A deficit that's too steep
Very aggressive diets make it harder to fuel training and hold on to strength. Faster isn't always better.
For people losing weight on their own
Whether you're counting calories, following a plan or just eating less, a calorie deficit doesn't only take fat. How much muscle you keep depends mostly on three things you control: protein, strength training, and how fast you go.
About ¼
of the weight lost through dieting is fat-free mass, according to a widely cited rule of thumb. The same review stresses it varies a lot from person to person.
What makes it hard
Very aggressive diets make it harder to fuel training and hold on to strength. Faster isn't always better.
Walking and running are great for health, but lifting is what tells your body to keep its muscle.
The scale can't separate fat from muscle or water. A strength trend tells you much more.
How Dyadfit helps
Eat the foods you like. Dyadfit gives you a daily protein range and shows how far you are from it.
Full-body sessions of about 30 minutes, with or without a gym, that get harder only when you're ready.
If weight is dropping fast while strength slides, the weekly check tells you to ease off a little.
To lose fat while keeping as much muscle as possible, focus on three things: eat enough protein, do strength training at least twice a week (ideally three times), and lose weight at a steady pace of about 0.5–1 kg (1–2 lb) a week. Some lean mass loss is normal with any weight loss, but these habits help you keep more.

The clearest at-home sign that you're losing muscle rather than fat is strength going backwards for several weeks while your weight falls. Other clues include very fast weight loss, a scale that drops while your waist barely changes, and everyday tasks feeling harder. The scale alone can't tell you, so check weight trend, strength and waist or smart-scale trend together each week.

Smart scales are usually accurate for body weight but not for body fat. Studies comparing consumer scales with DXA scans found they underestimated fat mass and could be off by several kilograms for an individual. Treat the body-fat number as an estimate: use one scale in the same conditions, compare weekly averages, and pair that trend with your weight and strength progress.

Questions
The US CDC notes that people who lose about 1 to 2 pounds (roughly 0.5 to 1 kg) a week are more likely to keep it off. A steady pace also leaves room to train and eat enough protein.
Some form of strength training is the most reliable way to keep muscle while you lose weight. It can be bodyweight moves or light dumbbells at home. The WHO recommends muscle-strengthening activity on at least 2 days a week.
No. You can keep using whatever method works for you. Dyadfit focuses on protein, strength and the weekly muscle check.
