How fast can I lose or gain?

You choose a pace as a share of your body weight per week, on a slider marked slow and steady, recommended and fast. Tone shows the date you’d reach your goal at that pace.

To keep a plan safe, Tone has limits:

• Losing weight goes up to 1% of your body weight a week, less if you’re closer to a healthy weight.
• Gaining goes up to 0.5% a week for Gain weight, and a little less for Build muscle.
• Calories never go below 1,200 a day for women or 1,500 for men.

If a limit changes your plan, Tone tells you why.
