The old version of this post asked whether the Atkins diet is right for you, and answered with a list of reasons to try it, including a family history of diabetes, being overweight and having certain eating habits. Some of that advice is sensible, and some goes too far. This rewrite keeps the questions and fixes the parts that overreach.

What is your dieting history?

The old post suggests writing down every diet you have tried, what worked, what did not and why you stopped. That is a good exercise. It also says that if low-fat diets have worked well for you and low-carb diets have not, Atkins is probably not for you. The research backs the idea that personal fit matters: in a 12-month trial of 609 adults, a healthy low-carb diet and a healthy low-fat diet produced similar weight loss on average (6.0 kg compared with 5.3 kg, a difference that was not significant), which suggests that a plan you can keep following matters more than the label on it. Read the trial abstract.

Are you “carb sensitive”?

The old post lists signs: feeling hungry right after meals, strong urges to eat during the day, feeling dizzy, foggy and tired without sugar, and feeling sluggish after a meal rich in carbohydrates. “Carb sensitivity” is an informal term, not a diagnosis, and the same symptoms can come from skipped meals, poor sleep or medical problems. MedlinePlus lists anemia, thyroid disease, diabetes, sleep disorders and depression among the causes of fatigue. If you often feel like this, ask your doctor for a check before blaming carbohydrates.

What does your medical history say?

The old post said that if you have prediabetes or diabetes, a low-carb diet such as Atkins may be right for you, and that a family history of diabetes can create a need for it. The truth is more careful. The American Diabetes Association’s 2019 consensus report says that for select adults with type 2 diabetes who are not meeting blood sugar targets, or for whom reducing medicine is a priority, low- or very-low-carbohydrate eating is a viable approach. It also says that a very-low-carb plan can cause fluid loss and a quick drop in blood sugar, so you need advice from a knowledgeable practitioner at the start to prevent dehydration and low blood sugar. The ADA’s 2019 standards of care did not recommend low-carb plans for pregnant or lactating women, people with or at risk of disordered eating, or people with kidney disease, and said to use them with caution with SGLT2-inhibitor drugs because of the risk of ketoacidosis (check the current edition of the standards). Our post on Atkins and diabetes looks at this in more detail, and you can read the ADA consensus report.

Does being overweight make Atkins a better fit?

The old post says that the more overweight you are, the more likely you are to have high blood pressure, high triglycerides and high blood glucose, which is true. But it is not a reason to choose one diet over another. The National Heart, Lung, and Blood Institute notes that adults with overweight or obesity can lower LDL cholesterol and raise HDL by losing only 3 to 5 percent of their weight, whichever way they do it. Pick the plan you can follow, and ask your provider to check your blood pressure, cholesterol and glucose while you lose weight.

Can you live with the rules?

Think about the practical side. The first two weeks can bring headaches, tiredness and constipation, and you need to count carbohydrates. Atkins currently offers plans at different carbohydrate levels (about 20, 40 or 100 grams of net carbs a day, according to its website), and the old post mentioned a “modified” version for people who had bad experiences with both low-fat and low-carb diets. See the Atkins diet basics and Atkins induction rules to find out what is involved, and common mistakes Atkins dieters make for traps to avoid.

What should you do next?

Talk to your doctor if you have diabetes, kidney disease, heart disease or high cholesterol, or if you take regular medication. Write down your answers to the questions above, choose a start date and plan your meals before you begin. If Atkins is not right for you, that is fine; there are other ways to lose weight and keep it off.
