easier to maintain
Low carb provides the metabolic environment for fat burning
GLP-1 medications improve insulin sensitivity at the cellular level
Both specifically target visceral (belly) fat
Clinical trials show 15-22% weight loss with this combination

Maximize your low carb results

GLP-1 medications + low carb = maximum fat loss. Check if you qualify.

The bottom line

A low carb diet (50-130g carbs per day) is one of the most effective and sustainable approaches for weight loss. It produces 2-3 times more weight loss than low-fat diets in the first 6 months by reducing insulin, increasing fat burning, and naturally reducing calorie intake. It is more flexible than keto and easier to maintain long-term. For maximum results, combine with a calorie deficit, adequate protein, regular exercise, and GLP-1 medications — which can produce 15-22% weight loss in clinical trials.
