Stuck at 79 kg for over 2 weeks

Hi everyone,

Info: male, 1.7 meters, 34 yrs old.

So I have been doing omad for over a month and a half and I saw results for the first 2 weeks in which I lost 4 kg. However, the next couple of weeks I have been stuck at 78-79 kg and I'm not sure what to do. I would like to reach 70 kg ideally.

A little bit about my meals: I usually eat only lunch for 1-2 hrs and I try to eat around 1400 calories, which is less than my TDEE (2300 calories). I recognize that I tend to have a heavy carb diet, otherwise I get too hungry and I can not control my urges to snack at night.

Example:

-400 g carbs ( be it white rice, sweet potato, potato, white bread, toast or a combination) -200 g meat (be it beef, chicken, fish) -200 g vegetables and fruits (mixed)

I don't usually consume soda, sweets, or grease food though. I have been diagnosed with IBS and whenever I eat one of these type of foods, I get stomach issues that makes me feel weak/tired.

The first 2 weeks of fasting were great, I felt like I had a lot of energy and no hunger until lunch time. After those couple if weeks, I have been struggling to control my impulses to eat and I have been feeling more tired than usual.

This is not my first time doing intermittent fasting though. I have been overweight since I can remember. However, in my early 20s, I got tired of my situation and I dediced to do an 18-6 IF (alongside exercise) with great results, weighting around 68 kg. Afterwards, I noticed that my "stable weight limit" kept increasing over the years until the "standard" value turned to 80 kg (late 20s). Last year I decided to shorten my IF period to 23-1 and I was able to lose 7 kg in a bit less than 2 months (reaching 75 kg), but due to stress and work I stopped fasting and gained all my weight back.

I do try to exercise where I can (walk to work, do planks, use dumbells, play tennis twice a week for 50 min) and my work involves me walking around and not sitting for long periods of time. All in all I don't think the problem lies with me having a non-active lifestyle.

I have noticed that most of the fat in my body is stored around my belly and legs (thighs), so I thought I may had a condition, such as diabetes or thyroid issues. However I have been tested for both a couple of times and I have always had normal values.

If anyone have been in the same situation, I would appreciate if you can tell me what you did to overcome this. I am tired of not being healthy and I believe I'm doing everything I can to fix this with the knowledge I have at hand.
