Caloric deficit<\/strong> It's the only real way to lose fat. You can change your diet, cut out bread from dinner, or train twice as much, but if at the end of the day you don't expend more energy than you consume, the fat stays where it is.<\/p>\n

The problem isn't going into a calorie deficit. The problem is getting out of it with your muscle intact. An overly aggressive cut might lead to rapid weight loss, but it will destroy muscle mass, strength, and motivation to train. In this guide, you'll learn how many calories to cut, how to distribute your macronutrients, what to do at the gym, and what signs indicate you're losing what took years to build.<\/p>\n

What is a calorie deficit?<\/h2>\n

A calorie deficit means consuming less energy than you expend throughout the day. And that expenditure isn't just from exercise: it includes your basal metabolic rate, food digestion, the steps you take, and any everyday movement.<\/p>\n

When energy is lacking, the body draws on its reserves. Most of it comes from the adipose tissue<\/a>, Which is exactly what you're looking for. But muscle is also tissue and can also end up being used as fuel if conditions aren't favorable.<\/p>\n

That's the key to the whole definition. It's not about losing weight, but about choosing how much weight you lose. And that depends on three specific factors: the extent of the reduction, the protein you eat, and the level of stimulation you maintain at the gym.<\/p>\n

How many calories to cut to get defined<\/h2>\n

Significantly less than what is usually recommended. A practical guideline is to subtract between 10 and 20% of your total energy expenditure. With that margin, you'll lose between 0.5 and 1% of your body weight per week.<\/p>\n

For someone weighing 80 kilos, that rate equates to losing between 400 and 800 grams each week. It sounds slow, but in three months that's between 5 and 9 kilos of fat with virtually no muscle mass left. The more defined you already are, the more conservative the weight loss should be.<\/p>\n\n\n\n\n\n\n\n
Starting point<\/th>\nRecommended cropping<\/th>\nWeekly loss<\/th>\nRisk of muscle loss<\/th>\n<\/tr>\n<\/thead>\n
High fat (more than 25 % in men or 32 % in women)<\/td>\n-20 to -25 %<\/td>\n0.8-1 % of the weight<\/td>\nLow<\/td>\n<\/tr>\n
Medium fat (15-25 % in men or 25-32 % in women)<\/td>\n-15 to -20 %<\/td>\n0.5-0.8 % of the weight<\/td>\nModerate<\/td>\n<\/tr>\n
Already quite defined (less than 15 % or 25 %)<\/td>\n-10 to -15 %<\/td>\n0.3-0.5 % of the weight<\/td>\nHigh<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

If you don't know your calorie expenditure, don't struggle with complicated formulas. Eat the same thing for two weeks, weigh yourself every morning on an empty stomach, and calculate the weekly average. If your weight doesn't change, those are your maintenance calories. From there, subtract 300 kcal and see what happens for two weeks.<\/p>\n

In a calorie deficit, the goal of the gym changes: it's no longer about progressing, it's about maintaining the strength you had.<\/figcaption><\/figure>\n

Protein and macros: muscle insurance<\/h2>\n

Total calories determine how much fat you lose. Macronutrient distribution determines whether you also lose muscle. These are the key factors that work best during a cutting phase.<\/p>\n
