In January 2026, HHS Secretary RFK Jr. and USDA released the most significant reset of U.S. nutrition policy in history. More protein. Less refined carbs. The science that keto practitioners have known for decades is now federal policy.
Years before the government reset its guidelines, twelve researchers made the peer-reviewed case for exactly this shift: "Alternative Dietary Patterns for Americans: Low-Carbohydrate Diets", Volek JS, Phinney SD, Krauss RM, et al., Nutrients, 2021.
Low-carbohydrate diets are grounded across the time-span of human evolution, have well-established biochemical principles, and are now supported by multiple clinical trials…

Despite this evidence base, low-carbohydrate diets are not reflected in the [Dietary Guidelines for Americans].

For the first time in U.S. history, protein and healthy fats sit at the top. Refined carbohydrates are dramatically reduced. The old food pyramid, the one that made Americans sick, has been officially retired.
Protein and healthy fats are essential and were wrongly discouraged in prior dietary guidelines. We are ending the war on saturated fats.

We are calling for a dramatic reduction in the consumption of highly processed foods laden with refined carbohydrates, added sugars, excess sodium, unhealthy fats, and chemical additives.

What we're stressing is that people should be eating protein. Proteins should be served with no or limited added sugars, chemical additives, refined carbohydrates or starches.

The 2025–2030 Guidelines reestablish food, not pharmaceuticals, as the foundation of health and reclaim the food pyramid as a tool for nourishment and education.

The ketogenic diet has been built on exactly these principles for decades: high protein, healthy fats, dramatic reduction of refined carbohydrates, and zero added sugar. The 2025–2030 Dietary Guidelines don't just validate low-carb eating: they make it the new federal standard.
While the federal guidelines stop short of recommending full ketosis, the macronutrient framework they now endorse (high protein, healthy fats as priority, dramatic reduction of refined carbs, zero added sugar) is structurally aligned with ketogenic eating. The gap between federal nutrition policy and the ketogenic diet has never been smaller.

A meta-analysis of 13 randomized controlled trials (1,415 participants, followed for 12 months or longer) found that people assigned to a very low-carbohydrate ketogenic diet lost more weight than those on low-fat diets, with lower triglycerides and diastolic blood pressure and higher HDL cholesterol. LDL cholesterol also rose slightly on the ketogenic diet.

A 24-week randomized controlled trial in 120 overweight adults with high blood lipids compared a low-carbohydrate ketogenic diet with a low-fat, reduced-calorie diet. The low-carbohydrate group lost more weight (12.9% vs. 6.7% of body weight), saw larger drops in triglycerides and larger rises in HDL cholesterol, and more of them finished the study (76% vs. 57%). LDL cholesterol did not differ significantly between the groups.

A study of 20 elite ultra-endurance athletes found peak fat oxidation was 2.3 times higher in those keto-adapted for an average of 20 months than in athletes eating a high-carbohydrate diet, while muscle glycogen use and recovery during and after a 3-hour run were similar in both groups.

An NIH-published review concluded that the current dietary guidelines provide "little flexibility" in carbohydrate distribution and that the argument for a low-carbohydrate dietary pattern is compelling given the failure of existing guidelines to address the needs of Americans with obesity, metabolic syndrome, and T2D.

The guidelines changed. Now change how you track. KetoNoir's AI-powered app is built on exactly the science the federal government just confirmed. Available now on iOS and Android.
KetoNoir calculates your Glucose-Ketone Index automatically. That number only means something when the readings behind it are real: blood glucose and blood ketones, not a urine strip that fades by the afternoon.
Urine strips measure spillover, not what is in your blood, and they lose accuracy within days of opening. A real GKI needs blood glucose and blood ketones. Keto-Mojo is the meter we point people to for exactly that.
