Short Summary
Main recommendation: Most people on a low-carb or keto diet do not need to count calories at first, because the diet reduces hunger and calorie intake automatically, but counting calories becomes useful when weight loss stalls and hunger or eating habits are still driving intake. Dr. Eric Westman explains that calories still matter on keto, but they are reduced mainly by eating less rather than by any large metabolic boost.
Key Points
- Dr. Westman says keto works mainly because it reduces calorie intake, since he says the metabolic advantage over a low-fat diet is only about 100 calories per day.
- Hunger normalizes on low-carb eating, so most people eat less without tracking, and the body can then access fat stores.
- If hunger persists, check medications such as antidepressants, insulin, prednisone or other steroids, and steroid nasal sprays, plus stress or emotional eating of carbs.
- Dr. Westman says a stalled scale can reflect water weight rather than no fat loss, most often in the first one to two months or in people taking a diuretic, so he suggests clothing fit and inches as useful signals.
- Exercise and metabolic rate can change how hungry someone feels, so hunger alone may not guide intake for everyone.
Details Worth Noting
- Concrete instructions: If weight loss has stopped after the early period, write down the 10 to 20 foods you eat, look up their calories, and total the day's intake to see how much you are eating. Then reduce from there. Formulas, a calorie-tracking app, a paper calorie log, or a search or voice-assistant lookup can estimate what you should be eating on average.
- Be especially careful with cream, cheese, and mayonnaise, since calories add up quickly from these foods; Dr. Westman says his program strictly limits them for this reason.
- Some people who followed the program closely still did not lose weight because of exercise-related hunger, so tracking may be needed even when the plan is followed well.
- Westman mentions 12 years of clinical experience and describes the metabolic advantage of low-carb versus low-fat diets, in his view, as small.
- Modern food availability is a long-term challenge, which is why ongoing attention to intake may be needed.
Bottom Line
Keto usually reduces calories without counting them, but when progress stalls, measuring intake and watching high-calorie add-ons becomes the practical next step.
