Community + inspiration, fewer decisionsWhy the SUN Minimeal Fatburn Challenge works better than any classic diet
The 5 most frequent questions – simply answered.
Why am I not hungry despite 800 kcal?
Because SUN Minimeal doesn't let your body go hungry, but nourishes it. The balanced combination of high-quality proteins, fats, and complex carbohydrates keeps your blood sugar stable – eliminating cravings.
How can my body get everything it needs with so few calories?
It's not about how many calories you consume, but how many nutrients. MINIMEALS provide all essential nutrients in the right amount, ensuring your body is optimally nourished, even with reduced calorie intake.
Am I losing muscle or really just fat?
With a calorie intake of 800 kcal with MINIMEALS, you usually lose mainly fat and not muscle. MINIMEALS contain a sufficient amount of protein (33%), which is important to minimize muscle breakdown. A complete protein supply helps maintain muscle mass during a diet.
How does this affect my digestion and how I feel overall?
MINIMEALS contain prebiotic fiber that supports gut flora and promotes digestion. This can lead to better nutrient absorption and fewer digestive issues. MINIMEALS are designed to be easily digestible. Many users report not feeling heavy or bloated after consumption, which enhances overall well-being.
Can I really keep this up – without cooking, stress, or effort?
Yes, you can easily stick to your diet with MINIMEALS, without cooking, stress, or a lot of effort. With MINIMEALS, you get nutrients in pre-defined portions, which helps you control calorie intake and avoid overeating; you don't have to worry about putting your meals together. Plus, you can take MINIMEALS anywhere – whether in the office, when traveling, or at home. This makes it easy to adapt your diet to your lifestyle. The SUN community (free platform for customers) offers support and tips, which can help you stay motivated and achieve your goals.
Why the Fat Burn Challenge Works
Many programs fail not due to a lack of motivation but because of unclear structure and unbalanced supply. SUN relies on clear portions, reduced calories, and nutrient density. The basis of a CRON diet:
-
Coordinated nutrient supply: closes typical supply gaps*
-
A MINIMEAL - simple routine: portioned and always with you
-
Reduced Calories, Stable Energy: Fewer calories with improved nutrient supply enable ketosis.
Fewer calories – without sacrificing the essentials.
the testers felt more energy and satiety
experience less cravings despite calorie reduction.
gain more time in everyday life and feel no sacrifice.
report more power and better focus.
