Calorie Deficit: How It Really Works, and How to Build One You Can Live With

A caloric deficit is simply a situation in which the body spends more energy than it receives from food, and therefore makes up the difference from its stores. This is the only mechanism that is really responsible for weight loss - any diet that works, of any kind, works because it created a deficit, even if it doesn't call it that.

But "it's simple" and "it's easy" are not the same thing. The hard part isn't the bill-it's maintaining that bill for months without being hungry, irritable, and bored. Most of this guide is about just that.

This guide is general information only and not personal medical or nutritional advice. If you have a medical condition, are taking medication, are pregnant, or have a history of an eating disorder - you should build the menu with a professional.

How many calories do you really need?

Any calculator you find gives an estimate, not a measurement. It first calculates your resting metabolic rate (BMR)-how much your body burns if you lie down all day-and then multiplies it by an activity factor to get your total daily expenditure. This estimate can be off by 200-300 calories in each direction, so it is a starting point and not the truth.

• Start from the number the calculator gave, and subtract 15%-20% from it. This is a reasonable deficit that allows for a loss of approximately 0.5% of body weight per week.
• Do not go below 1200 calories for women or 1500 for men without professional guidance. Below that it is very difficult to supplement vitamins and minerals.
• Follow for two or three weeks and then buy. If the weight does not move at all after three consistent weeks - reduce another 100-150 calories. If it drops too fast and you are exhausted - add more.
• The daily weighing is a lie. Measure weekly average against weekly average, not day against day. Salt, carbohydrates, circulation and the amount of water change the number by a kilo and a half easily.

The protein is the most important component of the deficit

In a deficit, the body looks for energy, and part of it will be happy to take from muscle. Sufficient protein, along with resistance training, is what signals him to take it mostly from fat. In addition, protein is the component that is the most satisfying for a long time - that is, it helps you twice.

• A reasonable goal: 1.6-2.2 grams of protein per kilogram of body weight per day. In a deep deficit, you should aim for the upper part of the range.
• Spread over the day - 25-40 grams at each meal works better than 100 grams in one evening.
• Cheap and convenient sources: chicken breast, tuna in water, eggs and egg whites, low-fat cheeses, Greek yogurt, cottage cheese, tofu and legumes.

Volume and satiety: the trick that makes all the difference

Your stomach doesn't count calories - it feels volume. 300 calories of a handful of almonds disappear in two minutes; 300 calories of cauliflower soup with chicken breast and salad fills an entire plate. That's why the exact same deficit can feel completely bearable or impossible, depending on how you put it together.

• Unlimited vegetables in almost every meal - they add volume, fiber and water for almost no calories.
• Choose the full form of the food: a whole apple instead of juice, a baked potato instead of mashed potatoes, meat instead of sausage.
• Soups and dishes with a lot of liquid are more satisfying than the same ingredients in dry form.
• Fat is the most caloric component - 9 calories per gram. You don't need to eliminate it, but a spoonful of olive oil that is "roughly" poured into the pan is 120 calories that have not been counted.
• Liquid calories are almost never registered by the body as satiety. Coffee with sugar, juice and alcohol are the easiest place to save without feeling it.

Why is the weight stuck?

Almost always one of four reasons, in this order:

1. You eat more than you think. This is by far the most common reason - bites while cooking, sauces, oil, a teaspoon of sugar here and there. One week of accurate weighing usually solves the mystery.
2. You move less. In a deficit, the body saves energy without asking you: less unconscious movement, less stairs, more sitting. Counting steps reveals this immediately.
3. The expenditure decreased with the weight. A lighter body burns less. The deficit that suited you 8 kilos ago is no longer the same deficit.
4. Water retention hides real decline. A change in salt, training or cycle can hide two weeks of progress. The weekly average will show this, Tuesday's weight will not.

Some rules that last a long time

• Don't build a menu you hate. A perfect menu that breaks in the third week is worse than a reasonable menu that lasts six months.
• Leave room for 10%-15% calories for "fun". It's not a sin, it's a policy that prevents outbreaks.
• Cook it yourself. The caloric gap between a home dish and an equivalent dish outside is usually 30%-50%.
• Resistance training two to three times a week. It does not burn many calories, but it is the one that keeps the muscle.
• sleep A short night increases appetite and decreases satiety - it's not in your head, it's hormonal.
• take breaks After 10-12 weeks in a deficit, a week or two in caloric balance refreshes both the head and the appetite.
