Key Takeaways
Does your life resemble a typical comparison of periods of a strict diet and uncontrolled eating? The most important thing is to realize that success in reduction is not about quick weight loss, but a long-term lifestyle change and increased dietary awareness. Are you still struggling with the yo-yo effect due to restrictive diets? Perhaps it's time to try a different approach and finally get rid of the extra weight for good. If you've tried everything and still can't lose weight effectively, learn about four principal rules that will help you avoid failure.
Meal Plan

Want to apply these guidelines in your daily diet?

Our smart diet generator creates a tailored meal plan in 3 minutes based on the recommendations in this article.

Implement changes in stages

One of the main reasons for your failed attempts is delivering too many stimuli at the same time. Have you never participated in any training before, have you not followed the rules of any diet, have you not restricted simple sugar and alcohol intake? No wonder that if you suddenly start exercising five times a week and following a strict diet, your body will strongly resist. Utilize the strategy of small steps and implement changes gradually, but consistently. Your body, which is not accustomed to physical exertion, reacts quickly, even to small stimuli. Therefore, it is not advisable to jump into deep water, as the likelihood of failure is much greater. Create a step-by-step strategy and implement it step by step, every week present a new challenge, for example: a) limit intake of sweets, strive to follow the guidelines of the Institute of Food and Nutrition; b) exercise every other day for an hour; c) plan a diet with a negative calorie balance; d) add one training session per week; e) completely eliminate sweets from the diet; f) exercise daily; g) cut out another 200 kcal from the diet.

Enhance your metabolic rate

Long-term abstinence from food is the simplest way to decrease your metabolic rate. When the body does not receive nourishment for about six hours, it starts to activate its defense mechanisms, assuming it is being starved and needs to start saving energy. Therefore, the strategy of eating less, but more often, seems to be the best solution. According to recommendations, we should consume four to five meals every three to four hours per day. Another good suggestion is to consume protein at every meal, as this enhances the feeling of satiety.

Avoid attempting rapid weight loss

During the weight loss period, remember that not only is a high leptin intake a factor that can stimulate your diet from time to time, but also a long-term decrease in blood fluid levels, which is known as a cheat meal. This often occurs in long-lasting reduction, which in turn can prevent further weight loss. However, make sure that a body weight loss dependent on a healthy diet is not converted into a weight loss process, which will result in a rapid physical process. It is essential to remember that not only a high leptin level can stimulate food intake, but a long-term decrease in blood fluid levels also plays a role. This state often occurs in long-lasting weight reduction, which can make it challenging to lose further weight. However, avoid turning a cheat meal into a habit that occurs too frequently, such as a cheat week or cheat month. If you did not gain 20 kilograms overnight, do not expect even the best diet and training program to let you burn it off in one day. The pace of weight loss is an individual process and depends on various factors, such as the amount of body fat, gender, and the degree of sensitivity to training and diet. For example, a 90-kilogram man with 20% body fat can lose about 1 kilogram of fat per week in physiological conditions. In contrast, a 50-kilogram woman with about 14% body fat can lose about 0.5 kilograms of fat per week in physiological conditions. It is easy to see that if the weight is lost too quickly, a significant amount of muscle tissue will also be lost. The rate of weight loss also depends on the degree of negative energy balance in the daily diet.

Designing nutritional plans and strategy planning

For many people, a diet is associated with starvation and eating a daily piece of dry bread with a cup of black coffee. However, nothing is more misleading. Without adapting to nutritional rules, the body will respond well to even small restrictions. Initially, simply eliminating simple sugars, reducing alcohol consumption, or giving it up will have satisfactory results. Designing a diet should only be the next step. A well-planned diet should have a coherent strategy. Determine therefore, what your actions will be when weight loss ceases, and do not be surprised. A good decision is to set a low negative calorie balance, subtracting 200-500 kcal from the total energy requirement (including basic needs such as breathing or organ function; energy expended on daily living activities such as brushing teeth; and physical activity), to gradually increase it. In case of considering the introduction of dietary restrictions (applying an appropriate diet), it is advisable to consult a specialist, such as a dietitian, who will help in creating a diet and determining the calorie requirement, so that the reduction is not associated with a deficiency in nutrients.
