Congrats on your SVs, Han, yumyum
TDEE = Total Daily Energy Expenditure, the estimated number of calories you burn in a day, is calculated from your current weight, height, age and activity level: TDEE Calc
In an average week, you burn about 7 x TDEE, so to lose say 1lb per week, you theoretically need a 3,000 calorie weekly deficit,
e.g. if your TDEE = 2,000, you burn about 14,000 cals weekly, so eating only 11,000 should lose 1lb.
BurgerBob If you calculate your TDEE, using activity level "lightly active" we could estimate what you would theoretically lose.
BUT if you have thyroid / blood sugar issues / PCOS / some medications / have been dieting for years ...... you may lose more slowly than that.
Yumyum Daily 800 cals should enable weight loss for almost everyone, provided those cals aren't junk or booze.
However, those with blood sugar problems, e.g. preT2, need to also reduce insulin levels, which means low carb and cutting out starchy carbs.
The weight loss phase of any diet is always stricter than maintenance.
Both the book and the Newcastle Uni research on which it is based recommend:
Weight loss
. NO starchy carbs, except beans, lentils & peas.
. Also NO alcohol.
Weight Maintenance
. Small side portions of starchy carbs.
Dr M in his webchat said e.g. 1 slice of wholegrain bread with a meal
. Optionally a glass wine, but a,ways stay within nhs limits.
In both cases, the BSD book and website accept many people can't manage this 100% of the time. However, the more you stick to the BSD rules, the better it works.
