Walking before breakfast may burn slightly more fat. The most important factor is consistency, so choose the time that fits your schedule best.
Focus on protein first. Aim for 0.8 to 1 gram of protein per kilogram of body weight each day. For a 75kg person, that’s 60 to 75 grams daily.
Dropping below 1,200 calories per day for women or 1,500 for men causes problems. Your body goes into conservation mode, slowing your metabolism to protect itself.
Processing protein takes more energy to digest than carbs or fats. This “thermic effect of food” (TEF) means you’re burning more calories simply by eating.
Yeah, yeah, you’ve heard it all before: “calories in, calories out.” But it’s not enough to simply maintain a calorie deficit. To lose 1kg of fat per week (that’s roughly 2.2 pounds, a firm, healthy target), you need a consistent deficit of around 1100 calories each day. Fat, fat is like a storage tank that contains about 7,700 calories of energy per one kilo. So doing simple math: 7,700 calories / 7 days = 1,100 calorie deficit per day.
