Dont get depressed . stress and
depression also cause weight gain.
thyroid problem(
hypothyroidism) and diabetes will influence your body weight.kindly follow the proper medication,diet and exercise.
Advise to Diet and lifestyle:
Be hydrated.take 3-5 litres of water.
regarding your intake take less
carbohydrate foods. ideally eat nutrient nourished food.
Add more leafy vegetables like spinach,gourd,cucumber,(avoid cabbage and cauliflower that will influence thyroid problem)
Add nuts Like almond,peanut,channa (recent studies says intake of nuts will not increase weight in diabetes patient.)
make your diet into 5 times/day. but your total calorie intake should remain the same.
Add millet(ragi,bajra like food)multi grain food pattern will help you in reducing weight.
Your joint pain and
tiredness all because of your thyroid/diabete/
