Can anyone help me?
I'm a 32 year old women, very sedentary (have an office job & working from home in lockdown), 5 ft 8 or 9 & currently weighing 193 pounds,
Fat secret gave me a caloric intake goal of 1,800 to lose weight & i've been eating less than that every day - sometimes much less (I really want to lose the weight),
I'm used to eating much more than this & maintaining (2-2,500 on a normal day) and i've not had a healthy diet for a long time. In the past when i've gone on diets i.e. slimming world, i've lost around 2 pounds per week.
This time i've switched to much healthier foods (less carbs, more healthy fats (nuts, avocado, olive oil) & lots of fish & veg) because I really want to change my relationship with food and my body & eat the things they say are good for you.
The first week went well - I lost 4 pounds

However, this week i've gained a pound of that back...
My caloric intake this week has been the following:
5th - 1663
6th - 1549
7th - 1564
8th - 1390
9th - 1726
10th - 1320
11th - 1334
To give you an example of what i'm eating on a normal day:
Breakfast - 2 Weetabix, milk & strawberries or bananna
Lunch - Chicken breast or Goat's cheese salad (Baby leaf, cucumber, cherry toms, onion, celery, beetroot, sometimes extras like gherkins or a few olives or 1/2 avocado)
Snack - Very small portion of nuts (i.e. 5 cashews), 2 squares of dark choc, apple & 6 grapes
Dinner - Baked Cod fillet, Chickpeas with onions, broccli & grean beans
Snack - Sugar free jelly & a mandarin or fat free yoghurt & berries
I've also switched to only drinking water with lemon & the occasional sugar free squash.
For me, this is literally the healthiest I have ever eaten!
I am tired ALL THE TIME, often hungry and fighting to ignore it, but I so desperately want this change.
However, gaining a pound this week has really thrown me - I just don't know what i'm doing wrong? I feel really depressed about it... I don't feel like I can keep up this low a calorie intake forever, and so I was hoping to see good results...
If anyone can help, offer me some reassurance or some pointers if you can see where i'm going wrong, it would be much appreciated
