A tough weight loss question this week. Let’s dive straight in
A popular diet for weight loss is Zone diet. It has 30 % calories from proteins, 30 % calories from fats and 40 % calories from carbohydrates. Unfortunately, you didn’t give height/weight, so I can’t estimate the number of grams, but here’s an example:
5′ 8" girl is 170 lbs and wants to lose weight. Her starting BMI is 25.9.
If she went down to BMI 22.0 she’d be about 145 lbs. With a bit of light exercise she’d need 2000 calories to maintain her weight at 145, and might need to cut to about 1750 or 1700 calories to lose weight safely at 1 to 2 lbs per week. BMI isn’t always right, but it’s pretty good for average people who are not professional athletes or body builders. Each gram of fat is worth 9 calories, so when losing weight on 1750 calories x 30 % fats / 9 calories/g = 58 g of fat in diet per day. No more than 10 g should be saturated fats according the the US govt suggested diet.
