According to the NHS, an adult is overweight when their body-mass index (BMI) is 25 or above. Being overweight can cause health problems such as diabetes and heart disease.

A safe rate of weight loss is between 0.5 and 1kg per week, so take it steadily and don't try to crash diet. You don't want to yo-yo back once you get there.

  2. Get your BMI down below 25
  3. Keep it there for a month

Recent advice

“When I first started to set diet and fitness goals back in October, I was mainly concerned about weight. By February I had lost more than 23 pounds, and I hit my initial goal weight of 163 pounds. As I continued, I focused more on body fat percent and BMI. Furing the month of April I have maintained a BMI of under 25 percent. I want to set a new goal to drop that down to 22 percent.”

Danyka P Get your BMI below 25 Challenge

Contributorgold Danyka P I guess I have calculated this wrong. Just recalculated and my BMI is at 24% and my weight has not changed. It makes more sense to me. I was surprised to be at 32% with 10 pounds heavier. So I guess this challenge is completed!!!
