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
Cutting calories? Keep the muscle you've got.
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
The usual obstacles
Cardio without strength
Walking and running are great for health, but lifting is what tells your body to keep its muscle.
Judging progress by the scale alone
The scale can't separate fat from muscle or water. A strength trend tells you much more.
How Dyadfit helps
Your plan, in three habits
The same three habits for everyone, tuned to where you're starting from.
A protein range, not a meal plan
Eat the foods you like. Dyadfit gives you a daily protein range and shows how far you are from it.
Strength that fits around life
Full-body sessions of about 30 minutes, with or without a gym, that get harder only when you're ready.
A pace check
If weight is dropping fast while strength slides, the weekly check tells you to ease off a little.

Questions
Common questions
How fast should I lose weight to keep muscle?
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.
Do I have to lift weights?
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.
Is Dyadfit a calorie counter?
No. You can keep using whatever method works for you. Dyadfit focuses on protein, strength and the weekly muscle check.
