What can I do to lose only fat?


Hello Dietitian Liu Qiaoyun,
It's me.
Thank you for taking the time to answer my questions.
Since November 3, 2014, I have been following a weight loss method that includes controlling my diet (low-calorie diet) and doing aerobic exercises (stretching, aerobic dance, jogging, stair climbing, and targeted exercises).
I have lost 9 kg over the past year and three months.
I currently weigh 49 kg, my height is 158 cm, and my waist circumference is 28 inches.
I have found it difficult to lose more weight recently.
I have been doing kickboxing for nearly two months (three times a week, one hour each session), but my body fat percentage measured at the hospital is 28%.

Therefore, I would like to request a dietary plan that includes foods that can help with fat breakdown, along with a calorie calculation and portion guide.
Could you please email it to me at [email protected]?
Additionally, what should I do during my weight loss process to ensure that I only lose fat? Thank you for taking the time to respond.

Hello.
From your body fat data, it appears that your ratio is still somewhat high, so it doesn't seem like your muscle mass is at a level where you can't lose any more weight.
However, I personally feel that the exercises you mentioned may not significantly help with your waistline (at least not boxing).
I assume you are working out at a gym or with an instructor, so perhaps you could ask them for advice on how to slim down your waist.

Regarding foods that aid in fat breakdown, to my knowledge, there isn't a specific diet that has been proven to do this.
If such foods existed, it would likely be widely reported in the news, and we wouldn't have to worry about weight loss issues.
There are, however, food calorie calculators and portion guides available, but since there is a lot of information, I don't have an electronic file.
Please send me your address via email, and I will mail it to you.

Ultimately, the most effective strategy is simply to eat less.
As long as you reduce your intake (especially fats and sugars), gaining weight becomes difficult.
Additionally, regularly monitoring your weight is important; if you gain weight, reduce your intake until you return to your previous weight before eating more.
With dedication, even if you can't lose weight, you can certainly avoid gaining more.
Let's encourage each other! Best, Qiaoyun 11/17.

To effectively lose fat while preserving muscle mass, it's essential to adopt a comprehensive approach that includes a balanced diet, appropriate exercise, and lifestyle changes. Here’s a detailed guide based on current understanding in the field of nutrition and exercise science.


1. Understanding Fat Loss vs. Muscle Loss
When you aim to lose weight, it’s crucial to understand that not all weight loss is equal. Ideally, you want to lose fat while maintaining or even building muscle. Muscle is metabolically active tissue, meaning it burns calories even at rest, which is beneficial for long-term weight management.

2. Caloric Deficit with Nutritional Balance
To lose fat, you need to create a caloric deficit, meaning you consume fewer calories than your body burns. However, this deficit should not be so extreme that it leads to muscle loss. A moderate caloric deficit of about 500 calories per day is often recommended, which can lead to a safe weight loss of about 0.5 to 1 kg (1 to 2 pounds) per week.

Dietary Recommendations:
- Protein Intake: Increase your protein intake to help preserve muscle mass. Aim for about 1.6 to 2.2 grams of protein per kilogram of body weight. High-protein foods include lean meats, fish, eggs, dairy products, legumes, and plant-based proteins.

- Healthy Fats and Carbohydrates: Include healthy fats (like avocados, nuts, and olive oil) and complex carbohydrates (like whole grains, fruits, and vegetables) in your diet. These provide essential nutrients and energy for workouts.

- Hydration: Stay well-hydrated, as water is crucial for metabolic processes and can help control hunger.


3. Incorporating Exercise
Exercise plays a vital role in fat loss and muscle preservation. A combination of resistance training and cardiovascular exercise is most effective.

- Resistance Training: Aim for at least 2-3 sessions per week. Focus on compound movements (like squats, deadlifts, bench presses) that work multiple muscle groups. This not only helps in building muscle but also increases your metabolic rate.

- Cardiovascular Exercise: Incorporate moderate to high-intensity cardio sessions (like kickboxing, running, or cycling) 3-5 times a week. Aim for at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous activity per week.

- High-Intensity Interval Training (HIIT): This can be particularly effective for fat loss while preserving muscle. HIIT involves short bursts of intense exercise followed by rest or lower-intensity exercise.


4. Post-Workout Nutrition
After workouts, especially resistance training, it’s crucial to consume a meal or snack that includes both protein and carbohydrates. This helps in muscle recovery and replenishes glycogen stores. A protein shake with a banana or a meal containing chicken and sweet potatoes can be effective.


5. Monitoring Progress
Keep track of your body composition rather than just weight. Use methods like body fat percentage measurements or progress photos to assess changes. This will help you understand if you are losing fat while maintaining muscle.


6. Lifestyle Factors
- Sleep: Aim for 7-9 hours of quality sleep per night. Poor sleep can hinder recovery and affect hormones that regulate hunger and metabolism.

- Stress Management: High stress can lead to hormonal imbalances that promote fat storage. Incorporate stress-reducing activities such as yoga, meditation, or leisure activities.


Conclusion
In summary, effectively losing fat while preserving muscle involves a balanced approach that includes a moderate caloric deficit, high protein intake, a combination of resistance and cardiovascular training, and attention to recovery and lifestyle factors. Remember, patience and consistency are key. Rapid weight loss often leads to muscle loss, so aim for gradual changes that you can maintain long-term. If you have specific dietary needs or health concerns, consider consulting with a registered dietitian or nutritionist for personalized guidance.
