Even without knowing your age and waist Id still suggest simply eating at your BMR for your target weight.
Currently your BMR is roughly:
20 years: 1588 calories
30 years: 1541 calories
40 years: 1494 calories.
Applying a sedentary activity of 1.2 and your current maintenance intake is approximately…
20 years: 1905 calories
30 years: 1849 calories.
40 years: 1792 calories.
Assuming your goal is to get to about 138lbs then your BMR at that weight is roughly
20 years: 1457 calories
30 years: 1411 calories
40 years: 1364 calories.
Giving you a daily calorie deficit of around 450 calories or around 3150 calories a week. No real need to go below your target BMR and any exercise/activity you decide to take will of course increase that deficit but you should see a minimum of 1lb loss every 8 days.
In terms of going 100% Huel that would mean that you would need
20 years old: 361g Huel a day
30 years old: 350g Huel a day
40 years old: 338g Huel a day
(Split between however many meals suits you)
If incorporating fruit into your plan then you may be looking at around 90-100 calories per fruit option.
If that’s the case then reduce the amount of Huel by approximately 25g per 100 calories of fruit consumed. 1g of Huel is roughly 4 calories.
