Welcome to the My Slim Tools FAQ page! We’ve compiled answers to the most common fitness, calorie, and weight-loss questions to help you stay informed and motivated. All information is based on peer-reviewed studies and practical fitness strategies.
1. What is a calorie deficit?
A calorie deficit happens when you consume fewer calories than your body burns, which forces your body to use stored fat for energy. It’s one of the most effective ways to lose weight safely.
2. How do I calculate my TDEE?
Your Total Daily Energy Expenditure (TDEE) is the total number of calories your body burns daily. Use our free TDEE Calculator to get personalized results.
3. How big should my calorie deficit be?
For safe, sustainable fat loss, aim for a deficit of 250–500 calories per day. Larger deficits can result in muscle loss and reduced energy levels.
4. What are macros and why do they matter?
Macros — short for macronutrients — are proteins, fats, and carbohydrates. Balancing your macros helps you lose fat, preserve muscle, and maintain energy. Try our Macro Split Calculator to find your ideal balance.
5. Are all calories the same?
Not exactly. While calories measure energy, the source matters. Protein, carbs, and fats impact hunger, hormones, and metabolism differently.
6. Do I need to exercise to lose fat?
No — fat loss happens through a calorie deficit. But adding strength training and cardio can speed up results and improve overall health.
7. Are keto and intermittent fasting good for fat loss?
They can be effective tools, but they’re not magic solutions. Choose the approach that fits your lifestyle best. Check out our keto-friendly recipes for ideas.
8. How long does it take to see results?
Most people notice changes within 3–6 weeks if they follow a consistent plan with a proper calorie deficit and exercise routine.
