TDEE determines how many calories you burn daily. Understanding it is the foundation of any weight management strategy — whether losing, gaining, or maintaining.

calories.md reviews the science behind intermittent fasting — what works, what doesn't, and who should avoid it.

calories.md breaks down protein requirements by goal — weight loss, muscle building, aging well — with practical food sources and daily targets.

calories.md shares proven strategies for creating a calorie deficit without tracking every bite — practical approaches that work in real life.

calories.md explains macronutrient tracking in plain English — what macros are, how to set targets, and whether counting macros beats counting calories.

calories.md explains the NOVA classification, why ultra-processed foods drive overeating, and practical swaps for a healthier diet in 2026.

FDA rules let a label understate calories and still comply. Restaurant menus are accurate on average but wrong on individual items. Wrist trackers missed energy burn by 27% to 93% in a Stanford study. Here is how to count anyway.

Roughly 300 to 500 net calories for most adults, and body weight matters far more than pace. Here is the arithmetic behind the number, why your tracker inflates it, and what net versus gross burn means for weight loss.

About 500 calories a day, by the classic 3,500-calorie rule. That target works at the start, then overestimates. Here is where the rule comes from, why weight loss slows, and how to set a deficit from your own maintenance number.

Alcohol has 7 calories per gram, and a standard drink carries about 100 to 150. Here is how your body handles them, why they count, and how to track them.

A true calorie deficit cannot add body fat. Scale gains usually come from water shifts or tracking gaps. Here are the causes, the numbers, and how to check.

Total calories decide weight gain, not the clock. But a controlled trial found late eating doubled hunger and cut daytime calorie burn by 59 kcal. Here is what matters.

Breastfeeding burns about 500 to 540 calories a day in the first 6 months. U.S. guidelines say eat 330 to 400 extra. Here is the math and the evidence.

Cold wins, but only by about 190 calories a day in lab studies at 16 to 19°C. Sweating burns almost nothing. Clothing and heating erase most of the gap.

No single calorie number protects muscle. Research supports a deficit near 500 kcal a day, about 0.7% of body weight lost per week, and high protein intake.

Smartwatch calorie errors top 30% for every brand. Pooled studies show a slight undercount, but one 2026 study found weight training readings about double.

USDA lists raw white rice at 365 calories per 100 g and cooked rice at 130. Weigh raw when you can, and match the database entry to the state you weighed.

An overnight 2 to 3 pound jump is water, sodium, glycogen and gut contents, not fat. Three pounds of fat would need about a 10,500 calorie surplus.

Digestion burns about 10% of what you eat, around 200 calories on a 2,000 calorie day. Protein costs 20 to 30% of its calories, fat 0 to 3%. What moves the number.

Only if your calorie target leaves exercise out. Studies show people offset about 28% of added activity, so eat back part, not all, and adjust by weight trend.
